[00:06] <kgoetz> proprietarysucks: i think you can, i dont know how. (havent dealt with those redhatty things before)
[02:52] <pschulz01> Greetings all! I have an interesting server problem..
[02:54] <pschulz01> We (work) are installing a new server and at the same time preparing some backup hardware should somethign go wrong..
[02:54] <pschulz01> The plan is to do nightly backups to a disk, and then be able to swap in the new hardware with the new disk, if required, and take off from where the backup was done.
[02:56] <pschulz01> There are issues with 'udev' wanting to keep network device names around (easy to fix) and an issue with sysklogd not starting up properly.
[03:01] <pschulz01> Hm.. I'll send my question to the mailing list.
[04:26] <Zylstra555> are there any free, safe, good external SMTP servers, if you dont want to create your own?
[04:27] <sommer> Zylstra555: usually your ISP will allow you to use theirs.
[04:27] <sommer> there may be limits though
[04:27] <Zylstra555> sommer: Righto, I shall need to contact them
[08:02] <sergevn> How are the experiences with JeOS here in the channel? :)
[08:05] <kraut> moin
[08:32] <soren> sergevn: What do you want to know?
[08:39] <Burgundavia> soren: should I assign ebox bugs to you?
[08:41] <soren> Burgundavia: Nah. I'll look at them, when I get to eBox on my list anyway.
[08:41] <soren> Burgundavia: And if someone else feels like looking into it, they're more than welcome :)
[08:41] <sergevn> soren: If someone has the "common" problems like with any new distro
[08:42] <soren> sergevn: It's not exactly a new distro, but yes, I have to admit it has a few annoying quirks.
[09:13] <tjaalton> whee, a newer nfs-utils from debian fixes nfs mounts.. I'll merge it now (mathiaz being absent)
[09:15] <soren> tjaalton: Great, thanks.
[09:15] <tjaalton> huh, there was a sync request too, but that's bogus
[09:15] <tjaalton> I'll close that once done
[09:21] <tjaalton> actually, it could be synced, since the only change is for initscripts Depends, which is now obsolete
[09:23] <tjaalton> uh no
[09:24] <tjaalton> not before sysvinit is merged :)
[09:26] <soren> tjaalton: So what are you waiting for? :)
[09:26] <tjaalton> soren: dput to finish :)
[09:26] <soren> (You're not identified to nickserv, by the way)
[09:26] <soren> tjaalton: Heh :)
[09:26] <tjaalton> I'm not going to merge sysvinit if that's what you meant :)
[09:27] <tjaalton> oh right, I changed my nick a couple of weeks ago..
[09:28] <tjaalton> done
[09:30] <tjaalton> I _think_ keybuk want's to deal with sysvinit himself ;)
[09:33] <soren> tjaalton: That was indeed what I meant, yes :)
[09:58] <mikone> hey, for some reason my gutsy machine (just did an upgrade from feisty) does not "recognize" the root user anymore. when booting it tells me "only root can do that" several times when its supposed to mount the drives.
[09:58] <soren> All drives?
[09:58] <Kamping_Kaiser> sounds like stuffs running as the wrong user, not lacking root
[09:59] <mikone> yes.
[09:59] <mikone> the boot process itself?
[09:59] <Kamping_Kaiser> you using any fancy crypto stuff?
[09:59] <soren> mikone: What is the precise output you get? Can you tell which commands it's trying to run?
[10:00] <mikone> yes of course.. it will take a while because i cant access the computer remotely
[10:06] <mikone> okay, first of all grub is loading the kernel image (starting up, loading... please wait), after that, kinit resolves the swap partitions name and searches for an image which it should resume from (none is found) and then it tells me that "No resume image (was found), doing normal boot" - the very next message already is "mount: only root can do that"
[10:06] <mikone> so it probably tries to mount the partitions listed in fstab...
[10:06] <soren> Ok, so you can't actually see the commands it's trying to run.
[10:06] <soren> Can you boot it without "splash quiet" on the kernel command line?
[10:07] <mikone> yes, i will change it
[10:10] <mikone> the first mounting error appears immediately after executing /scripts/init-bottom but it does not tell me how the mount command does look like
[10:11] <mikone> and i can't access any logs since it is not able to mount the partition which is bound to /var and the root partition itself is read only...
[10:20] <soren> mikone: This sounds very odd indeed.
[10:21] <soren> mikone: Is there anything interesting about your setup?
[10:21] <soren> How is it different from a standard install?
