--- Log opened Thu May 31 00:00:38 2018 00:44 < brianx> catphish: email is set up and working end to end. even most of the spam filtering is working. :-) 00:44 <+catphish> cool 00:48 < Harlock> what spam filtering product? 00:55 < brianx> iptables. :-) 00:55 < brianx> i maintain a rather extensive blacklist. around 99% of the internet should not be sending me mail. 01:11 < FrostCyborg> Anyone here have decent experience with HP/Aruba Procurves with modules? I'm trying to figure out if using "stacking 1 flex-module remove" will cause any issues to the production of the switch if I've removed all GBICs and cables from the ports in the module. It's a stack of two 3810Ms and I'm entering a realm of middling experience. 01:15 < spaces> FrostCyborg huh ? 01:15 < spaces> explain again 01:17 < FrostCyborg> I have two 3810Ms, 16 SFP+ port models with an additional 4 SFP+ port module in one of the two module slots. It currently thinks it has the GBIC transceivers still in place even after removal and this was after a reboot. So I wanted to reseat the module, but it's not hot-swappable. You need to run the removal command first. I've never had to remove a module from any of the modular switches I've used in our environment, and I 01:17 < FrostCyborg> wanted to know if anyone else had any experience with it. I'm hoping it's just as simple as it cleanly disconnects the module and allows me to remove it. 01:18 < FrostCyborg> But since this stack contains our storage array and VM hosts I REALLY don't want to run into any gotchas. This stupid issue is already weird in of itself. 01:20 < FrostCyborg> @spaces I hope that was clearer... I apologize for not being clear in the first place. 01:21 < spaces> sec, reading 01:22 < spaces> FrostCyborg it's a a failover stack ? 01:23 < spaces> what I don't get is, is it still in or out ? 01:23 < FrostCyborg> No. It's more of a management/ease of configuration stack. The switch in of itself is fine as far as I can tell. It's one of the expansion modules that's "stuck" 01:23 < FrostCyborg> The switches have backplane stacking cables for interswitch communication 01:24 < spaces> stuck but out of of the chassis ? you removed and rebooted it ? 01:24 < spaces> I don't get it 01:24 < FrostCyborg> No, I have not removed the module. 01:24 <+catphish> that sounds horrible, i thught all those modules were hot swappable :( 01:24 < spaces> catphish they should be 01:24 < spaces> but as it's stack module.... it could be it needs it from boot 01:25 < spaces> the cisco ones are not hotswappable as well wasn't it ? 01:25 <+catphish> oh, i'm thinking of the transceivers, not the line card itself 01:25 < FrostCyborg> I apologize for not being clear... 01:25 < FrostCyborg> The stack module is not stuck 01:25 < spaces> ah 01:25 < FrostCyborg> the SFP+ expansion module is. 01:25 < spaces> ok 01:25 < spaces> no the port 01:26 < spaces> it's no module 01:26 < spaces> it's a port on a card 01:26 <+catphish> i'm not familar enough with procurve to advise, but if there's a command to remove the card, that seems sane enough 01:26 < spaces> FrostCyborg show us pics 01:28 < FrostCyborg> @catphish That's what I was hoping. Just wanted to see if anyone else dealt with this before 01:28 < FrostCyborg> spaces pics of? 01:29 < FrostCyborg> The switch? Module? both? 01:29 <+catphish> afraid my advice is worthless as i've never used a hp stack 01:29 < spaces> FrostCyborg switch, I'm not sure what expansion you mean now 01:29 * spaces did in the 4000/8000M days 01:30 < FrostCyborg> https://marketplace.hpe.com/pdp?prodNum=JL083A&country=us&locale=en&catId=329290&catlevelmulti=329290_5318692_4179423_1008605445 01:30 < FrostCyborg> This module 01:30 < spaces> FrostCyborg so that module "tells" you that it sees a gbic which is not in there 01:31 < FrostCyborg> Yes! 01:31 < spaces> aha ok, then reboot the modulefrom the commandline 01:31 < spaces> that should be possible 01:31 <+catphish> FrostCyborg: pretty poor that it didn't detect the right module after a reboot, maybe the stack master remembers 01:32 < FrostCyborg> Yeah, except this is on the stack master. @catphish 01:32 < FrostCyborg> catphish commander technically 01:32 <+catphish> FrostCyborg: well if you rebooted it, wouldn't that mean the other one beceme master in the meanatime? 01:32 <+catphish> and hence the running config would have remained 01:32 < FrostCyborg> @catphish No, in Procurve world, rebooting reboots the stack 01:33 <+catphish> oh ok 01:33 < FrostCyborg> You can technically do one at a time 01:33 <+catphish> then i have no idea :( seems like an eject command is the only option 01:33 < spaces> FrostCyborg the stack dies when you reboot the master ? 01:33 < spaces> yeah should be 01:33 < FrostCyborg> catphish That's what I was thinking... I'll just wait until later in the day in case I have "issues" 01:34 < spaces> it's not HA 01:34 < FrostCyborg> spaces No, one of the additional switches becomes the "commander" 01:34 < spaces> I have read about this about half a year ago 01:34 < FrostCyborg> But if you reboot the stack as a whole which is default behavior then you get the same commander back when they come up 01:34 < spaces> FrostCyborg then reboot the freaking thing 01:34 <+catphish> sounds like he did 01:35 < spaces> take it down 01:35 < tds> if by any chance anyone in the uk has monitoring pointed at google's resolvers, has anyone else seen an increase in latency (to both a and b resolvers) since ~5:30pm? 01:35 < spaces> FrostCyborg I think you are just afraid of the "failover" never tested before ? 01:35 <+catphish> tds: how much increase? 01:36 < spaces> tds it's because of the Brexit, hell we are gonna nail them :P 01:36 < tds> one box went from ~2ms to ~7ms 01:36 < FrostCyborg> spaces I will probably have to. I'd prefer to try the command to down the module for removal first since there are no active connections on it. 01:36 < tds> oh wait, I just remembered that ripe atlas is a thing, I'll go check there :P 01:37 < spaces> FrostCyborg it's simple, connections for storage are on both switches ? 01:37 < spaces> for each device 01:37 <+catphish> tds: i see 7ms right now, but dont know what it was before 01:37 <+catphish> frankly, 7ms is fast, so "meh" 01:38 < TandyUK2> tds: yes, just tested it here and i seem to have gone from ~7/8 to ~13/14 01:38 < TandyUK2> 2>7 is one hell of a jump 01:39 <+catphish> tds: looking at a traceroute, its going a long way :( i suspect they downed their london resolvers 01:39 < tds> yeah, I suspected that might be the case 01:39 < UncleDrax> (obligatory: brexit?!) 01:40 < tds> oh well, someone at google is probably having a far worse evening trying to fix it 01:40 < spaces> UncleDrax as I said, we are goign to nail them 01:40 <+catphish> it doesn't help that google's network has no rdns :( 01:40 < tds> yeah :/ 01:40 < spaces> huh ? why no rdns ? 01:40 < FrostCyborg> spaces Yes. I've already rebooted both switches to solve another problem. This module situation seems to have persisted through. It's really frustrating too because the config for this stack is stupid simple... VLANs, ports tagged and untagged, IPs for the switch on each VLAN, and spanning tree... It's like 40 lines long. It's literally for 10Gb for storage and VMs... 01:40 <+catphish> spaces: ask google 01:40 < FrostCyborg> all layer 2 no less, no layer 3 01:41 < spaces> catphish I just did, I'm waiting for their reply, I hope they have a long TTL 01:41 <+catphish> tds: i see this: https://paste.ubuntu.com/p/6t8MfXPwWS/ 01:41 <+catphish> tds: i can't explain why it doesn't reach 8.8.8.8, that makes no sense 01:42 < spaces> FrostCyborg so it's simple then, turn of the freaking switch, rip out the module, boot it, see what happens... turn it off again, put module back in and done 01:42 < tds> yeah, I see the same behaviour as well, yet I can ping 8.8.8.8 fine 01:42 < spaces> is about 30 min woik max 01:42 < tds> and I've seen mtr show ??? as intermediate hops before (but still show the last one), so that's just weird 01:42 < spaces> work 01:42 < spaces> I need to brush teeth 01:42 <+catphish> tds: that's very odd, i'd guess they're sending it off outside the great kingdom 01:43 < FrostCyborg> spaces LOL, that's a simple way to solve it. Thank you. 01:45 < tds> I'm sure I can get to a pretty ui showing a change in the route, but only if I can ever get the ripe atlas search page to load ;) 01:45 <+catphish> tds: looking at that route, i'd expect a responde of 2-3ms if they were resolving in london, probably just maintenance, and still impressively fast 01:46 <+catphish> also looking at that route, i feel i'm being a but hypocritical about rdns :) 01:47 < tds> heh, it's still a little bit useful like that I guess, it at least shows ownership 01:47 < tds> though so does mtr -z :P 01:47 < spaces> FrostCyborg you didn't thought about that ? 01:48 < spaces> meb my dog want to lie against my legs all the time 01:48 < spaces> meh 01:49 <+catphish> i've never seen mtr -z 01:49 < FrostCyborg> spaces I did... I just was trying to see if the other options might be preferable. The command to just tell the module to shutdown/remove seems pretty straightforward but since this is a production environment, I really was hoping maybe someone had some specific knowledge that "yeah, it's easy and won't cause problems" 01:49 < tds> shows the ASN next to each hop 01:49 < tds> can be slow to do lookups sometimes though 01:49 <+catphish> just tried it, doesn't seem to work well :( 01:50 < spaces> FrostCyborg stuck means, take out and failover 01:50 < spaces> you need a hard reset 01:50 < tds> some times it seems to work pretty much instantly, other times mtr just displays a blank screen for ages, I don't know why 01:50 < spaces> mtr is not always that reliable 01:51 <+catphish> i got a blank screen for ages, eventually it worked, but doesn't know my ASN 01:51 < spaces> it seems my laptop fan needs some new Olive oil after 1,5 year! 01:52 <+catphish> and it's a cool mystery to me why it's not getting a response from 8.8.8.8 01:52 < spaces> are they changing routes ? 