00:30 < spaces> I'm drunk :P
00:31 < spaces> and I need to pee :P
01:03 < banisterfiend> hi, when i use 'ifconfig' normally the interfaces have ONE ip address
01:03 < banisterfiend> but i did 'ifconfig utun1' and it returns something weird
01:03 < banisterfiend> inet 10.44.10.6 --> 10.44.10.5 netmask 0xffffffff
01:03 < banisterfiend> why does that syntax mean? and why is it more tha one ip?
01:07 < tds> that sounds like a point to point tunnel, with the local and then remote ip
01:07 < tds> the output of "ip a" may be slightly clearer for that iirc
01:07 < tds> and you should probably be using ip rather than ifconfig now anyway :)
01:11 < abdulhakeem> I have my USB only printer installed on my local Ubuntu server and Shared. How do I know install it on my linux and windows clients?
01:11 < banisterfiend> tds i'm on osx sorry
01:12 < tds> ah right, either way that sounds like a point to point link
01:12 < banisterfiend> how do i get netstat to show tcp information for oly the localhost?
01:12 < banisterfiend> tds interesting, thanks
01:12 < tds> effectively like having a /32 ip and then a /32 on-link route to the remote side
01:12 < banisterfiend> tcp socket info for only the localhost*
01:13 < banisterfiend> tds where can i read more about that?
03:00 < scientes> ahhhh scaleway server when you don't have an ipv4 address have no ipv4 connectivity
03:01 < scientes> also you can't reach other servers at the same datacenter by their public ip addresses
03:51 < spaces> Smeef don't try to hide :P
05:43 < h0dgep0dge> does anyone know anything about configuring mod_mb on apache?
07:06 < screwsss> how do i make a hostmask like this -> [14:52] Matreya is ~matreya@unaffiliated/matreya
07:08 < Peng_> Go to #freenode and ask them to give you a cloak.
07:16 < screwsss> cheerks
07:37 < abdulhakeem> Anyone willing to help me troubleshoot my shared printer? https://www.reddit.com/r/HomeNetworking/comments/8wqys2/sharing_a_usbonly_printer_via_ubuntu_server/
07:39 < jimbo> stop printing, its 2018
07:39 < jimbo> :)
07:40 < abdulhakeem> but that doesn't help me learn now does it :P
07:40 < abdulhakeem> Sometimes in life you gotta print stuff
07:41 < Mead> sometimes a tree must die so you can print out that coupon for red lobster
07:44 < abdulhakeem> Usually it's government papers I need, or coloring pages for the kiddo
07:45 < abdulhakeem> plus in the enterprise world I'm going to need to know how to deal with this, might as well practice at home ;)
07:48 < Mead> anyone have logs for the channel going back 24 hours?  I need to know when my server that runs ZNC failed, so can anyone find the last time my nick timed out?
07:58 < abdulhakeem> if a printer is USB only and doesn't have an actual network interface, can it even be shared over the network? it seems like every article I can find assumes the printer has an IP address. but since it's USB only and connected to my server, I'm pretty sure there's no IP address
07:58 < abdulhakeem> so how do I point to it?
08:01 < rewt> abdulhakeem, you set the server to share it over the network
08:02 < abdulhakeem> I have
08:02 < Go-Daniel> You need to setup sharing of that printer so its available to the network its called (network shares)
08:02 < abdulhakeem> At least I think I have
08:02 < abdulhakeem> in CUPS the printer is set to Shared
08:02 < rewt> use the ip address of the server to connect to it
08:03 < abdulhakeem> and I've edited Samba and CUPS config to supposedly allow CUPS to function as the Print server and share printers
08:04 < abdulhakeem> rewt: that's it? Don't I need a port number or something?
08:04 < abdulhakeem> or just literally the server IP by itself?
