[00:17] wtfplymouth: I had some trouble with fstab when upgrading from dapper to hardy. can you be more specific with your problems? you haven't provided enough info for a response [00:18] hello to all. can somebody tell me how can i clean up my swap space ? i have php scripts that need a lot of memory and becouse of that the swap space is used a lot. the strange thing however is that my swap space is not cleaned up after the sripts finish. what can i do ? after a while i run out of swap space and my server freeze ! [00:19] hmmmm [00:19] first of all, it is usually other processes sitting in swap [00:19] so you have to get them to try to run and touch those pages [00:19] setting swappiness to 0 might help too [00:19] :) [00:22] domas: thanks :-) i have only 128 MB Ram and my scripts use both 160 MB. becouse of that the swap is used a lot but from my understanding the swap space should be given free after the script finish and exactly this is not the case [00:24] cclausen: i know that my fstab has a problem, but 9.10 booted with a not available disk and 10.04 stops the boot [00:25] i just want 10.04 to not stop the boot at an mounting error [00:25] wtfplymouth: you should be able append a root= line from grub [00:25] did you read the release notes? [00:25] there is something about specific hardware and a 1 MB disk alignment or something [00:26] not sure if that is related, but it might be worth a try [00:34] just installed ubuntu server 10.4, and i cant install openssh or openssh-client, or openssh-server [00:34] what's going on??? [00:35] is there a network connection at all? [00:35] what errors do you receive? [00:35] cclausen, talking to me? [00:35] yes [00:36] i've installed apache... installing mysql now... [00:36] and openssh-server is not working... [00:36] not installing [00:36] what command are you running? [00:36] and you say mysql is installing now. are you trying to run multiple installs at once? [00:36] sudo apt-get install openssh-server [00:36] no... [00:37] what error does apt-get give you? [00:37] let me finish installing mysql i'll tell you whats going on [00:37] thanks for the help [00:37] just a sec [00:41] cclausen, it says that it has a newer version [00:41] apt-get update; apt-get install --reinstall openssh-server [00:41] what EXACT error message? [00:42] cclausen, installing now with the --reinstall [00:42] :) [00:43] well then, no problem [00:43] you probably want to apt-get upgrade too and see if anything else has newer versions [00:45] what's the difference between upgrade and update? [00:47] update pulls in the list of newer packages [00:47] upgrade actually installs them [00:47] I think peopel are encouraged to use aptitude instead of apt-get these days [00:48] but I am not sure [00:48] aptitude safe-upgrade is probably what you want for patching most of the time, I think (feel free to correct me) [00:48] you can add the -u option to list what upgrades you have. [00:48] cclausen: that's the one [00:48] cclausen, got it [00:49] speaking of that, I've been trying to use the automatic upgrades [00:49] and I use aptitude now instead of apt-get... just out of laziness. I'd rather have one command instead of two (apt-get and apt-cache) for package management [00:49] but they don't see to automatically install [00:49] were the betas just not auto-updating b/c it was beta? [00:50] whaley: that sounds nice. I've been tired of two commands. [00:50] cclausen: you mean unattended-upgrades? [00:50] I think so [00:51] whatever the automatica updates from teh ubuntu server installer does [00:51] I was using cron-apt before [00:51] There's a whole ubuntu.org page I haven't read on that. [00:51] yeah, I think I read that and set the various config files to actually update [00:51] but whenever Ilog I see that there are updates waiting for me [00:51] I guess I'll what happens how that things are released [01:00] meh, why oh why is linux swapping, when it has few gigs of memory free [01:00] :) [01:00] if you don't think you need it, just swap -a off [01:00] swappiness is at 0 already [01:00] err, swapoff -a [01:01] well, kswapd gets stressed when only few gigs of memory available are left [01:01] it was spinning at 100% on one core [01:05] like here, http://p.defau.lt/?