| drab | I get the million <3 | 00:24 |
|---|---|---|
| drab | it seems like if I disable predictable then the matching in udev is screwed up, don't have the time to debug why, but I can'tg et eth0 to become "lan" | 00:24 |
| drab | so if I make the names "predictable" again, and I will quote "predictable" to my death bed because it's the last thing those names are, the you can match with KERNEL="enp*" | 00:25 |
| drab | that seems to avoid the bridge device which wuoldn't match and therefore it all works in the end | 00:25 |
| drab | mega workaround but worth a million. at some point that systemd bug will make it through and it'll "just work" [tm] | 00:26 |
| OerHeks | drab, maybe this works, mask udev's rule file for the default policy: ln -s /dev/null /etc/udev/rules.d/80-net-setup-link.rules >> https://www.shysecurity.com/post/20160510-Ubuntu%20Network%20Interfaces | 00:30 |

| drab | OerHeks: that post itself says that method doesn't :) | 00:39 |
| drab | anyway it's fixed per above | 00:39 |
| drab | I'm gonna go enjoy the million dollar :P | 00:39 |
| drab | certainly hard earned | 00:40 |
| OerHeks | oh | 00:42 |
| DirtyCajun | Do we have a stable kernel release that works with AM4 ? | 02:07 |
| DirtyCajun | Reading the release notes it looked like 4.10 was promising but i wanted some opinions | 02:07 |
| sarnold | DirtyCajun: I suspect most folks just use xeons. You may have better luck in #ubuntu | 02:08 |
| DirtyCajun | That is the pleb channel. i stay far away | 02:10 |
| sarnold | hehe | 02:11 |
| DirtyCajun | Xd | 02:11 |
| patdk-lap | I dunno why you don't ask in the kernel channel | 02:11 |
| sarnold | I just figured it'd be more likely a gamer would know.. | 02:11 |
| DirtyCajun | Wat. its not for gaming | 02:11 |
| DirtyCajun | its a 16 thread proc. its for my plex 2u | 02:11 |
| patdk-lap | heh? not for gaming? | 02:11 |
| sarnold | oh? I thought this was the new amd cpu; the only other person who's mentioned it on irc is a gamer.. | 02:11 |
| patdk-lap | dunno what an AM4 even is | 02:11 |
| patdk-lap | people use amd in servers? | 02:12 |
| DirtyCajun | absolutely | 02:12 |
| patdk-lap | never seen one, ever | 02:12 |
| DirtyCajun | wel.... i work at a datacenter | 02:12 |
| DirtyCajun | and it is in about 40% of our blades | 02:12 |
| patdk-lap | I have racks of servers, not a single amd | 02:13 |
| sarnold | well what do you know, an amd chip in a server ;) http://www.thinkmate.com/system/stx-nl-qe12-2210 | 02:13 |
| patdk-lap | :) | 02:13 |
| patdk-lap | they are always horrible for my performance workload, due to the lack of ondie l2 cache that intel has | 02:13 |
| DirtyCajun | patdk-lap, check out the specs of the Ryzen | 02:13 |
| DirtyCajun | and the upcoming server grade chips | 02:13 |
| patdk-lap | ya, I'll wait for real benchmarks | 02:14 |
| drab | why is mdadm and preseeding such a pain to work with :( | 02:14 |
| patdk-lap | as the benchmarks so far, are not accurate | 02:14 |
| DirtyCajun | passmark has 50+ | 02:14 |
| sarnold | in fairness it's insanely hard to do benchmarking well | 02:14 |
| patdk-lap | the last benchmk I saw of amd new cpu line was, in this specific memory workload test, we beat the crap out of intel | 02:15 |
| patdk-lap | due to having double the amount of memory channels | 02:15 |
| patdk-lap | ya, anyone can make something beat the crap out of something else in one area, I want to know about normal workloads :) | 02:15 |
| sarnold | gah | 02:17 |
| sarnold | so, cpubenchmark.net numbers on it look pretty good but I was curious about other specs.. and was looking for an ARK link. sigh. :) | 02:17 |
| patdk-lap | I guess for a in memory database, that might be ok, if the ondie cache is acceptable to actually run the sql server | 02:17 |