08:04 < abdulhakeem> I have a linux laptop that I'm trying to install the shared printer on via CUPS
08:04 < abdulhakeem> but I can't figure out how to actually point CUPS on my laptop to the printer connected to the server
08:05 < abdulhakeem> idk if it's ipp, http, lpd, etc
08:06 < Go-Daniel> First you need to see the printer on the network before it can have access to it
08:06 < abdulhakeem> but how? that's my question
08:07 < abdulhakeem> the printer doesn't have it's own IP address it's USB only
08:07 < abdulhakeem> in CUPS on the server, the printer is set as Shared, but nothing can actually see it
08:07 < abdulhakeem> so I think I must be missing a step or two somewhere
08:08 < abdulhakeem> and I've configured Samba and CUPS as per the support articles here: b\=gwT[n2_q=_r-A
08:08 < abdulhakeem> oops
08:08 < abdulhakeem> https://www.reddit.com/r/HomeNetworking/comments/8wqys2/sharing_a_usbonly_printer_via_ubuntu_server/
08:20 < Go-Daniel> Have you set Cups to listen to an actual IP that isn't loopback or an adapter
08:22 < Go-Daniel> By default on Ubuntu, the CUPS server installation listens only on the loopback interface at IP address 127.0.0.1. In order to instruct the CUPS server to listen on an actual network adapter's IP address, you must specify either a hostname, the IP address, or optionally, an IP address/port pairing via the addition of a Listen directive. For example, if your CUPS server resides on a local network at the IP address 192.168.1
08:22 < Go-Daniel> Listen 127.0.0.1:631 # existing loopback Listen Listen /var/run/cups/cups.sock # existing socket Listen Listen 192.168.10.250:631 # Listen on the LAN interface, Port 631 (IPP)
08:22 < Go-Daniel> In the example above, you may comment out or remove the reference to the Loopback address (127.0.0.1) if you do not wish cupsd to listen on that interface, but would rather have it only listen on the Ethernet interfaces of the Local Area Network (LAN). To enable listening for all network interfaces for which a certain hostname is bound,
08:33 < hey2> Hey all... work in a cloud datacenter right now as a server tech, but have only been doing it for a year so I am looking to advance my knowledge/certs related to the enterprise datacenter industry... I currently have "none" - I was going to try and take my CCNA/VCP6-DCV in short notice. Anyone have any recommendations for things to read, other certs to look into, was considering braindumping Cloud+ but not sure if it is worth anything
08:42 < light> why bother getting a cert if you're going to cheat?
08:45 < Haris> hello all
08:45 < h0dgep0dge> light: what did they say to imply that they're going to cheat?
08:46 < Haris> if I have a def gw, and cisco asa as two machines direct on the Internet and my request comes in from asa, but goes out through my internet gw, would that be ok ? like I have a web server. requests to it comes inside through the asa public IP, but their responses go out from my internet gw's public IP. would that work ?
08:47 < light> h0dgep0dge: braindumping
08:48 < h0dgep0dge> light: gotcha, i'm not aware of the use of that word as a verb
08:48 < h0dgep0dge> at least in this context
09:48 < GrandApe> hi.
09:48 < GrandApe> ovh.com.  someone said they lowered their prices?  how much were they and when was that?
10:52 < mines5-mobile> Is anyone awake?
10:52 < mines5-mobile> And anyone experienced with supermicro network modules
10:56 < Apachez> what about them?
10:56 < Apachez> mostly are broadcom or intel
11:20 < mines5-mobile> Sorry for the delay, I was wondering if you'd ever heard of them but routing suddenly
11:20 < mines5-mobile> Not*
11:21 < mines5-mobile> We've been having a lot of problems with them currently
11:22 < mines5-mobile> The current issue revolves around not being able to resolve addresses
11:44 < mines5-mobile> A quick reseat fixes the issues, but it's getting about when you have 20 of these doing the same thing
11:46 < mines5-mobile> Annoying*
11:53 < skyroveRR> BLAAAAAAAAH.
