[00:24] I get the million <3 [00:24] 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" [00:25] 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] that seems to avoid the bridge device which wuoldn't match and therefore it all works in the end [00:26] mega workaround but worth a million. at some point that systemd bug will make it through and it'll "just work" [tm] [00:30] 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 === JanC is now known as Guest79577 === JanC_ is now known as JanC [00:39] OerHeks: that post itself says that method doesn't :) [00:39] anyway it's fixed per above [00:39] I'm gonna go enjoy the million dollar :P [00:40] certainly hard earned [00:42] oh [02:07] Do we have a stable kernel release that works with AM4 ? [02:07] Reading the release notes it looked like 4.10 was promising but i wanted some opinions [02:08] DirtyCajun: I suspect most folks just use xeons. You may have better luck in #ubuntu [02:10] That is the pleb channel. i stay far away [02:11] hehe [02:11] Xd [02:11] I dunno why you don't ask in the kernel channel [02:11] I just figured it'd be more likely a gamer would know.. [02:11] Wat. its not for gaming [02:11] its a 16 thread proc. its for my plex 2u [02:11] heh? not for gaming? [02:11] oh? I thought this was the new amd cpu; the only other person who's mentioned it on irc is a gamer.. [02:11] dunno what an AM4 even is [02:12] people use amd in servers? [02:12] absolutely [02:12] never seen one, ever [02:12] wel.... i work at a datacenter [02:12] and it is in about 40% of our blades [02:13] I have racks of servers, not a single amd [02:13] well what do you know, an amd chip in a server ;) http://www.thinkmate.com/system/stx-nl-qe12-2210 [02:13] :) [02:13] they are always horrible for my performance workload, due to the lack of ondie l2 cache that intel has [02:13] patdk-lap, check out the specs of the Ryzen [02:13] and the upcoming server grade chips [02:14] ya, I'll wait for real benchmarks [02:14] why is mdadm and preseeding such a pain to work with :( [02:14] as the benchmarks so far, are not accurate [02:14] passmark has 50+ [02:14] in fairness it's insanely hard to do benchmarking well [02:15] 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] due to having double the amount of memory channels [02:15] ya, anyone can make something beat the crap out of something else in one area, I want to know about normal workloads :) [02:17] gah [02:17] 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] I guess for a in memory database, that might be ok, if the ondie cache is acceptable to actually run the sql server [02:18] hehe [02:18] I'll wait a year or two atleast [02:19] 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] intel has pretty much deadended their cpu lines though [02:19] have I missed it? [02:19] 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] 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 [02:26] 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] seems light [02:28] man, have to go all the way down to a e5-2620v4 to find an 8core intel [02:28] 20mb cache [02:29] not as bad as it used to be [02:29] 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] 4 memory channels [02:30] so says ark, hehe :) [02:30] so says my m otherboard :) [02:30] so it *might* be comparable [02:31] have to see what pricing turns out to be [02:31] cpubenchmark said it'd be a bit cheaper than my cpu [02:31] if you had compute-bound tasks rather than memory bound tasks, the ryzen might be a good fit [02:32] ya, most workloads are memory issues [02:32] except stuff like encoding video [02:32] I don't know why that isn't memory bound, as I would think it should be :) [02:33] it's nice to know amd's in the game again [02:33] intel did take themselves out of it [02:33] been years since they made progress [02:33] and now they basically admitted to giving up [02:33] they haven't had any real need [02:33] sure they have [02:34] they have almost let arm overrun them [02:34] back in early opteron days [02:34] but it's been a decade [02:34] intel is getting backed into a server cpu corner [02:34] with this, more and more amd systems for desktops, maybe laptops [02:35] but more and more laptops are going arm by being replaced with tablets and phones and stuff [03:41] how to duplicate a server using the same configuration ? === lordievader is now known as Guest76127 === Guest76127 is now known as lordievader [07:55] 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 [07:56] there are no dropped packets. no denies on the firewall [07:56] i dont find anything at all [07:56] just that its incredible slow [07:57] all 3 vlans are using the same physical connection [07:58] the VM that runs vlan 501 has no memory or cpu problems [07:59] they all run 16.04 latest patches [08:42] i found the problem [08:43] fyi there was proxy arp enabled on the firewall for vlan 501 [08:44] i found that in tcpdump there were no arp requests [11:42] 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. [11:46] a8o: first hit on google is http://askubuntu.com/questions/67283/is-it-possible-to-make-writing-to-bash-history-immediate [11:47] if you keep dropping your connection you may want to consider using mosh [11:47] cool thanks. [11:47] I use mosh on some systems, but not all can have it. [11:57] a8o: true enough [12:01] 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] never heard of