[10:59] <TwistedLucidity> Hi. Can anyone point me towards current documentation on how to configure two networks in Ubuntu (desktop, if that makes any odds)?
[11:00] <TwistedLucidity> Network 1 has Internet, Network 2 does not. As soo as Net#2 is attached, I lose Internet, DNS resolution etc; despite having routing info, multiple DNS servers all supplied.
[11:00] <TwistedLucidity> To my inexperienced eyes, routing table looks fine so I have no idea what is wrong.
[11:05] <BigRedS> can you ping hosts on either or both networks when you lose internet?
[11:26] <TwistedLucidity> Yes, ping is fine
[11:26] <TwistedLucidity> I can ping Internet by IP as well.
[11:26] <TwistedLucidity> Name resolution goes down the toilet
[11:27] <TwistedLucidity> It's as if the local systemd dnsmasq instance (or whatever is used these days) refuses to check the DNS servers on each networkin turn.
[11:28] <TwistedLucidity> "dig thing @network-1-dns" and "dig thing @network-2-dns" both work too
[11:37] <TwistedLucidity> "/etc/resolv.conf" lists the various search domains from the two networks and 127.0.1.1 as the nameserver, which AIUI is the thing systemd runs.
[12:05] <NET||abuse> i'm not sure i get managing btrfs, i have a home NAS running 16.04, and i have 4 x 6TB disks in a btrfs array
[12:05] <NET||abuse> i followed some basic wiki's to install, so not really super confident in my understanding, problem is it's been running for over a year in this setup without much monitoring or management
[12:06] <NET||abuse> ive got graphics work, apps, disk images, media backups and music on here, but i've no idea how much space is really used.
[12:07] <NET||abuse> if i do `btrfs filesystem df /mnt/data -h`   i get a few lines, but Data, RAID1: total=4.79TiB, used=4.79TiB  makes me nervous
[12:07] <NET||abuse> System, RAID1: total=8.00MiB, used=688.00KiB    Metadata, RAID1: total=7.00GiB, used=5.63GiB
[12:09] <NET||abuse> if i do `btrfs filesystem show`  i gegt 4 disks listed as  /dev/sd[a,b,c,d]    all of them say   size 5.46TiB used 2.40TiB
[12:12] <BigRedS> TwistedLucidity: what does    ip a s    say? it sounds like your networking's working but you've no default gateway
[12:12] <BigRedS> not ip a s,    ip r s
[12:12] <BigRedS> the routes
[12:34] <diddledan> BigRedS: did you have a spasm? ip r s, ip a s <-- looks rather random :-p
[12:35] <BigRedS> :)
[12:35] <BigRedS> I wasn't taken at all by this ifconfig->ip switchover until I realised you can abbreviate everything to single letters
[12:35] <BigRedS> but, yeah, that's `ip all show` and `ip route show` in longer-form
[12:35] <diddledan> nice
[12:37] <BigRedS> also, you can do `ip route get <ip address>` to see the route out for that address, which is neat
[12:44] <diddledan> cyber, cyber, cyber! https://www.wired.com/story/russian-hackers-attack-ukraine/
[12:44] <zmoylan-pi> you'd think by now the ukraine would air gap... everything...
[12:48] <TwistedLucidity> BigRedS: starts witl "default via ip-range-#1 dev nic#1 ...."
[12:49] <TwistedLucidity> Then there's three ip ranges for nic2 (which look correct)
[12:49] <TwistedLucidity> An odd looking ip range for nic#2 (related to loop-back or this being a VM?)
[12:49] <TwistedLucidity> And finally, the main ip range for nic#1
[12:50] <BigRedS> er, so your default route is to go out of the interface you think it ought to be, and to go via the gw you think it shoudl be, and nothing following contradicts that?
[12:50] <TwistedLucidity> As far as I can see, yes. Bear in mind, I am terrible at networking.
[12:51] <TwistedLucidity> I think this might be a failure with systemd. Not sure.
[12:51] <BigRedS> most things are :)
[12:51] <diddledan> that's an odd image to put against "introduction to functional programming in javascript" https://twitter.com/opensourceway/status/879683492262670336
[13:24] <TwistedLucidity> Just tried a fresh Xubuntu install; exact same issue. Shame I can't seem to find any current documentation :-(
[15:20] <diddledan> https://twitter.com/holly/status/879720003288924160
[15:21] <zmoylan-pi> i only watched that movie for the first time after bowie died...