13:56 < brutser> hi, i have a pretty basic network with 2 vlans with 2 switches connected - now i want to create a 3rd vlan for management purpose, that can access both switches too. is that possible?
13:56 < brutser> or should i put management on physical network?
13:56 < djph> sure, entirely possible.
13:57 < brutser> djph: ok, then i must revise my configuration, right now i cannot get it to work - is it possible the firewall can only accept 1 vlan per interface?
13:58 < djph> if it's a shitt... wait what?
13:58 < djph> how's your network laid out?
13:58 <+xand> and what hardware is it
14:00 < brutser> currently have zyxel usg60 with lan1 connected to sw1 - 2 vlans on this vlan20 and vlan50, lan2 connected to sw2 - 1 vlan on this vlan172
14:01 <+xand> errrr
14:02 < brutser> so i thought of assign p6 on usg60 for management
14:03 < brutser> vlan100 for this
14:03 < djph> you can't use a separate port for "management VLAN"
14:04 < djph> generally, on routers, "separate ports" are "separate networks".  (Although, I have to find/read the specific manual to confirm on that device -- not a zyxel guy)
14:04 <+xand> sounds like an odd setup, and the VLANs are isolated
14:05 < brutser> xand: yes but vlan172 is the home network, this is a home-office setup
14:05 < brutser> so vlan20 and 50 are dediceted to the "office"
14:05 < brutser> and vlan172 is for the wife watching tv :)
14:05 <+xand> based on your description, none of the VLANs can access each other or the router?
14:06 < djph> ah, found it ... looks like by default, the USG60 has 2x "WAN" ports, and 4x switched "LAN" ports.
14:07 < brutser> djph: yes correct
14:07 <+xand> but if you're doing VLANs you only need to use one of the LAN ports.
14:07 < brutser> xand: well i have 2 switches, one for the home network, one for the office
14:08 <+xand> so the router knows about VLANs 20, 50 and 172?
14:09 < brutser> yes
14:09 <+xand> and which switch/interface each is on?
14:10 <+xand> oh so you want the same VLAN on both switches, see
14:10 <+xand> *I see
14:10 < brutser> home: p3 zyxel vlan172 <-> switch_home
14:10 < brutser> office: p4 zyxel vlan20,vlan50 <-> switch_office
14:11 < brutser> where p1 is the wan1 connected to isp
14:11 < brutser> now i have p6 left over, which i wanted to use for management, that brought me here :)
14:12 <+xand> er what are you going to plug into p6?
14:13 < brutser> a laptop or simple desktop/console thing
14:13 < brutser> just for managing the zyxel and both the switches
14:14 <+xand> that is normally possible with routers that support VLANs... not familiar with that one
14:15 <+xand> configure the same VLAN ID on both p3 and p4 as tagged, and untagged on p6 (terminology may be different)
14:15 < brutser> ok
14:16 < brutser> well the idea was of course to secure the management part, to not have that on the home or office network
14:16 < brutser> only when needed, plug in cable and do the work
14:17 < brutser> xand: and on both swithches i need to add vlan100 also, how i configure it on the switches?
14:17 <+xand> the same way as the others...
14:18 <+xand> but you'd an IP address to it
14:18 <+xand> +add
14:20 <+xand> what switches are they
14:20 < brutser> xand: netgear
14:21 < brutser> gs716t
14:21 < brutser> i know it is probably not the best hardware
14:21 <+xand> umm probably need to set management vlan option
14:21 < brutser> yes it has the option to set the management vlan
14:22 < brutser> do i set a static ip for the switch? right now switch_office gets ip from dhcp on office_int
14:22 < brutser> but that ip i cannot reach from management vlan
14:22 < brutser> at least right now i cannot
14:24 < brutser> if i allow management to access office vlan, then i lose part of the security, so that is not what i want
14:25 < brutser> maybe im confusing things now, not sure
14:27 < brutser> p6 on zyxel i declared mgmt_int, with ip 10.0.0.1, laptop connecting there will get ip in this range
14:28 < brutser> vlan100 ip 10.2.0.1 - i don't actually understand all that well what this ip range is providing
14:30 < brutser> you can see i am confused, hope i make sense enough to see what i try to do, and possibly advise me what to do
14:53 < brutser> sorry, that's what you get with networking lol, i had no internet connection anymore
14:53 < brutser> xand: anything was said?