[10:21] <mikone> yes, i've been changing the pam.d and nsswitch settings but resetted the settings to default already
[10:22] <soren> What were your changes to nsswitch?
[10:22] <mikone> they've been working before - i have a ldap server handling some user accounts but root still is in passwd of course
[10:22] <mikone> i added ldap as the third place to lookup
[10:22] <mikone> after compat and files
[10:23] <mikone> do you think its something about nsswitch?
[10:23] <soren> Could be.
[10:23] <soren> nsswitch defines how to resolve uid <-> usernames, for instance.
[10:24] <soren> I *shouldn't* matter, of course, but it might have.
[10:24] <mikone> yes, i think i understood it this far though i'm not sure how it could affect the boot process when only having a third place for resolving uids/names
[10:25] <mikone> i will give it a try and post my results as soon as i'm done
[10:25] <mikone> thanks for now :)
[10:25] <soren> Well, fixing it now won't help much, I think.
[10:25] <soren> ...although..
[10:26] <soren> Well, it's hard to tell what the problem actually is, so it's hard to guess what would fix it. :)
[10:26] <mikone> what do you mean by "fixing it now"? doesn't it make a difference when changing the nsswitch configuration from a live cd or stomething?
[10:26] <mikone> yes, the most terrible thing is not having access to any log files :)
[10:26] <soren> That could work.
[10:27] <soren> Fix the nsswitch.conf and run update-initramfs -u from a chroot into the file system.
[10:27] <mikone> that probably is what i was missing. update-initramfs forces it to change what?
[10:28] <soren> It updates the initramfs :)
[10:28] <soren> It's the early userspace stuff that loads the drivers needed to mount your root file system.
[10:30] <soren> Again, it's hard to tell what the problem is, and doing this can't really make things worse :)
[10:33] <mikone> well, changing nsswitch to look up groups/users in files only did not help. i will try to use compat and files only though i don't know what compat means :)
[10:35] <mikone> this is what happens when you're doing things you don't know anything about.. i think that's the lesson for today.
[10:39] <mikone> do you think "update-passwd" could help too or does this not affect the early userspace?
[10:42] <soren> mikone: Doesn't matter.
[10:44] <mikone> gladly i made a backup of the most important configurations prior to updating... i think i will reinstall the system now before wasting your and my time anymore. thank you very much for your help!!
[10:47] <soren> It's not trouble. Really.
[10:47] <soren> We might uncover an actual problem that needs to be fixed and even learn something in the process :)
[10:49] <mikone> okay, that's true.. it would be great if it was possible to get some log files but i can't imagine how to do this when not having a root user at all :)
[10:51] <mikone> just as a sidenote: when starting in recovery mode i end up having a terminal which predicts to be root@server. but as soon as running any commands requiring root permissions like mount it tells me "mount: only root can do this"
[10:52] <soren> Do you have that prompt around still?
[10:52] <mikone> i may boot in recovery mode again, that's not a problem
[10:52] <soren> Cool.
[10:52] <soren> Do that, please.
[10:52] <mikone> of course :)
[10:55] <soren> ...and say when it's ready.
[10:56] <mikone> okay, that's funny. last time i've been running the knoppix live cd to perform the update-initramfs i also assigned a password to the root user. when starting in recovery mode now, it asks me for the root password (which it did not do formerly) and it really seem to check the password
[10:56] <mikone> however, i'm ready :)
[10:57] <soren> That's the way sulogin works.
[10:57] <soren> If the root user has a disabled password, it just dumps you at a root prompt. If it's got an actual password it asks you for it.
[10:57] <soren> Ok, what does id say?
[10:58] <mikone> after asking for the password it tells me that "bash: groups command not found" and the same for dircolors
[10:58] <mikone> but nothing else
[10:58] <mikone> and as it did before there are a lot of error messages from commands involved by the boot process which require root credentials
[10:58] <soren> Ok try "id -u" instead.
[10:59] <soren> Oh..
[10:59] <soren> Now I know what you mean.
[10:59] <soren> Just type "id" and tell me about the output.
[10:59] <soren> I didn't mean "it" :)
[10:59] <mikone> it could not find the command
[10:59] <soren> Ah.
[10:59] <mikone> is it somewhere below /usr ?
[10:59] <soren> Yes.
[10:59] <mikone> :(
[10:59]  * soren things
[10:59] <mikone> i'm afraid this partition is not available
[10:59]  * soren thinks
[11:00] <mikone> though i could copy its contents with knoppix
[11:00] <soren> That's ok. We'll figure it out.