| patdk-lap | hehe | 02:18 |
| patdk-lap | I'll wait a year or two atleast | 02:18 |
| drab | how si there not an option to nuke everything with preseed? just nuke, *everything*, don't try to mount raids and be smart | 02:19 |
| patdk-lap | intel has pretty much deadended their cpu lines though | 02:19 |
| drab | have I missed it? | 02:19 |
| drab | I keep getting crap because some of the disks had raid stuff on it that apparently mdadm --zero-superblock hadn't cleaned and install fails | 02:19 |
| drab | and it seems non-sense since I don't care what's on the disks, I just want the whole thing to be wiped and reinstalled | 02:19 |
| sarnold | patdk-lap: what I could find on the amd website is sorely thin on specs, but it does say for the eight core model, 2 channels of ddr4, 768kb of l1, 4mb l2, 16mb l3; 95W | 02:26 |
| patdk-lap | seems light | 02:26 |
| patdk-lap | man, have to go all the way down to a e5-2620v4 to find an 8core intel | 02:28 |
| patdk-lap | 20mb cache | 02:28 |
| patdk-lap | not as bad as it used to be | 02:29 |
| sarnold | I've got a e5-2630v3, very similar specs; but four memory channels, 40 PCIe lanes (instead ofthe 24 that other news sites were reporting for the ryzen) | 02:29 |
| patdk-lap | 4 memory channels | 02:29 |
| sarnold | so says ark, hehe :) | 02:30 |
| patdk-lap | so says my m otherboard :) | 02:30 |
| patdk-lap | so it *might* be comparable | 02:30 |
| patdk-lap | have to see what pricing turns out to be | 02:31 |
| sarnold | cpubenchmark said it'd be a bit cheaper than my cpu | 02:31 |
| sarnold | if you had compute-bound tasks rather than memory bound tasks, the ryzen might be a good fit | 02:31 |
| patdk-lap | ya, most workloads are memory issues | 02:32 |
| patdk-lap | except stuff like encoding video | 02:32 |
| patdk-lap | I don't know why that isn't memory bound, as I would think it should be :) | 02:32 |
| sarnold | it's nice to know amd's in the game again | 02:33 |
| patdk-lap | intel did take themselves out of it | 02:33 |
| patdk-lap | been years since they made progress | 02:33 |
| patdk-lap | and now they basically admitted to giving up | 02:33 |
| sarnold | they haven't had any real need | 02:33 |
| patdk-lap | sure they have | 02:33 |
| patdk-lap | they have almost let arm overrun them | 02:34 |
| sarnold | back in early opteron days | 02:34 |
| sarnold | but it's been a decade | 02:34 |
| patdk-lap | intel is getting backed into a server cpu corner | 02:34 |
| patdk-lap | with this, more and more amd systems for desktops, maybe laptops | 02:34 |
| patdk-lap | but more and more laptops are going arm by being replaced with tablets and phones and stuff | 02:35 |

| ybaumy | hi. what can cause something like the following. on vlan 1 iscsi connections work like a charm. on vlan 500 iscsi connections work like a charm. but on vlan 501 iscsi connection are really slow and its a lottery if they work at all | 07:55 |
| ybaumy | there are no dropped packets. no denies on the firewall | 07:56 |
| ybaumy | i dont find anything at all | 07:56 |
| ybaumy | just that its incredible slow | 07:56 |
| ybaumy | all 3 vlans are using the same physical connection | 07:57 |
| ybaumy | the VM that runs vlan 501 has no memory or cpu problems | 07:58 |
| ybaumy | they all run 16.04 latest patches | 07:59 |
| ybaumy | i found the problem | 08:42 |
| ybaumy | fyi there was proxy arp enabled on the firewall for vlan 501 | 08:43 |
| ybaumy | i found that in tcpdump there were no arp requests | 08:44 |
| a8o | Know any tricks for saving shell history as you enter commands? I keep getting connections lost/dropped and i loose my shell history unless i exit normall. | 11:42 |
| hateball | a8o: first hit on google is http://askubuntu.com/questions/67283/is-it-possible-to-make-writing-to-bash-history-immediate | 11:46 |