14:56 < brutser> djph: you still here maybe?
15:09 < brutser> sorry i keep disconnecting..
15:09 < brutser> so right now the setup is only i focus on office network -->
15:10 < brutser> zyxel p4 <--> netgear switch p16
15:12 < brutser> so switch get ip from office_int
15:12 < brutser> on switch i put vlan 20,50 and 100 tagged on p16
15:12 < brutser> and also i put management vlan = 100
15:13 < brutser> now i connect a laptop to p6 on zyxel
15:13 < brutser> but obviously i cannot reach the switch yet
15:13 < brutser> i need some help with that..
15:14 < banisterfiend> hi guys -- how do i get netstat to only show me the states of loopback tcp sockets?
15:14 < brutser> the office_int on p4 assign ip to switch 10.1.0.2
15:15 < brutser> but the management p6 is on 10.0.0.0/24 subnet
15:15 < brutser> do i need to set switch static ip in same?
15:16 < Schalla> banisterfiend, grep for 127.0.0.1?
15:16 < banisterfiend> Schalla haha, aside from doing that :)
15:18 < Schalla> I dont think netstat itself (or ss) can do that.
16:05 < Holo> dam man dont leave
16:05 < Holo> check you dam trunk
16:05 < Holo> :S
16:22 < brutser> i have set static ip on switch_office, 10.0.0.50 with gw 10.0.0.1 - this is in vlan100 ip range which i declared on router. On switch I set management vlan = 100 and tagged p16 to which the router is connected. now with this setup i thought to be able to reach switch from the router, but i can't
16:23 < brutser> switch is connected to p6 on router, which interface provide ip in range 10.2.0.0/24
16:23 < brutser> vlan100 has 10.0.0.0/26 range
16:24 < brutser> anyone can help me? if need more info, let me know.
16:31 < djph> brutser: hmm?
16:32 < djph> brutser: is p6 on the router transporting VLAN100?
16:32 < wallbroken> https://paste.pound-python.org/raw/mKM4iBylU1DPzMpsWtuW/
16:32 < dogbert2> hey djph
16:32 < brutser> yes
16:32 < djph> 'sup dogbert2 ?
16:32 < wallbroken> wat do you think is happening?
16:32 < dogbert2> not much :)
16:32 < djph> good deal
16:33 < djph> dreading work come Monday - took the last week off ... there will be so many fires :(
16:33 < wallbroken> Unable to register with SleepProxy debian.local (fe80::59aa:c12b:e172:2170:3535)
16:33 < wallbroken> <class 'dns.exception.Timeout'> The DNS operation timed out.
16:33 < wallbroken> why?
16:33 < brutser> rebooting
16:34 < djph> apparently you have DNS setup incorrectly.
16:36 < wallbroken> djph how to solve?
16:37 < brutser> djph: so i can reach the gw 10.0.0.1 - but for some reason i cannot reach 10.0.0.50 which is the static ip of the switch
16:37 < brutser> arp-scan also not find the switch
16:39 < brutser> but that makes sense right? i mean, p4 on zyxel is connected with p16 on switch - this is to provide vlan20 and vlan50, vlan100 is on mgmt int, which is on p16
16:39 < brutser> that is what i asked from the start really, i think i need to add vlan100 to office_int, as well as mgmt_int
16:40 < brutser> right?
16:41 < brutser> but i only can assign 1 base port really
16:42 < brutser> so switch_office p16 <--> zyxel p4 this is to provide the office network, with vlan20 and vlan50
16:42 < brutser> but then vlan100 is unknown right?
