09:02 < notmike> You're right. That was uncalled for. I'll ban myself now.
09:02 < jim> if there's even one woman here, you just made her feel like crawling under a rock for about 10 years
09:02 < jim> so...
09:02 < jim> be -careful-
09:04 < xdije> hi
09:04 < aaa_> hi
09:05 < xdije> after i finished rsync a huge data to new location, if i run the rsync again with -o in addition will this cause the data to sync again or only the owner attribute will be sync
09:07 < jim> I'm pretty sure some kinds of rsync will compare the file hashes
09:09 < madghost> https://ibb.co/bPgh6c
09:09 < madghost> that is my example :(
09:09 < madghost> why doesn't work ?
09:10 < madghost> windows has 192.168.1.3 ip address
09:17 < jim> I guess 0.0.0.0 is probably special
09:20 < jim> we should probably try again... I'll be right back
09:20 < madghost> route add default gw 192.168.2.1 get me SIOCADDRT: Network is unreachable as well :((((((
09:29 < jim> can you run ... route -n > ~/route-listing
09:36 < jim> to add this default route: route add default gw 192.168.2.1, you need already a net route like this: route add -net 192.168.2.0/24
09:36 < jim> in other words a net that the gateway is on
09:37 < jim> it's actually -two- routes, the net route and the default route
09:37 < madghost> I did route add 192.168.2.0/24 and ping 192.168.2.1 works
09:38 < jim> ok, now try to add the default route (now that you can reach the gw)
09:38 < madghost> but when I try to do: route add default gw 192.168.2.1 it gives me SIOCADDRT: Network is unreachable
09:39 < jim> ok, do this... route del 192.168.2.0/24
09:39 < jim> then route add -net 192.168.2.0/24
09:40 < jim> maybe you have to add the netmask separately like in the old days
09:41 < jim> but let's try this for now
09:41 < jim> wait, you're on the net now... on a different machine?
09:41 < madghost> I can't (((((
09:42 < madghost> cause this computer is other city, and then I do it, I don't want to go there :((((
09:42 < jim> when will be tne next time you go there?
09:43 < madghost> I hope not soon
09:43 < madghost> )))
09:43 < jim> or is it just too far?
09:43 < madghost> yep (
09:43 < jim> ok
09:44 < jim> what had you want to do all this?
09:45 < madghost> I don't know (( I will read about routing in Linux, and maybe something find. Thanks for time on me
09:46 < jim> you'll want to learn ip route command
09:46 < madghost> I emulate this problem on other computer, and will find a solution
09:46 < madghost> thanks
09:47 < jbit> madghost: the network route needs to be link local
09:47 < flipper887> It took a month but using Lubuntu 16.04.4 on the 4.4.0-x series of kernels i was able to get  thoes amdgpu-pro drivers up and running.
09:47 < jbit> sounds like it's not, and that's why it thinks hte address is unreachable
09:48 < jbit> madghost: you need to do like "route add 192.168.2.0/24 dev eth0" (or whatever your ethernet adapter is)
09:49 < naim42> madghost: what's with the ((((( ?
09:49 < madghost> I did it, and my network thru dev enp10s1
09:50 < madghost> 192.168.2.0       192.168.1.254       255.255.255.0   UG    0      0        0 enp10s1
09:51 < madghost> 64 bytes from 192.168.2.1: icmp_seq=1 ttl=59 time=0.912 ms
09:51 < jbit> madghost: the "G" means it's a global route, and not link local
09:52 < jbit> madghost: sorry, that's slightly misleading... the "G" means it uses the gateway
09:56 < jim> so it's working now?
09:56 < jim> maybe there's a bad route or something unfortunate in iptables
10:02 < okamis_> I dont understand readlink command. E.g. the -f flag, refers to component, and all but the last component must exist. What is a component?
10:03 < the_drow> How do I connect two computers with an Ethernet cable (without a router) and ensure that a route between the two computers is established automatically?
10:04 < MrElendig> okamis_: a part of a path
10:04 < MrElendig> the_drow: set up a profile in your network manager
10:04 < autopsy> the_drow, you need a poatch cable to do that it is specific.
10:04 < MrElendig> autopsy: no
10:04 < autopsy> MrElendig, no patch cable?
10:05 < okamis_> MrElendig: Last component, would that be the filename?
10:05 < MrElendig> the_drow: or run dhcp server on one of the machones
10:05 < MrElendig> autopsy: you need a ethernet cable of some kind, and I suspect that you are confusing patch with crossover
10:05 < autopsy> MrElendig, if you don;t use a patch cable the connectors are reversed so it won't work ethernet to ethernet.
10:05 < MrElendig> autopsy: there is nothing special about a patch cable, except that they are usually stranded
10:05 < the_drow> MrElendig, How do I do that?
10:06 < autopsy> MrElendig, yeah a crossover cable sorry.
10:06 < the_drow> autopsy, I know
10:06 < MrElendig> autopsy: that is a crossover cable, not a patch cable, and any hardware made in the last decade as auto-mdi/mdix
10:06 < MrElendig> autopsy: all gbit cards has it because it is required in the standard
10:06 < the_drow> MrElendig, also known
10:06 < MrElendig> so not corssover cable needed in the wast majority of cases
10:06 < autopsy> MrElendig, ok you're right I'm referring to old cables.
10:06 < aloy> okamis_: the last component in foo/bar/baz will be 'baz', with -f, the path foo/bar must exist, baz doesnt have to exist
10:07 < MrElendig> autopsy: not old cables no, it was not due to the cables, it was due to the electronic at each end
10:07 < MrElendig> autopsy: some devices had a physical switch to switch between mdi and mdi-x btw
10:07 < the_drow> How do I configure the NetworkManager to create the route automatically?
10:07 < rendar> rasberry freezed, i have booted it again and now my external ext4 driver can't be mounted: journal is corrupted...is ext4 so fragile?! it's a power black out enough to destroy a ext4 fs?!
10:08 < the_drow> I can find info about using ip ad add but not with network manager
10:08 < autopsy> the_drow, can't you set it in /etc/sysconfig/network-scripts/ifcfg-eth0 as GATEWAY=192.168.43.1 ?
10:08 < the_drow> I'm not sure
10:08 < the_drow> The thing is, sometimes the ethernet card is connected to a router and something it isn't
10:08 < MrElendig> rendar: no filesystem likes unclean shutdowns
10:09 < rendar> MrElendig i know, but in +30years of NTFS, FAT32 and FAT16 it never happened!
10:09 < MrElendig> rendar: and you just don't notice all the times it have happened where there wasn't any journal corruption afterwards
10:09 < MrElendig> rendar: lol
10:09 < the_drow> The computer in question has two network cards, one that goes into the router and the other to another computer. We have no way to know which is connected to which in a customer's deployment
10:09 < autopsy> the_drow, well if you're not using DHCP you can set the default gateway with route command.
10:09 < MrElendig> rendar: fat doesn't have a journal, there you just get data corruption with no aparent errors instead
10:09 < MrElendig> :p
10:09 < aaa_> dns over dhcp
10:10 < MrElendig> and ntfs likes to blow up too
10:10 < peetaur2> fat is so modern...glad to see it used in EFI
10:10 < MrElendig> atleast it is not riddled with patents
10:10 < the_drow> Please explain this to me like I'm 5
10:11 < the_drow> Because I've done some stuff but not this
10:11 < autopsy> the_drow, that just sounds silly why are they unplugging the cables and mismatching them afterwards?
10:11 < peetaur2> rendar: oh...we're talking about raspi? is it an SD card? rapsi is notoroious for corrupting things due to hardware, not software's fault.... use a card on this list  https://elinux.org/RPi_SD_cards
10:12 < autopsy> the_drow, use route add default gw 192.168.0.1
10:12 < MrElendig> you can use arp do somewhat reliable detect what is at the other end
10:12 < peetaur2> s/notoroious/notorious/
10:12 < MrElendig> but this is a "why are you doing this in the first place?" kind of thing
10:12 < autopsy> MrElendig, why is the customer mis matching the ethernet cables though?
10:13 < autopsy> the_drow, they should know to keep them plugged into the right RJ-45 port.
10:13 < the_drow> Ok so one computer is connected to the ethernet, the other is isolated from the intranet. The other is also connected to instruments measuring some stuff and it transmits them over LAN
10:14 < the_drow> autopsy, We can't tell how they will deploy the product
10:14 < autopsy> the_drow, I see.
10:14 < autopsy> the_drow, what instruments?
10:14 < NGC3982> i am about to build a live feed for my web site. i have an old smart phone i will use for this, and some kind of scheduling. my initial solution is to build a tasker script that takes a picture every minute, which in turn uploads it and replaces a picture shown in an automatically updated html document. im doing this on my standard apache server. any suggestions on how to do this "more properly", or is
10:14 < NGC3982> this actually a good solution?
10:14 < the_drow> autopsy, Naval sensors
10:15 < the_drow> It is also likely a customer will connect a sensor directly to a computer with an Ethernet cable
10:16 < autopsy> the_drow, your sensors have RJ-45 jacks?
10:17 < autopsy> NGC3982, doesn't sound like a feed of video.
10:17 < the_drow> autopsy, yup
10:17 < autopsy> NGC3982, Every minute is kinda long for it to be a feed.
10:17 < the_drow> Sometimes only them
10:18 < autopsy> the_drow, so what are you asking here is the real question the ethernet cables might be plugged into the wrong port for your deployment?
10:19 < autopsy> the_drow, routers can do DHCP or static addressing.
10:19 < the_drow> They might be connected to any port that is available or even disconnected from the Intranet in order to connect it to a sensor
10:19 < the_drow> autopsy, But they are unwilling to connect these sensors to routers
10:19 < the_drow> Oh don't ask why
10:20 < MrElendig> wouldn't need a router, just some controller which runs dhcp
10:20 < MrElendig> and it would make your life a lot simpler
10:20 < MrElendig> sidenote: this is less of a issue if everything supports ipv6 slaac
10:22 < autopsy> the_drow, you need to use a dhclient script maybe.
10:22 < the_drow> MrElendig, So if I have dnsmasq can I set it up?
10:22 < MrElendig> sure
10:22 < MrElendig> and have all the sensros send a id/hostname in the dhcp request, so that you can automagically do dns
10:22 < MrElendig> or use mdns
10:23 < MrElendig> because having a hardcoded list of ip addresses is silly
10:24 < autopsy> MrElendig, maybe he doesn't want them to change ever.
10:24 < the_drow> MrElendig, not all sensors have a hostname. Some are just FPGAs
10:25 < MrElendig> autopsy: hardcoded lists works until the day someone makes a single mistake and then the oven catches fire
10:25 < MrElendig> been there, seen that (and spent two weeks redoing a lot of cabeling due to it)
10:25 < the_drow> Anything can connect to our product
10:26 < the_drow> But we need to set up a computer to another computer LAN first. I don't know the hostnames in advance
10:26 < autopsy> MrElendig, yeah but it's only two RJ-45 jacks he's worried about.
10:27 < autopsy> the_drow, you can use iptables and forwarding to reach the internet from the LAN computer.
10:27 < NGC3982> autopsy: true. still, i dont think i need more than every minute. its for monitoring plants.
10:27 < s10gopal> how to disable "hwclock --systohc" during shutdown ?
10:27 < autopsy> the_drow, are you trying to reach the internet from both computers?
10:27 < NGC3982> autopsy: still, sounds like a reasonable idea, or a botch job? :/
10:27 < autopsy> s10gopal, is your distribution using systemd?
10:27 < NGC3982> i do not really know what services exist for this already.
10:27 < s10gopal> autopsy, no upstart
10:29 < autopsy> s10gopal, it's in /sbin/init I think when the shutdown proceedure is going. Check if /sbin/init is a text file script or a binary file.
10:29 < s10gopal> autopsy, thx for help , bugzbunny is helping me on #ubuntu
10:29 < autopsy> s10gopal, did you get it fixed yet?
10:29 < s10gopal> autopsy, no
10:30 < autopsy> s10gopal, on your machine you should have /sbin/init
10:31 < autopsy> s10gopal, upstart SYSV init and systemd all differ across the many available distributions.
10:31 < autopsy> s10gopal, or /etc/rc.d you should have also.
10:32 < BCMM> autopsy: curious - on which distros is init a text file?
10:32 < the_drow> autopsy, no, I'm trying to reach the intranet only from one
10:32 < BCMM> (also, missing option - on Debian Sid, by default, it's a symbolic link to /lib/systemd/systemd)
10:32 < autopsy> BCMM, on Fedora's old LiveCD initramfs it is a nash shelll script.
10:32 < s10gopal> autopsy, content of /sbin http://paste.ubuntu.com/p/3H7WyfYVB4/
10:33 < BCMM> autopsy: presumably one that does a few weird liveCD things, and then execs real init?
10:33 < autopsy> BCMM, yes it does pivot_root $newroot /sbin/init
10:34 < s10gopal> autopsy, and init is binary file
10:34 < BCMM> autopsy: oh, i missed that you said initramfs. that's not an unusual configuration for an initramfs
10:34 < autopsy> s10gopal, ok so forget that approach.
10:34 < s10gopal> autopsy, #ubuntu also dont know about upstart
10:34 < s10gopal> <guiverc> s10gopal: i have no idea; maybe /etc/default/hwclock  (it overrides some settings found in hwclock.sh
10:36 < autopsy> s10gopal, nah you need to find the call to the binary in your initialization system The one that controls what happens on shutdown or Runlevel 0 and runlevel 6
10:36 < s10gopal> autopsy, how ?
10:38 < BCMM> i'm sorry, but the idea that it's normal for that to be called directly by /sbin/init is just wrong
10:38 < BCMM> it will be an init script (service) that does it
10:39 < BCMM> and /etc/default/hwclock *should* modify the behaviour of that script (but it's also *possible* that that file is just a holdover from debian and the ubuntu script doesn't actually check it)
10:40 < Ben64> oh man this is annoying
10:40 < Ben64> sometime between when i learned how to use inkscape and now, they decided to remove Object -> Objects
10:40 < Ben64> now i don't know where to see a list of objects
10:41 < BCMM> Ben64: what version?
10:41 < Ben64> 0.91
10:42 < s10gopal> autopsy, BCMM,  can i install systemd on ubuntu 14.04?
10:42 < the_drow_> MrElendig, Is there a tutorial or something I can read on how to do it?
10:42 < the_drow_> autopsy, ^
10:44 < BCMM> s10gopal: you *can*, you probably *shouldn't*. stuff will break.
10:45 < BCMM> s10gopal: any particular reason for not running a newer ubuntu?
10:45 < BCMM> s10gopal: you've still got support for another year on 14.04, but there's been a new LTS out for a while
10:46 < s10gopal> BCMM, https://bugzilla.kernel.org/show_bug.cgi?id=198665 , if u use old kernel on ubuntu 16.04 laptop becomes super laggy
10:46 < BCMM> s10gopal: well, there's a *new* new LTS coming this month
10:47 < BCMM> so i guess that might solve your problem
10:47 < s10gopal> i dont happen upto kernel 4.12
10:47 < s10gopal> 4.13 onwards it happen
10:48 < autopsy> s10gopal, I am a Fedora user I don't know about upstart either.
10:50 < s10gopal> autopsy, plz for giving your precious time
10:50 < autopsy> s10gopal, I have to check google for upstart on shutdown proceedures I don't have Ubuntu.
10:50 < s10gopal> http://paste.ubuntu.com/p/GMP8PMKxFB/
10:50 < autopsy> s10gopal, why do you want to disable hwclock --systohc anyways?
10:51 < BCMM> that's a good question
10:51 < s10gopal> https://bugzilla.kernel.org/show_bug.cgi?id=198665
10:51 < s10gopal> a developer told me
10:52 < autopsy> s10gopal, ahh you found it that looks like it right there what file is that actually?
10:52 < autopsy> s10gopal, what is the full path name?
10:53 < s10gopal> i did cat /etc/init/hwclock-save.conf | pastebinit
10:56 < autopsy> s10gopal, so everything is in /etc/init now that you found it edit it in a text editor like gedit and comment out that line #exec hwclock --rtc=/dev/rtc0 --systohc $tz --noadjfile $badyear       After you put in a pound sign before the call to exec hwclock save the file and reboot to test it.
10:57 < s10gopal> autopsy, thx
10:58 < autopsy> s10gopal, you can use nano or vim too to edit files of type text.
11:05 < s10gopal> autopsy, done , how i can verify that it is disabled on shutdown?
11:13 < autopsy> s10gopal, switch to runlevel 0 or runlevel 6 using /sbin/init 6
11:14 < autopsy> Runlevel 0 is a poweroff and runlevel 6 is a reboot.
11:16 < s10gopal> autopsy, can you please guide me how i can learn linux kernel and driver development ? from where i should start ? i only know very basic linux commands and little bit c programming
11:19 < autopsy> s10gopal, I've been reading the manual pages on system calls in C
11:19 < autopsy> s10gopal, you want to develop drivers in C?
11:19 < s10gopal> autopsy, yes
11:20 < kurahaupo> s10gopal: what sort of things do you want to write drivers for?
11:20 < s10gopal> kurahaupo, for embeded devices
11:21 < milp_2> hi, could anyone give me advice how to tell openvpn not to route intranet-subnets through vpn? As soon as i connect my office machine to vpn i cant access any of the intranet-subnets anymore
11:21 < kurahaupo> Lots of devices already have drivers; what do you expect doesn't?
11:22 < kurahaupo> milp_2: use different subnets at each end. If that's not possible, use 2-sided NAT
11:23 < s10gopal> kurahaupo, still new devices are coming
11:24 < milp_2> kurahaupo: this is a normal anonymity-vpn provider, nothing on my own. cant i just tell it to ignore all internal requests and only work as gateway for ther est?
11:24 < haventermianl> hi, someony can help with alipne and web.de? How to show all folders?
11:24 < kurahaupo> milp_2: what does "ip route show table all" look like before and after connecting the vpn?
11:25 < kurahaupo> milp_2: this should be the default behaviour so first we need to figure why it's going wrong
11:26 < peetaur2> s10gopal: http://kernelnewbies.org/
11:26 < s10gopal> peetaur2, thx
11:26 < kurahaupo> milp_2: and "ip -o addr show" for good measure
11:54 < kuri0> Do applications ever store sensitive data in /usr ?
11:55 < autopsy> kuri0, sensitive in what manner?
11:55 < kuri0> autopsy, ssh keys passwords and stuff like that
11:55 < sauvin> And what applications?
11:56 < sauvin> Mostly, applications that *users* run can't do that.
11:57 < autopsy> kuri0, oh hell no.
11:57 < kuri0> autopsy, so its safe to run an untrusted application in sandbox giving it read only access to usr ?
11:57 < kuri0> *assuming the sandbox is secure*
11:58 < autopsy> kuri0, are you afraid of someone hacking the machine?
11:58 < kuri0> autopsy, i use a sandbox for untrusted stuff from github
11:59 < autopsy> kuri0, what is an untrusted application?
11:59 < kuri0> autopsy, application which could be malicous
11:59 < junka> what is a sandbox
11:59 < autopsy> junka, like a jail.
12:00 < junka> does it have a name?
12:00 < autopsy> kuri0, I'd check the source code of any untrusted application first.
12:00 < kuri0> autopsy, what about if it has no source ?
12:00 < kuri0> junka, i use bubblewrap
12:00 < junka> oh
12:00 < autopsy> kuri0, then you aren't providing it under GPL like the kernel.
12:01 < sauvin> Untrusted stuff like that, run it in a VM that has no net access.
12:04 < junka> kuri0; why not firejail
12:04 < kuri0> idk
12:04 < kuri0> i just used bubblewrap
12:04 < kuri0> is firejail better ?
12:05 < sine0> I tried to migrate a client to another host for ecommerce, alot of hte filenames are in chinese for the pictures. when I scp/ftp the files over they become url/unicoded and the file urls are invalid
12:05 < junka> kuri0; seems easier
12:05 < sine0> I hate tried testing this with local box and the same happens, so what gives and how can I fix this? would it be down to the host locales and therfor I would be limited in what the would enable ?
12:06 < kuri0> junka, bubblewrap seems to allow more configuration too
12:08 < kuri0> junka, also firejail is a suid binary which requires root ?
12:09 < kuri0> i installed bubblewrap from source without needing root
12:10 < kurahaupo> sine0: scp just copies the bytes of the filenames; check that you have the same locale settings at both ends
12:11 < sine0> kurahaupo: sure, so I guess if its a paid host, I would not have control over that, right ?
12:11 < junka> kurahaupo; i think so
12:12 < bipul> What could anyone assume? if we get this output while installing any package via apt "E: Sub-process /usr/bin/dpkg returned an error code (1)"
12:13 < lupine> bipul: I'd expect to see some error output from dpkg in that case
12:13 < bipul> What's the meaning of "dpkg returned an error code (1)" ?
12:13 < autopsy> bipul, maybe a package scriptlet failed to run properly to completion.
12:13 < kurahaupo> bipul: what error is reported if you run dpkg directly?
