[00:26] or a missing dep ? [00:27] also, my /etc/lxc directory is empty [00:27] (I have no basic.conf) [00:27] SpamapS: ^ [00:29] hm [00:30] lifeless: /etc/lxc is in fact intentional [00:30] lifeless: but I think cgroup-bin seems like it should be in lxc's Depends or at least Recommends [00:31] as its not much use w/o cgroups [00:35] SpamapS: so, can I have your basic.conf ?

[00:40] hallyn: if you're around.. lifeless is working with LXC and curious why it doesn't recommend/depend on cgroup-bin (I am also curious about that) [00:41] lifeless: I believe hallyn is EDT or CDT US, so he may be past EOD today [00:41] bug 800456 [00:41] Launchpad bug 800456 in lxc "no dependency on cgroup-bin" [Undecided,New] https://launchpad.net/bugs/800456 [00:41] new baby at home tho so there's no telling when he's sleeping or awake. :) [00:41] * SpamapS confirms that [00:42] lifeless: note that it may be related to bug 784093 [00:42] Launchpad bug 784093 in lxc "lxc broken by cgroup-bin" [High,Confirmed] https://launchpad.net/bugs/784093 [00:42] sure [00:42] I posted a workaround for that bug which I'm using now [00:44] https://dev.launchpad.net/Running/LXC#preview is what I'm building up === medberry is now known as med_out [00:47] Daviey can look at the by end of week [00:47] SpamapS: how do you tell lxc-create to use the local proxy ? [00:52] I cannot access my printer on ubuntu server 10.04 from other computers (windows) on network. How can I fix this? HP printer with CUPS [00:54] lifeless: it runs debootstrap, which respects the appropriate environment variables I think. If they're being stripped, add them to /etc/default/lxc [00:55] it was sudo [00:55] lifeless: I use MIRROR=http://127.0.0.1:9999/ubuntu in mine.. which is the path to my local approx cache [00:55] sudo http_proxy=... lxc-create...

[01:27] ...done. [01:27] after i try to restart networking using the sudo /etc/init.d/networking restart [01:27] ntoombs: thats not actually a valid way to "restart networking" [01:28] i have my network set up on static using the device eth1 [01:28] what is a valid way then? [01:28] i've done it before using dhcp [01:28] but static messed it up [01:28] For static it *should* work... [01:29] right but for some reason it's not [01:29] ntoombs: all that does is ifdown -a and ifup -a [01:29] i've been into my /etc/network/interfaces file and made sure everything is "correct" as far as i know [01:29] ntoombs: can you do 'ifdown eth1 ; ifup eth1' ? [01:29] i have before and i've gotten errors [01:29] i will post them [01:29] one sec [01:30] sudo ifdown eth1 [01:30] ifdown: interface eth1 not configured [01:30] sudo ifup eth1 [01:31] SIOCADDRT: No such process [01:31] Failed to bring up eth1 [01:31] first check that eth1 exists in 'ifconfig -a' [01:31] i've looked in about every ubuntu and linux server forum there is out there and i still havn't fixed it [01:32] those errors are usually hardware/driver level [01:32] i know it's there [01:32] i put it there [01:32] yes, but does it show up in ifconfig -a? [01:32] :( don't tell me that [01:32] configuring it and it showing up are different things [01:32] yes it does [01:32] ok [01:32] does setting it manually with ifconfig work? [01:33] sudo ifconfig eth1 1.2.3.4/24 up [01:33] i've tried that too but i'll try again [01:34] if it does work, it's likely an issue with the configuration or ifup [01:34] if it doesn't work, try this first [01:34] i use the internal ip right? [01:34] sudo ifconfig eth1 0.0.0.0 down [01:34] sudo ifconfig eth1 0.0.0.0 up [01:34] then configuring it with the IP you want [01:36] on doing the ifconfig eth1 1.2.3.4/24 up i got a right bracket pointing to my cursur [01:36] that's a syntax error [01:37] check that you didn't put in any \ or " or ' [01:37] press ctrl+c to escape [01:37] yea i did it wrong [01:37] lifeless: do you need cgroups-bin for some other reason, or was that just how you were getting cgroups mounted? [01:37] k this time no result [01:37] just a new line [01:38] that means successful [01:38] now 'ifconfig eth1' to verify [01:38] lifeless: assuming this is on natty or oneiric, can you try without cgroups-bin, and just with fstab mounting cgroups? [01:38] I suspect that'll allow lxc-stop to work [01:38] yea it's 11.04 natty narwhal [01:39] ifconfig eth1 gave me what it gave me before [01:39] hallyn: just following SpamapS instructions :) [01:39] if it shows the address you set, it worked and there's nothing wrong with your interface [01:39] and the problem is either with your /etc/network/interfaces or something in ifup [01:40] well when i had my interface setup up on dhcp [01:40] if it shows a different or no address, you probably have something else hooking it [01:40] like dhcpcd [01:40] i could ping anything all day long [01:40] it showed the ip address that i set to it staticaly [01:40] so the interface is fine [01:41] next most likely is an error in /etc/network/interfaces, pastebin it if you can [01:41] yea and the netmask is 255.255.255.0 [01:41] ok one sec [01:41] i'll block out the ip [01:41] don't [01:41] ok [01:41] showing your IP isn't a security risk, everyone in here is publicly showing theirs [01:42] by connecting to freenode at all, you are [01:42] plus, if it's behind a NAT, it's meaningless to anyone but you anyway [01:42] http://pastebin.com/VhyRDawJ [01:42] k [01:43] i'm a networking noob [01:43] thank you so much for helping me :) [01:43] looks fine [01:43] try this [01:43] i can access my router with that gateway in my browser [01:43] sudo ifconfig eth1 0.0.0.0 up; sudo ifup eth1 [01:44] same error i've been getting [01:44] SIOCADDRT: No such process [01:44] Failed to bring up eth1. [01:45] lifeless: ok, cool, then just don't use it :) [01:45] I just have [01:45] cgroup /sys/fs/cgroup cgroup defaults 0 0 [01:46] i don't understand hallyn [01:46] (in fstab) [01:46] ntoombs: sorry wasn't directed at you [01:46] oh sorry [01:46] i guess i'm missing the other side of the conversation [01:47] ntoombs: just having a very async conversation with lifeless :) [01:47] ntoombs, try changing in your /etc/network/interfaces file [01:47] so that 'address 1.2.3.4' is just like that, with only one space [01:47] on all the lines [01:47] ok [01:48] done [01:48] and try ifup again [01:49] same error [01:49] sudo ifconfig eth1 192.168.254.115 up; sudo ifup eth1 right? [01:49] just sudo ifup eth1 [01:50] yea same error [01:51] well [01:51] unless your interfaces file is somehow different [01:51] the networking restart thing worked with dhcp [01:51] it doesn't work with static [01:52] does that count as different? [01:52] paste/pastebin the result of 'sudo route -n' [01:52] that error message means that it can't add a route because it's outside the valid range [01:53] How do I share a cups printer? [01:53] http://pastebin.com/i4qcmrzu [01:53] the 192.168.254.115 was assigned by dhcp [01:53] i didn't change it [01:54] route doesn't seem to recongnise my default gateway [01:54] it isn't set [01:54] without -n it just shows an asterix [01:54] try this [01:55] http://pastebin.com/index/VhyRDawJ [01:55] change your /etc/network/interfaces to that, and reboot [01:56] assuming .15 is not already in use [01:56] you can use another one if it is, just choose one outside the DHCP range [01:56] which is probably 100-200 [01:57] nothing is different [01:57] and i'm working on a headless server from an ssh connection from my mac so if i reboot i'm afraid i won't be able to get back [01:57] i'll check the range [01:58] well, you can't very well change network settings without disconnecting [01:58] are you connected to a different interface? [01:58] it's from 1 - 253 :P [01:58] well, you should limit that [01:58] you can if you use networking restart [01:58] and then choose an address outside of it [01:59] using 'networking restart' would, in fact, disconnect you if the settings changed [01:59] if you did not get disconnected, it means the settings didn't change [01:59] yea it did last time [01:59] and i had to reconnect [01:59] i guess i just got lucky [01:59] ok i'll reboot [01:59] your pastebin file... what was different? [02:00] I just added network and broadcast [02:00] and removed the extra spaces [02:00] oh i had that earlier [02:00] but i didn't reboot [02:00] i'll try it [02:00] what is most likely, is something is hooking your interface and preventing the change from being made [02:00] a reboot would solve that issue [02:00] i don't see the network and broadcast in there [02:01] its network 192.168.254.0 [02:01] ff [02:01] and broadcast 