16:43 < wallbroken> server side: ValueError: 'fe80::59aa:c12b:e172:2170%enp0s8' does not appear to be an IPv4 or IPv6 address
16:43 < wallbroken> <Greenlet at 0x7f16fa00fd70: _handle_and_close_when_done(<bound method SleepProxyServer.handle of <SleepPro, <bound method SleepProxyServer.do_close of <SleepP, ("pk(\x00\x00\x01\x00\x00\x00\x08\x00\x01\x00\x00\)> failed with ValueError
16:49 < djph> brutser: what? no that doesn't make any sense.
16:50 < djph> brutser: the switch should respond on whatever IP is setup as management (provided, ofc, you've told the switch what its management vlan is -- otherwise it MAY be looking for untagged (VLAN1) packets with that IP)
16:50 < djph> wallbroken: because 'fe80::59aa:c12b:e172:2170%enp0s8" is not a valid ipv6 IP address.
16:51 < wallbroken> djph how to fix?
16:53 < djph> use a valid IP Address
16:54 < Dagger> "fe80::59aa:c12b:e172:2170%enp0s8" is accepted by getaddrinfo() in AI_NUMERIC mode, so it should be fine
16:54 < Dagger> i.e. I guess you'll need to patch the code to fix it
16:55 < tds> I've seen some applications with their own handling of v6 link local addresses, so yeah, probably time to start looking at the source
17:29 < wallbroken> how to diable ipv6 on debian?
17:30 < Dagger> the appropriate approach is to not disable it
17:30 < Dagger> if you're having a problem with it, fix the problem
17:32 < wallbroken> how to diable ipv6 on debian?
17:32 < wallbroken> i need it
17:32 < wallbroken> i need to force a client in ipv4
17:32 < wallbroken> but it des not have --bind
17:35 < brutser> wallbroken, can you not just sysctl disable, like i don't know exact, sysctl -w net.ipv6.conf.default.disable = 1?
17:36 < brutser> sysctl -w net.ipv6.conf.default.disable_ipv6 = 1?
17:36 < brutser> hrm something like that :)
17:37 < tds> http://howtodisableipv6.com/ :)
17:37 < brutser> :)
17:48 < obsrwr> would a linux host with net.ipv4.conf.all.proxy_arp=1 not send ARP replies about its own interfaces?
18:26 < Apachez> there are both a kernel boot param and a kernel runtime param to disable
18:27 < Apachez> ipv6.disable=1  as boot param to disable the ipv6 stack
18:32 < cluelessperson> question, how do you guys test for bottlenecks or slow performance issues?
18:32 < cluelessperson> for example, dns queries seem slow now
18:32 < cluelessperson> not sure how to troubleshoot it
18:39 < scientes> cluelessperson, dig shows you how long a dns query takes
18:41 < cluelessperson> scientes: sweet, so   example.com 63ms, google.com 6ms, network.location 3ms
18:42 < cluelessperson> and it seems its cached now
18:42 < cluelessperson> example.com 3ms
18:42 < cluelessperson> which probably means they're all cached
18:58 < skyroveRR> cluelessperson: google for "anycast DNS"
19:48 < FightingFalcon2> What would happen if i set net.core.rmem_max value very low or very high?
19:49 < rewt> what does net.core.rmem_max affect?
19:49 < FightingFalcon2> maximum socket receive buffer?
19:50 < rewt> are you using a question to answer a question?
19:51 < FightingFalcon2> yes?
19:53 < FightingFalcon2> Why are you people here so rude?
19:55 < FightingFalcon2> What does 10GE mean?
19:55 < Dalton> ten gigabit ethernet
19:55 < rewt> 1) by knowing what it affects, you should be able to figure out what its effects would be by changing it;  2) question marks are for questions; that's why they're called QUESTION marks
19:55 < Dalton> was that a rude answer?