| hateball | if you keep dropping your connection you may want to consider using mosh | 11:47 |
| a8o | cool thanks. | 11:47 |
| a8o | I use mosh on some systems, but not all can have it. | 11:47 |
| hateball | a8o: true enough | 11:57 |
| TafThorne | Try using screen or tmux on the remote end. Then your shell session will persist even if you loose ssh connection to the remote. | 12:01 |
| a8o | never heard of tmux. | 12:01 |
| a8o | i do use screen alot, but some terminal apps get all screwy when I use them in screen. But I do use screen for stuff I need to run and watch now and then. | 12:02 |
| TafThorne | tmux is very similar to screen. Their use to be use case differences between then but now days I think both can do pretty much everything the other can do. screen is often already installed on systems (just because it was around first I think). | 12:03 |
| TafThorne | As long as you do not resize the terminal I usually find things behave OK inside screen. I do not use tmux so I cannot vouch for it. | 12:04 |
| a8o | if anything it's fun to try something new. Lately I've been using the fish shell. Love that one | 12:05 |

| jamespage | does that seem familiar to you - I can't get vmware-nsx to build in a PPA | 15:22 |
| jamespage | coreycb: builds fine locally/on a cloud instance using sbuild | 15:22 |
| coreycb | jamespage, haven't seen that before. i wonder if the tests do any db setup that is getting missed for some reason. | 15:24 |
| coreycb | jamespage, i see run_tests.sh has an option to recreate the database | 15:30 |
| jamespage | coreycb: yeah not sure about that | 15:30 |
| jamespage | coreycb: afaict nothing ever gets re-created on disk | 15:31 |
| jamespage | created rather | 15:31 |
| jamespage | coreycb: I lied as well - it failed on my laptop | 15:31 |
| coreycb | jamespage, oh.. | 15:31 |
| drab | anybody here using ansible by any change and has it working with a preseeded install against the in-target chroot? | 15:37 |
| jamespage | coreycb: hmm | 15:59 |
| jamespage | coreycb: I might have it identified | 15:59 |
| jamespage | coreycb: why do we have a patch to make unit tests use an on-disk sqlite db? | 15:59 |
| coreycb | jamespage, is that in vmware-nsx? | 16:00 |
| jamespage | coreycb: no in neutron | 16:00 |
| jamespage | coreycb: disabling it to see if that helps | 16:00 |
| coreycb | jamespage, ok, not sure i'll take a look at it though | 16:01 |
| station | can ubuntu core be used on an intel pc with 4 Etherports as an gateway/rooter … firewall | 16:36 |
| drab | station: I'm doing that | 16:49 |
| drab | actually just getting through the bonding part on a second machine to get a "4gbit" link | 16:49 |
| drab | oh nm, you said core, assumed -server since this is -server, nm | 16:50 |
| station | drab: what did you use to set it up? is it a bad idea to alsow host like security cam directly on the rooter? | 16:53 |
| station | im new to server .... | 16:54 |
| drab | station: if by router you mean your internet modem, it's ok ime as long as you don't open it up and set up, say, port forwarding | 16:55 |
| station | drab: so i could set open sense / pfsense on one "roooter PC" and a separate server | 16:59 |
| drab | <troll level raised to yellow> | 17:01 |
| drab | station: what are you trying to achieve? I'm having troubles to understand what you're asking for | 17:01 |
| drab | are you trying to build a firewall for your home? | 17:02 |
| station | drab: im still learning about server the 4 port pc will replace a slow rooter and I have to get internet access to nextcloud rocketchat … | 17:05 |
| station | was hoping to get them both on one device with ubuntu core but … | 17:09 |