01:53 <+catphish> my guess, too many hops, and it gives up 01:53 < spaces> nah doubt it 01:53 < tds> oh, from my desktop I get a load of missing hops, then a response 01:53 <+catphish> doesn't work even with -m 50 01:54 < spaces> I think they are changing routes 01:54 < spaces> or maybe even failover 01:54 <+catphish> -m 50 doesn't work, it doesn't send 50 requests :( 01:54 <+catphish> wonder when mtr "gives up" 01:54 < tds> https://pastebin.com/wwZiydix 01:55 < tds> that's what I see from my desktop, weird 01:55 < tds> oh, oops, I didn't use the raw link :( 01:56 <+catphish> eww he 01:56 <+catphish> peer with google you savage :) 01:56 < tds> heh, maybe they'll reply to my email eventually ;) 01:57 <+catphish> lol, oh we had this conversation didnt we 01:57 <+catphish> i see them via linx rs 01:57 < tds> haha, yeah 01:57 < tds> last one I got told to update my records on peeringdb (which should be up to date anyway), I suspect their automatic provisioning won't like the lack of a v4 address on the IX port entry 01:58 <+catphish> nobody likes non-dual-stack-peering 01:58 < tds> yeah, I guess I'll wait a while and see if they reply, failing that I could always add the address and just set it up not announcing anything 01:59 <+catphish> i should sleep now 01:59 <+catphish> went to sleep on the sofa in my office today, oops 02:00 * tds has finished exams now, so can have an even worse sleep schedule than normal 02:01 <+catphish> i also threw myself on the ground playing tennis today and have a bloody elbow 02:02 < tds> :( 02:02 <+catphish> thusly: https://i.imgur.com/5gS6nVr.jpg 02:04 <+catphish> i'll probably live 02:05 < spaces> or it's your bot who is responding here... 02:05 < spaces> catphish skateboarding is for teenagers 02:06 < spaces> or dogs 02:06 < tds> skateboarding and tennis are rather different, though ;) 02:07 < spaces> UK people are weird, it's or a reason they exit ;) 02:08 < spaces> *for 02:09 <+catphish> i voted to exit because i dont like coloured folk coming here, stealing my job, eating my quarter pounder with cheese 02:11 < spaces> you sound like you want to live with Trump :P 02:11 < tds> I wasn't old enough to vote, so never had a say in it 02:12 < spaces> I still love this one: xenial-updates/main amd64 linux-firmware all 1.157.19 02:12 < spaces> linux-firmware... sure, oh don't touch my hardware 02:12 <+catphish> tds: how annoying for you, well good thing us oldies were able to screw it up just in time for you to enter the workforce 02:12 < spaces> are you old then ? 02:12 <+catphish> 31 02:13 < spaces> are you like Benjamin Button ? 02:13 < spaces> damn I want to cuddle with my dog 02:13 <+catphish> and in case it's not obvious, i rather liked being in the EU, but i'm sure things will be ok 02:14 < spaces> I think there will be a lot of difficulties too 02:14 <+catphish> i've been forced to develop and apathy towards it 02:14 <+catphish> it won't really affect me 02:15 < spaces> hehe 02:16 <+catphish> except possibly to reduce my retirement income by some amount we'll never know, and make me need to fill out the occasional visa 02:17 <+catphish> tds: what exams did you just finish? i levels i assume 02:17 <+catphish> or is it too early for that 02:17 <+catphish> i forget 02:18 < tds> 1st year uni exams, I don't think a levels/gcses start for another few weeks iirc 02:18 <+catphish> i remember the day i finished a levels and realised i'd never have to go to school again, best thing ever 02:19 <+catphish> not that i went to school for much of my final year anyway 02:20 < tds> I quite enjoyed a levels, this year has been pretty boring though in terms of subject content 02:20 <+catphish> i didn't go to university 02:21 <+catphish> realised at the end of a levels that school just wasnt for me 02:21 < tds> lots of interesting people and technical societies doing cool things, the actual subject seems boring though so far :/ 02:21 <+catphish> yeah sounds fun, but screw the cost 02:22 < tds> yeah :/ 02:22 <+catphish> £27,000 minimum, no way 02:22 <+catphish> although it was a lot less when i would have gone 02:22 <+catphish> but still not for me 02:23 < tds> that reminds me, I still need to post off a thing to student finance that's been sitting on my desk for 2 months, I should probably do that 02:23 <+catphish> lol 02:26 < spaces> FrostCyborg fixed ? 02:26 <+catphish> good buy for now 02:26 <+catphish> zzzz 02:26 < spaces> cu 02:28 < FrostCyborg> spaces Nope, I need to wait until a little later after normal biz hours 02:59 < spaces> FrostCyborg screw those hours, it could go wrong realtime as well 03:02 < spaces> and it should not go wrong, you have failover 03:08 < tds> looks like google dns is alive again in london, I'm seeing <1ms rtt again now 03:09 < tds> interestingly, both times the routing switched, some of my monitors for nat64 (which does lookups against 8.8.8.8 through nat64) went off 03:12 < spaces> tds weird 03:14 < spaces> tds check the route again 03:14 < spaces> tds and why don't you cache your DNS lookups ? 03:15 < tds> I do, I don't use google's resolvers myself, I run my own internally 03:15 < tds> 8.8.8.8 is just a nice target for ping monitoring 03:15 < tds> lol, routing looks like it's changed back again 03:17 < spaces> tds didn't I say ? 03:17 < blocky> does anyone know what linux (arch) is supposed to do when it receives an ICMP redirect? is there a flag somewhere that i can enable to get it to add a route to the routing table? 03:17 < spaces> some people say it's not good to use google dns servers for ping monioring, use root DNS servers instead 03:18 < tds> hmm, I'd be interested to know how much icmp traffic google gets to their resolvers 03:19 < spaces> tds there are lots of cache servers in front of them ;) 03:20 < spaces> I have serious sleep issues atm 03:22 < tds> this routing is all over the place, rtt dropped for maybe 20s and then went back up again 03:23 < spaces> ok, this woman is seriously bloody :P https://github.com/BloodyHel 03:23 < spaces> or hell 03:57 < blocky> can someone suggest a good resource on how to design a vpn? installing the software is not as hard as figuring out which subnets should be used for what and how the routing tables should look 04:05 < blocky> is there such a thing as a book on architecting ip networks? 04:26 <+pppingme> blocky sure 04:38 < blocky> i have a home network with a private subnet and a gateway which is doing nat so all traffic general flows to that gateway, but i want to have a vpn gateway on the same subnet but not on the same gateway. is there a "correct" way to get data destined for the vpn subnet (which is different from the regular lan subnet) to flow to the vpn gateway and not the regular gateway? 04:47 <+pppingme> you add a single route to the main router with the subnet of the vpn, and its next hop would be the ip of the vpn server on the lan 04:50 < blocky> so someone else suggested i do that, and it seems like it should work, but whats happening is when a host inside the lan sends a packet (addressed to the vpn gateway but forwarded to the normal gateway, because this host doesn't have that custom route) the normal gateway doesn't seem to forward the packet back to the vpn gateway, and instead just sends an icmp redirect back to the lan host 04:59 <+pppingme> it does both.. it forwards the packet *AND* sends the icmp redirect 04:59 <+pppingme> it does its job, but at the same time is telling client there's an easier way 05:10 < blocky> i think something is not working, because on the vpn gateway using tcpdump i do not see the packet arrive 05:31 < ahyu84> hi guy 05:31 < ahyu84> anyone had idea 05:31 < ahyu84> why windows 10 hardly join domain? 05:31 < ahyu84> I already put DNS to point to the only 1 domain IP address 05:31 < ahyu84> still its state error 05:32 < ahyu84> my windows 7 PC working well with all auto ip and auto dns 05:32 < ahyu84> so weird 05:33 < ahyu84> even I tried reformat to windows 10 its still same issue 05:33 < ahyu84> so weird 05:41 < myxenovia> is voip is just a voice from mic and then turned into bytes to be sent to other end? 05:44 < ahyu84> @myxenovia 05:44 < ahyu84> yes 05:45 < ahyu84> tat why its called Voice-Over-Internet-Protocol 05:45 < phocking> lol 05:45 < ahyu84> in short Voice Over IP 05:47 < Apachez> in short VoIP 05:47 < Apachez> in short wtf is wrong with this shit? 05:51 < myxenovia> ahyu84 well is there other way to send voice instead over ip? 05:51 < myxenovia> in mobile phone 05:53 < myxenovia> well the reason i asked about voip is becuase i dont understand this "Microphone audio source tuned for voice communications such as VoIP" 05:53 < myxenovia> i mean what kind of tuning is it 05:54 < skyroveRR> Analog to digital. 05:54 < ouemt> myxenovia: it probably means the mic is tuned to emphasize frequencies that make the voice more understandable after compression 05:55 < myxenovia> well, if the sender and receiver are both mobile phone, tuning isnt needed because they can both read the same sound 05:55 < ouemt> information is lost during compression. Choosing the right filter or mic response before compression can make a big difference 05:55 < skyroveRR> Compression never occurs over GSM. 05:56 < skyroveRR> The towers would be doing too much work, and too many resources would be needed. 05:56 < ouemt> skyroveRR: https://en.wikipedia.org/wiki/Adaptive_Multi-Rate_audio_codec 05:57 < ouemt> the towers don't have anything to do with the compression, the phone does it before sending it to the tower 05:57 < myxenovia> gotta read more i guess 05:57 < myxenovia> ll 05:57 < myxenovia> lol 05:57 < myxenovia> yea 05:57 < skyroveRR> ouemt: ... I see. 05:58 < skyroveRR> I stand corrected! 05:59 < ouemt> myxenovia: an important part of that article I just linked: "Sampling frequency 8 kHz/13-bit (160 samples for 20 ms frames), filtered to 200–3400 Hz" 05:59 < ouemt> that means that any audio outside 200-3400 Hz is filtered out before compression, so you want a microphone that concentrates its response in that range. The shape of the response will be tuned to maximize comprehensibility after AMR (or similar) compression 06:01 < skyroveRR> So is the phone doing all this before sending it over the network? 06:01 < skyroveRR> Or is the network involved, too? 06:02 < ouemt> skyroveRR: all on the phone 06:02 < ouemt> It's super basic computation 06:03 < jaelae> soo my personal home network but the past two nights by the end of the night my internet speed drops severely to like 1 Mbps down. I check everything but ultimately the fix is to reboot my cable modem and then viola. back to 120+Mbps 06:03 < ouemt> I'd be shocked if the phones didn't have dedicated chips for it 06:03 < skyroveRR> ouemt: so what final output is the network getting?