[11:00] <mikone> i mean the contents of var partition to root partition
[11:00] <mikone> erm, usr
[11:00] <soren> Ok, run "mount", locate your root partitino.
[11:00] <soren> What's in the parentheses?
[11:01] <mikone> rw,errors=remount-ro
[11:01] <soren> Ok. What are the permissions on /bin/mount ?
[11:02] <mikone> oh, i think i see the problem
[11:02] <mikone> its uid 1501 which is the root user in the directory (ldap)
[11:02] <mikone> i mean thats the owner
[11:03] <mikone> though "world" and "group" are allowed to read and execute
[11:03]  * soren is on the phone
[11:03] <mikone> -rwxr-x-r-x
[11:04] <mikone> it's not like i'm in a hurry... i already told my boss that i probably have to set it up again :>
[11:04] <Kamping_Kaiser> theres always `grep `whoami /etc/group /etc/passwd`` if you need to work out who you are :)
[11:04] <mikone> i'll give it a try
[11:05] <soren> Kamping_Kaiser: No, that's not good enough.
[11:05] <mikone> whounfortunately whoami is not available too
[11:05] <Kamping_Kaiser> gah. whoami is under /usr/ *grin*
[11:06] <Kamping_Kaiser> soren, i havent read the full scrollback... perhaps i should
[11:06] <soren> Kamping_Kaiser: Even if it wasn't, that wouldn't be good enough.
[11:06]  * Kamping_Kaiser forgot the channel was active :$
[11:06] <mikone> :)
[11:06] <Kamping_Kaiser> back in 5-10 min ;)
[11:06] <Kamping_Kaiser> readin
[11:06] <Kamping_Kaiser> g
[11:06] <soren> mikone: So somehow someone managed to chown root:root /bin/mount  and change it to the ldap root user?
[11:06] <mikone> shall i copy the contents of the partition mounted to /usr to the root partition now?
[11:07] <soren> No, don't bother.
[11:07] <mikone> yes.. it probably looked up the ldap root user before the actual root user
[11:07] <soren> chown 0:0 /bin/mount ; chmod 4755 /bin/mount
[11:07] <mikone> it could have happened while upgrading
[11:07] <soren> mikone: ...that really shouldn't happen.
[11:07] <soren> mikone: If you added ldap at the end.
[11:08] <mikone> i did
[11:08] <soren> mikone: And besides: Nothing should be ch{mod,own}ing /bin/mount
[11:08] <soren> chown 0:0 /bin/mount ; chmod 4755 /bin/mount  <--- Those two commands are likely to fix everything.
[11:08] <mikone> yarr, root is read only. i have to restart and boot from a recovery cd
[11:08] <soren> No, it's not.
[11:08] <soren> You said the parentheses said rw?
[11:09] <mikone> maybe an error appeared and it was remounted
[11:09] <soren> dmesg?
[11:09] <soren> Oh, hang on.
[11:09] <soren> cat /proc/mounts
[11:09] <soren> instead of running "mount"
[11:10] <soren> There might be several that looks like they're mounted on /. You need to find the one with the right block device at the start of the line.
[11:10] <mikone> you're right, it's mounted as rw
[11:10] <mikone> ah okay
[11:10] <mikone> i'm not sure about the uuid but there is one partition mounted read only
[11:10] <mikone> this probably is the root partition
[11:10] <mikone> yes it is
[11:10] <Kamping_Kaiser> bloody nss* stuff. caused me some issues on my server too.
[11:11] <soren> mikone: Is /dev/shm mounted?
[11:11] <mikone> nope
[11:11] <soren> Crap.
[11:11] <Kamping_Kaiser> chown 0:0?
[11:11] <soren> read only filesystem.
[11:11] <mikone> and yes Kamping_Kaiser, but one really should read some more documentations before playing around :>
[11:12] <mikone> do you think starting the recovery cd could help?
[11:12] <Kamping_Kaiser> mikone, hehe. lamont saved my but by telling me to use nscd, magically my libnss-ldap worked, pity it wont help you ;)
[11:12] <soren> mikone: Sure, I just wanted to not have to do that. :)
[11:13] <Kamping_Kaiser> theres a way to remind / rw isnt there ? sometyhing like `mount -o rw /dev/rootDeviceHere`?
[11:13] <soren> Yes, but the problem is that mount is suid another user.