| drab | nacc: you might know, is there any ML I can post to about say preseed questions? ubuntu-server seems to be development list only and not for support requests | 17:20 |
| drab | but I don't see any other place/ML where -server ppl are hanging out to ask a question | 17:20 |
| nacc | drab: you can ask here | 17:25 |
| nacc | drab: you can ask on -server too, you might just get redirected around a bit; i wonder if ubuntu-users is the right place | 17:26 |
| drab | nacc: I doubt -users deal a lot with preseed, feels like asking in ubuntu-desktop :P | 17:30 |
| drab | but maybe I'm wrong, not on -users | 17:30 |
| nacc | drab: what's your question? | 17:30 |
| drab | nacc: if you don't think -server ppl are going to hate me for the rest of my life for posting support requests to a -devel list then I'll try that | 17:31 |
| drab | I have two preseed problems | 17:31 |
| drab | both on -server and -desktop actually, altho latetr may be a bug in ubiquity installer | 17:31 |
| drab | so on -server, I can't figure out how to get preseed to ignore everything on the drive | 17:31 |
| drab | if I try to re-pxe a sytem that had raid on it, initrd I think will autostart the md device | 17:32 |
| drab | by the time parted kicks in the drives are in use and everything fails because there's no root device | 17:32 |
| nacc | pxe doesn't depend on a physical device being present for root | 17:32 |
| drab | I have to manually get a shell, mdmad --zero-superblock, stop the mdadm device, and then dd zeros for good measure | 17:33 |
| drab | sure, talking about preseed | 17:33 |
| drab | I can't basically reinstall a system automatically as it stands | 17:33 |
| drab | if the disks had stuff on it | 17:33 |
| nacc | while not having done this with raid, i've reinstalled many systems in the past that were already installed | 17:33 |
| nacc | drab: does it only happen with raid? | 17:34 |
| drab | even if they had a previous install, parted stops and asks me to confirm which device I wanna use and stuff | 17:34 |
| drab | nope, with a single disk too, same issue | 17:34 |
| nacc | drab: then you're not telling preseed enough | 17:34 |
| nacc | partman-lvm/device_remove_lvm boolean true | 17:34 |
| drab | I'm sure, I just can't figure out what I'm missing | 17:34 |
| nacc | partman-lvm/confirm boolean true | 17:34 |
| drab | lemme dpaste it | 17:34 |
| drab | http://dpaste.com/30B43FQ | 17:35 |
| drab | nacc: I have all of those already | 17:35 |
| drab | that's a grep partman srv1604.seed | 17:35 |
| nacc | drab: can you pastebin your whoel preseed? | 17:37 |
| nacc | drab: iirc, what you have is sufficient for everything to get wiped by the installer and if it's still prompting you for a selection, then something else is wrong | 17:38 |
| nacc | drab: and please be precise as to where it stops, becasuse "asks me to confirm wich device ... and stuff" doesn't help me undersatnd where the preseed is stopping | 17:40 |
| nacc | drab: ideally screenshots, i think | 17:40 |
| drab | nacc: ok, I'll get to that, gimme a few, thank you | 17:44 |
| drab | I should have a windows VM on vbox to repro this so that I can get actual sshots instead of blurry pics with my phone | 17:45 |
| nacc | drab: in the meawhile, can you pastebin your entire preseed? | 17:48 |
| drab | nacc: k, that I can certainly do right away, sec | 17:49 |
| drab | nacc: ok this has everything , line from pxelinux that I start the install with + srv1604.seed + the partman diff with the raid1 version | 17:58 |
| drab | http://dpaste.com/27KH6SP | 17:58 |
| drab | thank you for taking the time to look | 17:59 |
| nacc | drab: do you have multiple physical disks? | 18:03 |
| drab | nacc: in the server using the raid-1, yes, in the testbox using the simple one, no, just one ssd | 18:07 |