Also assuming it picks the right 1.1.1.1 from /etc/resolv and puts that in the rules 09:12 < potatoe> yeah it does i checked 09:12 < potatoe> wait do i need any routing things for sysctl? 09:12 < potatoe> I have gateway_enable=YES 09:13 < momomo> light: where are you residing? and don't worry about the pay. to get you onboard I will give you whatever salary is needed to get you onboard ... that is the least of our problems and usually not the first thing that is discussed 09:13 < detha> some googling got 'firewall_nat_enable=YES' in rc.conf 09:16 < potatoe> detha i think that is for inbuilt nat in ipfw 09:17 < potatoe> but I don't have the kernel option enabled for that 09:18 < detha> ah, ok. 09:19 < potatoe> also detha routing was enabled, just to confirm, # sysctl net.inet.ip.forwarding=1 09:19 < potatoe> net.inet.ip.forwarding: 1 -> 1 09:22 < detha> then I don't know. Only thing I can imagine is that the keep-state doesn't catch it; you could try an 'allow from any to any diverted' 09:25 < momomo> DoctorDick: Salary is between 3-4000 eur per month .. but can be more depending on options you want .. we are very flexible depending on if you want to be employed or as a freelance (lower tax hit) 09:25 < momomo> netto 09:25 < potatoe> oh 09:25 < potatoe> thats low 09:25 < momomo> netto? 09:25 < momomo> meaning a salary of 5-6000 pre tax 09:26 < momomo> if not more 09:26 < potatoe> ah thats more like it 09:26 < momomo> hehe 09:27 < potatoe> detha i added allow any to any diverted as rule 1, still not getting caught 09:27 < potatoe> as in detha, still the same as before 09:27 < momomo> can be more netto, if rather than salary we invoice you 09:29 < shtrb|work> If he takes the self employed/freelancer , before deciding please for the sake of all what is holly consulte a tax person 09:30 < shtrb|work> When you choose to take jobs not as an employee you need to handle tax by yourself, and to see if that works for you correctly 09:31 < detha> potatoe: hmm. trying to see where it blocks it - maybe put a 'deny log from 1.1.1.1' at various places, to see where it stops 09:31 < potatoe> detha gotcha, i was also thinking of it and added it after natd divert, let me get the log 09:36 < potatoe> detha even though ive deny from 1.1.1.1 i only ever get this logged 09:36 < potatoe> May 31 23:35:25 alexbsdtest2 kernel: ipfw: 802 Accept UDP 10.0.2.15:48315 1.1.1.1:53 out via em0 09:36 < potatoe> May 31 23:35:30 alexbsdtest2 kernel: ipfw: 802 Accept UDP 10.0.2.15:27467 1.1.1.1:53 out via em0 09:36 < potatoe> that means that the outgoing is getting natd correctly 09:36 < potatoe> but nothing for incoming 09:39 < potatoe> well tcpdump obviously sees the incoming packets but why isnt it logged even though deny log from 1.1.1.1 is set as rule 2 09:39 < detha> odd. and if you temporarily remove rule 50, does it start hitting the deny? 09:39 < potatoe> :/ 09:40 < potatoe> detha yeah if you remove 50 then the deny is caught 09:41 < detha> even though it is later in the list... so 50 rewrites the 1.1.1.1 ? 09:41 < potatoe> seems like it 09:41 < potatoe> that is so weird 09:41 < detha> ok, maybe without rule 50 and a 'allow from any to any diverted' ? 09:41 < potatoe> going to deny log from any 09:42 < potatoe> to see what pops 09:44 < detha> ah wait, 50 will probably rewrite the incoming packet to pretend to come from $EXT 09:44 < potatoe> detha allow from any to any diverted has a syntax error 09:46 < potatoe> detha okay so i added 50 allow ip from any to any diverted and now its getting denied at 799 09:46 < potatoe> meaning it skipped my skipto 09:48 < detha> ok, so that catches it. ehm, skipto 801 ip from any to any diverted ? 09:51 < potatoe> detha it doesnt get caught as diverted 09:51 < potatoe> ipfw: 799 Deny UDP 1.1.1.1:53 10.0.2.15:19336 in via em0 09:51 < potatoe> 00101 skipto 802 ip from any to any diverted 09:52 < potatoe> this is so werid 09:52 < potatoe> what is natd even doing here 09:53 < potatoe> detha sorry i have to go for another meeting so I will be afk for a bit 09:53 < detha> np, chat later 09:54 < potatoe> but btw detha when I try to drill from my normal host it works 09:54 < potatoe> ipfw: 802 Accept UDP 1.1.1.1:53 10.0.2.15:13217 in via em0 09:54 < potatoe> but thats my normal host and not the jail 09:54 < potatoe> but when its from the jail its the exact same deny message 09:55 < potatoe> ipfw: 799 Deny UDP 1.1.1.1:53 10.0.2.15:58660 in via em0 10:03 < dminuoso> Im talking to a friend whose ISP is giving him only a /58 prefix - supposedly their reasoning is "you dont need larger prefixes" 10:03 < dminuoso> What is your opinion? 10:04 < detha> potatoe: it rejects the response, maybe you need to add the keep-state to diverted, in 801 ? 10:04 < dminuoso> Why not simply dish out a /48 for every customer. Residential, business.. 10:04 < dminuoso> who cares. IPv6 prefixes are for free 10:04 < dminuoso> future proof this.. 10:05 < dminuoso> This line of "this will be enough" is exactly what lead to IPv4 exhaustion. The solution is to dramatically oversize everything so it will definitely last... 10:06 < dminuoso> 16 VLANs can quickly be exhausted when you ahve one for your wifi, one for smart home devices, another for your computers.. 10:06 < dminuoso> All this proves to me, is that their admin is a complete moron and doesn't get IPv6. 10:08 < dminuoso> oops. s/vlan/subnet/ 10:08 < shtrb|work> dminuoso, do not connect your home appliences to your router if you care about privacy or dosing yourself 10:09 < dminuoso> shtrb|work: my point is: if you are an ISP and assign /58 prefixes you are seriously limiting choices in what a customer can do network wise - in the digital age where you might have more and more devices with every year, /58 is anything but not future proofing. 10:09 < shtrb|work> "smart home" applinces that have internet access are a pain in the gluteus maximus (remember how the smart HVAC could be disabled form outside) 10:09 < dminuoso> ISPs get IPv6 prefixes for free. 10:09 < dminuoso> So there's no reason to dish out /48 to everyone 10:10 < dminuoso> *not to 10:10 < shtrb|work> they could ask more money for that 10:10 < dminuoso> shtrb|work: so if you start flinging around prefixes with different lengths that increases network complexityu 10:11 < dminuoso> homogenous solutions are just so much easier to set up and reason about 10:16 < ahyu84> hi 10:17 < Gollee> ahyu84: hi 10:17 < ahyu84> LOL 10:17 < ahyu84> cool~ 10:17 < godSend23> howdy 10:17 < ahyu84> office electric down 10:17 < ahyu84> so no working 10:17 < ahyu84> haha 10:19 < godSend23> do u guys have xperiences w/ AWS vs. GCP?

10:35 < shtrb|work> some isps let you put stuff under your account site.com/~username 10:38 < godSend23> brb 10:48 < azizLIGHT> when i launch utorrent, everyone on the LAN cannot browse internet anymore... chrome says no connection and some things fail to load partway or load forever. i put utorrent on throttle but its still happening. problem stops when utorrent quitted 10:49 < TandyUK> your router sucks 10:49 < TandyUK> Ive had this a lot in the past with smaller sonicwalls - they simply cant handle the number of active connections bittorrent uses 10:49 < TandyUK> forget the speeds, but limit the total number of connections utorrent is allowed to make 10:49 < potatoe> detha the keep-state doesn't work either 10:50 < azizLIGHT> oh. is there a way to test what the max might be 10:50 < TandyUK> the fact it struggles at all, I wouldnt waste my time trying to find out, id simply replace the router off the bat 10:50 < TandyUK> im guessing this is some ISP-supplied piece of crap 10:51 < azizLIGHT> i cannot do that unforunately... we only have this internet connection availble here 10:51 < TandyUK> ok, so why cant you replace the router 10:51 < TandyUK> nothgn about the provider, just removve their cheap shit hardware and put in your own router 10:51 < TandyUK> if its cable or something, put the isp supplied PoS into 'Bridge mode' 10:52 < djph> mornin' TandyUK 10:52 < TandyUK> and plug this into the WAN port of your router 10:52 < azizLIGHT> its adsl and the isp is not someone who will cooperate 10:52 < TandyUK> if its adsl, just replace it with any other adsl router 10:52 < djph> (IOW, they won't do it for him) 10:52 < TandyUK> enter your login details, and off you go 10:52 < azizLIGHT> if theres settings to be set, any login to be put in. i cannot obtain it 10:52 < TandyUK> fuck that isp then lol 10:53 < azizLIGHT> not much choice for me unforunately 10:53 < TandyUK> well no torrenting for you then, quite simply 10:53 < dminuoso> azizLIGHT: What country do you live in? 10:53 < azizLIGHT> so how can i test the max # of connections and do the best i can do here 10:53 < azizLIGHT> saudi arabia 10:53 < dminuoso> Yeah well. Deal with it. 10:53 < TandyUK> if you cant/wont replace the router, youre not going to have any real sucess 10:53 < azizLIGHT> like i said... how do i test the max... and make do 10:53 < dminuoso> In Germany you can simply compell the ISP to tell you all details necessary to switch out the router. 10:54 < TandyUK> you make lots of connections, and whe nthe router fals over, you hit the limit lol 10:54 < detha> potatoe: very odd. you have lo1: going towards the jail? 10:54 < azizLIGHT> right thats great for germany 10:54 < shtrb|work> azizLIGHT, you can "guess" the setting if that is ADSL 10:54 < TandyUK> he cant really guess the radius user/pass 10:54 < dminuoso> TandyUK: *PPP 10:54 < TandyUK> the rest, sure 10:54 < dminuoso> CPEs dont speak radius 10:54 < TandyUK> huh 10:55 < shtrb|work> no no, what I meant was the connection settings (the ppp / radius / what ever he already get - printed on the buttom of the device or in the paper you get with the ISP) 10:55 < TandyUK> ADSL logins use radius, whether you thing the CPE 'speaks radius' or not 10:55 < TandyUK> yeah thats what he says isp wont give him 10:55 < TandyUK> sounds like a bullshit isp / monopoly 10:55 < dminuoso> TandyUK: Your modem/router at home does not speak RADIUS generally. 10:55 < shtrb|work> It's printed on the devices (buttom side) 10:56 < dminuoso> TandyUK: They set up PPP (the other endpoint may use RADIUS, DIAMETER or whatever to authenticate you) 10:56 < TandyUK> dminuoso: the username and password for the connection, is checked, on isps end, in their radius database 10:56 < dminuoso> TandyUK: RADIUS is not a database either. 10:56 < dminuoso> TandyUK: You are conflating so many things. Please stop. 10:56 < TandyUK> so he still needs the username and password, which he said ISP wont give him 10:57 < TandyUK> dminuoso: are you trying to help this guy, or just confuse the fuck out of him? 10:57 < azizLIGHT> im using ZTE ZXV10 adsl modem on 10240 kbps down / 860 kbps up (up is definitely a lie) 10:57 < dminuoso> TandyUK: You also dont know whether he needs a username or password at all. 10:57 < TandyUK> Im attempting to use terms a normal noob might actually understand, whether its 100% accurate or not 10:57 < shtrb|work> dminuoso, radius is a feces load of things, it does the accounting , authntication and authorization 10:57 < dminuoso> Some ISPs dont do any authentication and merely identify you through some port id 10:57 < TandyUK> some dont use radius, sure. 99% DO 10:58 < dminuoso> TandyUK: RADIUS is not a database. It's just a protocol. And routers you typically have at home dont understand RADIUs. 10:58 < dminuoso> They dont speak RADIUS. 10:58 < TandyUK> oh fuck me, i never said they did, YOU did 10:58 < TandyUK> I just said he needed to know the user/pass 10:58 < shtrb|work> azizLIGHT, is that a custom firmware , do you remember your talk with the rep when they have installed it at your side ? 10:59 < azizLIGHT> shtrb|work: its a ZTE brand adsl model (chinese). no custom firmware. they set it up and hand it to me and hope for the best 10:59 < dminuoso> azizLIGHT: Can you look at the settings? 10:59 < shtrb|work> dminuoso, I didn't see a single ISP that did not use radius (and the ones that uses Diameter had a translator unit installed) 10:59 < dminuoso> azizLIGHT: Check if there's any credentials. 