[11:13] <mikone> :)
[11:14] <mikone> i'm gonna reboot and put the proper access permissions on /bin/mount
[11:14] <Kamping_Kaiser> ah... is it time to chroot this in a live cd and run chkrootkit yet? ;)
[11:14] <soren> Kamping_Kaiser: And it's -o remount,rw
[11:14] <soren> Hang on...
[11:14] <mikone> sure :)
[11:15] <soren> mikone: You say it's -rwxr-xr-x ? Not -rwsr-xr-x ?
[11:15] <mikone> uhh, i THINK its -rwxr-xr-x but i just rebooted.. it will take a minute or so
[11:15] <Kamping_Kaiser> i was supprisingly close. thanks for the correction though
[11:16] <soren> Kamping_Kaiser: :) Without the remount option it'll just say "already mounted. Go away. kthxbye"
[11:17] <Kamping_Kaiser> soren, fair enough :) at least its nice enough to tell you it wont, unix's arnt always that nice :)
[11:19] <mikone> soren, it definitely is -rwxr-xr-x
[11:19] <mikone> i changed to ownership now
[11:20] <soren> mikone: In that case, mounting should have worked.
[11:20] <soren> Meh. Try it anyway :)
[11:21] <mikone> okay ;)
[11:21] <mikone> running the chmod command is still required?
[11:21] <mikone> and if so, for umount to? because this file seems to have the same problem...
[11:25] <mikone> YOU SAVED MY DAY!
[11:26] <mikone> i'm not going to spend hours on reinstalling the whole system
[11:26] <mikone> you are GREAT!!
[11:26] <MenZa> soren is, indeed, great.
[11:26]  * MenZa worships soren.
[11:26] <MenZa> soren, did you ever go through the ubunut-dk members' list?
[11:26]  * soren laughs
[11:27] <soren> MenZa: No, someone said he'd send out the minutes from the meeting. I figured I'd do it then.
[11:27] <MenZa> oh wait.
[11:27] <MenZa> #ubuntu-server, right. >_>
[11:27] <MenZa> The.. minutes?
[11:28] <soren> "referatet" :)
[11:28] <MenZa> The summary ;)?
[11:28] <MenZa> Hmm
[11:28] <soren> It's called "minutes". Go figure.
[11:28] <MenZa> Yeah, I haven't received that yet
[11:28] <Kamping_Kaiser> *fanboys soren *
[11:28] <mikone> i just noticed :)
[11:28] <MenZa> Interesting, soren
[11:29] <MenZa> I still have the logs, if you want the names now, or we could wait for sbc's referat.
[11:29] <MenZa> ;P
[11:29] <MenZa> oh wait
[11:30] <soren> I've got plenty of logs :)
[11:30] <MenZa> I don't have the logs; they're on my desktop computer.
[11:30] <MenZa> Alright. :)
[11:30] <soren> Bah, I'll do it now.

[12:31] <soren> Hi, ivoks.
[12:31] <ivoks> hi
[12:32] <_ruben> any thoughts on bug #141601 yet, i added some info (output of ps)
[12:32] <ubotu> Launchpad bug 141601 in tasksel "tasksel packages stays at 100%" [Undecided,New] https://launchpad.net/bugs/141601
[12:33] <soren> _ruben: Nope.
[12:35] <_ruben> soren: just curious mostly, since tasksel isnt something you'd use daily .. but having a (little bit more) bug-free release would be nice ;-) .. any extra info i could gather to help this case?
[12:36] <soren> _ruben: i've poked the apt dude. He might be able to work something out.
[12:36] <_ruben> ah ok
[12:38] <ivoks> i got bitten by that bug
[12:38] <ivoks> i tought i fscked something with my patch, but looks like i'm not alone :D
[12:38] <_ruben> heh
[12:44] <soren> Hmm... I think it's a debconf issue, actually.
[12:51] <Gargoyle> Can I use crossover cables with nic bonding in the modes for increased performance?
[13:03] <_ruben> Gargoyle: in theory i'd say yes, but never tried in practice
[13:05] <soren> _ruben: ... I think I've fixed it.
[13:05] <soren> Gargoyle: "in the modes" ?
[13:09] <Gargoyle> soren: Yeah, like mode 1 is just fail over, 1 nic does all the work till it fails then the other one takes over
[13:09] <soren> Ah.
[13:09] <soren> So the question is whether or not it works with crossover cables?