tmux. [12:02] 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. [12:03] 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). [12:04] 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. [12:05] if anything it's fun to try something new. Lately I've been using the fish shell. Love that one [15:22] coreycb: hello [15:22] coreycb: https://launchpadlibrarian.net/311293238/buildlog_ubuntu-zesty-amd64.vmware-nsx_10.0.1~git20170317.bfa48c0-0ubuntu1~ubuntu17.04.1~ppa201703171404_BUILDING.txt.gz [15:22] does that seem familiar to you - I can't get vmware-nsx to build in a PPA [15:22] coreycb: builds fine locally/on a cloud instance using sbuild [15:24] jamespage, haven't seen that before. i wonder if the tests do any db setup that is getting missed for some reason. [15:30] jamespage, i see run_tests.sh has an option to recreate the database [15:30] coreycb: yeah not sure about that [15:31] coreycb: afaict nothing ever gets re-created on disk [15:31] created rather [15:31] coreycb: I lied as well - it failed on my laptop [15:31] jamespage, oh.. [15:37] anybody here using ansible by any change and has it working with a preseeded install against the in-target chroot? [15:59] coreycb: hmm [15:59] coreycb: I might have it identified [15:59] coreycb: why do we have a patch to make unit tests use an on-disk sqlite db? [16:00] jamespage, is that in vmware-nsx? [16:00] coreycb: no in neutron [16:00] coreycb: disabling it to see if that helps [16:01] jamespage, ok, not sure i'll take a look at it though [16:36] can ubuntu core be used on an intel pc with 4 Etherports as an gateway/rooter … firewall [16:49] station: I'm doing that [16:49] actually just getting through the bonding part on a second machine to get a "4gbit" link [16:50] oh nm, you said core, assumed -server since this is -server, nm [16:53] drab: what did you use to set it up? is it a bad idea to alsow host like security cam directly on the rooter? [16:54] im new to server .... [16:55] 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 [16:59] drab: so i could set open sense / pfsense on one "roooter PC" and a separate server [17:01] [17:01] station: what are you trying to achieve? I'm having troubles to understand what you're asking for [17:02] are you trying to build a firewall for your home? [17:05] 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 … [17:09] was hoping to get them both on one device with ubuntu core but … [17:20] 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] but I don't see any other place/ML where -server ppl are hanging out to ask a question [17:25] drab: you can ask here [17:26] drab: you can ask on -server too, you might just get redirected around a bit; i wonder if ubuntu-users is the right place [17:30] nacc: I doubt -users deal a lot with preseed, feels like asking in ubuntu-desktop :P [17:30] but maybe I'm wrong, not on -users [17:30] drab: what's your question? [17:31] 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] I have two preseed problems [17:31] both on -server and -desktop actually, altho latetr may be a bug in ubiquity installer [17:31] so on -server, I can't figure out how to get preseed to ignore everything on the drive [17:32] if I try to re-pxe a sytem that had raid on it, initrd I think will autostart the md device [17:32] by the time parted kicks in the drives are in use and everything fails because there's no root device [17:32] pxe doesn't depend on a physical device being present for root [17:33] I have to manually get a shell, mdmad --zero-superblock, stop the mdadm device, and then dd zeros for good measure [17:33] sure, talking about preseed [17:33] I can't basically reinstall a system automatically as it stands [17:33] if the disks had stuff on it [17:33] while not having done this with raid, i've reinstalled many systems in the past that were already installed [17:34] drab: does it only happen with raid? [17:34] even if they had a previous install, parted stops and asks me to confirm which device I wanna use and stuff [17:34] nope, with a single disk too, same issue [17:34] drab: then you're not telling preseed enough [17:34] partman-lvm/device_remove_lvm boolean true [17:34] I'm sure, I just can't figure out what I'm missing [17:34] partman-lvm/confirm boolean true [17:34] lemme dpaste it [17:35] http://dpaste.com/30B43FQ [17:35] nacc: I have all of those already [17:35] that's a grep partman srv1604.seed [17:37] drab: can you pastebin your whoel preseed? [17:38] 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 [17:40] 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] drab: ideally screenshots, i think [17:44] nacc: ok, I'll get to that, gimme a few, thank you [17:45] 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 [17:48] drab: in the meawhile, can you pastebin your entire preseed? [17:49] nacc: k, that I can certainly do right away, sec [17:58] 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] http://dpaste.com/27KH6SP [17:59] thank you for taking the time to look [18:03] drab: do you have multiple physical disks? [18:07] nacc: in the server using the raid-1, yes, in the testbox using the simple one, no, just one ssd [18:07] drab: in the latter case, does it help to specify [18:07] d-i partman-auto/disk string /dev/sda [18:08] ok, I'll add and try with that and see if it helps [18:09] 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] drab: right i think it is [18:09] drab: hence why i want to see where preseed stops :) [18:09] ok [18:10] 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] drab: np, i might need to step away for a bit to run some errands/lunch [18:11] no worries at all, thank you for your help [18:12] btw I just figured out another neat trick this morning, just in case anybody cares... [18:12] to do end-to-end ansible installs [18:12] or anything else really, would be the same with chef, if you wanted to trigger a push and need ssh [18:13] 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 [18:14] 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] poor man ipmi :) [20:05] Hey [20:05] any osTicket users here? [20:09] oh wow. been years since I heard that name.. [20:09] rgb-one: not any more, and boy am I grateful for that! [20:10] tarpman, hehe why do ya say that? [20:24] 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 [20:37] drab, I found a list on reddit [20:41] drab: I moved to request tracker [20:42] rgb-one: link? I saw a whole bunch, but they are all way too complicated or kinda broken [20:42] rgb-one: embarrassing... it's long enough ago that I'm actually having trouble remembering specifics [20:44] some free ones, Request Tracker and OTRS [20:44] https://www.reddit.com/r/sysadmin/comments/na2r0/to_my_fellow_helpdesk_operators_what_trouble/ [20:46] Free ticketing systems: https://www.reddit.com/r/sysadmin/comments/2pp8op/free_ticketing_systems/ [20:51] rgb-one: if you go through that list it basically seems to come down to the usual 2 tho, OTRS and RT [20:51] everything else isn't free (despite the topic, see Jira) or is the usual hosted web thingie [20:51] do you use either of those? [20:51] I have in the past [20:52] and they are too complicated for where I'm at now [20:52] Oh [20:52] I almost just need a form with a listing at the back [20:52] a mini django site would do I reckon [20:52] even just sending me an email would work... I could do that to start actually [20:53] I almost implemented it as a google form... I just need a few questions/guided step for ppl to report problem [20:53] so that they don't write "my internet is broken" [20:53] and it turns out they were at home... not joking [20:54] I don't need multi user, report generating ITIL TLA MSG BLAH BLAH super duper flashy mobile first [20:54] :P [20:54] but it seems I'm a minority so there's no such thing [21:05] I see [21:11] nacc: this was my other problem btw, a bug still open since 2011... https://bugs.launchpad.net/ubuntu/+source/netcfg/+bug/713385 [21:11] Launchpad bug 713385 in netcfg (Ubuntu) "netcfg/choose_interface=auto fails to find the right interface" [Medium,Confirmed] [21:11] still working on those sshots [21:12] I have the same prob as the initial guy, server with a quadport nic [21:13] drab: and they don't report link up even though they have link? [21:17] the problem is with the "predictable" names, in some cases the "first" port is not the one I have pxe set up on [21:18] 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] drab: and do you pass BOOTIF= down? [21:19] 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] have not used BOOTIF=, but I passed netcfg/choose_interface=eth0 if it means the same thing [21:20] well, if you use BOOTIF= netcfg/choose_interface=auto should work [21:20] fi you don't use BOOTIF=, then yes, you might need to specify the network interface [22:14] drab: if you don't use your recipes (but use 'atomic' or something) does it work? [22:15] 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 [22:16] so I guess they are selected first and stuff gets installed/set up with the wrong interface [22:16] strange [22:17] the "funny" thing is, if I disable predict interafces with ifnames=0 [22:17] then the enp4XXX gets eth0 etc [22:17] so eth0-3 match the panel layout [22:17] and I get preseeding etc on eth0 which is what I want [22:18] but like I said if I do that then I get other problems when I get to setting up the bridge [22:19] at this point I'm inclined to give up and work around it with ansible [22:20] as long as the install works with predictable names, when the box comes back I can reconfigure it [22:21] 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 [22:22] so it pxeboot from iface1, then when installer stuff it loaded order is rearranged by systemd or whatever [22:22] it dhcp out on iface3, gets an ip and continues the installation from there [22:23] 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 [22:24] nacc: I'll test with atomic [22:29] nacc: nope, same error, no root file system defined [22:31] hello all, recently setup server 16.04 and I have an issue where after a reboot, I have to complete a local login before SSH with key login will work [22:32] ran systemctl enable ssh and still same issue [22:39] anybody around === notdaniel is now known as notdaniel_ [22:58] ok so I found the error... [22:59] nacc: ubiquity: error ddf1 wrong # of devices in RAID set "ddf1_kvm5" on /dev/sda [22:59] I've no idea why I get that [22:59] 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... [23:08] 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 [23:09] desktop on 16.04 is using kernel 4.4.0-66-generic. is there a reason for this difference? [23:10] You haven't done a dist-upgrade [23:10] JMichaelX: 16.04 server uses 4.4.65 too, prolly just missing a dist-upgrade [23:13] JMichaelX: how did you do the upgrade?