10:59 < azizLIGHT> yes i guessed the logins: admin:admin 10:59 < azizLIGHT> i see them but they are all ***s 10:59 < dminuoso> shtrb|work: Some dont authenticate at all. 11:00 <+catphish> azizLIGHT: if they only support their own router, i don't see what option you have apart from just complaining to them that it's broken :( 11:00 < TandyUK> azizLIGHT: if the router is _that_ shit, you might find the password in plain text embedded in the html code of the relevant page 11:00 < azizLIGHT> hmmm that actually is a good idea. but it means downtime for me 11:00 < shtrb|work> dminuoso, I was talking about RADIUS (the access-request is auth ) 11:00 < dminuoso> shtrb|work: I have a working understanding of RADIUS. Thank you. 11:00 < azizLIGHT> TandyUK: ill look 11:00 <+xand> yeah view the source of the HTML, it might show the password etc 11:01 < shtrb|work> dminuoso, ok then 11:01 < shtrb|work> azizLIGHT, is that router + modem or just a router ? 11:01 < TandyUK> you'll be looking for an field, with hopefully a value="something" param 11:01 < azizLIGHT> its a modem + router, but i use my own router because that one is shit 11:01 < azizLIGHT> i have jsut 1 client for it, my 2nd rotuer 11:03 < shtrb|work> Sometimes when you choose the backup setting in the routers, the file will have the credntials there (the password might be hashed) 11:04 < shtrb|work> azizLIGHT, What is the exact model ? 11:04 < dminuoso> shtrb|work: it cant be hashed because then its irrecoverable 11:04 < azizLIGHT> ZTE (brand) ZXV10 (model) 11:04 < shtrb|work> tell that to juniper (the backup file uses a hash) 11:05 < dminuoso> shtrb|work: how would it recover the original password then? 11:05 <+xand> it could only use hashes for passwords that are used to access the router 11:05 <+xand> not for passwords the router uses to access other things 11:06 < dminuoso> shtrb|work: The fortinet VPN client for example does some pretty obfuscation, but it's 100% recoverable if you understand the algorithm. 11:06 < shtrb|work> he won't but, with ADSL routers many times password = account number | phone numberetc 11:06 < shtrb|work> dminuoso, ok 11:06 < dminuoso> but thats not hashing 11:07 < shtrb|work> azizLIGHT, google says access comands are "admin/admin, zxdsl/zxdsl, Administrator/admin" 11:08 < azizLIGHT> yep im in the administration area already 11:08 < azizLIGHT> with admin admin 11:09 < azizLIGHT> the pre-filled ****'s for the password dont seem to have a value="" in the html 11:09 < azizLIGHT> for the pppoe 11:09 < azizLIGHT> i can see the username though 11:10 < shtrb|work> do you have several "circuit configurations"? 11:10 < azizLIGHT> if you mean pv0 through pvc7, yes 11:10 < azizLIGHT> *pvc0 11:10 < shtrb|work> go over ALL of them , sometimes you have several setup there 11:11 < azizLIGHT> they put the internet on pvc1, everthing else is bridge mode 11:12 < shtrb|work> I wonder if you could select a bridge mode to be active, setup pppoe on your router with that username to see if that will work 11:12 < shtrb|work> and try password='username' password='' password='accountid' password='phonenumber' 11:12 < shtrb|work> etc 11:13 < azizLIGHT> well i wouldnt want to mess up how it is now. because it would mean i would be offline for months 11:14 < azizLIGHT> for them to replace things... and wait time 11:14 < azizLIGHT> and its ramadan 11:14 < azizLIGHT> they dont do shit in ramadan 11:14 < shtrb|work> they don't work on ramadan ? 11:14 < azizLIGHT> hardly... 11:14 < shtrb|work> so call after night fall 11:15 < azizLIGHT> meanwhile i put utorrent on max # of connections to 15, and it seems to be ok for other comptuers on the LAN for browsing now 11:17 < azizLIGHT> its a low # of connections sure, but at least we can browse while do some downloading 11:19 < shtrb|work> I don't think if you choose a different active circuit you will not be able to go back or if it will overwrite the other ones 11:19 < shtrb|work> So if you have pvc0 - internet , and you select pvc1 as active - if there is a problem you should be able to select pvc0 again 11:19 < shtrb|work> but there is no gurntee for it 11:20 < djph> probably best to do that on the router he owns 11:20 < djph> err *on a modem* he owns 11:21 < azizLIGHT> yeah, can i just get any adsl modem? 11:21 < shtrb|work> just make sure it support your profile but yes (Vdsl XXX or ADSL xxx) 11:22 < shtrb|work> 99% the ones sold in your contry should support ALL isps 11:22 < azizLIGHT> ive found that when i browse on my vpn to USA, i dont get those errors from chrome about no internet, or partial loading, or loading forever 11:23 < azizLIGHT> works just fine on VPN 11:23 < azizLIGHT> so ive been doing that but some things i cant be doing on the VPN, like torrents 11:25 < shtrb|work> Google says Zain has forgot my password 11:26 < shtrb|work> maybe your ISP also have such an option 11:26 < azizLIGHT> if its possible to reset/obtain without interacting with a human, then id consider it 13:50 < afidegnum> hello, i have a debian where proxmox kvm is installed, i have a WindowsVm with it's own public IP, i have also manually configured the IP address, DNS etc.. but i can't access my IP publicly, what can be the cause? what do i need to do? 13:51 < djph> your entire network has public IP addresses then? 13:53 < afidegnum> when i ping that ip address, i get an empty response 13:57 < djph> and you 'own' the addres; you have properly set up routing for it; you're not in a situation where the IP has to be on your edge 14:06 < afidegnum> djph: i have 2 ips, one for the dedi server and one for the VM 14:09 < djph> and you've properly set up routing for them / they are actually routed to you? 14:10 < Rayben> AustNet 14:10 < varesa> Is the VM bridged to the dedi interface? 14:11 < varesa> Also some providers require you to give the VM MAC address to some interface of theirs 14:20 < afidegnum> yes the VM is bridged using Vmbr0 14:20 < afidegnum> i have configured the IP mac address as well 14:29 < varesa> can you pastebin the output of "ip a" on the host? 14:34 < v0Lk> varesa: yes, but you'll have to use the pastebin API 14:34 < varesa> v0Lk: that was a request to afidegnum :) 14:35 < v0Lk> kk 14:44 < Rayben> Interpretatio graeca (Latin, "Greek translation" or "interpretation by means of Greek [models]") is a discourse[1] in which ancient Greek religious concepts and practices, deities, and myths are used to interpret or attempt to understand the mythology and religion of other cultures. 14:56 <+catphish> azonenberg: is your switch design all private at the moment?

Tellurocratic states have a certain territory and the state-forming ethnic majority living on it, around which further expansion takes place. The opposite of tellurocracy is thalassocracy (maritime empi 15:14 < Rayben> res), although in the pure type of a particular state is rarely observed. Usually there is a combination of tellurocratic characteristics with thalassocratic. 15:14 < varesa> atleast with KVM/libvirt the VMs create vnetN interfaces on the host that are part of the bridge, don't see that in your paste 15:15 < tds> yeah, pve will create tap interfaces for each vm, should be tapi 15:15 < afidegnum> varesa: i don't get you 15:15 < tds> are the vms running at the moment? what's the output of qm list? 15:16 < afidegnum> ok, from the interface, i can launch the VM, have access to it 15:16 < Cooler> Hi 15:16 < afidegnum> but the IP doesn't populate outside, 15:16 < Cooler> Is there a way to find out what's happening on your lab using nmap? 15:16 < afidegnum> strange enough installed teamviewer on the VM and had access to the server from outside, 15:16 < `whoami`> thanks for checking.

15:35 <+catphish> i assumed you were using linux since you had netmap 15:36 <+catphish> but on windows, yes 15:36 <+catphish> *nmap 15:36 < Cooler> Nmap is cross platform 15:36 < djph> yeah, but windows people knowing about it ... 15:36 < Cooler> An error occurred 15:37 < Cooler> Unable to contact DHCP server 15:37 < Cooler> Request timed out 15:37 <+catphish> reboot maybe 15:37 <+catphish> but sounds like your network is just down completely 15:37 <+catphish> hence why you can't ping the gateway 15:37 < Cooler> I need to find the actual DHCP on the network 15:37 <+catphish> windows does that for you, it's clearly not there 15:37 < Cooler> Not the bogus ones created by personal routers 15:38 <+catphish> it seems far more likely there's simply no DHCP server at all 15:38 < bezaban> or out of leases 15:38 < Cooler> What makes you think that 15:38 <+catphish> unless you're on wifi, then maybe you're accidentally connected to the wrong access point, or a rogue one, or a broken one 15:38 < Cooler> No this is Ethernet 15:38 <+catphish> ok, then the network is just broken 15:38 < bezaban> nmap has a dhcp discovery script that may be helpful 15:39 < Cooler> Ok 15:39 <+catphish> first gateway didn't respond, then dhcp didn't respond 15:39 < Cooler> What's the command 15:39 <+catphish> seems like the network is just "down" to me 15:39 < bezaban> but I would check the dhcp server first 15:39 <+xand> you could use wireshark to monitor DHCP requests/responses 15:39 <+catphish> but you did discover some other hosts, right, so not totally sure 15:40 <+catphish> yes, i'd definitely be watching with wireshark as xand says 15:40 < Cooler> Yeah there's several hosts up 15:41 <+catphish> interesting 15:41 <+catphish> maybe their router is broken 15:41 < tds> if it is a rogue dhcp server, could be that other devices have picked up addresses in the wrong subnet as well 15:41 <+catphish> or maybe there was a rogue dhcp that's now gone 15:41 <+catphish> in my experience most OSs suck at renewing DHCP, hence the reboot suggestion too 15:41 <+catphish> it may be triying to connect to the (now absent) rogue dhcp 15:42 <+catphish> hard to guess really 15:42 < tds> either way, this sounds a lot like a question for whoever runs the network, and try and get them to filter dhcp + RAs while you're there :) 15:43 <+catphish> is it common for firewalls to close active TCP connections after exactly 60 minutes? 15:43 < Cooler> Can i just run the dhcp script? 15:43 < Cooler> Whatsthecommandforthat? 15:43 <+catphish> have you tried turning it off and on again? 15:43 < bezaban> --script=broadcast-dhcp-discover 15:43 < bezaban> but that will look for DHCPOFFER, so if it's a question of DHCP gone or out of leases then that won't help 15:44 < Cooler> So reboot then?