[13:12] <_ruben> soren: nice .. if only i could get WoL to work on that box i could've tried a possible fix right away :/
[13:12] <_ruben> the box is supposed to support WoL, just doesnt seem to work :/
[13:12] <soren> _ruben: Etherwake works better for me.
[13:12] <Gargoyle> soren: Yeah, but not mode 1, I was thinking of the link aggregation modes
[13:13] <soren> _ruben: I have not hardware that supports WoL as implemented in the wakeonlan package.
[13:13] <_ruben> soren: i've used the 'wol' command/package on openwrt and some windows tool as well
[13:13] <soren> Gargoyle: I've not understood your question. If you're asking if bonding works with crossover cables, then the asnwer is yes.
[13:14] <soren> Gargoyle: It's quite agnostic to that sort of hting.
[13:14] <soren> And typing is hard.
[13:14] <soren> _ruben: Ok. I think wol on openwrt does the same as etherwake.
[13:15] <_ruben> soren: ah
[13:15] <soren> _ruben: Which is good.. :)
[13:16] <_ruben> soren: its a dell machine, have read mixed experiences with wol on the 'net and dells
[13:16] <soren> Gargoyle: If you've got Linux on both ends, I don't even think they both have to be ethernet. They could be ppp+wifi+ethernet+atm+whatever.
[13:17] <Gargoyle> ohhh
[13:20] <frippz> I'm looking to upgrade the NIC in an Ubuntu-server to a gigabit variant. any recommendations?
[13:30] <soren> frippz: Intel cards are usually a fairly good bet.
[13:30] <_ruben> no probs with intel here either
[13:33] <frippz> great, thanks guys. I suspected that Intel would be a good bet :)
[13:51] <mruiz> Hi all. I'm using Ubuntu Dapper and I want to connect Active Directory with Squid through squid_ldap_auth. I tried to test the connection using /usr/lib/squid/ldap_auth but I can't obtain results... I used -d (debug) flag without output.
[13:52] <_ruben> hmm ... how do i get my hands on "the apt from gutsy-proposed", as suggested in bug #141601

[15:10] <nealmcb> soren - on saturday my hard drive got messed up, while I was nailing down some more info on my gutsy/qemu/jeos experiences.  But when I rebooted in recovery mode (and with no silly splash screen), I got this:  alert! /dev/disk/by-uuid-ad2c6.......2a3 does not exist, dropping to a shell.  I was uploading the qcow2 with some nice snapshots, but that didn't complete before my system went down....
[15:11] <nealmcb> by the way, I had needed ata_piix.blacklist=yes on boot to do the cdrom install in the first place, but I didn't seem to need that when booting the installed disk.
[15:24] <hoarycripple> hello
[15:25] <somerville32> lo
[15:25] <hoarycripple> on #ubuntu I was informed that ubuntu server contains a server specific kernel and no gui.  I'm assuming it is possible to install X, but what are the kernel differences?
[15:26] <hoarycripple> is there somewhere I can read about the differences?
[15:26] <nealmcb> http://www.enterprisenetworkingplanet.com/netos/article.php/3710641
[15:27] <hoarycripple> thanks!
[15:27] <nealmcb> :-)
[15:28] <sommer> nealmcb: that link is everywhere... doh
[15:29] <nealmcb> sommer: yeah - I'm looking forward to having that documented on our own pages ;-)
[15:31] <sommer> nealmcb: I plan on asking a couple of quesitons concerning that in the meeting
[15:31] <nijaba> sommer: please do :)
[15:32] <hoarycripple> ok, so I looked at the diff.  looks like all the modules for sound etc are being built in both server and desktop kernels.
[15:32] <nealmcb> hoarycripple: right - pretty minor differences
[15:32] <nealmcb> ...in terms of functionality - mainly tuning
[15:33] <hoarycripple> and are the package lists the same?  I don't see different repos for server edition.
[15:37] <nealmcb> hoarycripple: same repos, different default packages.  and most of us don't recommend x11 on a server :-)
[15:41] <hoarycripple> i'm actually planning on trying it on a desktop computer.  just interested to see if I'll notice any difference.  especially with the deadline scheduler and preemption turned off
[15:42] <hoarycripple> i've got a quad xeon for the desktop which does mostly video editing with cinelerra and is also used as a digital audio workstation (ardour).
[15:43] <hoarycripple> would you guys just recommend sticking to desktop kernel?