12:14 < lupine> the meaning is exactly what it says. `dpkg ... ; echo $?` would output 1
12:14 < bipul> kurahaupo, where will i get the error report?
12:14 < kurahaupo> Stderr
12:15 < autopsy> bipul, doesnt apt have an error log mechanism?
12:15 < autopsy> I call it a mechanism.
12:16 < bipul> autopsy, Yes it has.
12:16 < autopsy> bipul, I know dnf has a history list it can undo actions it already completed using that history list.
12:16 < autopsy> bipul, what is the norm for error logs in dpkg?
12:17 < bipul> autopsy, https://paste.ubuntu.com/p/QG56TJdpJv/
12:20 < bipul> autopsy, https://paste.ubuntu.com/p/PPtTGhKryh/  /var/log/dpkg.log
12:26 < azarus> I'm trying to decide between 3 wireless cards. One is the Intel Wireless AC 7260, one is the Compex WLE600VX and the other Compex WLE600VX.
12:26 < azarus> The Intel one is supported by iwlwifi, the others by ath10k.
12:27 < Polar_Bear> I am having some trouble with grub2. I skipped installing it when installing the rest of debian stretch earlier, which I have dual booting in UEFI mode with windblows10, so its normal install scripts didn't get to run. I've since installed the package since, but haven't got grub-install to play nicely. I think it's trying to install it in MBR mode and is failing with the message "grub-install: error: will not proceed with blocklists."
12:27 < azarus> Which ones will prove less problematic, and which ones will have better speed?
12:29 < dgurney> all of them will probably work just fine
12:30 < dgurney> I've never had problems with Intel or Atheros cards
12:30 < azarus> I'll probably go for the Compex WLE600VX, as it uses less power and support 802.11AC
12:30 < dgurney> okay then
12:30 < MrElendig> Polar_Bear: --target
12:37 < bipul> could i expect the solution of my problem which i have shared?
12:42 < Polar_Bear> MrElendig, thanks. That doesn't get me any further. If I specify --target=x86_64-efi I just get "grub-install: error: /usr/lib/grub/x86_64-efi/modinfo.sh doesn't exist. Please specify --target or --directory"
12:43 < Polar_Bear> should I be mounting the efi partition somewhere special first?
12:43 < MrElendig> find out which package owns that file and install it?
12:44 < MrElendig> azarus: ath10k is a steaming pile of crap
12:45 < MrElendig> azarus: https://media.ccc.de/v/32c3-7375-wireless_drivers_freedom_considered_harmful
12:45 < MrElendig> not that iwlwifi is much better
12:47 < autopsy> bipul, check dpkg logs
12:47 < autopsy> 02:00.0 Network controller: Ralink corp. RT5390R 802.11bgn PCIe Wireless Network Adapter
12:47 < autopsy> MrElendig, is RaLink no good?
12:48 < bipul> autopsy, Are you referring to this /var/log/dpkg.log ?
12:49 < MrElendig> autopsy: ymmv
12:49 < MrElendig> and do watch that video
12:49 < autopsy> bipul yes use tail on that file.
12:49 < MrElendig> also wireless.kernel.org
12:50 < EdLin> I can't seem to get alsa sound working in kernel 4.16 with my Ryzen APU....
12:50 < autopsy> bipul, paste bin your log file for me to look at about the error.
12:50 < EdLin> tried unmuting it, no joy
12:51 < MrElendig> lspci | grep Audio
12:52 < EdLin> https://paste.pound-python.org/show/rZSg4kGVBo1fdKHyRtsy/
12:52 < EdLin> only my video card and apu video audio is showing.
12:53 < oiaohm> MrElendig: its not just wifi drivers is all transmit software define radios.   Regulators around the world are a pain in tail with them.
12:53 < EdLin> I can't use the apu video, as I'm using DVI-D with it, and can't use the video card audio, as that's in a VFIO-bound video card for virtualization
12:53 < EdLin> MrElendig: ^
12:54 < MrElendig> oiaohm: it is perfectly possible to comply to the regulations without being assholes, sadly the wifi chip makers likes being evil
12:55 < oiaohm> MrElendig: not really.  https://www.law.cornell.edu/cfr/text/47/2.944   This is the 2005 regulation for you.
12:56 < oiaohm> MrElendig: you can fairly much bet on getting a blob of random unknown quality.
12:56 < MrElendig> oiaohm: the video actually covers this in part
12:57 < MrElendig> oiaohm: there is a difference between hardlocking certain settings and making everything a non-free blob and actively sabotaging people who write free drivers
12:57 < MrElendig> eg atheros are doing both of the later
13:01 < azarus> MrElendig: can't listen to video now, is there a tldr
13:01 < MrElendig> "we are screwed"
13:02 < autopsy> Is RaLink sabatoging people who writre free drivers?
13:03 < azarus> so -- buying a AC 7260 is preferable?
13:03 < oiaohm> MrElendig: Manufacturers must take steps to ensure that only software that has been approved with a software defined radio can be loaded into the radio. << Its the first bit of the regulation.  Where does this say that a software defined radio with open source is allowed as this is not taking all steps to prevent other stuff loaded into the raido.
13:03 < MrElendig> they are certainly not helping in any way, don't know if they are actively sabotaging the eforts
13:03 < oiaohm> Really if the regulation stated signed but source displayable would help open source drivers a lot.
13:03 < MrElendig> oiaohm: where does it say that that requires the software to be closed source?
13:03 < MrElendig> (it doesn't)
13:03 < autopsy> MrElendig, my wireless cards work fine here.
13:04 < azarus> I currently have a (ath9k supported) AR9285, but I'm longing for 802.11ac
13:05 < MrElendig> secureboot is an example where it is done without requiering that the software is closed source
13:05 < triceratux> MrElendig: i downloaded yesterdays swagarch 18.04 liveiso. the opera 51.0 download was going to take 2days. the firefox 59 download was going to take 2hrs. the wget brought it down in 9min. is there something weird about github.io that makes it particularly suited to wget ? https://swagarch.github.io/
13:05 < MrElendig> azarus: all the current AC chips are quite troublesome, including the intel ones
13:06 < junka> swag
13:06 < azarus> MrElendig: which ones are the least troublesome, in your opinion?
13:06 < junka> none?
13:07 < autopsy> What is AC?
13:07 < MrElendig> rtl and broadcom (cypress now really) requires out of tree drivers, the iwlwifi is quite buggy and the radio on the cards are not terrific (and ofcourse, pcie only)
13:07 < azarus> 802.11ac is a wireless standard, autopsy
13:07 < junka> NO ITS POWER SOURCE
13:07 < azarus> ALTERNATING CURRENT
13:08 < junka> fixed
13:08 < autopsy> Oh haha I got ya.
13:09 < autopsy> azarus, is AC better than BGN?
13:09 < MrElendig> unless you are american, then it is air condition
13:09 < MrElendig> autopsy: yes
13:09 < autopsy> MrElendig, how is it better?
13:09 < triceratux> anonymous coward ftw
13:09 < junka> am confused
13:09 < revel> I'm a nonymous coward.
13:09 < MrElendig> autopsy: better performance, deals with congestion better, supports beam shaping and more advanced power saving etc et
13:10 < autopsy> MrElendig, I got ya.
13:10 < oiaohm> MrElendig: with 802.11ac cards going to windows does not help you a lot of the time either.as they still load up the the same insanely stuffed up firmware.
13:14 < BluesKaj> Hi folks
13:15 < triceratux> sup
13:16 < autopsy> BluesKaj, hi.
13:17 < JimBuntu> heya BluesKaj
13:18 < BluesKaj> hey triceratux, autopsy, just morning coffee atm...trying to wake up :-)
13:18 < triceratux> BluesKaj: yep coffee is a priority. i moved out of that lousy neighborhood & theyre not vandalising & stealing my car so much
13:18 < autopsy> BluesKaj, its 4:18 AM here.
13:19 < JimBuntu> Pacific Time
13:19 < BluesKaj> autopsy, yeah EDT here
13:19 < autopsy> JimBuntu, are you asking if I'm using Pacific Time Zone?
13:20 < JimBuntu> autopsy, Not really, I was stating that the time you mentioned,... would also be true in the Pacific Time zone
13:20 < autopsy> BluesKaj, isn't it 7 AM where you're at then?
13:21 < JimBuntu> Eastern shows ~7:20am
13:21 < autopsy> JimBuntu, nah MST here Mountain Standard Time.
13:21 < autopsy> I'm in Arizona.
13:22 < JimBuntu> autopsy, Ah... in one of those areas that doesn't follow daylight savings
13:22 < autopsy> JimBuntu, yeah we don't have to switch our clocks here.
13:22 < BluesKaj> triceratux, so you've had changes in your life too. I'm still tring to deal with the death of my wife on Feb 6 ..totally unexpected, still in shock and disbief
13:23 < BluesKaj> disbelief actually
13:23 < JimBuntu> I'm saddened to hear that this is still leading to shock and disbelief BluesKaj... then again, I can only imagine what such a thing would be like, I have only lost parents
13:23 < autopsy> BluesKaj, you run Linux? How long?
13:23 < autopsy> Yeah that must suck.
13:24 < BluesKaj> JimBuntu, it's tough ...sometimes, but it's helped my family come together
13:25 < triceratux> BluesKaj: zomg thats actually serious. my best wishes at this difficult time
13:25 < BluesKaj> autopsy, been running linux for about 12-13 yrs , but just a home user
13:25 < BluesKaj> triceratux, thanks
13:28 < BluesKaj> gotta keep going tho ..linux helps me keep a routine every morning, it's my hobby
13:28 < autopsy> BluesKaj, how long have you been using Linux?
13:28 < BluesKaj> testing kubuntu bionic beta atm
13:29 < BluesKaj> autopsy, read above
13:29 < autopsy> BluesKaj, oh 13 years.
13:31 < BluesKaj> most people here are veteran linux users abd devs I would think ..right triceratux , you're an old timer so to speak ?
13:34 < triceratux> BluesKaj: my youth was misspent on cobol, cics, & windows. so im an oldtimer with computers but i didnt get around to linux until 2009. im a bonafide n00b compared to most of you folks. so i multiboot to try to recoup the experience i dont have
13:35  * triceratux is testing lubuntu-next 18.04 lxqt with the rebranded Falkon 3.0. qupzilla is no more
13:36 < autopsy> triceratux, I've learned a lot from Fedora's LiveDVD capabilities about Fedora Linux and it's development model.
13:38 < triceratux> autopsy: i keep the current fedora xfce spin bootable as a reference install. i dont run it for long periods because its a little more crashprone than some other distros. vital to know what those guys are up to tho
13:39 < autopsy> triceratux, so xubuntu has systemd?
13:41 < triceratux> autopsy: yep. all the buntus are systemd. there is no escape. except mx-17 & a few others
13:41 < BluesKaj> autopsy, since 14.04 yes
13:42 < MrElendig> but still with the terrible sysv compat enabled :/
13:42 < BluesKaj> well 14.04 was still non systemd
13:43 < triceratux> actually since 15.04. 16.04 was the first lts with systemd
13:43 < autopsy> Have they been slow to adapt systemd?
13:44 < triceratux> autopsy: nope they jumped right in once they made the decision. even beat debian by a few hours
13:44 < autopsy> triceratux, I see.
13:45 < autopsy> triceratux, isn't Ubuntu based on Debian?
13:47 < triceratux> autopsy: yep it is which is why they both switched at the same time. ironically its the ubuntu users who are slow to deal with systemd, because many of them only take lts seriously, & even then only after numerous point releases. so theres still a yuugh segment running 14.04 & the 16.04 conversions are ongoing even now
13:50 < JimBuntu> Why should the masses take none LTS seriously? If we are not testers, then why concern ourselved with non-LTS?
13:52 < triceratux> JimBuntu: thats exactly my attitude. canonical let you view the development cycle by way of the interim releases, but youre not forced to endure it if youre interested solely in a functional wellsupported system. works for me
13:53 < JimBuntu> triceratux, About the same for me. I listen/watch what is being said about non-LTS (regular) releases, but I don't use them... I can't imagine what it would be like to have to upgrade every ~9 months, lol, sounds a wee bit too MS like for me.
13:54 < kuri0> How can I extract the contents of a folder in a tar.gz ?
13:54 < MrElendig> man tar
13:54 < JimBuntu> yup kuri0 'man tar' is your friend.
13:55 < JimBuntu> kuri0, basically though, tar -zvxf <filename> <foldername>
13:56 < hehehe> hey folks
13:57 < BluesKaj> personally I found LTS releases more unstable in their early days than the non-LTS OSs, but as a tester I've never found LTS releases particularly advantageous over the non-LTS OSs as a general rule for a home user like me. Production machines are a differnt story i'm sure.
13:57 < revel> I don't think you have to specify -z with a tar.gz
13:57 < jim> hi
13:57 < ananke> nor '-'
13:57 < JimBuntu> Hiya jim
13:57 < lupine> well, you wouldn't use ubuntu on production machines anyway
13:57 < hehehe> I have mounted a vps in a rescue mode, then I have mounted the partition and used passwd - idea is to reset root pass
13:57 < JimBuntu> revel, I think you are correct, if will probably recognize it's a gzip and work by default.
13:57 < revel> Right, tar flags don't need - either.
13:57 < hehehe> is that all I have to do? i
13:57 < ananke> hehehe: yes
13:57 < jim> JimBuntu, heya
13:58 < revel> -v is technically not required either, but hey, it's nice anyway.
13:58 < JimBuntu> lupine, You can clearly use Ubuntu on production machines, lol
13:58 < JimBuntu> revel, very true, I like being verbose though ;-)
13:58 < lupine> yeah, but could isn't the same as would
13:58 < lupine> you can clearly also use windows on production machines
13:59 < JimBuntu> lupine, Ok then... I DO use Ubuntu on a few production machines, as do many others
13:59 < revel> Depends on the machines.
13:59 < lupine> condolences
13:59 < MrElendig> people use win95 on production machines sp..
13:59 < MrElendig> so*
13:59 < JimBuntu> lupine, in 10 years, no issues... please quantify your concern
14:00 < JimBuntu> MrElendig, Yes, many ATM machines (and banking computers in general, as well as medical facilities) do still use Win95, although, I don't really see the comparison
14:00 < lupine> dodgy upgrades, heavy churn, etc
14:00 < lupine> then there's the governance problems
14:00 < revel> Churn?
14:01 < lupine> e.g. most server distros have gone through one init system change in the last 10 years. ubuntu has gone through 2
14:01 < lupine> this is churn
14:02 < jim> MrElendig, is there something about earlier versions of windows that make it more suited as a remote server?
14:02 < jim> (briefly, I don't mean to derail present discussion)
14:02 < JimBuntu> "dodgy upgrades" -> I have not yet had an issue... churn? idk... governance, no issue at all as I can install various programs to handle better security, asset management, logging/etc...
14:02 < JimBuntu> Perhaps I am simply lucky.
14:03 < ananke> JimBuntu: or have a small enough number of systems where these issues are mitigated with hard work
14:03 < JimBuntu> jim, many companies had custom apps written around the time of Win95... apps that don't work 100% as expected on newer versions. That's the excuse I have been given time after time.
14:03 < cloudbud> how to remove  new lines in a file
14:04 < jim> oh ok, that makes sense
14:04 < JimBuntu> ananke, possibly... 40+ machines serving the general public 24/7/365.25 - No "hard" work, barely any work in regards to updates/etc (unattended mode active)
14:04 < ananke> cloudbud: first hit on google. seriously.
14:04 < rumpel> cloudbud, I'd look for "sedoneliners"
14:04 < jim> "new lines for old... new lines for old..."
14:04 < lupine> "I don't see it" isn't the same as "it's not there"
14:05 < lupine> but to each their own. you have my sympathies, and an install key of your choice if you ever do encounter any of the problems
14:05 < jim> cloudbud, do you mean remove the line endings so that what you're left with is one (unterminated) line?
14:06 < ananke> JimBuntu: which releases? I'd be curious as to your experience with dealing with such annoyances as automatically removing unused kernels, or the obnoxious automated install (although the latter is also shared with debian)
14:07 < hehehe> ananke are you sure?
14:07 < cloudbud> jim : I have a file that have a record then so many blank lines then another record then lines how can i remove the blank lines
14:07 < JimBuntu> ananke, LTS only, Everything is either 14.04.x ( a few dev boxes) or 16.04.x. Increase the /boot partition and never run out of space, or purge old kernels/etc once every few blue moons.
14:07 < hehehe> there suppose to be a change from # to some other sign
14:07 < ananke> hehehe: yes. _if_ you were using passwd from chroot, not just running 'passwd' period
14:07 < hehehe> I recall
14:07 < hehehe> ananke: how would I use passwd from chroot
14:07 < hehehe> i just run passwd
14:08 < ananke> JimBuntu: which exactly proves my point, it's a hackish solution that doesn't scale well
14:08 < kuri0> JimBuntu, doing that creates extracts the files in that folder to the folder with the same name
14:08 < kuri0> what i want is it to extract the files from that folder
14:08 < ananke> hehehe: you need to chroot to your root filesystem first
14:08 < JimBuntu> kuri0, then once you are done, mv the files from the folder into ./ or . if you prefer
14:08 < hehehe> ananke how?
14:08 < jim> cloudbud, oh, so you mean to remove the extra newlines (the ones that match spaces \n?
14:08 < ananke> hehehe: chroot /your/mounted/root/filesystem
14:09 < cloudbud> jim : yes
14:09 < hehehe> cool
14:09 < hehehe> ty
14:09 < hehehe> that is the missing bit
14:09 < ananke> cloudbud: 'blank lines' are not the same as 'new lines'
14:09 < JimBuntu> ananke, if I were inclined, I guess I could cron the apt purge, simple. Which distro do you suggest that doesn't keep previous kernels?
14:10 < JimBuntu> remove all lines that are only /r/n or /r or /n
14:10 < ananke> JimBuntu: distros better suited for production, where automation is necessary. rhel/centos/sles. you can easily define how many previous kernels you want to keep
14:10 < hehehe> ananke: ty
14:11 < JimBuntu> ananke, not a fan of rhel or centos, I'll check out sles, thanks.
14:11 < ananke> JimBuntu: ubuntu even in LTS mode is ill suited for what typically constitutes 'production'
14:11 < jim> cloudbud, I'd first look at those newlines and see if there are spaces before the newline
14:12 < cloudbud> jim : sample file https://pastebin.com/WDtEfMQD
14:13 < fSharp> hello, my encrypted luks partition rejects my correct password. after having tried all sorts of things to find the reason and open it, I can only reduce it down to two causes; 1. clipboard pasted the password incomplete (I saw that it happened with pasted passwords on gedit) 2. gnome disks on ubuntu 17.10. errorenously created the encrypted partition. have you had such experiences with these?
14:13 < lupine> centos shares many of hte same governance issues as ubuntu, unfortunately
14:14 < JimBuntu> Clouder, 'egrep -v " +" <filename> >output.txt'
14:15 < cloudbud> JimBuntu : not working
14:15 < JimBuntu> Clouder, please pastebin or termbin the terminal
14:16 < JimBuntu> Clouder, I saved your example file, and ran it with that command, only output was the non-space/CR/newline lines. perhaps your real file is different from example
14:17 < fSharp> are there any clipboard pasting errors that are seen with certain i.e. non-ASCII characters?
14:17 < NGC3982> hm, my system keeps telling me my grub is broken when i try to update.
14:17  * NGC3982 doesnt dare a reboot.
14:18 < cloudbud> JimBuntu : https://pastebin.com/WDtEfMQD
14:18 < the_drow_> What could cause a USB wifi stick not to connect to Wifi. demsg claims the link is not ready
14:18 < the_drow_> The firmware is there
14:18 < JimBuntu> cloudbud, same link?
14:18 < the_drow_> and loaded
14:19 < cloudbud> JimBuntu : https://pastebin.com/WDtEfMQD
14:20 < rockdarko> When doing the updates remotely on my dad's laptop I get something that makes me scared to reboot when pacman (Manjaro) runs grub config: Incompatible libdevmapper 1.02.146 (2017-12-18) and kernel driver (unknown version).
14:20 < rockdarko> Full output: https://darko.vision/pub/blackmage01
14:20 < JimBuntu> cloudbud, I have saved that file from raw, ran the egrep command, and it worked for me. What distro are you using and what is the output from 'egrep --version' ?
14:22 < cloudbud> JimBuntu : done
14:23 < Kingsy> is it possible to change any tray icon? I assume its a file somewhere you can replace if you find it/
14:42 < kuri0> JimBuntu, any way to do without that ?
14:46 < rocketmagnet> hi all
14:47 < rocketmagnet> i've a question: i'm using kali linux and i want to change the kernel boot parameters so they stay permantently, normaly i can do this with /etc/default/grub but since it's a live distro i've no idea where to put the kernel boot parameters so they stay when robooting
14:49 < spreeuw> if its a true live boot distro you cant
14:49 < spreeuw> unless you installed it rw somewhere
14:50 < spreeuw> or when you adjust the ro iso when creating the distro
14:50 < spreeuw> or enter it manually in grub each time you boot
14:54 < azarus> MrElendig: After watching that talk you linked (thanks, btw) I decided something like this is nice: https://v.gd/M4rO7O Supported by the mt76 driver
14:58 < autopsy> rocketmagnet, is it on a DVD or CD that you boot from?