15:59 < Cooler> I don't know 16:00 < Cooler> It says 172.16.56.253 16:00 < Cooler> 235 16:00 < Cooler> I think that's the same as before reboot 16:01 < Cooler> The default gateway is 172.16.57 16:01 < Cooler> .253 16:01 < Cooler> Which looks suspicious 16:01 <+xand> does it? 16:02 < Cooler> My IP is 235 and the gateway is 253 16:02 < tds> that's perfectly valid 16:03 <+xand> so 16:03 < Cooler> Can't do anything, same as before 16:04 < tds> if you suspect it's a rogue dhcp server, worth checking with nmap or just doing a packet capture and making windows send a dhcpdiscover 16:05 < tds> seeing as you got an address, you should get at least one response 16:06 < Cooler> Can I scan all IPs in my network for a particular port 16:06 < Cooler> The University uses port 8090 16:06 <+catphish> that gateway sounds correct 16:07 <+catphish> Cooler: what happens when you ping 8.8.8.8 16:07 < Cooler> Can't ping it 16:07 <+catphish> yes you can 16:07 < Cooler> Times out 16:07 < Cooler> Request timed out 16:07 <+catphish> ok, that doesn't help much then 16:08 < Cooler> What's the nmap command to scan all hosts on 8090 16:08 <+catphish> Cooler: try reading the manual, it's probably trivial to find 16:09 <+catphish> search for "port" 16:09 <+catphish> Cooler: also, can you paste your arp table? 16:10 <+catphish> this will tell you if the gateway is totally absent, or just not forwarding your packets 16:11 < Cooler> How? ARP -a 16:11 < Cooler> ? 16:11 <+catphish> i don't know windows 16:12 < Cooler> So I scanned 8090 16:12 < Cooler> It's saying TCP filtered ops messaging 16:12 < Cooler> On all hosts 16:13 < Cooler> Can you tell me what I need to look for in the ARP table 16:14 < Cooler> It's kinda hard for me to post without a net connection 16:14 < tds> an entry for the gateway's ip 16:14 < Cooler> The gateway entry says dynamic 16:14 <+catphish> does it have a MAC address 16:14 < Cooler> Along with the Mac address 16:15 < Cooler> Yes 16:15 <+catphish> ok, so i'd say the DHCP and gateway are working fine, but there's just no internet connection 16:15 < tds> so the router is at least replying to arp, that will also tell you the router vendor 16:16 <+catphish> network broken upstream, or... the router is deliberately blocking your traffic because you triggered some kind of security mechanism 16:16 < tds> might be worth looking up, if it's tp link or something then that sounds like rogue dhcp (assuming the uni isn't running tp link routers) 16:16 < Cooler> I should mention that I tried opening Wireshark and it's stopped responding 16:16 < Cooler> Every time 16:16 <+catphish> my best guess says because of the obscurity of the subnet, it's probably legitimate 16:17 <+catphish> either the upstream internet is broken, or the router blacklisted the client 16:17 < tds> ah, good point, people running rogue dhcp servers probably all have them on 192.168.0.0/24 or something 16:17 < Cooler> It's stuck at "initializing external capture plugins" 16:17 <+catphish> tds: not necessarily, but most likely if its an accident 16:18 < tds> catphish: yeah, I was just thinking of the scenario of pulling a tp link thing out the box and plugging it into the uni network 16:18 < Cooler> The University uses tenda 16:18 < Cooler> I have seen students with tplink routers 16:18 < Cooler> The use it to get WiFi 16:18 < Cooler> From the Ethernet 16:19 < Cooler> They* 16:19 <+catphish> that's a pretty normal thing to do 16:19 <+catphish> i do that at home :) 16:19 < tds> that sounds quite common, shouldn't cause issues with the wired network as long as they configure them correctly 16:19 <+catphish> Cooler: you can look up the MAC of the router to check who the manufacturer is 16:19 < Cooler> I don't think anyone configs anything 16:19 < Cooler> Just plug and play 16:19 <+catphish> thats usually fine too 16:20 < tds> as long as you plug the uni network into the right port, should be fine 16:20 <+catphish> defaults are pretty sane, as long as you plug in the right port 16:20 <+catphish> if you use the LAN port, you break everything :) 16:20 < Cooler> I wonder if my network card is borked 16:20 <+catphish> it's not 16:20 * tds hopes most unis have switches configured to filter dhcp at this point 16:20 < Cooler> Wireshark stops responding every time I open it 16:21 <+catphish> tds: you'd hope so 16:21 < tds> here they filter dhcp, but apparently forgot about RAs ;) 16:21 < Cooler> I can't ping the default gateway 16:21 < Cooler> Request timed out 16:22 < Cooler> Something is up 16:22 < Cooler> Maybe an ARP poisoning? 16:22 <+catphish> Cooler: see my comment about checking the mac manufacturer 16:23 < Cooler> The Mac of which router 16:23 < Cooler> Look it up where 16:23 <+catphish> routers don't always respond to ping, they really should, but some don't, my best guess here is that you pissed off a security mechanism and got blocked 16:23 < Cooler> It says tenda and tp link when I nmap scan 16:23 <+catphish> Cooler: https://macvendors.com/ or https://www.macvendorlookup.com/ 16:24 <+catphish> it can't be both surely 16:24 <+catphish> it must say one or the other 16:25 < Cooler> It's Dell inc 16:25 <+catphish> well that's unexpected 16:25 < tds> do dell even make routers? 16:26 < tds> could be a l3 switch I guess 16:26 <+catphish> i don't think do 16:26 <+catphish> *so 16:26 < Cooler> 3417eb51fd75 16:26 <+catphish> 1) this would explain why you lost internet access *and* stopped being able to ping the router, even though it's there and 2) the fact you knew you could ping the router earlier, and you have nmap installed implies that you were testing things and could have tripped an IDS 16:26 < Cooler> That's the Mac address of the default gateway 16:27 <+catphish> that is indeed dell 16:27 < Cooler> I wasn't testing anything, the net just stopped working a few hours ago 16:27 <+catphish> but you said you could ping the router before 16:27 < Cooler> I have nmap installed because its required for lab work 16:27 <+catphish> that alone wouldn't be a problem though 16:28 < Cooler> I could ping the router yes 16:28 <+catphish> anyway, the facts here are simple: you're connected to the network, you can see the router, but it's not routing your traffic to the internet 16:28 <+catphish> you can only complain 16:28 < Cooler> I don't think I can see the router 16:28 <+catphish> you can 16:28 < tds> well you can see something claiming to be the router 16:28 <+catphish> its in your arp table 16:28 < Cooler> You said l3 switch? 16:29 <+catphish> well yeah, something claiming to be the router, it's probably the router 16:29 < tds> whatever it is, sounds like you need to talk to whoever runs that network 16:29 < Cooler> Well like i said the University uses tenda 16:29 < Cooler> Not dell 16:30 <+catphish> also, there's really nothing you can do about this :( 16:31 < Cooler> Well yes there is something 16:31 <+catphish> as i said to begin with, this is beyond your control unfortunately 16:31 < Cooler> I can find the tenda router 16:31 < tds> you could try sending an arp request for the gateway and seeing if you get multiple responses, then add a static entry for one you think is right, that doesn't really fix the actual problem though 16:31 < Cooler> And manually set the gateway 16:31 <+catphish> well did you find that in nmap? 16:32 < Cooler> 172.16.57.20 is tenda according to nmap 16:32 <+catphish> i'd guess that's far more likely an AP 16:33 < Cooler> 56.20 16:33 < tds> having a gateway in the middle of a subnet would be unusual (assuming that's a /24) 16:33 <+catphish> it's /23 but yes 16:34 < Cooler> Can I set just the gateway? 16:34 <+catphish> not usually 16:34 <+catphish> but maybe, i don't know windows well 16:34 < Cooler> It's asking me to set IP and subnet mask as well 16:34 <+catphish> well you can set that to your current IP (temporarily) 16:36 < s7rawman> catphish: You were correct. (vpn issue from yesterday) The hosts aren't aren't routing back through the tunnel. 16:36 <+catphish> s7rawman: did you get it working? 16:36 < s7rawman> Negative. 16:37 <+catphish> s7rawman: you need to add a route to the VPN clients on the default gateway of that network 16:37 < Cooler> Well that didn't work 16:37 <+catphish> (probably) 16:37 <+catphish> Cooler: i still bet that's an access point 16:37 < Cooler> WiFi access point? 16:37 < s7rawman> Alright. 16:37 <+catphish> people don't put routers on .20 16:37 <+catphish> Cooler: yes 16:37 < s7rawman> thank you 16:37 < Cooler> Is .20 special? 16:37 <+catphish> no 16:37 <+catphish> and that's the point 16:38 <+catphish> routers normally go right at the start or the end, .20 would be a bit random 16:38 <+catphish> .1 .2 .3 .252 .253 .254 are common places to see routers 16:38 < detha> catphish: I distinctly remember some vendor having 192.168.1.20 as default after factory reset 16:39 < Cooler> Why 16:39 <+catphish> detha: eww, but ok :) 16:39 < Cooler> Because they are near the start and the end? 16:39 <+catphish> Cooler: it just makes sense when you're designing a network, leaves a continuous range for clients with dynamic IPs 16:40 < Cooler> Netgear is an access point that shows up 16:40 <+catphish> if you put the router on .20 then you have to exclude .20 from DHCP, plus it's just confusing and unnecessary 16:40 <+catphish> ok 16:40 < detha> ah. https://community.ubnt.com/t5/The-Lounge/Factory-Default-IP-Address/td-p/198719 16:40 <+catphish> but access points are no good to you 16:41 <+catphish> you need to find the router 16:41 <+catphish> and i bet it's where DHCP says it is 16:41 < tds> detha: are those APs or something? 16:41 <+catphish> yes they are 16:41 < Cooler> What is wsdapi? 16:41 < tds> I guess if you're selling routers and APs, giving the routers say .1 and the APs .20 by default would make sense 16:41 < detha> tds: little APs 16:42 <+catphish> Web Services on Devices allows a computer to discover and access a remote device and its associated services across a network. It supports device discovery, description, control, and eventing. The WSD API functionality is implemented in the WSDApi.dll module in Windows, and is used by several services and applications. 16:43 < Cooler> For what 16:43 < Cooler> Is it part of windows 10 home edition 16:43 < Cooler> Sounds like something for Windows server 16:44 <+catphish> you'll have to research it, not much love for windows here 16:44 < Rayben> Maritime history is the study of human interaction with and activity at sea. It covers a broad thematic element of history that often uses a global approach, although national and regional histories remain predominant. As an academic subject, it often crosses the boundaries of standard disciplines, focusing on understanding humankind's various relationships to the oceans, seas, and major waterways of the globe. Nautical history records and interprets 16:44 < Rayben> past events involving ships, shipping, navigation, and seafarers. 16:45 < Cooler> Ok things started working suddenly 16:45 < Cooler> I can reach the University login server now 16:45 < Cooler> On 172.16.0.1 16:46 < Cooler> Maybe whoever was messing things up disconnected their router? 16:46 < tds> could be, do you still see the same mac address in the arp table entry? 16:47 < Cooler> Suddenly there's a lot more entries 16:47 < Rayben> Since the turn of the millennium, the construction of stealth ships have occurred. These are ships which employs stealth technology construction techniques in an effort to ensure that it is harder to detect by one or more of radar, visual, sonar, and infrared methods. These techniques borrow from stealth aircraft technology, although some aspects such as wake reduction are unique to stealth ships' design. 16:47 < Cooler> Oh it changed 16:47 < Cooler> The Mac address changed 16:48 < Cooler> 0004966cf77e 16:48 < Cooler> Extreme networks 16:48 < `whoami`> ahah some guy was trying to mitm but didn't enable forwarding ? :p 16:49 <+catphish> Cooler: interesting, i guess someone fixed something, or quite likely someone accidentally configured a server on that IP and it's not been removed 16:49 <+catphish> *now been removed 16:50 <+catphish> now we know the real router is Extreme, the dell was likely just a server with a misconfigured IP 16:50 <+catphish> make a note of the extreme's MAC, if it ever happens again, you can manually add that MAC to your arp table :) 16:52 < Cooler> Ok 16:55 < Cooler> Actually it's tenda 16:55 < Cooler> c83a354cd040 16:55 < Cooler> I had the wrong Mac before 16:56 < Cooler> And it's on 172.16.56.20 16:56 < Cooler> And it's listed as dynamic 16:57 < Cooler> So somehow the access point is now working as a gateway 16:58 < Cooler> Also why is there an entry for the broadcast address in the ARP table 16:58 < tom_ato> i'm sure the answer to this is "it depends" but how many clients should one be able to squeeze out of a single public IP 16:58 < Cooler> It's set to FF FF FF FF FF FF 16:59 < Cooler> Also there are entries for IPs 224.0.0.2 16:59 < Cooler> 224.0.0.22 16:59 < Cooler> 224.0.0.251 17:00 < Cooler> Etc, but why? They aren't even in the same subnet 17:00 < mAniAk-_-> tom_ato: a lot 17:00 < Cooler> Also one for 239.255.255.250 17:00 < tom_ato> mAniAk-_-: so if i'm seeing socket errors with 100 clients 17:00 < mAniAk-_-> tom_ato: something wrong then 17:01 < tom_ato> indeed 17:01 < mAniAk-_-> but also depends on nat type, but its usually the good one 17:01 < tom_ato> just PAT, meraki MX 17:01 < mAniAk-_-> several types of PAT 17:01 < mAniAk-_-> :) 17:01 < tom_ato> rip 17:01 < mAniAk-_-> but i guess meraki should be okay 17:01 < tom_ato> well issue started as people randomly unable to send / recieve in outlook for 10-20 minutes 17:02 < tom_ato> doing a speed test at the same time, site reported back socket error 17:02 < tom_ato> so just gonna do some pcaps and see if anything else jumps out 17:02 < mAniAk-_-> just get wireshark/tcpdump out on client and meraki and see whats going on 17:02 < tom_ato> ayyyy 17:03 < Cooler> catphish why are there entries in the range 224.x.x.x 17:03 < Cooler> In the ARP table 17:03 < mAniAk-_-> but, established connections should be okay if you were hitting some resource limitation on the amount of connections you have 17:03 <+catphish> Cooler: multicast 17:04 < Cooler> What 17:04 <+catphish> you asked what 224.x.x.x addresses were 17:04 <+catphish> they're multicast 17:05 < Cooler> That's weird 17:22 < Cooler> It's weird that there's no entry for 172.16.0.1 but there is one for 224.x.x.x 17:23 < tds> that 172.16.0.1 address will be multiple hops away 17:23 < tds> so it won't appear in your arp table, only the gateway will 17:25 < Cooler> TDS the gateway is listed as .20 17:25 < Cooler> The tenda access point 17:26 < Cooler> It's all very weird 17:26 < tds> if you do traceroute 172.16.0.1, you'll probably see the first hop being the gateway? 