| nacc | drab: in the latter case, does it help to specify | 18:07 |
| nacc | d-i partman-auto/disk string /dev/sda | 18:07 |
| drab | ok, I'll add and try with that and see if it helps | 18:08 |
| drab | there is the equivalent of that in the raid1 already tho, and I still get errors due to raid being mounted, but that might be a diff issue | 18:09 |
| nacc | drab: right i think it is | 18:09 |
| nacc | drab: hence why i want to see where preseed stops :) | 18:09 |
| drab | ok | 18:09 |
| drab | I'm still working on getting a VM going, it's a bit of a multitasking morning with a few more interruptions than usual, appreciate your patience | 18:10 |
| nacc | drab: np, i might need to step away for a bit to run some errands/lunch | 18:10 |
| drab | no worries at all, thank you for your help | 18:11 |
| drab | btw I just figured out another neat trick this morning, just in case anybody cares... | 18:12 |
| drab | to do end-to-end ansible installs | 18:12 |
| drab | or anything else really, would be the same with chef, if you wanted to trigger a push and need ssh | 18:12 |
| drab | the late-command can install ssh in /target and then you can just start it and it'll work just fine so than you can ssh in/push stuff to it and make all the changes before rebooting | 18:13 |
| drab | plus put in the bios boot from hd first, second network, so now I can WOL machines at night, dd a few bits to the disk to remove the mbr, reboot, and it'll go into pxe, install and then ansible it | 18:14 |
| drab | poor man ipmi :) | 18:14 |
| rgb-one | Hey | 20:05 |
| rgb-one | any osTicket users here? | 20:05 |
| tarpman | oh wow. been years since I heard that name.. | 20:09 |
| tarpman | rgb-one: not any more, and boy am I grateful for that! | 20:09 |
| rgb-one | tarpman, hehe why do ya say that? | 20:10 |
| drab | tarpman: is there a better alternative? I've been looking for a simple ticketing system for ppl to report problems, but didn't find much | 20:24 |
| rgb-one | drab, I found a list on reddit | 20:37 |
| tarpman | drab: I moved to request tracker | 20:41 |
| drab | rgb-one: link? I saw a whole bunch, but they are all way too complicated or kinda broken | 20:42 |
| tarpman | rgb-one: embarrassing... it's long enough ago that I'm actually having trouble remembering specifics | 20:42 |
| rgb-one | some free ones, Request Tracker and OTRS | 20:44 |
| rgb-one | https://www.reddit.com/r/sysadmin/comments/na2r0/to_my_fellow_helpdesk_operators_what_trouble/ | 20:44 |
| rgb-one | Free ticketing systems: https://www.reddit.com/r/sysadmin/comments/2pp8op/free_ticketing_systems/ | 20:46 |
| drab | rgb-one: if you go through that list it basically seems to come down to the usual 2 tho, OTRS and RT | 20:51 |
| drab | everything else isn't free (despite the topic, see Jira) or is the usual hosted web thingie | 20:51 |
| rgb-one | do you use either of those? | 20:51 |
| drab | I have in the past | 20:51 |
| drab | and they are too complicated for where I'm at now | 20:52 |
| rgb-one | Oh | 20:52 |
| drab | I almost just need a form with a listing at the back | 20:52 |
| drab | a mini django site would do I reckon | 20:52 |
| drab | even just sending me an email would work... I could do that to start actually | 20:52 |
| drab | I almost implemented it as a google form... I just need a few questions/guided step for ppl to report problem | 20:53 |
| drab | so that they don't write "my internet is broken" | 20:53 |
| drab | and it turns out they were at home... not joking | 20:53 |
| drab | I don't need multi user, report generating ITIL TLA MSG BLAH BLAH super duper flashy mobile first | 20:54 |
| drab | :P | 20:54 |
| drab | but it seems I'm a minority so there's no such thing | 20:54 |
| rgb-one | I see | 21:05 |