14:59 < fSharp> are there any clipboard pasting errors that are seen with certain i.e. non-ASCII characters?
15:00 < fSharp> in other words, can copy-paste make errors with non-ASCII characters?
15:02 < JimBuntu> fSharp, it *could*, but I wouldn't expect it to, not specifically for non-ASCII...
15:03 < fSharp> JimBuntu, I created a luks partition by copy-pasting the password, and it doesnt open now. it is either the clipboard or gnome disk utility
15:04 < JimBuntu> fSharp, This should be somewhat easy to test... copy the password and paste it into a few different places, such as a text editor, possibly even a text editor set to something less than UTF-8 and see what happens
15:04 < JimBuntu> I'm not up on my luks/gnome disk utility... is there any chance your password was too long?... and was truncated?
15:05 < fSharp> JimBuntu, I tried it..the password in question is shown properly, but just yesterday I witnessed that non-ASCII was not copied from browser to gedit
15:06 < fSharp> so I wonder, even if it is shown properly now, maybe at the moment of partition creation something was missing.
15:06 < fSharp> whether or not that's possible
15:06 < fSharp> I dont think it is too long. longer passwords had no problem
15:07 < JimBuntu> fSharp, I'm unsure. I can say that since you asked, I went to a browser page with what I consider non-ascii chars... copied and pasted one (Chrome) and it worked fine. I may not be the best test subject though as I am using Synergy, which ties into my clipboard
15:08 < fSharp> yes, I guess it is not easy to detect if anything goes wrong
15:09 < fSharp> the other thing that comes to mind is having added c,a or v to the password while copy-pasting..but that brings a whole lot of combinations to test
15:10 < JimBuntu> fSharp, I guess it stand to reason that I should ask... is there anything in the encrypted partition that is worth the time/effort or do you have backups?
15:10 < fSharp> JimBuntu, I
15:10 < fSharp> I've been asking this, too..I think there is
15:11 < fSharp> backup..was the partition itself.
15:11 < fSharp> and the system has been reinstalled
15:11 < JimBuntu> ouchies.
15:12 < Hrtlnd> I have a VM a former assistant locked down so I can't get remote access to it through putty. I can log on locally, and I've tried to find where he did the lock down, but having no luck.
15:12 < Hrtlnd> I've checked IPtables port 22 is allowed for the entire subnet I'm on
15:13 < Hrtlnd> Is there another place I should look?
15:13 < JimBuntu> Hrtlnd, did you verify the SSH daemon is running?
15:14 < Hrtlnd> Yes, it's started
15:14 < fSharp> JimBuntu, thank you for your time
15:14 < JimBuntu> Hrtlnd, i.e. 'sudo service ssh status' and if running, perhaps a 'sudo cat /etc/ssh/sshd_config' to verify it's set to use port 22... or optionally, 'sudo netstat -tunelp | grep -i ssh'
15:14 < fSharp> I will see how/what I can do
15:15 < JimBuntu> fSharp, You are welcome.
15:15 < fSharp> bye!
15:15 < Hrtlnd> Running since 2017-11-26
15:16 < Hrtlnd> listening on 22
15:17 < JimBuntu> Hrtlnd, ok, does it only accept keys or also passwords? If it accepts keys and you can locally log in, verify the key you are using is properly set within the ~/.ssh/authorized_keys file
15:18 < JimBuntu> Hrtlnd, it would actually be good to see what error (if any) you are getting when you try to SSH in
15:19 < Hrtlnd> So one of the tasks I gave him over a year ago was to implement a process where an email was fired on login so we could see when a person had gained access as part of an audit trail.
15:19 < Hrtlnd> So when I SSH from my PC it takes me to logon, but password that works on console fails.
15:20 < xdije> when i run pvs i get  WARNING: Device for PV 9pFXew-uqNo-T6yR-emB5-1sRe-Bf34-0Bwvbj not found or rejected by a filter.
15:20 < Hrtlnd> It was supposed to be password only
15:20 < xdije> and is only for sbd
15:20 < azarus> Is it enough to have CONFIG_WLAN_VENDOR_MEDIATEK=y and CONFIG_MT7601U=m to have support for the mt76_pci driver?
15:20 < Hrtlnd> It's possible he created a key
15:20 < Hrtlnd> but he didn't supply me with one if he did
15:21 < Sitri> You should've supplied your public key...
15:21 < xdije> lvmconfig devices/filter     filter=["a|^/dev/mapper/mpath|","a|^/dev/sdb|","r|.*/|"]
15:21 < JimBuntu> Hrtlnd, I would check the /etc/ssh/sshd_config and the /home/<user>/.ssh/authorized_keys to be sure. I would suggest against ever letting passwords be used, but that's obviously up to you
15:22 < Hrtlnd> It's an internal server not internet accessible so I'm not majorly concerned
15:22 < autopsy> JimBuntu, I use secure shell to my online hosting account servers using a password all the time.
15:22 < JimBuntu> autopsy, Everyone is welcome to do as they wish :-)
15:23 < Hrtlnd> So /home is an empty directory
15:24 < JimBuntu> Hrtlnd, when the password fails, are you presented with a line that reads something like 'Permission denied (publickey)' ?
15:24 < JimBuntu> Hrtlnd, what distro?
15:24 < Hrtlnd> No, just Access denied
15:24 < Hrtlnd> I believe CentOS
15:24 < JimBuntu> Hrtlnd, are you logging in as root?
15:24 < Hrtlnd> Yes, root
15:24 < JimBuntu> ok, then check /root
15:25 < autopsy> Oh root over secure shell on a LAN.
15:25 < Hrtlnd> directory has an .rpm  file and that's it.
15:27 < JimBuntu> Hrtlnd, Ok, sounds like it's set up to accept a password, and there are no keys configured in the default way that I am aware of.
15:27 < JimBuntu> The port is open, since you get the Access Denied message
15:27 < Hrtlnd> So prior to his leaving I was able to log on to this server.
15:28 < Hrtlnd> I unfortunately was away on his leaving 3 days, and things were relatively amicable from what we could see.
15:28 < Hrtlnd> Since he left, we found some questionable stuff that makes us believe this was deliberate.
15:29 < JimBuntu> Hrtlnd, if there is any doubt, I would move the important data from the VM into a new one... never know what odd kind of tunnels could be lurking around
15:30 < Hrtlnd> Looks like that's the thing I need to do.
15:31 < Hrtlnd> Thanks for your help.
15:36 < autopsy> Hrtlnd, someone hacked your secure shell server or what?
15:38 < lowin> How do I make new policykit rules take effect? don't wanna restart the whole system
15:39 < Hrtlnd> No, former assistant left last year, I can only log on locally now, not ssh. The server is physically on-site and doesn't touch the net.
15:53 < xdije> my centos7 system hangs on Reached target Shutdown, untill i hard rest it, any explaination for this
15:55 < autopsy> xdije, why not just use Fedora 27?
15:56 < xdije> autopsy: it is a productive server
15:56 < Sitri> xdije: modern mobo?  Because really old systems didn't have a software means to tell the mobo to completely the shutdown.
15:57 < autopsy> xdije, yeah how old is the motherboard?
16:00 < xdije> autopsy: HP G9
16:01 < xdije> now while we are talking it has rebooted but took long time for that
16:07 < puff> I'm running google chrome on ubuntu 16.04 LTS.  Lately chrome has been spiking to 100+ % of CPU.  When I open the chrome task manager it's not some particular window or extension, it's "Browser".  This seems to be recent and it's incredibly annoying.  Anyone know what's going on?
16:08 < dysfigured> is there a way to review some log of processes run by a user?
16:09 < puff> dysfigured: Not particularly processes by user, though /var/log/* probably has some relevant info.  If you want to view logs *currently* run by some user, "ps -fu username"
16:10 < puff> dysfigured: Er, s/view logs/view processes/
16:10 < dysfigured> i have a vps i let a couple friends have accounts on, and i'm wondering about some sort of monioring system
16:10 < dysfigured> checking shell history isn't reliable..
16:11 < puff> dysfigured: That's correct.
16:11 < dysfigured> checking the current process list is only an instantaneous view, i'm wondering about tracking processes over time by specific users
16:11 < puff> dysfigured: Given the history of unix as a multi-user system, I'm sure there's something out there, but how much hassle it'll be to use it is another question.
16:11 < dysfigured> hell, myself and root too, good data as well
16:12 < puff> dysfigured: You could run a program that constantly logs the ps output.
16:13 < dysfigured> i was semi thinking there would be systemd logs somewhere
16:15 < puff> Good question.  I'm new at systemd so I don't know.
16:17 < monkeyisl> ln is like "shortcut" on windows?
16:18 < amosbird> hi, how can I clear the effect of sched_setaffinity() ?
16:24 < ayecee> set the affinity to all cpus
16:32 < Richard_Cavell> Hi everyone. I want to ask about the use of the ldd command.  Is this a good place to ask?
16:32 < ayecee> Richard_Cavell: one way to find out is to ask
16:32 < ayecee> about the use of the ldd command
16:32 < ayecee> not about whether it's a good place to ask about the use of the ldd command
16:33 < Richard_Cavell> I don't really understand how libraries work. I have some coding knowledge but I want to understand what the output of ldd means here:
16:33 < Richard_Cavell> <Krill> if you can't cure the cause, mitigate the symptoms!
16:33 < Richard_Cavell> oh dear hang on
16:33 < ayecee> heh
16:33 < Richard_Cavell> https://ideone.com/iPFgmY
16:33 < ayecee> site doesn't load
16:34 < Richard_Cavell> loads for me.
16:35 < ayecee> there it goes
16:36 < ayecee> now, what's the question
16:37 < Richard_Cavell> lines 9 through 11... I completely don't understand them
16:37 < kabads> It's DNS and I'm beat!
16:37 < djph> linux-vdso.so.1 is at memory location (whatever)
16:38 < djph> libc.so.6 is /lib/x86_64[...] and at memory location (whatever)
16:38 < djph> same for the last one
16:38 < Richard_Cavell> okay so my code uses 3 libraries, is that correct?
16:38 < ayecee> Richard_Cavell: yes
16:38 < ayecee> three that are dynamically linked anyways
16:39 < Richard_Cavell> You can see how simple it is. Should I be bothered that it uses 3 libraries, or is that just normal?
16:39 < ayecee> that's normal
16:39 < Richard_Cavell> okay
16:39 < Richard_Cavell> And the fact that they have memory locations, does that mean that they were already loaded when I ran ldd, or that they have been loaded for the purpose of ldd, or what?
16:40 < djph> that's normal.  first is linux headers, second is the standard C library, third is I forget what.  These three get pulled in *every* time you compile a C program
16:40 < ayecee> they were loaded when ldd ran the executable
16:40 < ayecee> third is the dynamic library loader
16:40 < ayecee> first isn't "headers"
16:40 < ayecee> though i don't know offhand what that is.
16:41 < djph> they're pointing to memory locations, because they're "shared objects" -- that is, they're dynamically called, rather than being compiled directly into the program you wrote.
16:41 < djph> ayecee: dammit ...
16:41 < Psi-Jack> ayecee: What about onhand?
16:41 < ayecee> i have the manpages onhand
16:41 < ayecee> i guess i could hunt through those.
16:41 < Psi-Jack> hehe
16:41 < djph>        vdso - overview of the virtual ELF dynamic shared object
16:42 < ayecee> something to do with making system calls faster, looks like
16:42 < djph> yup
16:43 < Richard_Cavell> So when I run ldd, it actually runs the program, and the program then loads up those 3 libraries?
16:43 < djph> no
16:43 < ayecee> yes
16:44 < djph> wait what?
16:44 < ayecee> now you know
16:44 < prussian> ldd will indeed execute code
16:44 < djph> hm, it appears I've misunderstood the manpage then
16:45 < prussian> that's why I prefer objdump if possible
16:45 < ayecee> i know, it's kind of surprising :)
16:45 < djph> not really no, manpages suck sometimes. :)
16:45 < puff> monkeyisl: Re: ln, sort of but not at the technical level.
16:45 < Richard_Cavell> So the second one is "the standard library". Does that mean that the entire C standard library is one binary chunk called libc.so.6?
16:46 < puff> monkeyisl: In windows, if I recall correctly, a shortcut is a file that contains several settings, one of which is the location of the executable file that you actually want to run.
16:46 < djph> I had interpreted it as "ldd /some/executable" just inspected the executable, and didn't actually *run* it.
16:46 < ayecee> yeah, that's the surprising part
16:47 < djph> ... oh ... it's hidden in another manpage ... ld.so(8)
16:47 < djph> errr LDCONFIG(8)
16:48 < djph> whatever ... I'm too tired after dealing with bang..where-ever to think straight
16:48 < puff> monkeyisl: In linux, the ln command is used to create a "link" to a file.  In a limited sense, a link is similar to a windows shortcut in that it contains the location of another file.  But how links are implemented at the very low level is a bit different.
16:49 < puff> monkeyisl: https://www.linux.com/learn/intro-to-linux/2017/6/understanding-linux-links
16:50 < gump> anyone else notice that NPM in CentOS 6 stopped working on friday?
16:51 < prussian> i iamgine all of node ecosystem in centos6 should stop working
16:51 < oiaohm> puff: monkeyisl   https://developer.gnome.org/desktop-entry-spec/  shortcut file on windows the closest on Linux is a .desktop file.
16:51 < prussian> get the latest nodejs stable release from some scl or external sources
16:52 < gump> prussian: yeah the official node repos still work fine
16:58 < Polyonymous> I'm looking to throw a linux (CentOS) install on my local server. I'd like to use a pair of old laptop HDDs in such a way that, when one of them dies, I can simply slot in yet another old laptop HDD and have everything chug along happily. With minimal effort on my part. Although this seems like an obvious case for a software RAID1, I've not tinkered with it in years and don't know if there's a good way to configure booting in this
16:58 < Polyonymous> Is there a clever way to boot from mirror raids nicely? (Preferably something I wouldn't have to sit down and re-jigger every time something broke.) Am I better off digging up an old RAID controller and booting through that? Would using a RAID controller make it unfeasable to boot from either drive (degraded, obviously) should the controller fail?
17:01 < ananke> Polyonymous: what happens is that you have raid1 for your boot filesystem, and the computer boots from one of the sides. after linux is booted, it assembles a raid1 array
17:01 < ananke> Polyonymous: there are plenty of guides out there showing how to do it
17:02 < Polyonymous> Aye, I've found guides on how. I'm trying to learn about the failure modes before I put the whole mess together.
17:03 < Psi-Jack> Heh, the deeper I dig in, the more curious I get. The original author of Grav CMS is actually the co-founder of Joomla. A former Drupal core dev left Drupal and is now working with Grav. Iiiiinteresting. :)
17:04 < Polyonymous> More clearly stated: my question is if there is a 'best practise' implementation. For example, would an older, wiser user just back up key files and lose less time to tinkering?
17:05 < Psi-Jack> Always backup.
17:05 < Polyonymous> Always do
17:06 < Polyonymous> But off-site backups are for when the entire box melts into slag, I'm curious about the 'get it back online with little effort because one of the HDDs decided to release the magic smoke' case
17:09 < ayecee> Polyonymous: grub can boot from raid, though you'd want to install the bootloader on each of the disks in the boot raid set.
17:10 < ayecee> raid1 at least, not 100% sure about raid5/6
17:10 < Polyonymous> Just raid1
17:10 < Polyonymous> And great.
17:10 < JimBuntu> Polyonymous, Then RAID is your friend. RAID1/5
17:10 < ayecee> raid can be a fickle friend
17:10 < Polyonymous> Aye. I tend to be a bit paranoid about backups, so it's allowed to be fickle
17:11 < Polyonymous> And I've found raid1 to be much better behaved, historically >.>
17:11 < fendur> ayecee: fickle how?
17:11 < fendur> you can just point to an article/blog
17:11 < azarus> as I understand, mt76 supports this wifi card: https://v.gd/M4rO7O
17:11 < Polyonymous> Anyway. Thanks for sanity checking me
17:12 < ayecee> fendur: fickle in that if you don't set it up right, it don't work right.
17:12 < ayecee> like, if you install the bootloader on one disk but not the other.
17:12 < azarus> but in my distro I don't see a mt76.ko? CONFIG_WLAN_VENDOR_MEDIATEK=y is there... :s
17:14 < the_drow_> I'm trying to mount an ntfs volume with udev. I'm getting Transport endpoint is not connected
17:14 < the_drow_> From my research on the internet it seems like it's not possible to mount a ntfs usb volume with udev
17:14 < the_drow_> I'd rather not walk away from my implementation and move to udisks2 if possible
17:15 < the_drow_> Is there a way around it?
17:15 < ayecee> the_drow_: that doesn't sound like a message related to ntfs. how are you mounting it?
17:15 < ayecee> also, does your research say why that's the case?
17:15 < the_drow_> ayecee, '/bin/mount -t ntfs-3g -o gid=100,dmask=000,fmask=111,utf8,flush,rw,noatime,users /dev/sdc1 '/media/flash_drive_sdc1''
17:16 < the_drow_> no, the debian mailing lists says just because
17:16 < the_drow_> ayecee, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774149;msg=59
17:16 < ayecee> weird. that sounds more like a samba or nfs error.
17:16 < ayecee> oh, usb transport.
17:17 < ayecee> huh. i don't have any ideas, but i appreciate the problem.
17:18 < the_drow_> mounting manually works just fine
17:25 < Psi-Jack> oh good, the cafe has arrived with coffee? ;)
17:26 < Pentode> coffee? where?
17:26 < absurdistani> COFFEE!
17:26  * Pentode looks around frantically
17:32 < Psi-Jack> Well, now I have my name in Grav's code history. Muahaha.
17:32 < edge_hay> Hi
17:33 < edge_hay> So I'm coming from ##windows…
17:33 < edge_hay> They didn't like me mentioning that I was running a stable os
17:34 < edge_hay> Hope you guys don't mind
17:34 < fendur> I also think stable OSs are stupid.
17:34 < edge_hay> You mean any os apart from windows?
17:35 < fendur> just stable OSs
17:35 < edge_hay> You're in a linux chan :/
17:35 < fendur> and?
17:35 < edge_hay> What os are you running?
17:35 < fendur> fendos. It's terrible.
17:35 < edge_hay> System Information: Model: MacBook Pro (13-inch, Retina, Late 2013) • OS: macOS High Sierra (Version 10.13.4, Build 17E199)
17:35 < edge_hay> It's terrible too
17:36 < edge_hay> Kernel panic per year: 0.02
17:37 < edge_hay> s/0.02/0.2/r That's one every 5 years for me.
17:37 < zaruba> I just downloaded the latest firefox, now I'd like to create a launcher for it but I'm not sure how to do that. Anyone?
17:37 < edge_hay> A launcher?
17:38 < edge_hay> What do you mean by that? D:
17:38 < revel> https://frugalfun4boys.com/2013/06/06/how-to-build-a-catapult-out-of-dowel-rods-and-rubber-bands/
17:39 < edge_hay> Still more stable than windows
17:39 < zaruba> a shortcut link to open that application, edge_hay
17:39 < revel> zaruba: So, a .desktop file?
17:39 < edge_hay> what distro?
17:39 < zaruba> yes
17:39 < zaruba> debian
17:39 < edge_hay> Oh. Never ran debian with a gui :/
17:39 < revel> .desktop files are sort of universal.
17:40 < the_drow_> ayecee, Well, udisksctl mount works. I just had to sed into fstab for it :(
17:40 < edge_hay> revel is it like a .bash_profile file?
17:40 < mnemon> zaruba: https://wiki.archlinux.org/index.php/desktop_entries has some example files
17:40 < revel> ^
17:41 < revel> edge_hay: No, it's like... Well, you can have a specific image, process, description etc. tied together so you can use them as desktop shortcuts or in menus or whatever.
17:42 < revel> /usr/share/applications/ contains a ton of 'em.
17:42 < revel> (don't stick your own there)
17:43 < edge_hay> I don't have /applications folder on macos
17:44 < delt> Hello
17:44 < Richard_Cavell> So may I ask about libraries again?  This file libc.so.6 - does the so stand for anything?
17:44 < delt> what's the name of the utility to draw directly on the root window?
17:44 < revel> Richard_Cavell: Shared object.
17:44 < revel> edge_hay: I doubt .desktop files are a thing on MacOS.
17:44 < Richard_Cavell> revel, ok thanks.  And what does the number 6 mean in libc.so.6 ?
17:44 < delt> draw text i mean
17:45 < JimBuntu> revel, macOS has an equiv
17:45 < mnemon> Richard_Cavell: shared object or something like that iirc? denotes shared libs
17:45 < revel> Some sort of version, probably.