17:27 < Cooler> Yeah but isn't it supposed to be 17:27 < Cooler> .1 .2 .3 etc 17:27 < tds> did you get that gateway from dhcp, or set it yourself? 17:29 < Cooler> I did ipconfig 17:29 < Cooler> I didn't set it manually 17:29 < Cooler> I mean I did set it manually but that didn't work so I set it to automatic and rebooted 17:36 < Cooler> And as usual I can't do anything about networking 17:36 < Cooler> It's down to hoping whoever is screwing things up just decided to stop 17:36 < Cooler> Decides* 17:39 < tom_ato> mAniAk-_-: so pcap shows that client sends traffic, server replies. 2 retransmissions with PSH, ACK flags happened from the client PC but thats pretty much it 17:44 < s7rawman> catphish: Thanks for your help. I got it figured. It wasn't a true site to site, it just mimiced it. 17:46 <+catphish> s7rawman: well that's really up to you, i guess you used NAT or bridging instead 17:54 < s7rawman> catphish: Well I didn't build the tunnel, it's a client server vpn, with some aweful routing rules stuck on the hosts. The Data center I'm using has explicitly stated that it's not possible to build a site to site on their end unless we pay some exorbant maintenance fee. So I'm stuck here for now. 17:58 <+catphish> i see, well running NAT on the VPN server will likely make it work, but i guess you figured something out anyway 17:59 < s7rawman> Thanks for your help. I appreciate it. 18:17 < Xiretza> does anyone know how management VLAN works on netgear switches? so far I've had the experience that it always answers untagged (even if the request comes in tagged) on my SOHO switch, are professional ones better? 18:18 < tds> what netgear switch is it? 18:18 < tds> their cheapo smart one (gs108e I think) behaves like that, you can only manage it sending untagged frames, but regardless of the vlan the port is on 18:19 < tom_ato> might be more of a sysadmin thing...but any more bites on this issue? Outlook randomly disconnected from exchange (cloud) for various users at all times, for short periods. 18:19 < Xiretza> ah yeah that's the one I have right now, looking to buy a GS516TP 18:19 < Xiretza> tds: ^ 18:20 < tds> probably worth looking through the manual to see if there's a management vlan setting 18:20 < Xiretza> there is, but what do I know, maybe that's just a receiving filter 18:20 < tds> yup, the manual mentions a setting for it, so you'll probably be fine 18:21 < fattredd> I've got something weird happening. I'm connected to my home openvpn server, where I was sshing into a server. When I connect the server to a third party VPN (PIA), I can no longer ssh in from work. I CAN, however, ssh into another local machine that is able to ssh into the server. 18:21 < Xiretza> tds: thanks for the insight :) 18:21 < tds> Xiretza: it says "When the management VLAN is set to a different value, an IP connection can be made only through a port that is part of the management VLAN", so yuo have reasonable grounds to complain to netgear if it doesn't behave like that 18:21 < tds> s/yuo/you/ 18:23 < Xiretza> tds: yeah but a port only being part of a VLAN could also be "PVID is X and it's assigned to X untagged", in which case it would work even if it's broken /shrug 18:23 < fattredd> Did I word that okay? I realize that's sort of ambiguous 18:25 < Xiretza> fattredd: so your VPN server can no longer connect to the problematic server, but another local machine can? 18:40 < plujon> I'm shopping for a router. Any advice, in the wake of VPNFilter news? 18:45 < fattredd> That's right Xiretza 18:45 < fattredd> no wait 18:45 < fattredd> My work PC cannot connect to the home server 18:46 < fattredd> It is able to connect to other home devices 18:46 < acos> Howdy all 18:46 < fattredd> Other home devices are able to connect to the home server 18:47 < Xiretza> fattredd: sooo you're trying to connect directly from work to home server? so your home VPN is irrelevant? 18:47 < acos> Wow sounds secure. Good luckkk 18:48 < fattredd> No. I'm connected from work to my home network through a vpn 18:48 < Aeso> acos, o/ 18:48 < acos> Not you hahahhaha 18:48 < Aeso> :) 18:48 < acos> Tis i 18:49 < Xiretza> fattredd: ok, and now you're trying to connect to your home server (let's call it orange unless you have a better name) through your home VPN (which runs on, let's say blue, which is in the same network as orange)? 18:50 < acos> Throw some NAT in there shell be right 18:50 < fattredd> Why don't I draw up a chart 18:50 < Xiretza> great idea 18:50 <+catphish> morning 18:50 < Xiretza> heya 18:53 < acos> Morning cat 18:57 < fattredd> Okay. https://imgur.com/a/ugvJOkW 18:58 < fattredd> Here's what I got 18:58 < tds> I like the "magic internet box" :) 18:58 < fattredd> heheh 18:58 < fattredd> SO. Work laptop is connected to home VPN 18:58 < guideX> I'm confused on how to prevent http traffic from going around the firewall on my sonicwall firewall for specific users 18:59 < tds> from a quick glance, it sounds like you're missing a route on the "home server" towards the vpn subnet via the home router 18:59 < tds> so running openvpn on the server will replace your default route, but you'll keep your on-link route to the local network, so you can still reach stuff there, just not anything else via the home router 18:59 < guideX> so far, we setup the local os firewall to block traffic not coming from the proxy, but it's a pain 18:59 < fattredd> work laptop is totally capable of sshing into home pc, and home laptop 19:00 < fattredd> Hold on 19:01 < shanee> Hi. I'm trying to setup a router connecting to another router I don't control. (For a different ssid and guest network.) The main router has dhcp for 192.168.1.* if I set ours to 192.168.2.* is this all I need to do? Are there any other gottchas? 19:01 < fattredd> So because home vpn server gives me a 192.168.2.0/24 IP address, the home server (192.168.1.0/24) is unreachable? 19:02 < fattredd> interesting 19:02 < tds> I suspect it's the inverse of that, you can route to the home server fine, but it can't route back to you 19:02 < fattredd> Weird. Okay I buy that. So I can fix that with a new route? 19:02 < tds> something like "ip route add 192.168.2.0/24 via 192.168.1.1" (assuming the vpn server is 192.168.1.1 on the lan) may solve it? 19:02 < tds> (running that on the vpn server) 19:04 < Xiretza> fattredd: so home PC can reach home server, but work laptop (with home VPN internal IP) can't reach home server? 19:04 < fattredd> That's right 19:05 < Xiretza> ugh weechat was being hangy, lemme catch up 19:05 < fattredd> tds: Okay I'll see what I can get 19:05 < tds> if you're able to reach other devices on the home lan over the vpn, and then jump from there to the home server, but not go directly, that sounds a lot like a missing route to the vpn subnet from the home server to me 19:06 < Xiretza> yeah, that's exactly it. all other home devices have default route through home router, which tunnels 192.168.2.0 through VPN, but home server just encapsulates 192.168.2.0 rightaway 19:07 < fattredd> I'm not sure I get why a route on the router would change things though. Shouldn't the route be on home server? 19:07 < Xiretza> fattredd: yes 19:08 < Xiretza> the router already has that route 19:09 < fattredd> Sweet 19:09 < fattredd> Looks like it's working with the new route 19:09 < fattredd> Thanks guys 19:10 < tds> Depending on what the home server is using for networking, it may be a bit of a pain to add the static route nicely 19:11 < tds> For ifupdown you can probably just use post-up hooks 19:12 < fattredd> I'm not sure I know what you mean 19:13 < tds> For adding it permanently (if you added it with ip, the route will be lost on reboot) 19:13 < fattredd> Looks like Ubuntu uses netplan 19:14 < tds> Ah, is this 18.04 server? 19:14 < fattredd> Yes indeedy 19:14 < fattredd> I have no idea how netplan works though lol 19:15 < tds> Haha, me neither, my only experience is with uninstalling it so far ;) 19:15 < fattredd> hue hue 19:21 < plujon> I have a Motorola SB6141 and a D-Link DAP-1720. Can I setup a wifi network and use the Internet using only these 2 devices? 19:21 < fattredd> Actually not bad. It's just a .yaml file 19:21 < plujon> If I plug the latter into the former, my linux laptop gets an ipv6 address, but not ipv4 address. 19:22 <+catphish> plujon: you really need a router too 19:23 < plujon> catphish: That's what I thought. I'm a little confused about what hardware qualifies as a "router". 19:24 <+catphish> plujon: well any device that calls itself a router would be a good start 19:24 <+catphish> plujon: the normal home setup is a modem, like you linked, plus a "wireless router", which is a router and a wireless access point in one device 19:25 <+catphish> like these: https://www.tp-link.com/uk/products/list-9.html 19:25 < plujon> Since I already have an AP, I wonder if I should buy a router without wireless. 19:26 <+catphish> yes, you can do that if you prefer 19:26 <+catphish> you will find that most home routers come with wifi included though 19:27 <+catphish> so there might be no benefit 19:28 < plujon> Interestingly, I could access the Internet over ipv6 whilest using only these 2 devices and a wifi connection, but only for a short period of time. 19:29 <+catphish> that setup would in theory work, the main problem is that the ISP will only give you one IPv4 address, so it's not very practical 19:29 <+catphish> maybe the AP itself got the IP before you did 19:30 <+catphish> i'd expect ipv6 to work because IPv6 addresses are essentially unlimited 19:31 <+catphish> if you're looking to minimize cost, mikrotik make cheap wired routers 19:31 < tds> it's also likely you have no firewall between you and the internet at that point, which isn't a great solution 19:31 < tds> s/solution/situation 19:31 <+catphish> or you may be able to get a tp-link router with wifi very cheap too 19:31 < tds> apparently I can't english today 19:32 < grawity> fortunately all the good operating systems have host firewalls active by default 19:32 <+catphish> indeed, you really want a router to firewall your device(s) 19:34 < plujon> Thanks for the tips. I guess I'll buy a router. 19:34 < tds> grawity: don't desktop debian/ubuntu still not include a firewall enabled by default? 19:34 < tds> that may not fit your definition of good though ;) 19:34 < grawity> let's say I define "good" as "has a firewall active by default" 19:34 < tds> heh :) 19:34 <+catphish> it doesn't have any services running by default, and doesn't have a firewall either, i think they consider than a sane compromise 19:35 <+catphish> seems like running a simple outbound only fiirewall would be a better default 19:44 < plujon> Routers seem to vary widely in price: $30 vs $90 vs $200. E.g., https://www.newegg.com/Product/Product.aspx?Item=N82E16833320168 is $30, https://www.amazon.com/NETGEAR-Nighthawk-AC1750-Gigabit-Ethernet/dp/B00R2AZLD2/ref=sr_1_3?s=pc&ie=UTF8&qid=1527788176&sr=1-3&keywords=ac+router&refinements=p_72%3A1248879011 is $90 19:45 < DoctorDick> What's your point? 19:46 < DoctorDick> And you're comparing a Wireless N router with AC 19:47 < plujon> N has a lower maximum, right? 