192.168.254.254? [02:01] http://pastebin.com/muYERLhT [02:01] sorry [02:01] no problem :) [02:02] and should i change the dhcp range in my router? [02:02] yes [02:02] if the router tries to hand out the IP you're using, it'll be troublesome [02:02] k i'm doing all that right now [02:02] brb [02:02] so you should open a gap in that DHCP range, and use it for your statics [02:03] Or simply instruct the DHCP server to statically allocate leases by MAC for specific IPs [02:04] should i unplug my router for changes to take effect? [02:04] no [02:04] ok [02:04] unless your router is a really poor quality one [02:04] lol [02:04] it should apply once you click save [02:04] it's not that bad [02:04] it's applied but my desktop isn't assigned a local ip anymore [02:05] i'm on my laptop [02:05] but it's no problem for now [02:05] hallyn: sorry, was on the phone for a bit there [02:05] i'll edit my interfaces file now [02:05] hallyn: I'd rather not be telling folk to mount cgroups by hand in my docs - https://dev.launchpad.net/Running/LXC#preview [02:05] lifeless: not even using fstab? [02:05] hallyn: particularly as folk may have cgroup-bin installed for other reasons [02:06] which would presumably clash in fun ways [02:06] not-quite-sleeping baby in lap, would you midn talking tomorrow? [02:06] rebooting now [02:06] lifeless: i think the real problem with the cgroups is that lxc-init doesn't start in cgroup:/ like it expects. (Since you seem to have all cgrousp compsited under same dir, that's the only thing that should be going wrong) [02:07] lifeless: if this is high priority, i can take a crack at solving this tomorrow [02:07] should be about a day's work, and like i say, it needs to be done sometime [02:08] hallyn: well, I have a workaround (the new cgconfig from SpamapS) for folk using natty, which most lp devs are atm [02:08] qman__ looks like it's gonna time out and it's still not showing up on my router [02:08] only a few are brave enough to be on oni yet [02:09] hallyn: if we can get it sorted for oni release, that would be awesome [02:09] ntoombs, it's not getting a DHCP lease, so it won't show up in the router [02:09] try pinging the IP address you gave it [02:09] lifeless: so it all works with SpamapS' config? [02:09] hallyn: well, it doesn't shutdown on lxc-stop [02:09] hallyn: but poweroff inside it appears to work [02:09] qman__: it would ping once then timeout [02:10] lifeless: ok, cool, if you can get work done with that, that's great [02:10] we certainly can; I like to report all friction I run into though. [02:10] ntoombs, does it keep doing so? [02:10] qman__: dont i need it to show up on the router to do port forwarding and connect to the internet? [02:10] hallyn: I'll file a separate bug about the lxc-stop not working [02:10] lifeless: cool, i'll put cgroup-bin interaction high on todo list meanwhile [02:11] as in, one response per ping? [02:11] lifeless: ok, thanks [02:11] hallyn: sweet, thanks [02:11] qman__: yes it times out every time after the first packet [02:11] hallyn: one thing that would be -awesome- [02:11] hallyn: would be a template that bind mounts /home and uses the same uids [02:11] so if you stop and start a new ping, the first packet gets a response, but none after that? [02:11] qman__: i get one good packet then it times out every second after [02:11] qman__: correct [02:12] that's either a hardware problem, a driver problem, or a really bizarre firewall problem [02:12] lifeless: shouldn't be too bad. would you want just /etc/shadow entries for uids 1000+ copied over, or the whole thing? [02:12] hallyn: let me describe my use case; then you can decide :) [02:13] physically, how are you connected? [02:13] direct to the router, or through a secondary switch? [02:13] hallyn: I want to do LP development in a lxc container rather than a VM [02:13] lifeless: the thing i've been using a lot (from ppa) is lxc cloning with LVM. Seems like something which could be good for lp dev [02:13] qman__: well the server is connected by ethernet direct to the router. and i connect via ssh from a terminal on my mac [02:13] hallyn: so in the container I want to install rabbitmq, postgresql, apache etc [02:13] hallyn: and I want my source code sitting in my /home/robertc [02:13] mac is over ethernet