__SOOu0go_iFe9cWMCF29A [01:06] swappiness at 0, 1G of cache, 200M of free memory [01:06] wtfplymouth: the other option is to add 'nobootwait' as a boot option (see e.g. bug 510415). [01:06] Launchpad bug 510415 in ubuntu-release-notes "Lucid mountall can cause unexpected hangs" [Undecided,Invalid] https://launchpad.net/bugs/510415 [01:09] when will the docs for 10.4 server be online? i can't see it here: http://www.ubuntu.com/products/whatisubuntu/serveredition/techspecs/whatsnew [01:10] /etc/apache2/sites-enabled/000-default is empty what should i do? [01:10] that should be a symlink to sites-available [01:11] or are both empty ? [01:13] cclausen, i have to edit 000-default, to change the port... and i don't know why is empty [01:14] jaypur: is this a new install? You can remove the files and apt-get install --reinstall the various apache2 packages [01:14] should setup a new default for you [01:16] hmm i'll do this [01:16] to updgrade my server, should i change karmic to lucid in sources and run dist-upgrade? [01:16] just installed [01:16] owen1: http://www.ubuntu.com/getubuntu/upgrading [01:17] cclausen: thanks [01:17] also, are there docs about 10.4? [01:17] 000-default still empty [01:18] sudo nano /etc/apache2/sites-enable/000-enable [01:18] owen1: what specifically did you need docs on? [01:18] most of the on-system docs should be up to date for the packages installed, look in /usr/share/doc [01:18] as well as man pages [01:19] jaypur: I don't know what to tell you. are you sure you reinstalled the package that had the file you wanted in it? [01:19] hey i just set up a mailserver on a ubuntu box, i have postfix and dovecot with postgrey configured, what is the best way to include spamasassin? smapd oder amavis? [01:19] jaypur: apache2.2-common package was reinstalled? [01:20] i'm rebooting the pc just a sec [01:20] cclausen: i thought there is some kind of docs about running/maintaining/backups/system admin for ubuntu server. [01:21] jaypur: that nano command was wrong FYI. its not 000-enable (at least not to my knowledge) [01:21] owen1: those types of docs won't be too mcuh of a change from current versions. I'd just read what is out there now [01:21] cclausen, what should be the command [01:21] ? [01:22] jaypur: well, first, try ls -l /etc/apache2/sites-available [01:22] what files are there? a default file? [01:23] owen1: I use a daily rsync snapshot hardlink script for backups myself to conserve disk space on unchanged files [01:23] default, and default-ssl [01:24] cclausen: thanks for this insight. i found this page, i believe that is what you are refering to - https://help.ubuntu.com/community/Servers [01:24] got it [01:24] !!! [01:24] now it's on! [01:24] jaypur: sudo nano /etc/apache2/sites-available/default does that work? or is it empty too? [01:24] :) [01:24] now it's on [01:24] jaypur: I didn't think there was a problem. good [01:25] owen1: basically, that, yes [01:25] cclausen: i use rsync as well. what does it mean hardlink? [01:25] i know what symlink is. [01:25] cclausen, now i'll check the port [01:25] owen1: a hardlink is a directory entry that points to a file already on disk [01:25] http://tuxserver.no-ip.org/ [01:25] :) [01:26] owen1: read the docs on the --link-dest option to rsync [01:26] cclausen: great. thanks [01:27] owen1: there is an option to cp to copy using hardlinks as well. I sued this to create the initial directory to link-dest against. [01:27] owen1: and of course remember that you really want an off-site backup too, not just a local version [01:28] cclausen: right now i rsync to external usb drive [01:29] owen1: ah, ok, that works too. I have actual TSM backups for production servers do just do the rsync for my users to get data without needing to ask me to pull it down from TSM. [01:30] zorzar: I'd look for a guide online and try following the instructions. I haven't used postfix, but I had spamassassin working with exim4 on Debian sarge back in the day [01:31] cclausen: what made switch from debian server to ubuntu? [01:31] i am also curious about the differences between the two. [01:32] owen1: ubuntu has a stable release cycle and 5 year support on LTS releases [01:33] owen1: debian thinks "when it is ready" is a fine release schedule [01:34] debian