[15:51] <TwistedLucidity> Ah, BigRedS has gone just as I cracked it.
[15:52] <TwistedLucidity> To get multiple NICs working you have to install dnsmasq and then manually hack away at /etc/dnsmasq.conf Very strange.
[16:22] <diddledan> this is an intriguing bug in the Intel Microcode: https://lists.debian.org/debian-devel/2017/06/msg00308.html
[16:25] <TwistedLucidity> diddledan: It'd be funny if it wasn't so serious
[16:27] <diddledan> it's crazy it's taken this long to figure out there's a bug, find the reason, and fix it - I guess most folk just chalked up any errors as transient and/or "well that was weird" and moved onto other things
[16:29] <diddledan> by the way they describe it as being hit when a loop is executed that has fewer than 64 commands it sounds to my untrained eye that it might be due to context switcheroos hapenning before the other thread on the same cpu is able to accept it's changing
[16:31] <diddledan> of course, the fact that I'm tring to "hear" with my untrained "eye" suggests that I'm gonna be very wrong due to the premise that eyes aren't for hearing with
[16:32] <diddledan> bah, burger off then!
[16:32] <diddledan> :-p
[16:32] <diddledan> they got hit by the bug :-D
[18:48] <diddledan> aww, poor kitty: https://twitter.com/JimMFelton/status/879459351236399106
[18:55] <foobarry> still getting spinny wheel on iplayer on linux. working on android. anyone else?
[18:55] <foobarry> on all progs, e.g. http://www.bbc.co.uk/iplayer/episode/b01qxms3/storyville-the-pirate-bay
[21:09] <diddledan> the original Blomkvist died :-( https://twitter.com/suziperry/status/879808132679180288
[21:10] <diddledan> (Girl with the Dragon Tattoo reference)
[21:19] <zmoylan-pi> hardware problems... :-P http://www.scmp.com/news/china/society/article/2100242/elderly-flight-passenger-throws-coins-engine-luck-delays-take?utm_content=buffer90c8d&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer
[21:33] <diddledan> moron
[21:36] <zmoylan-pi> one of the first pcs i had to repair was been used as a point of sales in a video library in the 80s... a newbie had been shoving money into the floppy drive... and other gaps
[21:38] <brobostigon> i have seen other similer gaffs with machines like that, people trying to put objects into computers where they dont belong.
[21:40] <zmoylan-pi> i remember one customer saved a few bob by having an electrical engineer install new hard drives... he used a rivet gun to secure them... i used to have a pic with a few rivets i found rolling around in base of case when it failed
[21:42] <brobostigon> i would like to have seen that.
[22:09] <diddledan> brobostigon: zmoylan-pi : isn't putting things into a pc another word for cyb0rsecks?
[22:10] <diddledan> wow. rivet gunning an HDD sounds... interesting
[22:13] <brobostigon> when i was at college, we have a power supply explode in our faces, not our fault, the the power supply was faulty, but it set off half the buildings smoke alarms and emptied half the building.
[22:13] <brobostigon> we had*
[22:31] <diddledan> nice! https://twitter.com/AshleyEsqueda/status/879821023675203584
[22:31] <diddledan> now if only we could embed that directly into our visual cortex
[23:01] <diddledan> so apparently today's ransomware is using the same eternalblue exploit as wannacry. why didn't everyone update their systems to block this is beyond me!?!
[23:40] <zmoylan-pi> the last one didn't affect us, we must be safe!
[23:54] <diddledan> interesting point that it only takes a single vulnerable system to compromise an entire windows-based network: https://twitter.com/mikko/status/879742221326721028
[23:55] <zmoylan-pi> one nutter bringing in a laptop from home will do the trick.
[23:55] <diddledan> WMIC and PSEXEC are remote administration things that allow the compromised system to use the current user's credentials (or other credentials if supplied directly) to execute code on other PCs
[23:56] <diddledan> e.g. if an AD administrator gets caught then his creds can be used to pwn the entire network
[23:57] <diddledan> even lowly users will probably have some form of access to most desktops so it'll pwn the fleet of user-level PCs no matter what
[23:57] <diddledan> zmoylan-pi: BYOD!
[23:57] <diddledan> Bring Your Own Device^H^H^H^H^H^HDoomsday-weapon
[23:57] <zmoylan-pi> they make take my data, but they'll never take my nokia!!