or wifi? [02:14] hallyn: where I can edit it as normal, commit with my bzr & gpg keys etc [02:14] How do I access a shared printer from Windows? [02:14] wifi [02:14] i can do eathernet though [02:14] try plugging into ethernet, and trying [02:14] it might be a wifi thing on the router [02:14] hallyn: then run the tests within the lxc container, using the lxc postgresql, rabbit apache [02:14] ok [02:14] and again thanks a ton for helping :) [02:14] most people would have given up by now [02:15] this might disconnect me [02:15] not a problem, some routers do some strange things in the name of 'security' [02:15] hallyn: so inside the lxc it needs to write to me homedir without messing stuff up, but I don't care about service accounts [02:15] lifeless: would you want the whole /home bind-mounted? just ~/src or something? [02:16] hallyn: whole home/$me would be easiest to reason about I think [02:16] 'without messing stuff up' meaning not changing owner uids, right? [02:16] yeah [02:16] ok [02:16] oh for bonus points, [02:16] lifeless: i think i'd use that myself :) would that be higher prio for you than cgroup-bin? [02:16] definitely [02:17] hallyn: bug 798476 is also a very interesting one for me [02:17] Launchpad bug 798476 in lxc "it would be really useful to be able to make i386 lxc containers on a amd64 machine" [Undecided,New] https://launchpad.net/bugs/798476 [02:17] hallyn: LP memory use is much lower on i386 [02:17] qman__: my router says i'm still connected wirelessly and my ping comes back the same. i have airport turned off co i can't connect to anything wirelessly [02:17] hallyn: shall I file a bug about the developer bind-mounting template [option, whatever - i dunno how it all hangs together yet] [02:18] lifeless: sure, that's good. (not sure hwo kosher it is to just add things to the blueprint right now) [02:18] well, I don't know anything about macs, but you didn't even time out, so you'd have to have the same IP address [02:18] which is unlikely if you switched to wired [02:18] lifeless: hm, people *have* run i386 containers on amd64 [02:19] but i can't remember who [02:19] yeah [02:19] qman__: i really think i just have a dumb router [02:19] its probably just a case of passing the arch flag to debootstrap [02:19] hallyn: I do it [02:19] ntoombs, entirely possible [02:19] it *should* be trivial [02:19] Actually, I did it only to see if I could; I don't in productioin [02:19] twb: is it more than ^ [02:19] http://paste.debian.net/120603/ [02:20] Look in there for references to $arch [02:20] if you think that's the case, I'd give the router a reboot then [02:20] twb: thanks [02:20] sounds good [02:20] brb [02:20] Looks like only issue is debootstrap [02:20] And as a knock-on effect, which debootstrap cache I copy [02:22] twb: nifty, thanks [02:24] hallyn: bug 800482 [02:24] Launchpad bug 800482 in lxc "a home/$me bind-mounted template would rock" [Undecided,New] https://launchpad.net/bugs/800482 [02:24] Would it? [02:24] it would [02:25] qman__: i'm back [02:25] any luck? [02:25] qman__: now i'm getting errors like ping: sendto: host is down [02:25] and ping: sendto: no route to host [02:26] but now my router says i'm on ethernet :) [02:26] lifeless: cool, thanks [02:27] I'd try restarting the server again now that the router has rebooted, if you can reach the power button, just press it once quickly and it should power down [02:27] then press again to boot up [02:27] otherwise, if you can plug in a keyboard and press ctrl alt del [02:27] ok [02:27] How does one access a shared printer (CUPS) hosted on ubuntu 10.04 from Windows client? [02:28] quick press of a button did not a powerdown make [02:28] i could hold it but i'm assuming that is not advisable? [02:28] generally no [02:28] but if you're not running any software yet it shouldn't cause too much trouble [02:28] what filesystem are you using? [02:28] ext4 journaled so it's good [02:29] yeah [02:29] Just did an apt-get update && apt-get upgrade and it wants to upgrade language-pack-en which now suddenly has LOTS of crazy dependencies, including firefox and many X libs... anyone noticed this? I'm using v11.04 [02:29] to change anything i have to swap the hard drive to my desktop [02:29] but we're just doing a reboot right? [02:29]