is the base for ubuntu and many packages come directly from there, but debian doesn't have LTS releases and I'm pretrt lazy and don't like to upgrade that often. I still have some dapper servers running too. [01:34] cclausen, i have this error for ssh http://ubuntuforums.org/showthread.php?t=33236 [01:34] i don't know why i'm getting it... didn't do anything that never done b4 [01:34] jaypur: did you just reinstall? that error just means that youe ssh key has changed [01:35] it should tell you the line number in your known hosts file [01:35] cclausen, i got this error, removed everything and reinstalled and it's still [01:35] did you remove your known_hosts file? [01:35] yes but i can't find this file [01:35] cclausen: there are guides for everything out there, i wonder what the best solution is [01:35] should be ~/.ssh/known_hosts [01:36] cclausen: are u working for someone or independent? also, do u pay canonical for support? [01:36] zorzar: there probably is no "best" solution. There are just "works for me" solutions [01:36] owen1: I do not pay. I fix problems myself [01:36] had to manually fix a bad nagios2 package... wasn;t sending emails out due to a path being wrong in teh default config [01:36] cclausen: so why do u care about the LTS? isn't it for companies that need tech-support? [01:37] cclausen, it's empty... [01:37] grrr [01:37] arrgh [01:37] owen1: our campus policy says I must have "supported" OSes on the network [01:37] jaypur: ren your .ssh directory and try again [01:37] (obviously that could be bad if you use SSH keys) [01:38] cclausen: so u'r the sysadmin for the campus. cool. when r u planning to uprade to 10.4? [01:38] owen1: and yes, we might need to call for support one day. good to know that I can if needed. Much better than paying redhat upfront $50 per server. [01:40] cclausen: great. so ubuntu is on a different route than red-hat, in that aspect. [01:40] owen1: in my opinion, yes [01:40] cclausen: i just read that canonical are experimenting with admin certificates. [01:41] owen1: I also REALLY hate RPMs. apt-get is much better about dependancies and there are more packages available in the repos [01:41] cclausen, why is this happening to me... never happened this before... how can i remove all things from ssh and reinstall it? [01:41] jaypur: its a client issue. has nothing to do with the ssh packages themselves [01:41] jaypur: one whatever ssh client you are using, change the known_hosts file and remove the offending key [01:42] Hello all!! I've tried to upgrade my 8.04 server to 10.4, but it no sucess: sudo do-release-upgradeChecking for a new ubuntu releaseNo new release found [01:43] What is wrong?? [01:43] cclausen, sorry if i'm a little bit dumb today, i'm having some family issues right here... so can you tell me please what should i do right now? [01:44] cclausen: ok thanks [01:45] cclausen: how many machines do u manage and what is the strategy for installing/updating them? do u use some kind of a centeralized offline repository? [01:47] owen1: I just have about 13 ubuntu servers, most of them are old laptops in closets to act as DHCP servers [01:47] I do not currently have an automated deployment system [01:47] but I think I'll setup fai now that 10.04 is released [01:47] cclausen, i does not have the file .ssh [01:48] at ~/.ssh [01:48] jaypur: did you cd ~/; mv .ssh dot_ssh ? [01:48] at my home,... .ssh does not exist [01:48] jaypur: its hidden by default you are using ls -lA to look for it? [01:48] ls -lA [01:49] and you are doing this on your ssh client system were you are getting the error? not the ssh server? [01:49] does not exist [01:49] i'm doing it directly to my server [01:49] physical [01:50] jaypur: pastebin your exact error message somewhere [01:51] i type ls -lA .ssh [01:51] is it correct? [01:51] sorry [01:51] =/ [01:52] jaypur: please goto http://paste.ubuntu.com/ and paste the full error message [01:52] cclausen, i'm in my laptop, the error is in the pc.... the error is impossible to access or does not extist [01:52] Hello all!! [01:52] I've tried to upgrade my 8.04 server to 10.4, but have no sucess: [01:52] "sudo do-release-upgradeChecking for a new ubuntu releaseNo new release found"What is wrong?? [01:53] cclausen: can't find a lot of info about FAI but i'll look into it. [01:53] The 10.4 LTS server is not available?? [01:54] Anyone has already done the upgrade from 8.04 to 10.4 ??? [01:54] * cclausen attempt to upgrade from 8.04 to 10.04 right now on a web server [01:55] cclausen, lol cd /home/user/.ssh does not exist lol [01:55] oh, jota. I just had your problem [01:56] ls -a is showing me [01:56] Jota: you need to read more carefully. need to append --devel-release to that command [01:56] jaypur: paste your error message as I requested before. I can't help you without seeing the real error message [01:56] Jota: ERR, SORRY [01:56] cclausen, the error message is: does now exist [01:56] not* [01:56] Jota: its --devel-release [01:57] jaypur: try the ssh command again [01:57] ok... but if I append -d, will I get the final release, or the RC (or beta) release??? [01:58] aaaaah [01:58] Jota: the beta becomes the final release so you get both [01:58] Jota: I thinl everything is release right now though [01:58] why did i need to reinstall it... the last version of ubuntu all things worked right... [01:58] gah! got not enough free disk space error... [01:58] this is not good... [02:00] cclausen: are you sure about that?? I will get the final 10.4 release, as relesed yesterday?? [02:00] cclausen, the file just does not exist, ~/.ssh [02:01] or should I wait a few more days to do the upgrade?? [02:02] Jota: you get whatever is in the repo now. should be release by now [02:02] jaypur: ignore the file does not exist message. re-try the ssh command. what error does ssh give you? [02:02] cclausen, what ssh command??? [02:04] jaypur: the one you originally asked about [02:04] jaypur: or am I really confused? [02:05] cclausen, i'm tired and having some personal problems here, i'm really sorry to bother you [02:05] cclausen, i think i'll reinstall the ubuntu server [02:05] Hey guys. I'm new to software raid. I just installed a new hard drive on a server and did a ubuntu install I told it to use raid1 for 2 disks but only one disk was connected. I want ro connect my old disk, boot the server and copy data from the old drive to the new one before I make the old one part of the raid. If I re connect the old drive and boot off the new one will it auto attach that disk to raid? I don't want to lose the data of the old disk ... [02:05] ... before I copy it [02:05] cclausen, it's easier for me i think and i won't bother you... and at the instalation... i'll select to install the open ssh.... [02:06] New bug: #572719 in kerberos-configs (main) "package krb5-config 1.23 failed to install/upgrade: subprocess installed post-installation script returned error exit status 128" [Undecided,New] https://launchpad.net/bugs/572719 [02:06] ok... [02:06] and, another question: has anyone done the "do-release-upgrade" via ssh?? [02:08] Jota: I did that before from dapper to hardy and it mostly worked... I wouldn't do this from ssh on anything important [02:10] jetole: I think you want to make an offline backup before you do anything else [02:10] jetole: in general, all RAID solutions I've seen want to try and mirror the data immediately, clobering whatever was there previously [02:13] cclausen, I'll reinstall everything thanks for your help man [02:14] cclausen: that sucks but ok [02:14] cclausen: thats also piss poor programming since I didn't tell it which disk to use as the second one but I'm not hear to argue it. I just wanted to know [02:15] jetole: it might work fine, but I think you are better safe to make a backup before attempting anything [02:15] jetole: always err on the side of caution [02:15] I don't have that option since it's a home server and not one at the office or data center but I will try booting off a live CD [02:16] jetole: you don't have backups ? that is problem no matter where the server is at [02:16] and RAID is NOT a backup mechanism [02:16] all our servers at work have 3ware cards except for some old Dell servers that have a dell rebranding of an adaptec I think [02:16] the Dells I use have PERC cards which are re-branded LSI controllers. I have a custom built server with a nice areca controller too. [02:16] cclausen: I know but I'm not rish [02:17] these are PERC too but I thought it was adaptec [02:17] poweredge 2950 III [02:17] 2950 II uses PERC6 [02:17] I think perc 5i but not sure [02:17] oh [02:17] oh, you got the perc5? [02:17] not if you have 2950 II with perc6 I don't [02:17] I have two 2950s with PERC5, but they are original, not the III version [02:18] our 2900 IIIs have PERC6 [02:18] then yeah I really doubt I have perc5 if you have perc6 in II [02:18] but I don;t have linux installed on any of the good server hardware, just in VMs and on old laptops [02:18] lspci would tell you for sure though [02:19] cclausen: linux is our VM. Used to be ESXi 3.5 but I was disapointed in a lot of features and we migrated a year or so ago [02:19] maybe 18 months [02:19] * jetole checks [02:19] I use Hyper-V here. don't like VMWare at all. [02:19] jetole: what features was it missing? [02:20] 01:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04) [02:20] yep, LSI controller [02:20] aetaric: I don't remember now [02:20] i've yet to find anything that esx(i) can't do. [02:21] yeah I remember back when I made the change I had that argument with a bunch of guys in the vmware room [02:21] aetaric: Hyper-V has maximum CPU limits per VM as well as priority settings. I didn't see that in VMWare [02:21] I don't want to have it again [02:21] glad it works for you [02:21] cclausen: it is in there. it is a more advanced feature. [02:22] ah, ok. I figured they would add it somewhere. I haven't looked at VMWare stuff since 2007 [02:22] i just use it for vmotion....so... [02:22] cclausen: well I know since I left they came out with vmware ESXi 4 [02:22] and I still don't like the crazy network adapters that VMWare adds on teh guests [02:22] we don't have SAN gear here, so vmotion wouldn't work anyway [02:22] yeah... it is a bit complex... [02:23] I've not found an affordable multiple VLAN redundant SAN solution [02:23] Ah I did our first SAN setup ~8 months ago and another one since [02:23] one in the office and one in the DC [02:23] cclausen: you don't need a san.... iscsi would work, or nas [02:23] everything is designed to run on the same subnet in the same datacenter and I need cross-campus redundancy [02:23] aetaric: iscsi is san [02:23] aetaric: yeah, but what is the point if its a single point of failure? [02:24] jetole: technically, iSCSI is just block-level storage. we have software iSCSI targets on a few systems [02:24] san is block level storage over networking [02:24] san is almost more but iscsi is san [02:24] well, if you put it that way, yes, that is iSCSI [02:24] *almost always [02:24] as nas is filesystem over the net san is block level which covers iscsi and ata over eth [02:25] I know it's rediulously simple san but it is san [02:25] *rediculously [02:25] still don't know if I spelled that right [02:25] jetole: I'm thinking more about the actual storage on the backend, not the protocol used [02:26] you mean like clusters of DAS etc [02:26] sort-of [02:26] I mean the ability to migrate volumes betweens disks in different physical locations while the data is online [02:26] actual storage management [02:27] was looking at nexenta stuff, but it still cost a bit too much [02:27] ah, for management we use linux [02:27] we have some expensive file servers and maybe getting some DAS extensions later this year [02:28] but linux does what we need [02:28] I use Microsoft Dfs for end-user network CIFS shares. works very well for Windows clients [02:28] oh god know [02:28] I use DFS too [02:28] I guess I need to test if Linux has Dfs client support yet... [02:28] I hate it [02:28] no [02:28] no it doesn't [02:28] use openafs [02:28] haha [02:28] I'm a chanop on #openafs [02:28] :-) [02:28] I hate dfs and when I get the time I will be replacing it with openafs [02:29] I know very little about openafs but I use DFSr and I despise it [02:29] openafs doesn't have read-write replication [02:29] thats what I was refering too, I forgot DFS does not mean DFSr [02:29] be aware of that [02:29] I do use the newer Dfs namespace and Dfs-R replication in 2003 R2 [02:29] the older windows 2000 stuff kind of sucked bigtime [02:29] I use DFSr on 2008 [02:30] I used it on 03 [02:30] not 2000 [02:30] brb [02:30] yeah, I need to upgrade to 2008 [02:30] err, 2008 R2 [02:31] back [02:31] yeah we don't have any