17:45 < revel> JimBuntu: So does Windows, but it's not the same.
17:45 < edge_hay> revel that's my /usr/share/ https://pastebin.com/PxhGbkc3
17:45 < JimBuntu> revel, in macOS, they are .command files. I can't remember if you can assign icon/etc.
17:46 < revel> edge_hay: If you really are on MacOS, then having .desktop files would be pointless.
17:46 < Richard_Cavell> So on my machine my libc.so.6 file is a link to another file that is 1.8 megabytes. Am I to take it that this 1.8 megabytes implements the whole of the standard C library?
17:47 < edge_hay> oh
17:47 < revel> 1.9 megabytes for me :D
17:48 < azarus> When was the mt76 driver introduced?
17:48 < revel> Richard_Cavell: Yes.
17:48 < ayecee> Richard_Cavell: sounds reasonable
17:48 < edge_hay> :D
17:48 < edge_hay> C OP
17:48 < Richard_Cavell> Now, I'm assuming that many programs on my machine use the C standard library. Is this library always loaded into RAM?
17:49 < djph> Richard_Cavell: for some values of "always"
17:49 < edge_hay> Your kernel most likely is made in C Richard_Cavell
17:49 < jelly> Richard_Cavell: most of it, some stuff is separate (floating point is in libm.so*, some localization stuff is in libintl.so*)
17:49 < revel> edge_hay: It's a "freestanding" binary that doesn't have a C library.
17:49 < ayecee> Richard_Cavell: pretty much, yeah
17:50 < mices> no matter how many drives in a raid array i only need one for parity to be able to protect against data loss if a drive in the array fails?
17:50 < djph> mices: no
17:50 < ayecee> mices: yes
17:50 < revel> Richard_Cavell: I don't think every memory gets its own libc loaded into memory, but it's there.
17:50 < revel> s/memory/process/
17:50 < edge_hay> revel doesn't mean that the binary doesn't contain library functions :/ I think they do
17:51 < edge_hay> s/they do/it does/r
17:51 < ayecee> mices: however, that would only address a single disk failure scenario.
17:51 < mices> ayecee: i'm thinking about building a raid array from usb sticks
17:51 < ayecee> neat
17:51 < edge_hay> It's so nice to see people use regex in irc :D
17:51 < mices> does anything else make sense comparitively
17:51 < edge_hay> ttyX D:
17:51 < edge_hay> nuuuh
17:51 < edge_hay> who
17:52 < ayecee> mices: sounds like a fun experiment, but doesn't sounds practically useful.
17:52 < ayecee> i couldn't immediately say why though.
17:52 < revel> edge_hay: The kernel? Well, uhh, I'm not a professional on the topic.
17:52 < mices> ayecee: and  i backup to what then?
17:53 < ayecee> mices: what do you back up to now?
17:53 < revel> edge_hay: But no, kernels can't depend on libraries.
17:53 < mices> another usb stick array?
17:53 < edge_hay> Yeah neither am I but functions like malloc are implementation defined so they must be defined
17:53 < mices> if my data was on a usb stick array
17:53 < ayecee> it's usb stick arrays all the way down.
17:53 < mices> i'd backup to another usb stick array
17:53 < edge_hay> yeah I guess it's not using libc
17:53 < djph> revel: I believe that the kernel, if compiled from source, uses internal static links to the C libraries that it needs, as opposed to dynamic links via libc.so.X
17:53 < fendur> mices: I have done this, and I use it regularly to back up work files on my work machine. I assume it's safer than using one thumb drive.
17:54 < revel> I meant dynamic libraries, yeah.
17:54 < djph> s/if compiled/when compiled/
17:54 < edge_hay> eitherway 1.8Mb in memory isn't much
17:54 < mices> what's a better way to format usb sticks with gpt or msdos partition tables
17:54 < djph> not at all
17:54 < absurdistani> revel: the kernel has its own C lib. from there, if you are using dynamic linking, then you likely have C lib loaded in RAM. if you are using some distro like Stali, then no.
17:54 < mices> to do this use gpt?
17:54 < revel> Since it's just standing on top of the hardware on its own with nothing there to manage memory or handle filesystems for it.
17:55 < absurdistani> mices: I prefer to use MBR on USB sticks. Makes them more portable.
17:55 < BCMM> mices: as long as the USB stick doesn't need to be bootable, it's quite possible to put the filesystem on the whole block device
17:55 < BCMM> i.e. with no partition table at all
17:55 < BCMM> (and yes, windows supports that)
17:56 < absurdistani> BCMM: some version of macOS freak out if you do that
17:56 < BCMM> huh, didn't know that
17:56 < fendur> mices: mine is built on a raspberry pi zero (W), so it effectively acts as a portable, potentially batter powered NAS.
17:56 < BCMM> it used to be relatively common to get USB sticks like that out of the box
17:56 < absurdistani> BCMM: i discovered this in a very inconvenient way :(
17:56 < Trel> When SSH'd into a machine using a key, is there a way to see WHICH key in the authorized_keys file I'm using?
17:57 < BCMM> Trel: ssh -v
17:57 < edge_hay> If it's compatible with windows it works on macos
17:57 < BCMM> Trel: it will tell you all about which keys its offering and which one is accepted
17:57 < mices> fender: you're using a powered hub?
17:57 < mices> fendur ^
17:57 < Trel> BCMM: that just prints the hel
17:57 < fendur> mices: no, it's passive
17:57 < Trel> *help
17:58 < BCMM> Trel: i mean, add the -v option to your existing ssh command line
17:58 < fendur> er, whatever they call not-powered usb hubs.
17:58 < mices> fendur: i'm looking at hubs like this on ebay https://www.ebay.com/itm/7-Port-USB-2-0-Multi-Charger-Hub-High-Speed-Adapter-ON-OFF-Switch-Laptop-PC-US/382164931804?hash=item58face14dc:g:760AAOSwhilZaT67
17:58 < BCMM> Trel: ssh -v user@host
17:58 < edge_hay> so just make it compatible with Windows and Apple will do the rest. Unless it's ntfs. In which case god bless your soul
17:58 < Trel> BCMM: I'm connecting with Putty, I need to see which in the remote machine
17:58 < BCMM> oh, no idea
17:58 < djph> Trel: you don't see "in the remote machine" -- the remote only holds PUBLIC keys.
17:58 < repys> I had a RAID1 in my computer and suddenly I got that the system didn't start anymore. at the boot it didn't find the efi boot file from both disks. few hours before I changed power supply of my computer, I am not sure if that would be related to. but my question is, I can't see any bad sector from smartctl from both disks. 1. what could be it happe
17:58 < repys> ns to these disks? 2. can smartctl see if there problems in the first sectors of the disk (where efi files are)?
17:59 < BCMM> Trel: might be logged by sshd, depending on the settings. are you root?
17:59 < djph> you're presenting the remote with a private key, and it's comparing a sig against the public keys it knows are authorized.
17:59 < Trel> djph: I'm trying to see on the remote machine, which pubkey in authorized_keys is being matched for the connected session
17:59 < BCMM> djph: he asked "which key in the authorized_keys file"
17:59 < Trel> BCMM: I have sudo access, but I'm not SSHing to root
17:59 < BCMM> djph: so i don't see a reason to think he doesn't know that
18:00 < djph> BCMM: all kinds come to all places :|
18:00 < edge_hay> mices: https://www.amazon.com/gp/product/B01N9M32TA/ref=od_aui_detailpages00?ie=UTF8&psc=1 I bought that, works great… No idea about having 7 usb ports tho
18:00 < BCMM> Trel: hang on, putty doesn't let you offer multiple keys anyway, does it?
18:00 < repys> any idea guys? :)
18:00 < BCMM> Trel: you're using whichever key putty is configured to use, surely?
18:00 < ayecee> several ideas!
18:00 < ayecee> just not about your thing
18:01 < edge_hay> Probably the best usb hub I've ever bought. All the ports support charging. The cable is thick (that's what she said) and the speed is the same
18:01 < fendur> mices: mine is only 2 drives. But if you're thinking of many drives, yeah powered might help.
18:01 < djph> Trel: perhaps state the problem / query in a different manner?
18:01 < absurdistani> repys: boot to a livecd and then do: mdadm --assemble --scan
18:01 < absurdistani> repys: note the disk names
18:02 < absurdistani> repys: then you can do like: mdadm --detail --scan >> /mnt/targetAssembledArray/etc/mdadm.conf
18:02 < repys> absurdistani: yes I can mount the disk but of course I can't boot anymore the computer from these disks because I get that efi boot files are not found
18:02 < absurdistani> repys: ah okay
18:02 < edge_hay> Trel `whoami` ?
18:02 < repys> absurdistani: smartctl doesn't show any bad sector but something is happened :(
18:02 < repys> absurdistani: so I wanted to know how can I check the real state of these disks?
18:03 < Trel> BCMM and djph, I know my private key though it's in putty's ppk format.  I want ot know WHICH line in authorized_keys I would need to delete, to make it so the key I'm currently connected with will no longer work.  I have five separate lines. I do not know which pubkey corresponds to the private key I'm currently using.
18:03 < noway96> I have three USBs flashed with same software. Two of them booted successfully. One of them 'mounting /dev/loop0 failed invalid argument'. I then copied the rootfs over to the failing drive and it booted. Does that mean that the USB wasn't ejected properly before which was causing the issue?
18:03 < BCMM> Trel: to confirm, you don't have the public key half in putty?
18:03 < absurdistani> repys: so in that case, try something like... chroot to that mounted location, then try: efibootmgr -c -d /dev/sda -p 1 -l '\efi\kernelNameHere' -L "your linux system" -u "root=/dev/sda2 nomodeset intel_iommu=on" or whatever
18:04 < BCMM> Trel: doesn't a .ppk  file contain both halves of the key together?
18:04 < absurdistani> sounds like the efi entry got dead, so you just need to recreate it
18:04 < mnemon> Trel: you can get the public key from the private key via putty-gen or ssh-keygen
18:04 < mnemon> then just remove the matching line
18:05 < repys> I tried to boot another computer with these disks and I get the same error
18:05 < djph> or remove 'em all ... granted that may have the side effect of "nothing works" :)
18:06 < rocketmagnet> hi all, does someone know if there is an opensource calculator for linux where i can write my formulars with my hand ?
18:06 < rocketmagnet> i found many great calculators but i'm always missing this feature
18:06 < ayecee> like with a pen?
18:06 < rocketmagnet> yes
18:06 < rocketmagnet> i've a touchscreen
18:06 < Trel> Guys, what I have access to right now is authorized_hosts on the remote machine, and the currently connected putty session.  The key is loaded into the agent, so I don't currently have access to the file itself or I could just convert it to a SSH key and then use ssh-keygen -y to get the pubkey.
18:06 < ayecee> i'm virtually certain that there isn't.
18:07 < BCMM> Trel: sorry, what precisely do you mean by "the key is loaded into the agent"?
18:07 < rocketmagnet> but i'm sure there are such calculators around
18:07 < BCMM> what agent, on which machine?
18:07 < ayecee> me, i'm sure there isn't.
18:07 < rocketmagnet> :(

18:08 < noway96> How do you debug initscripts?
18:08 < noway96> also asking, how do you write initscripts
18:08 < noway96> are they just a bunch of bash?
18:08 < ayecee> start at the first line, and go from there
18:08 < revel> I use nano :D
18:08 < ayecee> they are just a bunch of bash, usually
18:09 < noway96> But I suppose with limited commands in bin?
18:09 < ayecee> they don't have to be, but they usually are
18:09 < ayecee> noway96: nope, though you may have to set up your own path
18:09 < revel> Or use absolute paths.
18:09 < BCMM> Trel: one option is to increase the logging level on sshd
18:10 < noway96> K.
18:10 < BCMM> at LogLevel VERBOSE it will give fingerprints of keys used
18:10 < Trel> BCMM: on the machine I'm using pagent is running with the private key loaded in (to which I no longer have access).  I'm connected to the remote server, to which I have access to authorized_hosts.  I want to remove the line that allows the key I'm currently connected with to ensure it cannot be used again.  I don't want to remove any other key.
18:10 < BCMM> Trel: right, but you can reconnect putty?
18:10 < BCMM> Trel: increase loglevel on sshd, restart sshd, reconnect
18:11 < BCMM> Trel: the log will show the fingerprint of the key used
18:11 < Trel> Does it output to a specific log file or the general syslog? Right now I don't seem to have any ssh related log files in /var/log
18:11 < mnemon> Trel: Is it not visible in pageant? also if the ssh-agent forwarding is on you can just ssh-add -L in the session to show the loaded keys.
18:12 < Trel> mnemon: pagent shows what appears to be the fingerprint, not the the actual pubkey, I don't see anything corresponding in authorized_keys.  Let me check the output of that command though
18:12 < Trel> Nope, not on
18:13 < rocketmagnet> ayecee: i found something: https://stackoverflow.com/questions/3570220/ocr-lib-for-math-formulas
18:13 < BCMM> Trel: general log, unless you tell sshd otherwise. i think.

18:16 < kcrowboat> I got the beat !!!!
18:16 < mnemon> Trel: ssh-keygen -lv -E md5 -f .ssh/authorized_keys will get the fingerprints
18:17 < mnemon> or -E sha256 ... but I think pageant still shows md5?
18:18 < Trel> mnemon: that got it, I see which line matches from the fingerprint (it's md5)
18:18 < Trel> thanks!
18:18 < mnemon> np
18:19 < Trel> in authorized_keys, the last 'field' is a comment?
18:20 < ayecee> kind of, yes
18:20 < Trel> I'm labeling the remaining ones to ensure I don't run into this again.
18:20 < ayecee> it's part of the key, but it's a comment within the key
18:21 < Trel> I can modify the key as well right?
18:21 < Trel> For now I'm storing the label in a separate file to reference
18:21 < ayecee> using ssh-keygen, yes
18:22 < Trel> Cool, thanks.
18:23 < Trel> Thanks everyone for the help
18:23 < prussian> you can add environment=gibberish=key_ident as well or use an AuthorizedKeysCommand
18:31 < TyrfingMjolnir> prussian: Where are you from?
18:35 < Richard_Cavell> another newb question: In /proc/cpuinfo I have a whole lot of information. Is this information just a text file, or is it somehow generated when I type cat /proc/cpuinfo ?
18:35 < BCMM> Richard_Cavell: it's not a "real" file, in that it's not actually on the disk somewhere
18:36 < BCMM> Richard_Cavell: what's happening is that there is a special psuedo filesystem mounted at /proc/
18:36 < Richard_Cavell> ok
18:36 < BCMM> the contents of which is generated on the fly by the kernel
18:36 < Richard_Cavell> Is there anything else in /proc that I might find interesting?
18:36 < lupine> everything, more or less
18:36 < BCMM> Richard_Cavell: yes! those numbered directories inside proc correspond to currently running processes
18:37 < BCMM> Richard_Cavell: each directory name is the PID of a process
18:37 < lupine> consider /proc/meminfo
18:37 < revel> Plus mount info.
18:37 < revel> And info on memory usage.
18:37 < revel> And some kernel stuff.
18:38 < BCMM> Richard_Cavell: for example, you can look at /proc/[some number]/cmdline to get the command that was used to start a given process
18:38 < revel> Or /proc/cmdline for the kernle cmdline :D
18:38 < revel> s/nle/nel/
18:39 < revel> And /proc/version is a bit more informative than `uname -a`

18:50 < RonWhoCares> I have an rsync question https://askubuntu.com/q/1021667/453336
18:51 < MrBech^imac> I think this is the right channel to ask, but don't crucify me if it's not. I'm having a issue where I can't connect to mysql with "localhost", but "127.0.0.1" works fine. I now know it's the permissions on the /var/lib/mysql/mysql.sock file that is wrong. The permission is: "srwxrwxr-x" and should be "srwxrwxrwx". What causes this problem I do not know. Would someone care to investigate with me and figure this one out? Thanks.
18:51 < ayecee> RonWhoCares: hopefully the forum members can help you with that.
18:51 < ananke> RonWhoCares: you should look into using ssh keys instead of supplying password on command line like that
18:52 < djph> MrBech^imac: it's probably a user permission (in mysql) rather than file permission issue...
18:52 < RonWhoCares> ananke:  The reason I pasted the link is because it is too much to paste here
18:52 < MrBech^imac> @djph Let's check. Could you guide me through it?
18:53 < ananke> MrBech^imac: define 'can't'
18:53 < RonWhoCares> ananke: I started with ssh keys.  The cron job doesn't have acess to the key
18:54 < MrBech^imac> @ananke Making a PDO connection in PHP, using "host=localhost" I get permission denied. When using "host=127.0.0.1" there is no problem.
18:54 < mawk> that's a classic MrBech^imac 3~
18:54 < mawk> just use 127.0.0.1
18:54 < ananke> MrBech^imac: check how your access control is set up in mysql
18:54 < mawk> localhost will get through the unix socket
18:54 < djph> MrBech^imac: look at whether or not user@localhost is allowed.
18:55 < MrBech^imac> @mawk What's that mawk?
18:55 < mawk> if some special plugin is enabled
18:55 < mawk> and it is by default with mariadb
18:55 < MrBech^imac> I'm running mariadb
18:56 < mawk> it's some means of communication that uses endpoints living on the filesystem
18:56 < MrBech^imac> So is this something I should fix? or just use 127.0.0.1?
18:56 < mawk> it's not a bug
18:56 < MrBech^imac> I read somewhere that using "localhost" would be "faster"
18:56 < mawk> it's for instance to allow root to use mysql without logging in
18:56 < mawk> mariadb will detect root is on the other side using properties of unix sockets
18:56 < mawk> it uses the unix socket instead of a TCP socket, it's maybe faster but you don't need that
18:57 < SCHAPiE> 127.0.0.1 is the real IPv4 localhost; the name 'localhost' is just a local name bound to that IP.
18:57 < MrBech^imac> Why won't I need "faster"?
18:57 < Celmor> I want to use gzip to compress a log file while it is being written (long-running process in background) but it seems it won't 'flush' content to file till process exits so I guess gzip keeps allocating more memory the more I write and if PC hangs it won't write at all?
18:57 < SCHAPiE> So 127.0.0.1 is technically faster, because it saves a lookup, even locally
18:57 < solidfox> what database do you guys prefer the most?
18:57 < ananke> solidfox: depends on the purpose
18:57 < SCHAPiE> solidfox: postgresql
18:57 < MrBech^imac> @SCHAPiE Hm. I read the opposite. that localhost was faster. But ok
18:57 < MrBech^imac> Thanks for clarifying @mawk. I will forget about it, and just use 127.0.0.1
18:58 < uplime> MrBech^imac: who told you that?
18:58 < ananke> MrBech^imac: and you never even bothered to check how your user permissions are set in your database
18:58 < SCHAPiE> the difference should be negligeable, or maybe not even noticeable
18:58 < MrBech^imac> @uplime I read it somewhere.... That browser tab has since been closed :)
18:58 < SCHAPiE> MrBech^imac: Firefox has a "Undo Closed Tab" function, Ctrl Shift t
18:58 < uplime> i wouldn't believe that site then :)
18:58 < mawk> SCHAPiE: here localhost makes it travel through the unix socket, if the relvant plugin is enabled
18:58 < mawk> that's the faster we're talking about
18:58 < MrBech^imac> @ananke I have checked them before. They are as they should be.
18:59 < uplime> also its not necessary to prefix user names with @
18:59 < SCHAPiE> mawk: ah, okay, a socket is something completely different
18:59 < ananke> MrBech^imac: which is? you never provided that info
18:59 < MrBech^imac> @SCHAPiE Sorry, it's 100 closed tabs since
18:59 < mawk> MrBech^imac: you don't need faster because it's already fast enough
18:59 < SCHAPiE> MrBech^imac: it keeps a chronological history of closed tabs, not sure how many though :p
18:59 < za1b1tsu> I see online that people save their configuration files in github, nicely organized, but configs are usually split all other the place. How do they do it?
19:00 < uplime> za1b1tsu: symbolic links
19:00 < SCHAPiE> mawk: you could argue that using a socket implies filesystem access as well, which might make it slower
19:00 < uplime> ie, ~/.bashrc is a symbolic link to ~/dotfiles/.bashrc
19:00 < SCHAPiE> depending on the storage
19:00 < mawk> that's just constant time complexity SCHAPiE
19:00 < uplime> at least, thats how I do it
19:00 < mawk> setup times and stuff
19:01 < mawk> you need to measure the variable part
19:01 < SCHAPiE> hmkay, makes sense
19:01 < mawk> and for the variable part I guess the unix socket is faster, but it's just a guess
19:01 < za1b1tsu> uplime, that's interesting and they make a script to link everything toghether?
19:01 < mawk> the canonical idea is to take a very large data string, and measure transmission time
19:01 < uplime> za1b1tsu: what do you mean link everything together?
19:02 < mawk> the larger it is, the less important that constant part of complexity is
19:02 < AnAverageHuman> za1b1tsu: stow is a symlink "manager" if you're looking for programs.