19:56 < rewt> i'm not sure which of those you thought was rude
19:56 < FightingFalcon2> Im a newbie. I have no idea what maximum socket receive buffer means. And i add the question mark because i wasnt sure about the correct answer
19:56 < rewt> then prefix it with "i think" or something
19:57 < rewt> "being not sure" is not the same as "asking a question"
19:57 < Holo> Dalton this is mean http://lmgtfy.com/?q=What+does+10GE+mean%3F
19:57 < Holo> best part is how google displays the answer in a big ass box
19:58 < rewt> going from that description, maximum socket receive buffer probably means the maximum size of the buffer (where things get stuffed into) when receiving something on a socket
19:58 < rewt> so if you set it too small, it can't stuff a lot of things in
19:58 < FightingFalcon2> And what would happen?
19:59 < rewt> my guess is either dropping packets, or at least more calls to userspace
20:00 < asig> ... more cpu interruptions
20:01 < FightingFalcon2> Well, im running a debian server, with nginx, varnish, mysql and php-fpm. im also trying to learn stuff. However i dont want to set things like "set x y". i want to learn how to set something depending on the situtation. for example i know a little bit about mysql optimization.
20:02 < FightingFalcon2> I want to set my sysctl.conf accordingly. For example if your website has 100 concurrent connection maximum, its useless to set net.core.somaxconn to 100000
20:02 < FightingFalcon2> isnt it?
20:02 < FightingFalcon2> asig what does it have to do with the CPU?
20:03 < asig> when buffer is full, the content of the buffer bust be proceesed
20:03 < asig> s/bust/must
20:04 < FightingFalcon2> well, setting it low will cause problems, thats understood. how about setting it TOO high?
20:21 < krekurul> hi guys. The torrent client that I am using is stucked at 0%. I tried changing the port, using a vpn an even usind my mobile data.
20:21 < krekurul> Still no result
20:21 < krekurul> Is it possible to be related to firewall?
20:22 < krekurul> that's very weird
20:25 < krekurul> what could it be?
20:27 <+pppingme> have you tried other torrents?
20:29 < FightingFalcon> How do i know what value is optimal for net.core.rmem_max in my system?
20:40 < cluelessperson> krekurul: this is ##networking ...
20:41 < krekurul> aren't vpn and port related to networking?
20:42 < cluelessperson> krekurul: just because they're terms used, doesn't mean we'll help you troubleshoot your torrent software
21:24 < thatlizdude> Hi, is this the proper channel to ask about nginx?
21:25 < superkuh> It could be. There's an nginx channel too.
21:25 < thatlizdude> yeah but the activity on that is meh
21:28 < thatlizdude> anyways, sometimes when I reboot my VPS I get an error from nginx which works as a reverse proxy for a website: "[emerg] 802#802: host not found in upstream "externaldomain.com" in /etc/nginx/sites-enabled/mydomain.com:12"
21:28 < thatlizdude> it crashes my nginx server, but when I restart it manually it works fine
21:29 <+xand> might be that DNS isn't working when nginx starts
21:29 <+xand> you could put it in /etc/hosts
21:29 <+xand> or you can configure the upstream IP addresses in nginx
21:30 < thatlizdude> the externaldomain.com DNS?
21:30 < thatlizdude> I'm really not great with networking tbh
21:30 <+xand> DNS on the nginx server, meaning it can't resolve that name
21:31 < thatlizdude> oh yeah, that might be it since sometimes it does work and sometimes it doesn't
21:31 < thatlizdude> but it was doing it before too, when I was just accessing it without a DNS as a plain IPv4
21:31 <+xand> the website?
21:32 <+xand> I mean, you had that IP address configured as upstream in nginx?
21:32 < thatlizdude> I'm not really sure what "upstream IP" means so...
21:32 < thatlizdude> I don't edit stuff if I don't know what it means :D