R2 yet [02:31] anyways, doesn't openafs do what DFSr does? [02:31] I'm doing the lucid upgrade on a 2008 R2 hyper-V VM right now... [02:32] no, openafs doesn't have ANY read-write replication at all [02:32] just read-only replication [02:32] and its not realtime [02:32] you need to manually "vos release" [02:32] oh that sucks [02:32] yeah, pretty much [02:32] its on the roadmap for afs, but won't be production ready for a couple of years [02:33] so until I see something else, DfsR seems to be the best available for fairly low cost [02:33] I use drbd mostly which does real time read/write at the block level which works great with ocfs and also you can do realtime io on glusterfs to more then two hosts but these are not windows options [02:33] well glusterfs may be [02:33] drbd definitly is not [02:34] so with openafs you can only write on the master server? [02:36] sort-of [02:36] its worse than that [02:36] the afs client prefers the read-only volume be default [02:36] so the RW one has a different path [02:43] your downplaying afs a lot for someone whose an op in that room [02:44] well, its useful, but not as a Dfs replacement [02:44] especially for read-write replication [02:44] and its worse than that, I'm hosting the afs conference this year: http://workshop.openafs.org [02:45] sounds to me like the only real perk is cross platform deployment but what situation would say openafs is good for. Like what type of real world usage would you recommend openafs for? [02:45] well, I just tried an upgrade from 8.04 to 10.04 and that failed catastrophically. apaprently the installer didn't like my old kernel... [02:45] jetole: if you are using it for read-only distribution [02:45] meh, I gave up on the upgrade option years ago. I always do fresh installs now [02:46] I know a company that uses AFS to globally deploy new software to a large number of servers in 2 seconds [02:46] AFS callbacks ensure that new data is read at the same time across all of the servers [02:46] what about say, web content on a server farm? [02:46] that too [02:46] pictage does that [02:46] and I would run openafs server on the same host as ftp [02:47] you should probably ask more in #openafs [02:47] we're probably way off topic for this channel [02:47] another night. I'm going to bed in 10 [03:04] cclausen, re installing :D almost done [03:04] jaypur: cool [03:04] I also re-started the upgrade process [03:05] I first installed the default linux-image-generic kernel in 8.04. I think I'll have better luck with this than the self-built xen kernel I was using before... [03:05] hm [03:05] (luckily going backwards is easywith a VM) [03:06] the 10.4 is with a new resolution i think [03:06] probably different video drivers [03:12] cclausen, finished.... [03:12] now i need to see the ssh if it's working... [03:12] excellent. I'm getting farther in this install too. I think that the installer crashed on me last time and my system was half upgraded [03:15] now i'll change the ssh port [03:15] jaypur: why are you changing the ssh port? [03:16] because my internet service blocks ports like 22, 80.... [03:16] sux BRAZILIAN INTERNET lol [03:16] ah, ok [03:16] that is a good reason :-) [03:17] changed [03:17] do i need to restart ssh? [03:17] I would [03:17] how do i restart the app:? [03:17] invoke-rc2.d ssh restart [03:18] restarts the sshd server [03:18] err, hmm. might not be a "2" in the command [03:18] why the invoke-rc2.d? [03:18] its invoke-rc.d ssh restart [03:18] same as running /etc/init.d/ssh restart [03:19] damn i can't connect [03:19] what error ? [03:20] ssh: connect to host IP port 1010: Connection refused [03:20] firewall ? [03:20] aaaaaaaw noooo [03:20] not again [03:20] @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ [03:20] now i restarted the app right [03:20] what client are you sshing from? [03:20] ... [03:21] and again [03:21] yes, that is an expected error [03:21] from ubuntu the normal ssh [03:21] you are sshing from your ssh to your server ? [03:21] here we go again [03:21] (e.g. to localhost ?) [03:21] im sshing LOL from my laptop to my server [03:21] same internet [03:21] you need to change the known_hosts file on the laptop [03:21] this error has nothing to do with the server side at all [03:22]