19:02 < za1b1tsu> like I have to link tmux, vim, etc. I create a script to link everything when I'm on a new pc
19:03 < za1b1tsu> AnAverageHuman, is it needed though? Maybe if I want to remove them
19:03 < BCMM> well, most things will be in ~/ or ~/.config/
19:03 < BCMM> so you could probably just do a couple of ln -s * ../ sorta things
19:04 < autopsy> BCMM, what about system wide configs don't they get copied to home directory too?
19:04 < autopsy> BCMM, that would imply read access on configs for the root filesystem.
19:04 < autopsy> By all or other.
19:07 < uplime> za1b1tsu: i guess. I just do it by hand
19:07 < uplime> it doesn't take very long
19:07 < uplime> or write a short loop in bash to do it for me
19:08 < edge_hay> uplime "I just do it by hand"
19:08 < edge_hay> So do I. Smh
19:09 < uplime> something like `for file in ~/.{bash,vim,nano}rc; do ln -fs "dotfiles/$file" "$file"; done`
19:09 < ancient_dog> should I use systemd or openrc when installing a new distro?
19:09 < edge_hay> imma pretend you pretended to laugh so I can feel better about myself
19:09 < edge_hay> :)
19:10 < edge_hay> eheh
19:10 < uplime> i didn't
19:10 < edge_hay> Lame
19:10 < autopsy> ancient_dog, systemd is way better I've read.
19:10 < za1b1tsu> uplime, thank you
19:11 < uplime> np
19:13 < edge_hay> I'm trying to find a way to stay on topic while telling uplime I don't like them. I wonder how I can do that in a bash script
19:14 < edge_hay> echo 'uplime: I don't like you'
19:14 < edge_hay> Never mind I found how to do it.
19:14 < sauvin> It would be nice if you'd find some *other* channel to do that kind of thing in, though.
19:15 < edge_hay> sauvin may I pm you? Because I actually don't want to get banned from this chan
19:15 < sauvin> We can talk about it in ##linux-ops, if you want.
19:18 < mawk> can a process in a sandbox attack me by stealing all the data from /dev/random or /dev/urandom ?
19:18 < mawk> like by doing it when the system is generating a private key
19:22 < spammcoin> they could bring /dev/random to a crawl  urandom doesn't seem affected through /proc/sys/kernel/random/entropy_avail
19:22 < AnAverageHuman> mawk: /dev/random blocks until it has enough entropy to continue. So your key might take longer than usual to create, but should still be secure.
19:23 < mawk> I see
19:23 < Dagmar> That's because you should use /dev/urandom.
19:24 < mawk> so no need to limit the read speed from /dev/random
19:24 < mawk> no security need at least
19:24 < mawk> if I wanted to apply a limit, what would be a sane value ?
19:24 < uplime> who even needs security?
19:24 < Dagmar> Anyone who actually has a problem with /dev/random blocking should use /dev/urandom, because clearly you don't know enough to know why it's perfectly okay that /dev/random blocks, and why it's perfectly reasonable to use the random data from /dev/urandom in pretty much _all_ cases
19:24 < JimBuntu> "security" -> That feeling when you don't who what you don't know.
19:25 < uplime> when you don't who?
19:25 < spammcoin> make an entropy namespace
19:25 < JimBuntu> s/who/know
19:25 < mawk> that doesn't exist spammcoin
19:25 < mawk> yet

19:28 < sauvin> I've never met a hot pocket I didn't like.
19:28 < uplime> exactly
19:28 < sauvin> NOM
19:28 < edge_hay> uplime please turn off your Pedantic Lock. On your keyboard look for your brain. You must have left it somewhere.

19:29 < sauvin> edge_hay, that's not the kind of comment we generally regard as helping maintain and promote a civil atmosphere.
19:29 < ayecee> it's not even funny
19:29 < sauvin> That one about the "pedantic lock".
19:29 < ayecee> it should be at least one of the two
19:30 < mawk> why are you attacking him edge_hay
19:30 < mawk> you have something you need to compense for ?
19:30 < ayecee> says the white knight
19:30 < edge_hay> mawk lets take that to pm if you want to know
19:30 < mawk> lol
19:30 < autopsy> Wow you guys are on one.
19:31 < sauvin> We're all on something, that seems clear. Not too sure where these mushrooms came from.
19:31 < uplime> those were some funny tasting brownies
19:31 < fendur> I just ate a four leaf clover. Will that do anything?
19:31 < sauvin> Expect gastrointestinal irritation and possibly some fever.
19:31 < edge_hay> good luck with that
19:32 < fr0xk> Stop it, I am hungry already!
19:32 < uplime> yeah but it will be a lucky fever
19:32 < edge_hay> ah
19:32 < fendur> uplime:  :>
19:32 < compdoc> I think clover.is poisonous unless youre a rabbit
19:32 < fendur> compdoc: then we're good!
19:32 < edge_hay> Isn't it the other way around? D:
19:32  * sauvin wikis
19:33 < uplime> rabbits are poisonous to clovers?
19:33 < compdoc> but also think youd have to eat more than one to harm yourself
19:33 < edge_hay> Yes uplime
19:33 < edge_hay> That's clearly what I meant
19:33 < BustyLoli-Chan> How hard is it to run windows games on linux in the present day?
19:33 < edge_hay> apt-get wine?
19:33 < fendur> BustyLoli-Chan: much easier than going back in time/to the future to do it!
19:33 < autopsy> BustyLoli-Chan, winehq says Tom Clancy Ghost Recon 2 has a platinum rating.
19:33 < emberquill> Depends on the game, to be honest. Lots of games run well in Wine, lots don't.
19:33 < fendur> sorry. It's the 4LC talking.
19:34 < BustyLoli-Chan> or.. is there a variant of linux that is extremely good at running windows VMs alongside a linux machine.
19:34 < fr0xk> BustyLoli-Chan: I guess its very easy, just click that the autorun.exe and the game will run at 300FPS? I think
19:34 < fr0xk> :)
19:34 < autopsy> BustyLoli-Chan, I think you can get VirtualBox which is pretty good i've read.
19:34 < uplime> last time I used a linux desktop it was a pain
19:34 < BustyLoli-Chan> I always want to switch to linux, and I like using it, but I always hate that there are limited gaming options or some new game my friends will play comes out and then I can't play it
19:34 < uplime> but that was years ago
19:34 < emberquill> I'd say check winehq to see if the game works well in Wine. If not, you can run it in a VM but for graphics-intensive games you'll definitely need to do GPU passthrough of some kind.
19:34 < solidfox> I just remmebered that the reason I stopped using xfce (on xubuntu) was because I don't like that all the windows appear in the exact middle of the screen
19:34  * sauvin runs across a reference to clover honey but not finding anything on clover toxicity
19:35 < solidfox> I wonder if there was some other issue I'm forgetting
19:35 < fr0xk> I am not sure if COD Ghost is in steam
19:35 < fendur> BustyLoli-Chan: Dual boot?
19:35 < edge_hay> I don't really like virtual box :/ I have it installed and it seems to have some input delay for some reasons
19:35 < edge_hay> I do have a bad setup tho
19:35 < edge_hay> System Information: Model: MacBook Pro (13-inch, Retina, Late 2013) • OS: macOS High Sierra (Version 10.13.4, Build 17E199)
19:35 < BustyLoli-Chan> fendur it's always an option... but it's like even more of a pain to switch OS entirely
19:36 < fendur> BustyLoli-Chan: I don't follow "more of a pain" to dual boot? Or to single boot linux?
19:36 < edge_hay> It doesn't show but that's an intel i5 and 8gb of ram :/
19:36 < BustyLoli-Chan> more of a pain to dual boot
19:36 < edge_hay> Agree with that
19:36 < autopsy> edge_hay, that is exactly what I have too on a laptop.
19:36 < edge_hay> autopsy :c
19:36 < fendur> BustyLoli-Chan: Now I really don't follow. How's that a pain? Unless splitting HD resources is problematic.
19:37 < emberquill> Honestly, just having to use Windows is a pain lol. I wouldn't mind dual booting if my Windows installation booted as fast as my Linux one.
19:37 < edge_hay> wine works great tho but I need windows for class
19:37 < autopsy> BustyLoli-Chan, it's no harder to dual boot than by selecting which operating system you want from the boot loader.
19:37 < edge_hay> doing batch scripting >:c
19:37 < fendur> BustyLoli-Chan: wouldn't you rather have to merely reboot to play a game than to give up on your attempt to use linux exclusively and therefore need to reinstall windows?
19:37 < edge_hay> autopsy it means you need to restart often
19:38 < fr0xk> BustyLoli-Chan: Well, honestly saying, I still don't think that linux is ready enough to that windows gaming laptops
19:38 < fr0xk> replace*
19:38 < fendur> fr0xk BustyLoli-Chan: +1 fr0xk
19:38 < autopsy> edge_hay, not if I don't play a game too often. I like Windows 10 after hating windows for ever.
19:38 < edge_hay> and either have a copy of most things or live without it from one os to another… Bash being the main thing that makes me stay away from a dual boot
19:38 < sauvin> Heh... apparently only *some* clovers are toxic (containing cyanides); most are edible.
19:38 < fendur> sauvin: phew
19:38 < uplime> which one can't eat rabbits?
19:39 < sauvin> There's a sweet clover that grows some kind of mold, I think, that contains something toxic to horses.
19:39 < edge_hay> the non edible ones uplime
19:39 < sauvin> Dunno about rabbits.
19:39 < BustyLoli-Chan> I guess... but with tools like cygwin and such do I really need linux?
19:39 < autopsy> Clovers and rabbits that's definitely off-topic.
19:39 < fendur> BustyLoli-Chan: perhaps not!
19:39 < autopsy> BustyLoli-Chan, cygwin is no Linux replacement.
19:39 < BustyLoli-Chan> also unlike windows linux runs great in a VM which means it sort of gets the short end of the stick
19:39 < edge_hay> cygwin isn't bash :/
19:39 < uplime> yeah sauvin stop going off topic
19:39 < fendur> BustyLoli-Chan: I'd say if you have to ask, and games are important, then you are likely to do just great without linux.
19:40 < compdoc> windows runs great in a vm
19:40 < BustyLoli-Chan> It's easier to run a vm of linux and have nothing go wrong imo
19:40 < autopsy> cygwin is no bash replacement that's right.
19:40 < edge_hay> Yeah but linux always runs well
19:40 < emberquill> If you think you don't need Linux, then you're probably right.
19:40 < edge_hay> it's stable
19:40 < fendur> BustyLoli-Chan: I believe you have solved it.
19:40 < autopsy> Exactly.
19:40 < BustyLoli-Chan> sadly... I love linux, but yeah
19:40 < sauvin> Windows runs great in a VM for many applications (my heavy duty mechanical engineering stuff, for example), but I don't think a VM is a great place for games.
19:40 < edge_hay> I don't know what vm you're using
19:40 < autopsy> Games use too much GPU.
19:40 < edge_hay> what vm are you using?
19:41 < revel> VirtualBox.
19:41 < sauvin> Cygwin isn't a good substitute for actual Linux because there are a few things Linux does easily that Windows can almost not do at ALL.
19:41 < dgurney> indeed, gaming in a vm will require doing complex stuff like PCIe passthrough
19:41 < BustyLoli-Chan> I do have one question though... is there a super nice virtual mixer for linux? One with virtual audio inputs and outputs and stuff?
19:41 < edge_hay> Cause apart from wine I have troubles with windows
19:41 < edge_hay> Most likely
19:41 < emberquill> When Windows 10 turned on the auto-update-and-reboot setting again after the third time I turned it off, I decided to switch fully to Linux lol
19:41 < BustyLoli-Chan> I've been using voicemeter banana to manage my audio lately, but it'd be cool if linux had a tool that does this. I imagine it'd be way better than windows since the windows audio system is sort of infected deep into the core of windows
19:42 < sauvin> I zapped my Windows partition because I hadn't used it in a couple of years and was running out of disk space.
19:42 < BustyLoli-Chan> https://www.vb-audio.com/Voicemeeter/VoicemeeterBanana.jpg
19:42 < retran> Cygwin is good at giving you a posix with glibc on in a winders box
19:43 < BustyLoli-Chan> also can I send individual program's audio to specific audio devices in linux? That would be another cool feature I'm currently missing on windows
19:43 < sauvin> There were too many things I tried to build on cygwin that just wouldn't go, found out later it's because Windows can't fork.
19:43 < qman__> linux audio is kind of a cluster
19:43 < sauvin> qman__, don't like. It's not a cluster. It's a fustercluck.
19:43 < qman__> there are a lot of options with their own shortcomings and incompatibility
19:43 < sauvin> s/like/lie/;
19:44 < BustyLoli-Chan> damn :/ I do a lot of live streaming so I would find awesome value in like a real time audio mixing capable OS
19:44 < retran> that sounds like a really spealicialized need
19:44 < qman__> look into jack
19:44 < retran> you need some specialized hardware for that
19:44 < sauvin> Also look into a low latency kernel.
19:44 < BustyLoli-Chan> I mean right now windows can do it... so I imagine linux can do it better
19:44 < autopsy> sauvin, lol Windows can't fork that's insane.
19:44 < retran> really, at the point of content creation, most people use a Mac
19:44 < sauvin> Heard that, autopsy.
19:45 < edge_hay> retran um?
19:45 < autopsy> Who can't fork.
19:45 < retran> edge_hay, um?
19:45  * edge_hay puts on sunglasses
19:45 < edge_hay> B)
19:45  * nevodka takes off sunglasses
19:45 < nevodka> :)
19:45 < edge_hay> no, noting
19:45 < sauvin> It's not necessarily true that if Windows or Mac can do it, then Linux can do it better. Mac OS X has a FreeBSD core, and in some ways will be more performant. Morover, apps built for Macs tend to have lots of money and developer time behind them.
19:45 < edge_hay> lol nevodka
19:45 < BustyLoli-Chan> hmmmm... I don't want to pirate mac OS or make a hackintosh
19:46 < qman__> windows also can't force close file handles
19:46 < retran> sauvin, right. Mac's have market inertia and lots of development "sunk costs"
19:46 < BustyLoli-Chan> also mac UI is pretty bleh in my opinion... but I do see fully where you are coming from
19:46 < qman__> if a process won't let go of a file, have to reboot, no other option
19:46 < sauvin> The forking issue forked me up royally. I decided "fork THIS!"
19:46 < autopsy> qman__, so it can lead to memory exhaustion.
19:46 < edge_hay> BustyLoli-Chan what you intended to buy windows?
19:46 < retran> for content creation applications and related hardware periphrials
19:46 < fendur> linux encourages the use of open source software. That seems key to me. :)
19:47 < sauvin> Right now, I might be tempted to snag a Mac for one reason: getting tired of kdenlive and openshot crashing.
19:47 < BustyLoli-Chan> I mean... I bought it forever ago and I've been upgraded to win10 for free so... it's been the pat of least resistance
19:47 < autopsy> Yeah where it's free that is cool.
19:47 < retran> Linux encourages the *consumption* of open source software, certainly
19:47 < lightstream> I'm having one of those moments where I've either made a daft little typo somewhere, or I have gone completely and utterly insane
19:47 < lightstream> can't work out which ATM
19:48 < fendur> retran: not the use?
19:48 < edge_hay> Bought a mac like 5 years ago
19:48 < sauvin> lightstream, so, what's the what?
19:48 < qman__> you've been "upgraded" for "free"
19:48 < fendur> retran: what is the special meaning of "consumption" here?
19:48 < retran> fendur, yes. consumption, in this case, is use
19:48 < lightstream> sauvin: i've just put a new SSD in my PC, and still have the old one mounted
19:48 < autopsy> lightstream, yeah what is going on?
19:48 < fendur> retran: I'm curious why you emphasized it.
19:48 < sauvin> lightstream, and...?
19:49 < lightstream> I want to symlink my steamapps/common folder from the new drive to the old one
19:49 < edge_hay> ln -s?
19:49 < lightstream> and i'm somehow ending up with a symlink that refers to the common folder on the new drive
19:49 < lightstream> so i mounted the old drive at /mnt
19:49 < sauvin> So, what are the device nodes to your old and new drives?
19:49 < BustyLoli-Chan> https://www.reddit.com/r/linuxaudio/comments/3wj1qf/linux_alternative_for_voicemeeter_banana/ this looks promising :O
19:50 < autopsy> lightstream, sounds like you have the source and target links backwards.
19:50 < lightstream> and use this to create the symlink: ln -s /mnt/home/compton/.steam/steam/steamapps/common /home/compton/.steam/steam/steamapps/
19:50 < lightstream> target is first right?
19:50 < BustyLoli-Chan> So does anyone know of a linux distro aimed at audio production?
19:50 < autopsy> lightstream, target is last.
19:50 < lightstream> really??
19:50 < retran> fendur, just a point I was thinking for some reason about use vs. development
19:50 < sauvin> Really.
19:50 < edge_hay> BustyLoli-Chan macos
19:50 < autopsy> lightstream, ln -s source target
19:50 < edge_hay>  :/
19:50 < BustyLoli-Chan> >_>
19:50 < edge_hay> Not really open source
19:50 < lightstream> oh ok there's my silly little typo lol
19:50 < BustyLoli-Chan> okay... okay... fair enough.. but yeah
19:51 < sauvin> Congratulations, lightstream, and welcome to the club. You've just been initiated. We've ALL done that. :D
19:51 < autopsy> lightstream, yeah you just have them switched around that's all change the order.
19:51 < edge_hay> arch is lightweight
19:51 < fendur> retran: I see. That's what I thought. I would guess it also, perhaps more subtly, encourages development. But I don't know about that.
19:51 < lightstream> heh ok so not going insane just yet :D
19:51 < sauvin> o/~ welcome to my nightmare... o/~
19:51 < BustyLoli-Chan> I've used slackware before... I love it, but it's kind of a pain and not easy... I'd be interested to try Arch
19:51 < BustyLoli-Chan> I heard they are similar in many ways, but Arch is probably easier and has sexier package managers and such
19:52 < retran> fendur, it sounded better in my mind before I actually tried articulating it :p
19:52 < edge_hay> I like cinnamon as a gui
19:52 < edge_hay> (Please don't hurt me)
19:52 < autopsy> I was using Slackware 1.2.1 kernel when I started using Linux we had to connect our dial up modems using minicom and pppd
19:52 < RonWhoCares> How do I run "ls" without it using the predfined alias
19:52 < edge_hay> kde is nice too
19:52 < sauvin> edge_hay, I'm a KDE fanatic. People who "ugh" at me, I just tell them "Hey, you don't like it, don't look!"
19:52 < BustyLoli-Chan> looks like... windows 8D
19:52 < emberquill> RonWhoCares: "command ls"
19:52 < ksk> eh, ln its syntax is "target linkname"!? im confused :D
19:52 < BustyLoli-Chan> I actually like KDE
19:52 < AnAverageHuman> RonWhoCares: /bin/ls
19:53 < emberquill> Or that ^
19:53 < BustyLoli-Chan> I wanted to try gnome, but never found a distro that was naturally capable of it
19:53 < AnAverageHuman> or `$(which ls)`
19:53 < retran> BustyLoli-Chan, is that a joke/troll?
19:53 < autopsy> ksk, no ln -s source target
19:53 < edge_hay> I mean I used to have gnome on ubuntu but that's when they still mailed you free cds
19:53 < edge_hay> 08.04 I think
19:53 < ksk> autopsy: show me the manpage
19:53 < uplime> AnAverageHuman: gross
19:54 < BustyLoli-Chan> no?... slackware never had a gnome package and I never could figure out how to get it working
19:54 < emberquill> Ubuntu's switching back to gnome though (if they haven't already, can't remember if that's a 17.10 or 18.04 change)
19:54 < autopsy> ksk, that's what it is I'm telling you.
19:54 < uplime> RonWhoCares: \ls
19:54 < autopsy> ksk, man ln
19:54 < ksk> I have the manpage open, it says "       ln [OPTION]... [-T] TARGET LINK_NAME   (1st form)
19:54 < fendur> whoa. people still use slackware?
19:54 < ksk> "
19:54 < azarus> fendur: yes
19:54 < retran> yep. ubuntu is all "done" with their Unity experiment
19:54 < autopsy> ksk, yes link is last.
19:54 < azarus> slackware is kinda cool
19:54 < edge_hay> What's slackware?
19:54 < autopsy> ksk, I said target I meant link.
19:55 < BustyLoli-Chan> slackware teaches you lots, but makes you want to cry imo
19:55 < fendur> azarus: indeed, it will always have a cool factor for me. I started with slackware.
19:55 < azarus> edge_hay: a distro
19:55 < ksk> okay, a play on words :P
19:55 < retran> Slackware is an old nearly-dead distro
19:55 < BustyLoli-Chan> *makes me want to cry imo
19:55 < edge_hay> oh
19:55 < autopsy> azarus, I used Slackware when you had to install from 44 floppy disks.
19:55 < azarus> one of the oldest distros around
19:55 < autopsy> It was a long process.