| drab | nacc: this was my other problem btw, a bug still open since 2011... https://bugs.launchpad.net/ubuntu/+source/netcfg/+bug/713385 | 21:11 |
| ubottu | Launchpad bug 713385 in netcfg (Ubuntu) "netcfg/choose_interface=auto fails to find the right interface" [Medium,Confirmed] | 21:11 |
| drab | still working on those sshots | 21:11 |
| drab | I have the same prob as the initial guy, server with a quadport nic | 21:12 |
| nacc | drab: and they don't report link up even though they have link? | 21:13 |
| drab | the problem is with the "predictable" names, in some cases the "first" port is not the one I have pxe set up on | 21:17 |
| drab | I understand the theory about predictable naming, but honestly I never had an issue with eth* stuff coming out of order and I could reliably say to pick, say eth4 for pxe | 21:18 |
| nacc | drab: and do you pass BOOTIF= down? | 21:18 |
| drab | so I used ifnames=0 to go back to that, which worked and could reliably pxeboot stuff, but that broke everything when I started working with the new VM server and need to preconfigure bridges | 21:19 |
| drab | have not used BOOTIF=, but I passed netcfg/choose_interface=eth0 if it means the same thing | 21:19 |
| nacc | well, if you use BOOTIF= netcfg/choose_interface=auto should work | 21:20 |
| nacc | fi you don't use BOOTIF=, then yes, you might need to specify the network interface | 21:20 |
| nacc | drab: if you don't use your recipes (but use 'atomic' or something) does it work? | 22:14 |
| drab | nacc: I did some more tests... it works with auto, but it doesn't do what I'd like it to do. basically, for whatever reason, what by the rear panel are port 3 and 4 come up "earlier" with systemd and are named enp129XXXX Vs the other two enp4XXX | 22:15 |
| drab | so I guess they are selected first and stuff gets installed/set up with the wrong interface | 22:16 |
| nacc | strange | 22:16 |
| drab | the "funny" thing is, if I disable predict interafces with ifnames=0 | 22:17 |
| drab | then the enp4XXX gets eth0 etc | 22:17 |
| drab | so eth0-3 match the panel layout | 22:17 |
| drab | and I get preseeding etc on eth0 which is what I want | 22:17 |
| drab | but like I said if I do that then I get other problems when I get to setting up the bridge | 22:18 |
| drab | at this point I'm inclined to give up and work around it with ansible | 22:19 |
| drab | as long as the install works with predictable names, when the box comes back I can reconfigure it | 22:20 |
| drab | the thing that makes even less sense is that the dhcp server is set to tftp *only* on that first interface, the others don't | 22:21 |
| drab | so it pxeboot from iface1, then when installer stuff it loaded order is rearranged by systemd or whatever | 22:22 |
| drab | it dhcp out on iface3, gets an ip and continues the installation from there | 22:22 |
| drab | I guess a good fix would be to have the installer to use the same iface it pxebooted on, but it might not know what that is | 22:23 |
| drab | nacc: I'll test with atomic | 22:24 |
| drab | nacc: nope, same error, no root file system defined | 22:29 |

| drab | there's no raid on that disk, it's an old windows disk, or maybe windows was installed with fakeraid and that did something to it... | 22:59 |
| JMichaelX | did a release upgrade a few weeks ago on home server, from 14.04 to 16.04, and just noticed that installation is using kernel 3.13.0-110-generic | 23:08 |
| JMichaelX | desktop on 16.04 is using kernel 4.4.0-66-generic. is there a reason for this difference? | 23:09 |
| genii | You haven't done a dist-upgrade | 23:10 |
| drab | JMichaelX: 16.04 server uses 4.4.65 too, prolly just missing a dist-upgrade | 23:10 |
| sarnold | JMichaelX: how did you do the upgrade? | 23:13 |