19:47 < DoctorDick> https://www.linksys.com/us/support-article?articleNum=135534 19:49 < plujon> I don't anticipate getting anywhere close to 450 Mbps with my current ISP. I anticipate more like 20 Mbps. 19:52 < plujon> With my old router, after awhile, I couldn't get more than 7 Mbps. But I don't know the reason. 19:53 < plujon> It was a Buffalo router, circa 2011, with DD-WRT installed. 19:55 < coogle> Hello all! Can someone please help me with a networking issue I'm trying to solve with my DD-WRT router? 19:55 < coogle> I'm not very good with routing tables and I'm so close to getting this stupid thing working! 19:55 <+catphish> plujon: pretty much any router will do if your internet speed is that slow, but more expensive routers will likely have better reliability and wireless range too 19:56 < coogle> My problem is this: My DD-WRT router seems to have a bug where if I change the WAN connection from the default to my tethered cellular modem (vlan2 to eth4), the whole system crashes. It looks like it's botching the routing table up and everything dies 19:57 < coogle> If I manually do a "route add default gw 192.168.2.1 eth4" and "route del default gw 172.16.0.1" I can ping 8.8.8.8 from the router 19:57 < coogle> (as in when I ssh into the router I can ping the IP) 19:57 < coogle> but I can't ping the IP from a computer connected to the router via WiFi 19:57 < coogle> thoughts? 20:01 <+catphish> coogle: you likely need to add a NAT (masquerade) rule on eth4 20:01 < coogle> catphish: can you help explain? Networking was never my strong suit lol 20:02 <+catphish> coogle: first of all, don't use dd-wrt, it's an abomination, but since you are, i'll try to help :) 20:02 < coogle> catphish: I'm open to recommendations on that -- I don't have a lot of options however it seems for my router (ASUS AC5300) 20:02 <+catphish> openwrt if possible, it's similar but not proprietary 20:03 < coogle> Doesn't seem supported unfortunately for my router :( 20:03 <+catphish> that's unfortunate :( 20:03 < coogle> Yeah... well you do what you can right? 20:03 <+catphish> coogle: so, your router has an IP address on eth4 20:03 < coogle> Yeah I statically assigned it 20:04 <+catphish> so, when your router sends packets out on eth4, it uses eth4's IP address, and that works 20:04 <+catphish> but... when your PC sends a packet, it uses its own IP address, and the tethered modem doesn't understand that 20:04 < coogle> okay, makes sense. Throws the packet away 20:04 <+catphish> so, if you run: iptables -t nat -A POSTROUTING -o eth4 -j MASQUERADE 20:05 < coogle> it's going to pretend the packet came from my static ip attached to eth4 20:05 <+catphish> this causes all packets forwarded by the router, then leaving eth4 to have their IP rewritten to eth4's IP address 20:05 <+catphish> then the cellular modem will understand 20:05 <+catphish> and know where to send the replies back to 20:05 <+catphish> yes, what you said :) 20:06 < coogle> okay let me give that a shot.. I may drop because I literally have to switch to my router's WiFi that obviously isn't working, ssh in, try this, and then switch back to the hotspot's WiFi ;) 20:06 < coogle> brb 20:12 < coogle> catphish: Not sure my last messages made it through because of the network bounce 20:13 < coogle> but it didn't work, and the MBP is trying to route the packets through what looks like the old and incorrect IP 20:14 < tdoirc> I'm just wondering, would a 1Gbps POE injector work for a 10Gbps link? Considering the difference between 10/100 and 1Gbps POE injection is number of pairs used for data, could 1Gbps POE and 10Gbps POE be the same for injection? 20:15 < coogle_> catphish: Check that! It worked! 20:15 < coogle_> Thank you very much! 20:15 * coogle_ is now on his real LAN connection, routing through his hotspot 20:29 <+catphish> coogle: cool 20:43 < Aeso> tdoirc, I wouldn't bet on it. The modulation scheme is considerably different between gigabit and 10GBASE-T 20:46 <+catphish> why not just use 10GBast-T but slow down time by 10x 20:48 < detha> Now I am wondering what sort of device a) speaks 10GBase-T and b) needs PoE. 20:48 < Aeso> detha, any wave 2 WAP could potentially qualify 20:50 < detha> heh, show me any wave 2 AP that practically does over 1Gb/s outside the faraday-cage lab 20:50 <+catphish> not many wifi devices run at more than 1Gbps, but something like an airfiber might 20:50 <+catphish> https://www.ubnt.com/airfiber/airfiber24-hd/ 20:51 < detha> can't remember offhand, but I would expect that to draw more than standard PoE can supply 20:51 <+catphish> probably 20:51 < Aeso> detha, MU-MIMO makes that more likely than you might think. I've seen a Wave 2 WAP with 4 3x3 clients saturate a gigabit uplink in the wild 20:52 < ryao> detha: Unifi AC HD 20:52 < E1ephant> a single AP, in deployment of 1000s? 20:52 <+catphish> most i've ever seen was about 500Mbps 20:52 < E1ephant> yeah not buying it either 20:52 < ryao> A 3 stream client could exceed 1GbE on the Unifi AC HD, although I don't know offhand if it supports better than 1GbE backhaul... 20:53 < E1ephant> as a real req for the real world 20:53 < detha> interesting, AF24 only takes 40W and can run off PoE. Not bad. 20:53 < ryao> It doesn't. It just supports LACP. 20:53 <+catphish> detha: the spec i'm reading says 50W 20:54 < E1ephant> do solar : 20:54 < E1ephant> :P 20:54 < ryao> This one does though: https://ruckus-www.s3.amazonaws.com/pdf/datasheets/ds-ruckus-r720.pdf 20:54 < detha> catphish: I looked ar the datasheet from the link you posted 20:54 < detha> *at 20:54 <+catphish> https://dl.ubnt.com/datasheets/airfiber/airFiber_DS.pdf 20:54 < ryao> They use the same radio chip. 20:54 < Aeso> EIRP for non-licensed devices is capped at 36dBm (4W), no? 20:55 < ryao> The airfiber is fairly amazing, but it does not exceed 1Gb/s duplex. 20:55 <+catphish> Max. Power Consumption 50W Power Supply 50V, 1.2A PoE GigE Adapter (Included) 20:55 < ryao> Aeso: I recall reading that directional devices are allowed to go higher. 20:55 <+catphish> Data Port (1) 10/100/1000 Ethernet Port 20:55 < Aeso> if your antenna gain is even 6DBi you should only need a 1W transmitter, which you should be able to drive will less than 10W 20:55 <+catphish> so i assume their 2Gbps claim is duplex 20:56 < detha> Aeso: it's not only RF you need to feed, DSPs are power-hungry beasts 20:56 <+catphish> the raw throughput is 1500Mbps each way, so after overhead i guess it aims to saturate 1Gbps each way 20:57 <+catphish> impressive, but still only 1Gbps :) 20:57 < Aeso> detha, for sure, especially at the higher modulation schemes. 20:57 < ryao> High power output is needed to support high order modulations over long distances. The directional antennas do not replace the need for that after a certain distance and amount of obstructions. 20:57 < ryao> Aeso: You beat me to it. 20:58 < ryao> detha: You can control the power output, so if you don't need high power output, you don't need to use it. 20:58 <+catphish> "airFiber AF-24HD" claims 2000Mbps raw throughput, but still only has 1 x 1Gbps port 20:58 < Aeso> don't forget fresnel zones, etc etc 20:58 < Aeso> tl;dr point to point wireless communications is some complicated shit 20:58 < ryao> catphish: That is because it is duplex. It uses 2 different frequencies simultaneously. 20:58 < ryao> One is RX and the other is TX. 20:59 <+catphish> ryao: you're right, 2000 Mbps = 2 x 100 MHz channels 20:59 < ryao> catphish: I remember reading up on these a while back out of curiosity. 20:59 <+catphish> "* Aggregated capacity in Full-Duplex mode" 20:59 <+catphish> so yeah, i was mistaken, its 1Gbps each way 21:00 <+catphish> which is really quite impressive, as i suspect they actually achieve that over significant distances 21:00 < ryao> catphish: They reportedly do. 21:00 < ryao> catphish: The Ruckus Zoneflex R720 should be able to sustain >1Gbps speeds over wireless, although only in special cases, like only 1 client using bandwidth. 21:01 <+catphish> ryao: i did an install with high end ruckus, can't remember the model, it sustained 500Mbps under "normal" conditions, ie from a pole to a laptop on a beach nearby 21:02 <+catphish> which i thought was very impressive 21:02 < ryao> catphish: It was likely the R700. 21:02 <+catphish> sounds familiar 21:03 < ryao> catphish: I have the R710, which does like 610Mbps from a laptop. The R720 has the same chip as the Unifi AC HD, which can do amazing throughput. 21:03 <+catphish> nope, wasn't r700 21:03 <+catphish> i'll have a look 21:03 < ryao> catphish: Wait... A pole? The T700 I guess. 21:03 < ryao> The R series is indoor. 21:04 <+catphish> yes, it was T700 or T710 21:04 < ryao> It sounds like the T700 given that my R710 outperforms it. 21:04 <+catphish> it was about 4 years ago, so whatever was current then 21:04 <+catphish> T700 seems likely 21:04 < ryao> Anyway, the QCA9994 Wi-Fi radio chip is amazing in terms of link efficiency. I have no idea how qualcomm did it. 21:05 <+catphish> qualcomm have a time machine, they just bring tech from the future and sell it 21:05 < ryao> catphish: Well, it is the future. :P 21:05 <+catphish> i used to work there, i'm not supposed to tell anyone 21:05 < ryao> catphish: Did you work for them? 21:05 <+catphish> yep 21:06 < ryao> This isn't part of the future joke, is it? 21:06 <+catphish> https://uk.linkedin.com/in/charliesmurthwaite 21:06 < ryao> Cool. 21:07 <+catphish> i was in their internet division though, didn't have anything to do with their main radio tech 21:09 < ryao> This should be a fairly amazing radio for either an AP or a client: https://www.compex.com.sg/product/wle1216v5-20-i/ 21:10 < ryao> It is cheap enough off eBay that you could likely get a routerboard and save money given the premium that Ubiquiti charges... 21:11 <+catphish> yes that is a nice radio 21:11 <+catphish> how many money? 21:12 < ryao> catphish: I found it for $90: https://www.ebay.com/itm/like/253574681468 21:13 < ryao> The listing has an error though. It claims it has the QCA9984, but the manufacturer says the QCA9994: https://www.compex.com.sg/product/wle1216v5-20-i/ 21:13 < ryao> These only cost $80: https://mikrotik.com/product/RB912UAG-5HPnD 21:13 < lumake> hey two days ago my PXE server started acting funny and attemts at ssh'ing into it would time out as well as clients tring to boot from it would time out. the issue comes and goes and i'm having trouble diagnosing it. i was wondering if anyone had any ideas as to how i should go about troubleshooting this issue? 21:14 < detha> lumake: logfiles, dmesg 21:15 < lumake> dmesg doesn't seem to show anything of interest 21:15 <+catphish> lumake: bonded ethernet? 21:15 < lumake> sorry, im a bit of a noob when it comes to the terminology 21:16 < lumake> yes it's ethernet 21:16 <+catphish> a normal physical server? 21:16 <+catphish> does it have just one network connection? 21:16 < lumake> yes just one network connection 21:16 <+catphish> ok 21:17 < lumake> it's a "server" only iin the sense that is running server-ish software 21:17 < lumake> heh. 21:17 < detha> lumake: for how long does it disappear each time? 21:18 < lumake> hrm, i haven't timed it... but it's definitely more than 5min 21:18 <+catphish> the first debugging step would be to see if you can ping it when it's otehrwise unresponsive 21:18 < lumake> i can't even ping the darn thing 21:18 < lumake> yah , can't ping it 21:18 <+catphish> this will tell you if its a connection problem, or a problem with the services 21:19 <+catphish> ok, so it's a network connectivity problem 21:19 <+catphish> ideally you want to get a local console on it 21:19 < detha> try with arping, to see if it is a duplicate IP 21:19 <+catphish> so you can do debugging locally when its unresponsive 21:21 < detha> if it was cable or other L1 stuff I would expect interface up/down messages in dmesg, so L2/L3 21:22 <+catphish> i'd get tcpdump running on it on a local console 21:22 < detha> what happened 2 days ago? any kernel updates or something like that? 21:22 <+catphish> and observe when its broken 21:23 <+catphish> detha makes a good point 21:23 < lumake> ok, i'll describe the network a bit. i have a cable modem/router that feeds a wireless router for the wifi in the lab. the PXE server is connected via ethernet to the modem as is the wifi router. 