19:55 < RonWhoCares> uplime: What is the ls syntax that would output  /home/rpiggott/filename.txt     (I don't want the date, permissions or size to be listed)
19:55 < sauvin> ksk, last time I issued an ln -s, I supplied only ONE argument, the source: ln -s /maison/sauvin/autrui/charges/flics
19:55 < azarus> hehe, I wasn't alive when floppies were around
19:55 < sauvin> ksk, it created a link to that directory in the current directory.
19:55 < uplime> RonWhoCares: \ls /home/rpiggott/filename.txt
19:55 < azarus> and yet I still use them
19:56 < fendur> autopsy: thankfully I didn't start using slackwaare until 1995 when CDs were a thing.
19:56 < retran> if you want a bare-bones Linux, perhaps try Alpine?
19:56 < retran> you can feel all hard-core
19:56 < edge_hay> sauvin you speak French? :o
19:56 < sauvin> Once upon a time, yes.
19:56 < retran> Alpine is nice because it at least has package management of sorts
19:56 < autopsy> fendur, I used Slackware with kernel 1.2.1 in 1995 I think also.
19:56 < edge_hay> I like debian
19:57 < edge_hay> Never tried it with a gui tho
19:57 < autopsy> retran, Fedora has package management.
19:57 < fendur> 1.2.8 or 1.2.13 sounds more like it. But I can't recall. Maybe it was 96.
19:57 < sauvin> I use debian for servers. I like debian more than anything else I've ever tried, but when slapping something onto a NEW computer, I'll often use kubuntu because better OOTB drivers.
19:57 < BustyLoli-Chan> lol fedora
19:57 < azarus> autopsy: fedora has completely different goals than alpine
19:57 < azarus> fedora is *huge*
19:57 < sauvin> Ain't tiny!
19:57 < BustyLoli-Chan> our school used to use red hat on all their machines
19:57 < autopsy> fendur, wow that's crazy I was using usbnet over a USB ethernet cord to get internet on my machine.
19:57 < azarus> a base alpine install will run you like ~130MB
19:57 < BustyLoli-Chan> it was just like... why
19:57 < revel> Alpine has really old kernel versions...
19:58 < azarus> revel: nope
19:58 < revel> azarus: No?
19:58 < dgurney> I use Gentoo basically everywhere atm
19:58 < azarus> revel: use linux-vanilla on edgte
19:58 < azarus> you get the latest long-term kernel
19:58 < revel> azarus: When was the current linux-vanilla kernel built?
19:58 < autopsy> What is a long term kernel?
19:58 < revel> Please, tell me it wasn't in 2017.
19:58 < azarus> revel: a couple of days ago
19:58 < edge_hay> :o
19:58 < revel> Oh, good.
19:58 < sauvin> BustyLoli-Chan, there's an argument for red hat in schools because many major businesses use RHEL.
19:58 < revel> The one before it?
19:59 < retran> autopsy, and so do a billion others distros. Alpine is an example of really small bare-bones distro (fork of Busybox)
19:59 < lightstream> huh i see ksk said what i was about to
19:59 < BustyLoli-Chan> https://upload.wikimedia.org/wikipedia/commons/thumb/2/2d/RedHatHeadquartersRaleigh.jpg/1024px-RedHatHeadquartersRaleigh.jpg :O
19:59 < azarus> retran: they don't have a fork of busybox
19:59 < lightstream> target is first.. right?
19:59 < azarus> they just have a couple of patches
19:59 < fendur> autopsy: yeah. old school. diald with a 14.4k :)
19:59 < autopsy> lightstream, ln -s target symlink
19:59 < edge_hay> Same as cp or mv
20:00 < sauvin> The word "target" confuses me, so I tend to think in terms of "source" and "destination".
20:00 < edge_hay> btw is there like cpdir? :/
20:00 < autopsy> fendur, that was some good old fashioned work there. Dialup is hard to keep alive with bad telephone lines.
20:00 < ksk> edge_hay: cp -R?
20:00 < retran> azarus, say what?
20:00 < ayecee> i get confused when i think "source" and "destination", so i tend to think in terms of "target"
20:00 < edge_hay> ksk yeah I assumed
20:00 < azarus> retran: busybox is alpine's userland
20:00 < azarus> that's all it is
20:00 < azarus> no fork
20:00 < retran> k
20:01 < autopsy> busybox is small 130 MB install is small.
20:01 < retran> yep
20:01 < autopsy> Yeah what is a fork of busybox anyways?
20:01 < azarus> autopsy: a deviation of busyboxes codebase
20:01 < autopsy> Alpine sounds like trees man.
20:01 < autopsy> azarus, I see.
20:01 < azarus> autopsy: also you asked what a long-term kernel is?
20:02 < azarus> autopsy: go on kernel.org and see "long-term"?
20:02 < dgurney> it's a kernel that is supported for several years
20:02 < autopsy> azarus, yeah never heard that term.
20:02 < dgurney> that's it really
20:02 < autopsy> So it deals with support.
20:02 < lightstream> ok so I may yet have gone insane. From ~/.steam/steam/steamapps, I run "ln -s /mnt/home/compton/.steam/steam/steamapps/common /home/compton/.steam/steam/steamapps/"
20:02 < azarus> 4.14 will be supported for 6 years, i believe
20:02 < revel> azarus: Where'd you get the "a couple of days ago" date?
20:02 < lightstream> and when I check the symlink, I see: "common -> /mnt/home/compton/.steam/steam/steamapps/common"
20:02 < azarus> revel: pkgs.alpinelinux.org
20:02 < revel> The mirror seems to say the linux-vanilla package was last touched on "2017-Nov-24 19:12:34"
20:03 < azarus> your mirro is terrible then
20:03 < lightstream> but when I do "ls common" I get "ls: cannot access 'common': Too many levels of symbolic links"
20:03 < azarus> revel: https://pkgs.alpinelinux.org/package/edge/main/x86_64/linux-vanilla
20:03 < azarus> 2018-04-02 07:48:25
20:03 < revel> azarus: The official one...?
20:03 < revel> https://nl.alpinelinux.org/alpine/latest-stable/main/x86_64/
20:03 < azarus> i said edge
20:03 < azarus> not stable...
20:03 < RonWhoCares> I don't get why the output of ls to the screen and piping to the file isn't the same.   When it pipes the output to the file it includes the file details.  I don't want this
20:03 < revel> azarus: When?
20:04 < revel> Oh, "edgte"
20:04 < azarus> whoops
20:04 < autopsy> The actual symlink target goes last.
20:04 < ayecee> RonWhoCares: how are you piping the output to a file
20:04 < delt> getsubopt () is defined in stdlib.h right?
20:04 < delt> on termux i'm getting a linker fail on that symbol
20:04 < autopsy> I keep saying target it's a symbolic link to a directory or file.
20:04 < RonWhoCares> ayecee: command \ls /home/rpiggott/Videos/youTube/*/*.mp4 >> /var/tmp/youTube_mp4_exclude
20:05 < ayecee> RonWhoCares: what output do you get
20:05 < delt> i'd ask in #c but their channel is locked or something
20:05 < azarus> delt: ##c
20:05 < lightstream> The old SSD is definitely mounted at /mnt - "/dev/sda2 on /mnt type ext4 (rw,relatime,data=ordered)"
20:05 < RonWhoCares> ayecee: Please look at the pastebin  https://pastebin.com/DLL0B5u6
20:05 < sauvin> Where's the new SSD mountd?
20:05 < RonWhoCares> ayecee: - I've included the results
20:05 < ayecee> RonWhoCares: could you delete the file and try again
20:05 < delt> azarus: oh :) #c was redirecting to #namespace which gives me "cannot send to channel"
20:06 < delt> anyway thanks
20:06 < RonWhoCares> Weird
20:06 < RonWhoCares> ayecee: Why didn't the file get over wrote?
20:06 < ayecee> because >> appends
20:06 < RonWhoCares> So I just didn't scroll down
20:07 < RonWhoCares> Bother!
20:07 < ayecee> :)
20:07 < RonWhoCares> Can I over write the file?
20:07 < autopsy> RonWhoCares, to overwrite the file use only one > this time.
20:07 < RonWhoCares> Bother!
20:07 < RonWhoCares> autopsy: Do you perform counseling?
20:07 < RonWhoCares> :)
20:07 < azarus> this is like, standard UNIX stuff
20:07 < autopsy> RonWhoCares, yeah >> appends to the last line > will create a new file. Or overwrite whichever you think of.
20:08 < autopsy> No I have no interest in counseling command output redirection isn't so hard to understand though.
20:09 < autopsy> RonWhoCares, you are writing a script or what?
20:09 < lightstream> ok it has to be something to do with this higher level symlink: "/mnt/home/compton/.steam/steam -> /home/compton/.local/share/Steam"
20:09 < autopsy> RonWhoCares, cause you could just put it in a bash script.
20:09 < retran> "bash script" or not, it's the same thing
20:09 < lightstream> right, i need to use the resolved symlink as the target, not the symlinked one i guess
20:10 < lightstream> phew, insanity averted
20:11 < autopsy> lightstream, test making symlinks in /tmp symlink a file in temp to another name in the same directory you'll see what you are doing.
20:11 < bray90820> is there a way to do something like du -sh for the sizr of a drive instead of a directory?
20:11 < azarus> bray90820: df -h
20:11 < autopsy> df -h disk free
20:11 < bray90820> Thanks
20:11 < autopsy> Free is not used.
20:11 < autopsy> But df might get you what you need.
20:12 < autopsy> lightstream, did you fix it?
20:12 < lightstream> yep i've sussed it now autopsy - it was because my target was /mnt/home/compton/.steam/steam/steamapps/common but /mnt/home/compton/.steam/steam is a symlink to /home/compton/.local/share/Steam
20:12 < lightstream> so i need to use /mnt/home/compton/.local/share/Steam in my target instead
20:13 < autopsy> lightstream, sounds like you had them reversed at first remember to rm the symbolic link though before you try to link it again.
20:14 < lightstream> actually i did have them the right way round to begin with
20:14 < lightstream> it was just the symlink in the target meant i was creating a symlink to the new drive
20:15 < RonWhoCares> Thank you one and all.  It worked.  (Not to mention I appreciate the mohawk you gave me in the process :p )
20:15 < autopsy> lightstream, you were creating a symlink to a symlink that is why it gave you too many levels error.
20:16 < autopsy> RonWhoCares, just remember command ls or \ls and > or >> to append more files to the file.
20:16 < lightstream> yeah, but only because /mnt/home/compton/.steam/steam/steamapps/common resolves to the new drive
20:16 < lightstream> "realpath /mnt/home/compton/.steam/steam/steamapps/common" ---> "/home/compton/.local/share/Steam/steamapps/common"
20:17 < autopsy> I don't know what steamapps is.
20:17 < lightstream> it's the folder where steam stores downloaded games
20:18 < lightstream> i want this symlink so i don't have to re-download them
20:18 < lightstream> (of course i could just move them, but don't want to just yet)
20:19 < lightstream> main thing is the output of realpath above doesn't contain /mnt at the beginning
20:19 < autopsy> lightstream, it redownloads them if they don't exist I guess.
20:19 < autopsy> lightstream, /mnt is where you have the old drive mounted right?
20:20 < lightstream> yep
20:20 < autopsy> Hm.
20:20 < lightstream> (yep to both)
20:20 < amelliaa> Oi, can MPV mono a video with a hotkey or something like that?
20:24 < phogg> amelliaa: not so easily, but you can likely apply a filter to do that
20:30 < mawk> what's a sane value to use when throttling block I/O to a disk ?
20:30 < BCMM> amelliaa: mono like monochrome, or mono like single-track audio?
20:30 < mawk> for a sandboxed process and its children
20:30 < ksk> mawk: that depends? ;)
20:30 < mawk> so for a single process
20:30 < amelliaa> BCMM: single-track audio
20:30 < mawk> yeah I know, that's why it'd be the default value
20:30 < ksk> like, on the throughput of your disk, and on your priorities
20:30 < mawk> the sandboxed process doesn't have to do anything with the disk normally
20:30 < ksk> there is no sane default, and there can be no sane default imho.
20:31 < mawk> but it could maybe load a couple of shared libraries, or write small files to the disk
20:31 < ksk> so dont limit it then?
20:31 < BCMM> amelliaa: -audio-channels=downmix does that, but i'm not sure if you can do it after the video has started playing
20:31 < mawk> yeah but then it allows malicious uses
20:31 < ksk> like, I like cgroups and stuff, but if disk usage is never an issue, why bother?
20:31 < mawk> the sandboxed process can steal all the bandwidth
20:31 < amelliaa> BCMM: Alright, thanks.
20:31 < BCMM> amelliaa: (presumably, downmix means "mix both channels together, and put the result on both speakers". i think there are options for if you want *only* the right or left channel)
20:31 < mawk> the goal is to prevent the process from doing harm
20:32 < ksk> yeah okay, if you want to protect your hardware vs. the VM/box/whatever
20:32 < ksk> it then depends on "how much do I want to give a single box" - in contrast to what your hardware offers
20:32 < mawk> yeah
20:32 < mawk> that would be to find an upper limit
20:33 < ksk> I would assume these kind of settings are more like big company secrets, and there are no defaults around.
20:34 < ksk> also heavily depends on the programms running in the limited context, like you run a wordpress blog and say "uh, I monitored it and apply these settings, they are fine"
20:34 < mawk> yeah
20:34 < mawk> it would be for a programming language sandbox
20:34 < mawk> so really anything could run in it
20:35 < BCMM> amelliaa: actually, looks like that option *might* be aimed at downmixing surround to stereo. an example in the man page recommends --af=pan=1:[0.5,0.5]
20:35 < ksk> also, AFAIK its not just "disk IO" its split up into different things like "read/write over a timeframe" or "number of files craeted" or whatever low-level speech applies here
20:35 < ksk> but its an intersting approach
20:35 < mawk> here I can control either iops or bytes per second
20:35 < ksk> some guy on #lxd fought with lxd to archive something like this and had some problems (like cgroups not recent enough etc)
20:36 < mawk> or use a more complex approach using equal time shares or something
20:36 < mawk> cgroups not recent enough ? lol
20:36 < mawk> cgroups v2 maybe
20:36 < ksk> yeah, that sounds like it.
20:37 < amelliaa> BCMM: My mpv didn't seem to have downmix option available, but --audio-channels=mono or --af=pan=1:[0.5,0.5] do what I was looking for. No need to search for this anymore and thanks for help
20:38 < mawk> but blkio is in cgroups v1 since 2009
20:38 < mawk> that's recent enough for me
20:39 < hasdf> hi. Is there any good tutorial for how to use (GNUPG-) Smartcards? (e.g.: Enigmail, Login via PAM, LUKS-Encryption, etc)
20:40 < hasdf> or one of the examples
20:42 < mawk> let's take a statistical approach, the glibc is around 2 MiB, I want the startup time to be less than 100ms for instance, that would make 20 MiB/s of read speed
20:42 < mawk> that seems high
20:42 < mawk> but it's a dumb estimate anyway, glibc is already loaded for anyone to use
20:43 < za1b1tsu_> anyone running linux on vmware fusion, what is the distro you had no problems with? I tried lubuntu and it crashes a lot
20:43 < mawk> crashes when doing what ?
20:44  * sauvin is running kubuntu on bare metal and gets fried out at openshot and kdenlive constantly crashing
20:44 < revel> "Oh, you know, writing random data to /dev/kmem"
20:44 < mawk> lol
20:44 < ayecee> za1b1tsu_: i haven't had a problem with *ubuntu on vmware. maybe examine the crashes to understand what's happening.
20:44 < phogg> if you're crashing doing video editing that's sadly normal
20:45 < za1b1tsu_> mawk, updating sofware etc
20:45 < sauvin> phogg, some reading around suggests you're 100% spot on.
20:45 < sauvin> za1b1tsu_, how are you doing the "updating"?
20:45 < phogg> sauvin: I keep trying the various editors out there and it keeps being true, except for Blender which I just don't understand
20:45 < za1b1tsu_> sauvin: after installation, I was asked to update the os
20:46 < ayecee> saw an error and ran away
20:46 < za1b1tsu_> software update center?!
20:46 < sauvin> I came to Blender. I saw Blender. Blender's user interface kicked my ass.
20:46 < ayecee> it's broken. make it go so we can be strong.
20:47 < phogg> sauvin: after 30 minutes being unable to do anything I tried a video tutorial, but it was for a slightly different version or something and the UI was entirely different. After another 30 minutes I went back to mpgtx and mencoder for my simple slicing needs. Maybe next year.
20:47 < revel> sauvin: Whoah, now, how do you get that excited for video editing software?
20:47 < sauvin> Blender is "video editing software"?
20:47 < phogg> sauvin: amongst other things
20:47 < sauvin> And no, next time I try taking on Blender, I'm wearing body armour.
20:48 < revel> sauvin: Well, either way, how'd you come to it?
20:48 < Psi-Jack> Oh yay.. Nick change flooding.
20:48 < phogg> blender must, as part of its job, be able to do what amounts to video editing. I would not say it's designed for it
20:48 < mawk> sauvin tripped on freenode's cable
20:48 < revel> Psi-Jack: Netsplit.
20:48 < Psi-Jack> Ahh. Been a while. :0
20:48 < revel> Oh, that too.
20:48 < phogg> at least it's not another matrix sync
20:48 < Psi-Jack> sauvin: Stop driving a forklift through freenode's data centers. :)
20:48 < sauvin> revel, somebody asked something about video editing software, so I loaded up two or three things to poke at to try to help. Wound up "accidentally" plopping some Alice Cooper onto a romantic scene and laughed my ass off.
20:49 < sauvin> Psi-Jack, wasn't me, but some of the guys I share a warehouse with are guys I would NOT want to share a highway with.
20:49 < Psi-Jack> hehehehe
20:50 < revel> sauvin: Yeah, right. What, was it your cat?
20:50 < sauvin> I presume somebody at a DC somewhere farted, and there weren't any open windows.
20:50  * Acheron-a loveS fartS *
20:50 < sauvin> Either that, or Freenode has something running on a Windows machine.
20:51 < revel> Acheron-a: I'd personally prefer it if you kept that to yourself...
20:52  * Acheron-a haS farted a few times behind server racks and left the scene *
20:52 < Psi-Jack> No blaming Garfield this time. :)
20:53 < bipul> When we change the passphrase of RSA private key. Could we able to see the changes inside the file? i.e id_rsa ?
20:54 < Psi-Jack> bipul: Of course.
20:55 < bipul> Psi-Jack, I have tried to figure it out, at head id_rsa but nothing new i have seen.
20:55 < Psi-Jack> Please... English.
20:55 < bipul> It was for me?
20:56 < ayecee> probably yes
20:56 < revel> Considering there's nobody else chatting? Yes.
20:56 < bipul> Ah, okay i will try my best. :)
20:56 < Psi-Jack> "at head id_rsa" makes no sense.
20:57 < bipul> I mean to say here is that, i used the command "head id_rsa"  to check the changes after resetting the passphrase.
20:57 < Psi-Jack> ... Why?
20:58 < Psi-Jack> cp id_rsa id_rsa.orig; change passphrase; diff id_rsa id_rsa.orig
21:02 < bipul> I have two VM's VM1 and VM2. At VM1 i have copied my ssh keys too VM2, and then i have reset the passphrase of my private key on VM1. For just curiosity, i thought i should check the changes inside private key file i.e id_rsa. But i found nothing new in it.
21:04 < Psi-Jack> And yet. Did you do what I said?
21:04 < Psi-Jack> Sounds like. No.
21:04 < revel> How'd you check for changes?
21:04 < ayecee> he stopped at the first question
21:04 < Psi-Jack> revel: Somehow, with "head"
21:04 < Psi-Jack> heh
21:10 < bipul> Psi-Jack, I thought DEK-Info will be changed.
21:11 < sine0> when you mkfifo NAME do you have to kill that name when your done
21:12 < revel> sine0: No, you can leave it there forever if you want.
21:12 < revel> It'll take up an inode, I think, and maybe clutter up a directory slightly, but other than that, you can reuse them to your heart's content.
21:13 < sine0> but for the sake of ocd, I mean aspergus, I mean tidyness, how do i remove it
21:13 < revel> rm
21:13 < revel> Or unlink, maybe?
21:14 < Psi-Jack> ...
21:14 < Psi-Jack> sine0: Bad example. :p
21:14 < sine0> Psi-Jack: ?
21:15 < Psi-Jack> Insulting people with actual OCD, or Aspergers, is not very nice.
21:15 < Psi-Jack> So, bad example. :p
21:15 < Manis> Hi. When I create a file "dd if=/dev/zero of=file bs=1M count=100" and then try to extend it (incorrectly) "dd if=/dev/zero of=file bs=1M count=10 skip=100", is the rest of the file still on the disk?
21:16 < Essadon> Hello, I have a relatively simply question. I have this regex https://regex101.com/r/K0Bqtl/2 and it does what it's supposed to do, except that the part after Participants: [NAME] ends with <p> tag instead of a <div>-tag. I want both tests to match
21:17 < sine0> Sigh-Jack
21:18 < kurahaupo> Manis: looks like a sparse file - 110MB apparent size, but only occupying 20MB. If you later write something to the middle 90MB its space usage will increase
21:18 < kurahaupo> Manis: if you read from the sparse portion it will return NUL bytes
21:19 < Manis> kurahaupo: Are you sure? skip seeks in the _input_, not in the output.
21:19 < Manis> Because what you describe would actually have been what I wanted.
21:19 < Manis> Essadon: Participants: .+?(?=<div|p)
21:20 < kurahaupo> Oh, right. I read seek=100, sorry. No it just overwrites the existing 10MB
21:20 < Essadon> Manis: Does that match either 'div' or 'p'? Or a random combination?
21:21 < Manis> Essadon: random combination?
21:21 < Essadon> Like dp, dip, dvp
21:22 < Manis> Essadon: Ah, yeah, true. Put the div in quotes ("div").
21:23 < bipul> If i have to remove the passphrase from the private key. How would i do that? Do i need to use "openssl rsa" ? Is it mandatory to use?
21:23 < hexnewbie> Essadon: You may try DOM and xpath instead
21:23 < Manis> Ehrm, my brain is broken. in () not in "".
21:24 < Essadon> Manis: What in " "?
21:24 < Manis> kurahaupo: But then the rest 90MB should still be there, no?
21:24 < Essadon> group the div?
21:25 < Essadon> Manis: Like Participants: .+?(?=<(div)|(p)) ?
21:25 < Manis> Essadon: Participants: .+?(?=<(div)|<(p))
21:25 < Essadon> lol
21:25 < Essadon> yeah
21:25 < Manis> yeah, like that, but don't forget the < before the (p).
21:25 < Essadon> Thanks
21:26 < prussian> bipul: openssl rsa -passin something -in your/key
21:26 < kurahaupo> Essadon: why do you use look-ahead in your regex?
21:27 < prussian> where passin can take soemthing like env:envvar, file:file or file:<(something)
21:27 < prussian> etc
21:27 < bipul> Without OpenSSL is it not possible? if not then why? :)
21:27 < kurahaupo> Manis: the extra brackets around (div) and (p) don't serve a useful purpose
21:28 < prussian> it's possible? just a lot of implementation details that would have to implemented by someone...
21:28 < Manis> kurahaupo: Well they do around div, so that all three characters need to match
21:28 < prussian> not a fan of openssl's command line ux either.
21:29 < bipul> Okay thank you prussian .
21:29 < kurahaupo> Essadon: /Participants:\s*(.*?)<(?:div|p)\b/
21:30 < noway96> I'm getting a segmentation fault for QtWebKit
21:30 < noway96> The debugging procedure should be 1. gereate core file 2. look at it
21:30 < noway96> yes?
21:31 < kurahaupo> Manis: if it's PCRE, which it certainly appears to be, then no. (…) creates a match group, […] creates a match class
21:31 < Manis> kurahaupo: Don't you use a match group in your regex, too? (apart from it being non-capture.
21:33 < Manis> In my dd tests after the failed "skip", the file only has the size
21:34 < kurahaupo> Manis: I write (div|p) not ((div)|(p))
21:34 < Manis> of the "extension" (the amount I tried to add). But in my data loss case, the file has the size of the used part of the file. How can that be?
21:34 < prussian> fallocate or truncate. why are you growing/making NUL byte files with dd?
21:34 < Manis> kurahaupo: Ah, that you meant. Yeah, correct.
21:34 < kurahaupo> Manis: dd does not truncate the target file
21:35 < Manis> prussian: Because I've always done it this way. There is no real reason.
21:35 < kurahaupo> prussian: there are many uses for such
21:35 < Manis> kurahaupo: What do you mean with "not truncate"?
21:36 < kurahaupo> Manis: it's not the same as the shell >| redirection
21:36 < xz> is anybody using slack here? I have $50 deal and wondering if it's worth to purchase yearly membership ($80 - $50 = $30 at checkout)
21:36 < xz> I'm new to slack, haven't explored it much so far
21:36 < hexnewbie> Slackware is offering yearly membership?
21:36 < xz> slack communicator, ha
21:36 < Psi-Jack> hexnewbie: LOL
21:36 < JimBuntu> xz, Yes, it's worth it
21:37 < Psi-Jack> xz: Got a Linux quesation?
21:37 < kurahaupo> Manis: the shell passes O_TRUNC when it calls open(), dd does not. Read man 2 open
21:37 < Psi-Jack> xz: Rocket.Chat and MatterMost, you can run on your own server, for free.
21:37 < xz> I would imagine many of #linux are using slack, couldn't find better place on freenode really
21:37 < Psi-Jack> Slack though has /nothing/ 0% to do with Linux.
21:38 < xz> Psi-Jack,  you are 100% right sir
21:38 < Essadon> kurahaupo: Because I want to do that
21:38 < JimBuntu> Well Psi-Jack They do have a native Linux app (I think it's simply electron)
21:38 < Psi-Jack> JimBuntu: They have an Electron crappy app, sure.
21:41 < kurahaupo> Essadon: I mean instead of using a simple (non-capturing) match group. Typically one would want the content without the "participants" label, so apply a capture group directly to the "content"
21:42 < kurahaupo> Essadon: as I did in my suggested version
21:43 < Manis> kurahaupo: I don't really understand what the pipe does in >|, but then I don't really understand this: https://pastebin.com/Nrs7TVr8
21:44 < noway96> To have unlimited core dump size and change the core path, I'm thinking of calling executables inside rc.local. It's systemV. Objections?
21:45 < Dagmar> Yes.
21:46 < kurahaupo> Manis: oh, it's the same as > but overrides the noclobber option
21:46 < hexnewbie> noway96: Where shall I submit a formal complaint? :)
21:46 < Dagmar> You can additionally change your desktop icons, because they *also* have nothing to do with core files
21:46 < noway96> it'll be ulimit -c inlimited; sysctl -w "kernel.core_pattern=<filename>";
21:47 < hexnewbie> ulimit is not an executable
21:47 < Dagmar> noway96: If you just set the things for that in sysctl.conf and reboot you'll be done
21:47 < noway96> oh what is it?
21:47 < kurahaupo> noway96: ulimit is a shell built-in
21:48 < hexnewbie> noway96: A shell built-in. Changes the limits for the current shell and all children (nothing would be a child of rc.local's shell, except for the stuff you launch from there)
21:48 < Dagmar> Where core files land is exclusively the domain of the kernel, man.  All you need to do is set them in /etc/sysctl.conf
21:48 < notadrop> Why doesn't this work: "su $current_user vi"
21:48 < Dagmar> Trying to change them in rc.local is silly
21:48 < notadrop> /usr/bin/vi: /usr/bin/vi: cannot execute binary file
21:49 < mawk> because you don't use su like that
21:49 < hexnewbie> noway96: You may look at /etc/security/limits.conf for changing the limits
21:49 < mawk> su -cvi
21:49 < notadrop> maybe I should RTFM
21:49 < noway96> yeah I guess I have no real linux education. How do I get that, they don't teach it in university
21:49 < notadrop> Linux+ cert course?
21:50 < Dagmar> noway96: Reading man pages and docs
21:50 < notadrop> and that^
21:50 < noway96> I like books
21:50 < nnull> Books like you more
21:50 < hexnewbie> noway96: Lucky you. They taught me that at university.
21:50 < noway96> Also apparently my custom linux image doesn't have sysctl.conf
21:51 < noway96> But it does have sysctl
21:51 < Dagmar> noway96: Well, you might want to fix that then.  Most distros use that filename and feed it to sysctl at some point early in the boot process
21:51 < Manis> kurahaupo: I still don't get it? If dd does not truncate, how can the file be smaller afterwards?
21:51 < Dagmar> It might be that it's just not there because there's no point in even having a file if you're not setting in anything in it
21:51 < hexnewbie> You can call ulimit at top of the food^Wcall chain
21:52 < hexnewbie> Or would that be bottom?
21:52 < Dagmar> I wouldn't even bother with trying to set the core size limit unless you think it's ridiculously small or something
21:53 < Dagmar> You kinda want an upper bounds on that one
21:53 < kurahaupo> Manis: ok now I'm confused. Did you use dd … of=file or dd … >file ?
21:53 < Manis> kurahaupo: of=.
21:53 < Dagmar> Manis: THat's almost never going to be a good idea
21:53 < Manis> kurahaupo: Did I ever write I used >?
21:53 < kurahaupo> Manis: what was the size afterwards?
21:54 < kurahaupo> Manis: no, but I've been following 4 conversations so I forget, sorry
21:54 < noway96> hexnewbie what?
21:54 < Manis> kurahaupo: In the example? 10MB. In my real case the combined size of all LVs.
21:54 < Dagmar> dd isn't going to append to an output file, and pointing it at the current directory is a real bad idea
21:54 < noway96> Dagmar, ok just some blogs said to set it to unlimited
21:54 < kurahaupo> Manis: wasn't it already 10MB?
21:55 < Dagmar> noway96: Under certain circumstances it can be _disk consumingly_ large
21:55 < Manis> Dagmar: Oh no, I didn't really type "of=." The . was just a full stop.
21:55 < Dagmar> Ah okay
21:55 < Dagmar> *whew*
21:55 < hexnewbie> noway96: Are you trying to debug daemons, user-started programs (UI), programs started in command-line, or?
21:55  * kurahaupo understood that
21:55 < Manis> kurahaupo: No. First run is 100MB, then I add another 10MB
21:56 < Dagmar> noway96: What is this distro you're working with?
21:56 < noway96> Dagmar, it's custom image using yocto
21:56 < Manis> kurahaupo: Check this example case out: https://pastebin.com/Nrs7TVr8
21:56 < Dagmar> noway96: So... sysv-based?
21:56 < noway96> yep
21:57 < noway96> hewnewbie, it's a program started on bootup by an x11 init script
21:57 < noway96> using the exec call
21:57 < hexnewbie> noway96: Then set the ulimit in that x11 init script
21:57 < noway96> oh
21:57 < hexnewbie> before calling that program
21:57 < Dagmar> noway96; So... You may find it illuminating if you just go into /etc/rc.d and do a `grep -R sysctl`
21:58 < Dagmar> er... with an * at the end
21:58 < Dagmar> noway96: THen you'll see where/if it's pulling in /etc/sysctl.conf
21:58 < Dagmar> It *should* be
21:58 < kurahaupo> Manis: ok, clearly it's my turn to go back and learn something. That's not what I expected.
21:58 < Manis> Me neither.
21:58 < Dagmar> That's kind of a no-brainer for a distro *ahem* with a kenrel
21:59 < hexnewbie> noway96: Hm, I am sorry. That won't work. You wouldn't be allowed to, as your core size would already be limited at login. :/ You need limits.conf in some capacity supported when your user session is started.
21:59 < kurahaupo> Manis: if it's a block device rather than a file, the length is implicitly fixed so O_TRUNC or not makes no difference
21:59 < kurahaupo> Which is what I'm more used to doing with
21:59 < Manis> kurahaupo: Ah. That does make a lot of sense.
22:00 < noway96> hexnewbie, I'll try it anyway
22:00 < Manis> kurahaupo: So dd truncates, too?
22:00 < kurahaupo> Manis: gotta dash. Bb later
22:00 < Dagmar> Not unless you have really gone out of your way with options
22:00 < Dagmar> dd's operation is _very simple_
22:01 < Dagmar> Without being told otherwise, it'll open files with a simple open() call, write to them with simple write calls, and simply close them when it's done
22:01 < Manis> Yeah, sure. But that just doesn't add up in my head.
22:01 < Dagmar> It won't seek or truncate or sync or anything unless you tell it to explicitly
22:02 < kurahaupo> Dagmar: that's what I expected, so what accounts for Manis' paste?
22:02 < Dagmar> No idea.  Lemme scroll up and se
22:03 < hexnewbie> dd has conv=notrunc and conv=nocreat, as well as flag=append, so I assume O_CREAT|O_TRUNC is the default
22:03 < koala_man> Manis: what is unexpected about it?
22:03 < Dagmar> Are we talking about this paste? -> https://pastebin.com/Nrs7TVr8
22:03 < hexnewbie> Although I'm much confused by the existence of separate conf=notrunc flag=append which you're supposed to use together
22:03 < Dagmar> I dont' see anything unusual there
22:04 < Manis> Hmm. Maybe I'm too used to working with block devices and dd. With block devices it's possible to overwrite a part of the device with data.
22:04 < Manis> But with files it apparantly overwrites the whole file each file.
22:04 < koala_man> you're not overwriting a part of the device, you're overwriting the device with parts of the data. maybe you wanted seek=100 instead
22:04 < Manis> s/file$/time/
22:05 < kurahaupo> hexnewbie: O_APPEND doesn't just mean start writing from the end, it means every write is at the end
22:05 < kurahaupo> koala_man: that was the original question
22:05 < Dagmar> Yeah, "skip" is something that only affects the input
22:05 < Manis> Yes, I did want to seek=, which is the very reason I destroyed my data ;-)
22:05 < hexnewbie> kurahaupo: Ah, right
22:05 < koala_man> cool
22:05 < Dagmar> Manis: Well, that's the other thing "dd" stands for... "data destroyer"
22:06 < Dagmar> *do-do do-doooo* The more you know...
22:06 < Manis> -.-
22:06 < dgurney> am I strange for never having messed up with dd?
22:06 < Dagmar> dgurney; Nope
22:06 < JimBuntu> dgurney, yes
22:06 < koala_man> most people have never messed up with dd
22:06 < koala_man> but then most people have never used it
22:06 < Dagmar> koala_man: I'm not so sure about that
22:06 < hexnewbie> dgurney: One shouldn't have to. But for some reason, sooner or later, you do.
22:06 < JimBuntu> dgurney, Oh, I misread... never messing up, no, not strange. I thought you had said 'never messing with'
22:06 < Dagmar> Okay, if the set is all people rather than just the people who've tried to use dd
22:06 < Manis> OK. It's really unfortunate that seek and skip have such a similar name.
22:06 < koala_man> I like being a pedantic jerk
22:07 < za1b1tsu> can you have accureate temperature monitors if you are running linux in a virtual machine?
22:07 < Acheron-a> https://stratechery.com/2018/the-end-of-windows/
22:07 < bobdobbs> just out of curiousity... does anyone here use linux video editing tools? I've just started playing around with flowblade.
22:07 < JimBuntu> za1b1tsu, sure. No idea what temp you are measuring or with what... but yes, you can have accuracy in a VM.
22:08 < Dagmar> bobdobbs: That depends.  How fluent are you in obscenity?
22:08 < koala_man> ten years ago, kdenlive was the editor with the best features-to-crash ratio
22:08 < hexnewbie> Ah, I also misread that. Yes, if one reads it as ‘data destroyer’ every time they use it, gigantic failures are usually averted. You don't dance around a chainsaw.
22:08 < Dagmar> ^-- note the use of the phrase "features-to-crash"
22:08 < koala_man> it had plenty of features and only crashed every 15 minutes or so
22:08 < za1b1tsu> JimBuntu: I'm using the temperature monitor in the lxpanel (lubuntu, lxde desktop). Do you have a recommandation?
22:08 < Dagmar> I used to literally boot a freakin' rastafarian distro just because it had a stable build of cinelerra
22:09 < Dagmar> Video editing under basically anything you didn't pay a lot of money for is a PITA
22:09 < Manis> Since we seem to have so many dd experts here, let me ask the thing that I really don't understand anymore. So let's say the original file was 32GB (lvm2 PV with ~16GB LVs on it), I tried to extend it after 800MB I notice that I used the wrong option. Why is my file now 16GB?
22:09 < bobdobbs> Dagmar: oh, I use linux. I'm deeply fluent in obscenity. positively shakespearian.
22:09 < Manis> Is it because the VG was still active, then something wrote, extending the file to 16GB?
22:09 < JimBuntu> za1b1tsu, I take it that you are wanting to know MB/CPU/RAM type temps? I don't have any suggestions for those as I don't normally look at them graphically.
22:09 < Dagmar> bobdobbs: Youre going to need it
22:10 < bobdobbs> Dagmar: mind you, one could replace 'linux' in my last statement with any OS really
22:10 < Dagmar> Manis: You tried to extend your PV with _dd_?
22:10 < Manis> Dagmar: Yeah, PV is a loopback device.
22:11 < za1b1tsu> JimBuntu: yeah, cpu temperature, memory usage. I see thank you
22:11 < JimBuntu> Manis, depends on the command you used. I'm betting that you overwrote the file, so it was basically negated to 0 bytes at the start... after a while, before you noticed, it had grown to 16GB.
22:11 < Dagmar> Manis: Probably using dd at all there was needless.  All you needed to do was append some zeros.  You could have done that with cat
22:11 < bobdobbs> Dagmar: I've also got a mac, upon which I've installed Final Cut Pro. And I'll learn that eventually. But I wanted to play around with something on my linux machine, cos I use it more often and enjoy it more. And I wanted to experiment with something lighter in features.
22:12 < Manis> Dagmar: Or dd if=/dev/zero >>
22:12 < bobdobbs> Dagmar: I've experimented with Openshot in the past. But I found it impossible to line up video and audio tracks with any precision
22:12 < xse_> Hi, I have a deamon launched with seccomp filters, i'm guessing that every process this deamon run gets the same restrictions, what happens if this deamon launches another program using seccomp ? like to my understanding every syscalls made by the deamon are filter and examined, but does the syscalls made by the process launched by the deamon gets filtered twice ?
22:12 < Manis> JimBuntu: But why 16GB?
22:12 < Dagmar> bobdobbs: Well, kdenlive isn't bad.  Cinelerra isn't bad.  Avidemux isn't bad.  No wait... It's kind of horrible, but it's only marginally more horrible than everything else
22:12 < Manis> Also there's still data on the PV.
22:13 < Dagmar> bobdobbs: The big stinky is that ffmpeg is a life-sucking desert of shifting sands that many things depend on and the thing being constantly in flux doesn't help
22:13 < JimBuntu> Manis, I don't know why 16GB... when using dd, the file is growing over time, it depends on when you stopped it and what command you used
22:13 < spammcoin> xse_: yeah it will check both filters, unless the first filter prevents additional filters
22:14 < bobdobbs> Dagmar: I see
22:14 < Manis> JimBuntu: Command is "dd if=/dev/zero of=/var/pv status=progress bs=1M skip=32768 count=10240", I stopped it at 850MB.
22:14 < Dagmar> bobdobbs: I suggest having mulitple options installed and figure out through pain and suffering which one is the least unreliable for whatever editing task you are currently attempting
22:14 < xse_> spammcoin: thanks a lot !
22:14 < hexnewbie> Blender crashes?
22:15 < Dagmar> Manis: You _really_ need to read the man page bits for _every_ option you attempt to use with dd
22:16 < Dagmar> Manis: skip makes it skip that many bytes forward in the file it's reading _from_
22:16 < Manis> Dagmar: True that.
22:16 < Manis> Dagmar: I know that by now :-( The question is whether the rest of the file is still there. I could live without the first 900MB.
22:17 < Dagmar> hexnewbie: Not often, but I can see why a few hours with some of these video editing tools might inspire someone to think that simply drawing, keyframing, and compisiting the entire thing over in a virtual CAD system would be easier
22:17 < JimBuntu> Manis, I would have expected that to create a 10GB file.
22:17 < autopsy> Am I banned?
22:17 < JimBuntu> autopsy, from where?
22:18 < dgurney> you are banned from life
22:18 < Manis> JimBuntu: Now I would expect so too.
22:18 < autopsy> JimBuntu, don't know said my nickname was liveuser after a disconnect from freenode then I got disconnected again after I identified said I was banned cannot send to channel.
22:18 < Manis> But the file is neither 10GB not 850MB.
22:19 < bobdobbs> Dagmar: are there any packages that you'd recommend in particular ?
22:19 < Dagmar> bobdobbs: We've mentioned them actually
22:19 < bls> autopsy: if your client auto-reconnects using a made up username, you get locked out of channels that require registration until you switch back and identify
22:19 < Dagmar> bobdobbs: There's fewer than five you'd ever want to deal with right now
22:20 < autopsy> bls yeah it reconnected me but with a wrong username maybe autopsy was still in use on Freenode I don't know how that is happenning.
22:20 < bobdobbs> heh... I'm glad the cinelerra website is honest: "There is a fairly obselete user manual..."
22:20 < autopsy> It only happenned once though.
22:20 < hexnewbie> autopsy: I think that Freenode's SASL identifies you with your real nick and let's you even if you're using your unregistered alt (I could be wrong)
22:20 < bls> autopsy: #freenode would know more about the mechanisms though
22:21 < hexnewbie> autopsy: So if your client supports that, it might be the better option
22:21 < autopsy> hexnewbie, hexchat is taking too long to identify for me when it reconnects.
22:21 < Dagmar> Use the SASL option to connect
22:22 < autopsy> hexnewbie, so I get forwarded to another channel and then it identifies
22:22 < autopsy> I don't know weak wireless signal I guess.