21:23 < lumake> dertha no idea, no updates as far as i know, i checked file changes and there was nothing 21:24 < detha> do you have anything else connected via ethernet you can check from? 21:24 < lumake> the PXE server is on 10.1.10.1/24 and everything that connects to the wifi AP is on 10.0.0.1/24 21:24 < lumake> i USED to be able to connect to wifi and ssh into the PXE server without issue 21:25 < lumake> now , since two days ago , i'm getting these weird timeouts 21:25 < lumake> the networking is not optimal since i am noobish 21:26 < detha> what routes between those two ranges? 21:26 <+catphish> " the PXE server is connected via ethernet to the modem as is the wifi router." that's a very odd config 21:27 < lumake> heh. 21:27 < lumake> the wifi-router-AP is just to provide wifi for the lab 21:27 <+catphish> why does the router even have a private IP on the WAN side? 21:28 < lumake> the modem-router does not have wifi 21:28 < lumake> i need wifi in the lab so i attached a wifi-router-ap 21:29 <+catphish> oh, i missed that, the modem is also a router 21:29 < lumake> yes 21:29 <+catphish> so you have 2 levels of NAT 21:29 < lumake> yes 21:29 <+catphish> that definitely should work fine 21:30 < lumake> do you have any suggestions what log file i should check first or what to grep for? 21:30 < lumake> dmesg comes up empty for anything "obvious" 21:30 <+catphish> can you ping the server from other network? 21:30 < lumake> yes when it's not hung up on whatever it's hanging up on 21:30 <+catphish> ie the 10.1.10.1/24 network 21:30 <+catphish> i meant when it was crashed 21:31 <+catphish> or can you not ping it from anywhere? can it ping out to the internet? 21:31 <+catphish> you need to catch it when its broken 21:31 < lumake> i can ping the wifi-router-ap which has a 10.1.10.1/14 addy 21:31 <+catphish> and see what (if any) connectivity it does have 21:31 < lumake> yea i can ping eveyrthing exept the pxe server 21:32 <+catphish> when its broken 1) can you ping the pxe server from anywhere at all 2) can you ping out to the internet from the pxe server 21:32 < lumake> so when it's hanging up, i go to the pxe server and try to ping a WAN addy/website and there are no issues 21:32 < detha> does the PXE server have its address set statically? 21:32 < lumake> yes 21:32 <+catphish> so it *can* connect out, but nothing can ping it from either network? 21:33 < lumake> yes 21:33 <+catphish> that's strange 21:33 < lumake> wait 21:33 < detha> does it runs things like fail2ban? 21:33 < Windy> anyone use aruba IAPs ? is it possible to send syslog via the VC address rather than each individual IAP address? 21:33 <+catphish> feels like firewall if it can connect out, but things can't connect in to it 21:33 < lumake> machines that have been served from the PXE server CAN ping it even if it's unaccessible from other locations 21:33 < lumake> detha no 21:34 <+catphish> this makes surprisingly litte sense 21:34 < detha> ARP issues, duplicate IP or something like that 21:34 < lumake> catphish, that's what's making me confused as well 21:34 <+catphish> all clients on the 10.0.0.0/24 network will all appear to the the same client, since they are NAT'd 21:34 < detha> things that have its MAC still work, but ARP fails 21:34 <+catphish> detha: but there's a router in between 21:35 < detha> true 21:35 < lumake> oh forgot to mention the pxe server get's it's connectivity from a dumb switch that's directly connected to the modem-router 21:35 <+catphish> that doesn't matter (hopefully_ 21:35 <+catphish> ) 21:35 < detha> weird indeed 21:36 < lumake> so it goes modem-router->switch->PXE server 21:36 < detha> what else is on that switch? 21:36 < lumake> PXE server's clients 21:36 <+catphish> to clarify, some clients on 10.0.0.0/24 can ping it, and others can't? 21:37 < lumake> when it's gummed up nothing on 10.0.0.0/24 can ping it 21:37 < lumake> everything on the switch can ping it 21:37 < lumake> afaict 21:37 <+catphish> oh, well that's a bit different! 21:37 < detha> quite so. 21:37 <+catphish> that makes more sense 21:37 <+catphish> maybe it's firewalled the NAT IP 21:38 <+catphish> or the router IP is duplicated 21:38 < detha> that would make sense 21:38 < lumake> the router ip is 10.1.10.13 and pxe is 10.1.10.12 (static) 21:38 < lumake> the wifi-router* 21:39 < lumake> the modem-router = 10.1.10.1 21:39 < detha> when it is broken, can you still ping 10.1.10.13 from 10.0.0.0 ? 21:39 < lumake> hold on , i have to wait for it to break XD 21:40 < lumake> shouldn't be long lol 21:40 < detha> when it breaks, try traceroute, see if you can still ping modem/router from 10.0.0 21:41 < detha> also, if there is some form of diagnostic on that modem/router, see if you can ping the PXE server from there 21:50 < lumake> great. now when i want to diagnose it decides to behave. 21:53 < lumake> so i can ping to the server from the 10.0.0.0 net but i can't ping FROM the server to the 10.0.0.0 net 21:53 < GoopAway> I want to run some sort of peer-to-peer network between me and my friend, so we can send data without an ISP. 21:55 < GoopAway> I've seen some yagi antennas talked about online and they're supposed to go for a few miles. There's about 4/5 miles between us (direct), but there's some city in the way. We don't have man you tall buildings in the city 21:55 < GoopAway> Many tall* 21:55 < GoopAway> Would it be possible? 21:56 < lumake> also , i can not ping the wifi-router-ap (10.1.10.13) from the PXE server (10.1.10.12) 21:56 < phocking> GoopAway: a direct line of sight is the most important thing for wireless links 21:56 < lumake> it just hangs 21:56 < phocking> if you have a perfect shot you can hit 8-10km with a 400mw integrated device 21:57 < phocking> if you have 'some city/trees in the way' that can very quickly become less than half a km 21:58 < GoopAway> phocking: is that with both send/receive using yagi antennas? 21:58 < phocking> nobody uses yagi for 2.4 21:58 < phocking> do you have a line of sight? 21:59 < GoopAway> No, I do not. I might be able to, if I can mount something on some tall poles. 21:59 < phocking> i mean some people do im sure, but they really shouldnt; an integrated panel antenna will get you more bang for buck. a yagi is for painting a wider area 22:00 < GoopAway> Oh, I thought yagi gave you directional benefits. 22:02 < Harlock> it does 22:03 < Apachez> https://github.com/teslamotors/linux 22:05 < godSend23> hey all 22:09 < godSend23> is GCP a bit overboard for hosting a site? 22:11 < tdoirc> Aeso: I haven't been able to find any resources that state one way or another for POE unfortunately, and it doesn't seem like there are very many, if any, 10Gbps POE injectors (I haven't been able to find anything) 22:14 < godSend23> ?? 22:16 <+catphish> ?? 22:17 < Aeso> ?? 22:17 < DoctorDick> ?? 22:18 < godSend23> should I use GCP for hosting? 22:18 < Aeso> godSend23, that's a _really_ open-ended question 22:18 < Aeso> here's a really open-ended answer: maybe 22:18 < Aeso> :) 22:19 < godSend23> i mean is there OS that has AI and ML too? 22:20 < Aeso> firstly, GCP isn't an OS? 22:20 < Aeso> secondly, your website needs ML to operate? 22:20 < qman__> Hosting a site and machine learning are two completely different things 22:22 <+catphish> should i use a donkey to ride into town? 22:23 < godSend23> it doesn 22:23 < godSend23> doesn't 22:23 < godSend23> but it'd be nice to have 22:23 < godSend23> uder the hood 22:24 < DoctorDick> I don't think you know what those are 22:24 < godSend23> i think 'light' suggested GCP to me 22:24 < godSend23> b/c of it's vast features 22:38 < TwoIce> Hi. Anyone know about any proxy/tunnel that obfuscates the traffic to look like html (no tls)? 22:42 < qman__> Machine learning is not an "under the hood" feature 22:43 < qman__> Your wordpess blog is never going to ytilize machine learning 23:31 < subunit> will HFC networks ever compete with fiber in the future? 23:41 < TandyUK> as in cable? not a chance 23:42 < TandyUK> what do you think the majority (if not all) cable networks use for their backhaul? 23:43 < S_SubZero> I didn't understand the question 23:44 < S_SubZero> HFC is "fiber is part of the run, copper is another part of the run". The fiber part of HFC is... fiber! 23:44 < TandyUK> right, so compared to pure fibre end to end, theres no contest 23:45 < Aeso> unfortunately CMTSes are here to stay, at least for the next 10-15 years 23:45 < TandyUK> pure fibre will always be faster (speed or latency) than anything involving copper 23:45 < Aeso> tbh it's pretty incredible how much bandwidth you can stuff down 40 year old coax 23:46 < TandyUK> what pisses me off, if the virgin media adverts on UK tv, talking about their "super fast fibre broadband", all the while showing a fucking coax cable on the screen 23:46 < S_SubZero> my wiring is from the 70s and handles 175Mbit down without issue 23:46 < TandyUK> at least BT dont mislead people, by naming it "Fibre to the Cabinet" (not your house) 23:49 < Aeso> if you look at the modulation scheme, DOCSIS 3.1 really should have been DOCSIS 4 23:49 < Aeso> 2 to 3 was a smaller change than 3 to 3.1 23:51 < Aeso> 3.1 will do QAM-1024 on the same SNR that 3.0 required for QAM-256 due to improved FEC 23:52 < Aeso> plus the channel bandwidth shrunk significantly while the total range grew, meaning more customers on the same CMTS 23:52 < Aeso> more bandwidth more better :) 23:54 < koala_man> subunit: yes, they're way cheaper in the near future 23:54 < TandyUK> hmm thats not my experience of customers actually using it 23:54 < TandyUK> latency went up, overall reliability went down, pretty much 23:54 < TandyUK> assuming virgin went from 3 to 3.1 whe nthey started doing their "up to 300mb" services 23:54 < badsekter> if someone gets your ip (because you visit their website say) can they hack your home network by changing your router's dns or something? 23:55 < mr_sm1th> So I asked my domain registrar to set glue records. My nameserver is at ns1.box.domain.net, but the registar set the glue record to ns1.box with the ip. 23:55 < TandyUK> badsekter: if your home router security is horrifically bad, sure 23:55 < mr_sm1th> Shouldn't it be ns1.box.domain.net? 23:55 < TandyUK> mr_sm1th: why on a subdomain? 23:56 < TandyUK> ie why not ns1.domain.net 23:56 < varesa> badsekter: IPv4 address space is small enough that it's constantly being scanned and "attacked" 23:56 < TandyUK> you know what glue records are used for right?? 23:56 < badsekter> tandyuk, not by remote admining, but by teaching it a false dns server 23:56 < mr_sm1th> TandyUK, That's just the way it is. 23:56 < TandyUK> mr_sm1th: WHY is that "the way it is", its stupid imho 23:56 < mr_sm1th> TandyUK, It's used so that I can use my own nameserver for the domain of the nameserver itself. 23:57 < mr_sm1th> TandyUK, It's not relevant. 23:57 < TandyUK> right, but the domain of the nameserver isnt a domain, its a sub domain 23:57 < Aeso> TandyUK, 'up to 300mbps' was what we got with DOCSIS 3 here. Not sure what virgin is doing. 23:57 < varesa> badsekter: you can't teach devices DNS servers outside the ISP network (and even then only if it uses DHCP for DNS servers) 23:57 < mr_sm1th> TandyUK, Correct. 23:57 < varesa> the attacker would have to be between the ISP and you 23:57 < TandyUK> you answering your own question yet? 23:57 < TandyUK> and it should be ns1.box.domain.net. 23:58 < TandyUK> but what then resolves "box.domain.net"? 23:58 < TandyUK> what are the nameservers for that? 23:58 < mr_sm1th> TandyUK, ns1.box.domain.net 23:58 < TandyUK> urgh 23:59 < TandyUK> ok, so you set glue records for "domain.net." 23:59 < mr_sm1th> Yes. 23:59 < mr_sm1th> I set ns1.box.domain.net and as a glue record. 23:59 < TandyUK> stop usign a damn subdomain 23:59 < mr_sm1th> But they set ns1.box and as a glue record. 23:59 < TandyUK> box.domain.net is the host --- Log closed Fri Jun 01 00:00:16 2018