22:22 < sammyg> autopsy, hi! did you manage to make that bootable windows install media?
22:22 < hexnewbie> autopsy: Yes, which is why I (and Dagmar) recommended SASL option, which identifies you during the connection and before you have joined any channels. It will work as long as services are online (even with your alt nick)
22:23 < autopsy> sammyg, no I lost all my partitions all I have is a LiveDVD of Fedora 27 running now.
22:23 < sammyg> oh no :o
22:23 < sammyg> i hope you had backup
22:24 < uplime> autopsy: http://freenode.net/kb/answer/sasl
22:24 < autopsy> hexnewbie, it is not working with my alternative nickname as liveuser apparently but I am using SASL.
22:24 < uplime> autopsy: if you were using sasl you would be authenticated no matter what nick you use
22:24 < autopsy> sammyg, nah I had no backups.
22:24 < autopsy> uplime, maybe I'm confused then I can identify using a wrong nickname?
22:24 < sammyg> OH NO :O
22:24 < sammyg> :)
22:25 < sammyg> sorry about that man
22:25 < uplime> autopsy: yes. the nickname you use is separate from yousr username
22:25 < autopsy> uplime, ahhh you mean cause it asks for username and password in the SASL dialog.
22:25 < uplime> exactly
22:26 < uplime> for example, in znc my nickname is uplime, but my username is nchambers (well it would be if I use sasl plain)
22:26 < autopsy> Then something with a latent connection is keeping me connected on Freenode's connection list while I'm disconnected then.
22:27 < autopsy> Cause it switched it to liveuser which I am not.
22:28 < autopsy> uplime, yeah I think I'm confused then.
22:28 < uplime> hi confused im uplime
22:28 < autopsy> It has never happenned before though just once right now when I asked if I was banned.
22:29 < CashDash123> How would Fallout New Vegas preform under wine 2.0.4?
22:29 < CashDash123> modded hopefully
22:30 < ayecee> try it and see, i guess
22:30 < ayecee> maybe check the winedb
22:34 < dunnousernamefn> Is there a tool to compile an OpenCL kernel, maybe load some stuff into memory, execute and show the results? I don't want to debug my loading code yet
22:47 < VjdfMQ> hey all
22:47 < VjdfMQ> Is it possible to run tcpflow to get only output or input data ?
22:47 < VjdfMQ> To separate them
22:52 < noway96> So it worked hexnewbie
22:53 < noway96> Are microcenter USBs better for bootable USB uses? I don't get the segfault if I use microcenter USBs but if I use Cruzer or some custom USB it crashes
22:56 < cahoots> hi, if i'm running "myVar = true; sem_wait(...);", and i want to guarantee that myVar will be set before sem_wait is run, do i need both asm volatile("": : :"memory") as well as __sync_synchronize?
22:56 < cahoots> in C
22:57 < autopsy> noway96, I had a Cruzer SanDisk that was booting Fedora 27 recently till I erased it.
22:57 < koala_man> cahoots: it's not off topic, but you may have more luck in ##c. we're better at questions like "is xubuntu better than lubuntu?"
22:57 < noway96> autopsy, it boots, but some program in it segfaults
22:58 < Bashing-om> noway96: "check disk for defects' passes ?
22:58 < autopsy> noway96, it seg faults when during boot strap? During start up?
22:58 < cahoots> koala_man, true
22:58 < noway96> no during normal operation
22:58 < noway96> after login
22:59 < GautamS> Hey all
22:59 < autopsy> noway96, you can use strace program to do a system trace and see where it is segmentation faulting on the terminal.
22:59 < GautamS> I'm looking for a linux distribution that executes programs like DOS did. I know it's kinda difficult since all programs use the X window system in some way or another, but I'm hoping something like this has been done before.
22:59 < autopsy> noway96, it seg faults but you don't know what it is?
23:00 < lupine> >  all programs use the X window system in some way or another
23:00 < lupine> well, they don't
23:00 < GautamS> I meant to say graphical applications, sorry
23:00 < lupine> just take a random distro, systemctl stop gdm3 (or whatever), go
23:00 < GautamS> For example, the virtual console provided under Debian distributions fail to execute something like glxgears
23:00 < hexnewbie> GautamS: You won't graphical, non-X programs? Why?
23:00 < uplime> autopsy: my program was segfaulting the other day if I passed it a string with a length of 20, but every other size was fine :C
23:00 < lupine> consider elinks with svgalib for instance
23:00 < uplime> GautamS: not all programs use the x window system
23:01 < uplime> you could be using wayland
23:01 < koala_man> GautamS: you want to run graphical programs without X?
23:01 < GautamS> Like under DOS, when you execute something like DOOM, it completely takes over the screen
23:01 < hexnewbie> GautamS: You want fullscreen programs?
23:01 < GautamS> Yes, fullscreen graphical programs executed from a terminal
23:01 < autopsy> uplime, I would use strace to trace it's execution.
23:01 < lupine> GautamS: right, you want svgalib, sdl + directfb, etc
23:01 < lupine> it's totally a thing
23:01 < hexnewbie> GautamS: Programs support F11, Alt+F11, Ctrl+Shift+F and other shortcuts to go fullscreen.
23:01 < uplime> autopsy: it won't do any good
23:02 < uplime> (and strace isn't a segfault tool)
23:02 < koala_man> GautamS: you can do that with directfb and svgalib. SDL based games can often be made to use it
23:02 < autopsy> uplime, why is that?
23:02 < GautamS> hexnewbie: I don't want to do that. I just want a minimal system being able to run a few games
23:02 < uplime> autopsy: well A, I already figured it out, and B, I already knew where it was segfaulting, and C, gdb is better for that
23:02 < GautamS> I have difficulty trying to explain this, but..
23:03 < lupine> just like DOS, it won't be well-accelerated and you're responsible for every pixel
23:03 < uplime> strace wouldn't tell me why it was segfaulting
23:03 < autopsy> uplime, I am not sure how to use gdb
23:03 < hexnewbie> GautamS: Which specific games?
23:03 < noway96> Bashing-om, I used Gparted to set a new partition table and then a new partition with format
23:03 < hexnewbie> lupine: You could have Glide in DOS. Or anything, really, since the program could ship drivers for anything.
23:03 < GautamS> hexnewbie: Nothing specific, stuff that uses SDL/GL
23:03 < GautamS> Most games would do that
23:03 < noway96> autopsy, I know which program segfaults. It's a browser that takes over an X11 session. But I'm not sure why it segfaults.
23:03 < hexnewbie> GautamS: Do the games work without X, and why is not having X a requirement really?
23:04 < GautamS> I should clarify that. I don't want to remove X, I just don't want a window system
23:04 < koala_man> for nostalgia purposes?
23:04 < GautamS> yess
23:04 < GautamS> you got it :D
23:04 < noway96> I just got a core dump though so let's see what I find
23:04 < hexnewbie> GautamS: I'm not sure you'd achieve fullscreen without a window manager
23:04 < GautamS> Like I want to type in DOOM, or glxgears and see my entire screen filled with that
23:05 < koala_man> GautamS: you definitely can. you can also run dosbox or something in fullscreen to play real dos games
23:05 < hexnewbie> GautamS: matchbox-window-manager may do what you want, though
23:05 < koala_man> yes, there are also X11 wms that will show every program fullscreen
23:05 < autopsy> noway96, a browser that takes over an X11 session? What is that?
23:05 < noway96> Qt5WebKit
23:06 < GautamS> hexnewbie: Yes, matchbox is what I want
23:06 < GautamS> Just if I could now have a terminal + matchbox
23:06 < autopsy> noway96, maybe the disk is corrupted. Small amounts of corruption could do that.
23:06 < hexnewbie> GautamS: Matchbox can only display a single program fullscreen (or nearly fullscreen if a panel exists). From what I can remember from when I used it on my older phone
23:09  * Psi-Jack hands GautamS a box of matches.
23:10 < GautamS> man, I could have a lightweight linux distro and make it run dosbox fullscreen on startup
23:10 < GautamS> but that.. wouldn't be satisfying
23:11 < Psi-Jack> I have a virtual machine host server running Linux, running a virtual machine of Linux, running my BBS software, which runs DOSEMU to run door games.
23:11 < lupine> for a while I ran a VM solely for df
23:11 < lupine> I'd connect to it over SSH to play
23:11 < koala_man> GautamS: you can add a grub entry that boots real DOS
23:12 < Psi-Jack> lupine: df? Disk Free? Seems boring.
23:12 < lupine> we all need a hoppy
23:12 < lupine> hobby*
23:13 < Psi-Jack> Could've set that up over a socket, xinetd or systemd sockets, so all you'd need to do is netcat it. :)
23:14 < jim> a hoppy hobby?!
23:18 < rockdarko> I can get evolution to launch no problem, but the second I install evolution-ews, it won't launch anymore and crashes with a seg fault. Info pulled from journalctl | grep evolution: https://darko.vision/pub/evolution01
23:20 < WalterPeck> what do you guys use for wireframing ideas?
23:20 < phogg> bubblegum and bailing wire in meatspace, like a real man
23:20 < Psi-Jack> rockdarko: it's trying to give you a sign that exchange si bad.
23:20 < phogg> s/bailing/baling/
23:20 < Psi-Jack> WalterPeck: I use wire.
23:21 < rockdarko> Psi-Jack: I already know that, but that's work e-mail. and oddly enough it works on my personal laptop setup.
23:21 < jim> WalterPeck, in your world, what form does a wireframe take?
23:22 < WalterPeck> Psi-Jack: thanks!
23:22 < MrElendig> rockdarko: drop the grep
23:22 < MrElendig> rockdarko: also you want -b1
23:22 < phogg> WalterPeck: In all seriousness I use a whiteboard, or kolourpaint. But I don't need anything permanent or for sharing with people outside of one room.
23:23 < rockdarko> MrElendig: I'm getting used to journalctl - please bare with me, thanks for the help :)
23:24 < Psi-Jack> rockdarko: Fun.. sig11 segfaulting.
23:24 < WalterPeck> phogg: thank you
23:24 < MrElendig> rockdarko: the "don't grep" is universal, grepping often hides the real interesting bits
23:24 < rockdarko> Psi-Jack: Does it mean I have herpes?
23:24 < Psi-Jack> rockdarko: There is a possible chance of such meanings.
23:25 < rockdarko> MrElendig: Yeah, I guess my output omits all the lines that are relevant and just don't have evolution in em, thats dumb. I just dont know better - now I do thx.
23:26 < rockdarko> so sorry to come so unprepared, but that -b1 thing - it's an option to journalctl?
23:26 < Psi-Jack> rockdarko: We'll have to submit you to quarantine for further studies, anal probing for the aliums, and such.
23:28 < rockdarko> Psi-Jack: My 4 anuses are eagerly waiting! haha. But seriously, sig11, does that point to anything at all?
23:29 < Psi-Jack> rockdarko: Corruption of sorts, often times. Could even mean hardware issues.
23:29 < Psi-Jack> rockdarko: What distro is this?
23:29 < Psi-Jack> And, can't your work just provide you IMAP like sane people? ;)
23:30  * Psi-Jack pets his company for actually running their own postfix+dovecot servers. :)
23:31 < rockdarko> Psi-Jack: Mnajaro, all up to date.
23:31  * ayecee is glad to have outsourced that headache :)
23:31 < rockdarko> I have the same install and the same packages on 3 systems and it's the only one giving me issues.
23:32  * Psi-Jack cringes.
23:33 < Psi-Jack> rockdarko: Well, there's your problem. A crap distro. ;)
23:34 < rockdarko> Let's not get into that distro war now :P
23:34 < ayecee> Psi-Jack _is_ the distro war >:)
23:34 < morf> :))) and don't mention manajaro in front of him :)
23:34  * Psi-Jack gets out some napalm.
23:34 < Li> what is the user's primary group and how does usermod -g groupname username differ from usermod -a -G groupname username
23:34  * rockdarko retreats in panic.
23:35 < Li> my lanugage skills fucks when it comes to man pages
23:35 < ayecee> Li: their primary group is the group they're in according to /etc/passwd. it's the group used when creating files.
23:35 < Psi-Jack> Li: Kindly mind the language, please.
23:35 < MrElendig> Li: primary group is the one that gets used when you eg create a new file or whatever
23:35 < ayecee> you type too slow
23:35 < rockdarko> I'm also using KDE, just in case you really want to hate me, here's all the ammo you need.
23:36  * rockdarko is a KDE fan boi.
23:36 < Psi-Jack> rockdarko: I used KDE since pre KDE 1.0.0. So can't fault you there.
23:36 < ayecee> pfft. KDE is too banal to bash.
23:36 < Psi-Jack> Only that current KDE sucks. :)
23:36 < jim> Li, so, man pages are hard to understand?
23:36 < rockdarko> Psi-Jack: what's your biggest beef with today's KDE? curious here.
23:37  * rockdarko looks up what KDE 1.0.0 looked like.
23:37 < Psi-Jack> rockdarko: Instability, broken widgets constantly, and "activities" vs "desktops".
23:37 < phogg> rockdarko: It looked pretty great for the time.
23:37 < jonascj> I'm fooling around with diceware / passphrases from wordlists and for the fun of it thinking how simple one could generate such passphrases from a shell script. So far "od -v -An -N1 -tu1 < /dev/urandom" can give me 8bit unsigned integers uniformly distributed (0-255), but what I need is either uniform between 1-7776 or 1-6.
23:38 < jonascj> Any better ideas than transforming the 0-255 integers to the range I need using floating point arithmetics with 'bc'?
23:38 < Psi-Jack> When taskbar buttons just randomly start blinking and worse, flickering, and becoming a huge nuisance, and the only resolution to it is logging out and back in. That's unacceptabel.
23:38 < Li> thanks ayecee MrElendig ... sure Psi-Jack
23:38 < Li> please ecuse my irc fart
23:39 < Psi-Jack> wut?
23:39 < jim> do the kde people put their stuff under git?
23:39 < Li> nm
23:39 < Psi-Jack> NetworkManager?
23:39 < hexnewbie> Dunno, with the new KDE I have whole *windows* flickering
23:39 < Psi-Jack> jim: I believe they run their own git server, yes.
23:39 < Psi-Jack> hexnewbie: Yep. That too.
23:40 < Psi-Jack> Not as frequently as the taskbar icons/buttons flickering out of control, but it happens.
23:40 < jim> ok... so I guess people can post problem reports to them? or do they keep them private?
23:40 < Psi-Jack> Ever since I swtched to XFCE4, replacing xfwm4 with i3, I've never had stability issues, and barely having to restart anything.
23:41 < Psi-Jack> jim: They have a bug reporting system.
23:41 < jim> ok
23:41 < hexnewbie> jim: I have reported like a dozen KDE bugs 10 years ago, 2 got fixed after 10 years, 8 I still receive emails with no fix
23:41 < Psi-Jack> Yeah.
23:42 < Psi-Jack> They seem to be more focused on new things, instead of fixing the broken things.
23:42 < jim> hmm, I guess it could be they;re not paying attention
23:42 < Psi-Jack> Of course, not paying attention is really bad for such a huge project. :)
23:42 < rockdarko> phogg: it really did look good actually (kde 1.0.0). I started with early KDE 2.something. That's like 18 years ago. Time flies, holy crap.
23:42 < phogg> I will once again mention e16: stable and lightweight as only software that has not changed noticeably in over 15 years can be.
23:43 < Psi-Jack> Heh. KDE 1.x, and KDE 2.x were freaking awesome.
23:43 < phogg> rockdarko: My first KDE was 1.2, as I recall.
23:43 < phogg> interestingly 1.0 came about almost exactly one month after win98
23:43  * crabmelt just waits out the showstopping bugs "This was fixed, but regressed when the changes were accidentally dropped after SDDM 0.17 was introduced into the archive." https://lubuntu.me/this-week-in-lubuntu-development-1/
23:43 < hexnewbie> 3.x was good when it stopped crashing (which was around the time it got discontinued)
23:44 < Psi-Jack> KDE 3.x, IIRC, was a freak of disasters.
23:44 < Psi-Jack> Heh yeah, seems I remember correctly. :)
23:44 < crabmelt> lotsa bugs to wait out with kde tho
23:44 < rockdarko> kde 1.2 I think: http://ymusk.sourceforge.net/screenshots/tempest-1.gif
23:44 < phogg> say what you like against kde4 but at least they finally dropped artsd.
23:44 < Psi-Jack> KDE 4 was a disaster, because they put out 4.0.0, and it was pre-alpha. Version numbering failure.
23:45 < jim> you say you're using i3 as the wm for xfce... what's the useful things about having xfce in addition to i3?
23:45 < phogg> rockdarko: looks about right, but super compressed!
23:45 < Psi-Jack> jim: The xfce4-panel, mostly. Session management is there, some key bindings are managed by XFCE instead of by i3.
23:46 < phogg> xfce has some pretty decent utility apps for configuring things, and they play nicely with software which expects GNOME
23:46 < Psi-Jack> xfce4-session handles my startup apps of system-tray apps,w hile i3's config loads in my pre-layout designed workspaces.
23:46 < crabmelt> thunar, mousepad, ristretto, xfburn, xfce4-screenshooter
23:46 < Psi-Jack> mousepad has some issues at times, so I stopped using it.
23:47 < Psi-Jack> Seems when you run multiple mousepad instances, if one crashes, they all crash together.
23:47 < crabmelt> ive custom compiled my own so i can run it as root without the nag banners
23:47 < Psi-Jack> This did not float well with me. :)
23:47 < phogg> Psi-Jack: tried leafpad?
23:47 < rockdarko> I just remember doing as much in command line as possible. When I discovered you could play music on a computer remotly via ssh (with mocp) and download p2p music (with giFTcurs) it was over for Windows. THEN I discovered DE's and fell in love with KDE. The mix of both is ultimate.
23:47 < Psi-Jack> phogg: Hmm.. May've been leafpad that did that, I know one of the two did. :)
23:48 < jim> so i3 is running "inside" the panel?
23:48 < phogg> Psi-Jack: I started using leafpad for gtk2 text editing after gedit got lobotomized and have not had that issue. Maybe it just hates you.
23:49 < jim> li, so, reading man pages is a skill, and you have to practice reading to keep it up
23:50 < Psi-Jack> jim: No, i3wm supports these things called i3-layouts, which are definition files that bind windows to i3s' window-frames. So with this, I load up my browser on workspace 1, email client on workspace 2, in a tiled workspace 8, load up Rambox and Pidgin tabbed together, and below that my Hexchat client. And finally on workspace 6, my gnome-terminal.
23:50  * phogg checks out this mousepad business
23:50 < phogg> oh yeah, it's aggressively single instanced
23:50 < Psi-Jack> phogg: heh. Must've been mousepad that I hated then. :)
23:51 < Psi-Jack> I know when it failed, it was HORRIBLE, and I used it for quick notes, often. Right now, I use gedit for such things.
23:51 < Psi-Jack> Course, back when I Used actual XFCE, I was in a windowed environment, instead of a tiled environment. :)
23:51 < crabmelt> ill admit when i need a 2nd wordwrap editor i fire up beaver. mousepad isnt particularly highperformance
23:52 < Psi-Jack> crabmelt: Does your girlfriend/wife know about this? ;)
23:52 < phogg> when I need a quick buffer for notes it's nano
23:52 < Psi-Jack> phogg: Compsoe email a lot randomly? ;)
23:53 < registeringIsBad> Hey does anyone here know how to fix overscan with xrandr? I've been tinkering with it for a few hours and still cant get it to work.
23:53 < phogg> Psi-Jack: todo lists mostly. I hear you can get dedicated software for that but it's all so clunky.
23:54 < Psi-Jack> phogg: So you use nano to compose email to yourself to take notes and send with alpine? ;)
23:54 < phogg> Psi-Jack: no, I use nano to take notes which remain sitting in its unsaved buffer until I don't need them any more
23:54 < Psi-Jack> But, nano is a mail composer. :0
23:54 < phogg> Psi-Jack: no, pico is a mail composer
23:54  * Psi-Jack grins.
23:54 < Psi-Jack> nano is too. :)
23:55 < phogg> nano is just a pico drop in replacement
23:55 < Psi-Jack> nano is what pico is, differently licensed.
23:55 < phogg> and anyway real men use elm
23:56 < TJ-> do real men suffer Dutch Elm disease too?
23:56 < Psi-Jack> Anyway, all swords sharpened. Time to leave the grind stone for the day. :)
23:56 < phogg> which would be easier if you could still get a working elm
23:58 < registeringIsBad> Does anyone here know how to use xrandr?
23:58 < stefmorino> I do
23:59 < ksk> registeringIsBad: better ask your question, dont ask to ask.
23:59 < registeringIsBad> stefmorino any idea how to fix overscan? I've tried using --scale and --transform, but all that does is zoom in and out, and there is still some things that dont show up on the screen
23:59 < registeringIsBad> ksk i already asked my question, but no one responded, so I asked if anyone knew about the topic to get someone to respond