[15:43] <nealmcb> I'm no expert but my guess would be that more frequent clock interrupts etc would make it more responsive for interactive editing with the desktop kernel
[15:46] <hoarycripple> thanks for the info.  i'm now having second thoughts about server edition :)
[15:48] <nealmcb> it's great for servers!
[15:49] <nealmcb> you can switch the kernel later if you like, in either direction
[15:50] <hoarycripple> ahh, so I can just apt-get the desktop kernel if necessary?
[15:50] <nijaba> hoarycripple: exactly
[15:51] <nijaba> but I would recommend the other way around to start with
[15:51] <hoarycripple> ok, cool.  that decides it...going to give it a try.  thanks guys.
[15:51] <hoarycripple> oh, just one more thing:
[15:52] <_ruben> hmm .. the stuff that article mentions concerning sudo and all seems a bit flawed, no?
[15:52] <hoarycripple> in desktop edition, no matter what I tried, normal users were still able to shutdown the computer. (followed many instructions from ubuntuforums and blogs etc...)  I'm guessing that normal users cannot shutdown/reboot server.  Is this correct?
[15:55] <nijaba> Server meeting in 5m in #ubuntu-meeting
[15:55] <nealmcb> _ruben: you mean the first part of that article?  yeah - I think the way sudo works in ubuntu is great, and she's just missing some techniques
[15:59] <nealmcb> hopefully we can also get some progress on this: https://bugs.launchpad.net/ubuntu-doc/+bug/122297
[15:59] <ubotu> Launchpad bug 122297 in ubuntu-doc "Server Guide draft has higher Google rank than released version" [Medium,Confirmed]
[16:03] <danp> for a given release, does the release-updates collection include the release-security collection?
[16:25] <kshah> when i first installed ubuntu-server I created my user and my pass which is the root pass, now I want to grant someone else root access, is placing them in sudoers enough? Or should I change the root pass (if so, how?) and make myself a new pass and place myself in sudoers?
[16:28] <mralphabet> etc/sudoers I believe
[16:33] <kshah> mralphabet: After install is my password and the root password the same? since I'm not in the sudoers file but I can run commands as sudo
[16:34] <somerville32> kshah, no
[16:34] <kshah> so if I want to grant someone else root access how should I do that?
[16:34] <somerville32> kshah, You are in the sudoer file
[16:34] <kshah> I am>?
[16:34] <somerville32> kshah, admin (a group) is a member of sudoers
[16:34] <kshah> oh
[16:34] <mralphabet> sudo password != root password
[16:34] <kshah> oh i see...
[16:34] <kshah> i see
[16:35] <somerville32> "sudo password" == your password
[16:35] <kshah> so adding a user to sudoers via sudo visudo is ...
[16:35] <mralphabet> dandy
[16:36] <mralphabet> will solve most if not all of your questions
[16:36] <kshah> so they can run commands as sudo with their own pass?
[16:36] <kshah> all i have to do is adduser, and add that user to sudoers and they can do everyhing i can do?
[16:37] <mralphabet> you should be fine
[16:37] <kshah> great thx
[16:40] <leonel> For an ubuntu cluster  for  math calculations is  redhat-cluster-suite   right for the task ?
[16:43] <soren> leonel: Depends on your setup really. Do they use shared storage? How do the computing tasks get assigned to nodes?
[16:43] <leonel> good question   I was asked  what was the  ubuntu cluster  way  to do it
[16:43] <leonel> and found that package in main
[16:45] <soren> redhat-cluser-suite is indeed the clustering software of choice in Ubuntu. However, depending on your setup, you might not need anything like that at all.
[16:46] <leonel> soren: here arrived  kab  which asked me  that  ..
[16:46] <leonel> kab:  can you explain your needs more  ?
[16:46] <kab> hi soren
[16:46] <soren> HEllo
[16:47] <kab> ok, I was talking with leonel about a linux cluster with ubuntu
[16:48] <kab> a PhD Chemical that need a Cluster ask me about that
[16:48] <kab> I don't know nothing about Clusters
[16:49] <kab> Mr Chemical said me that they want to run RedHat XYZ Version because it have a Cluster Solution
[16:49] <kab> And I begin google for ubuntu solutions like redhat
[16:50] <kab> Leonel said me that ubuntu has the same solution (redhat-cluster-suite)
[16:50] <soren> That's right.
[16:50] <kab> so, thats very nice to me
[16:50] <soren> Well, if he actually knows what he's doing, and he knows that he needs rcs, Ubuntu will work just fine.
[16:50] <kab> Mr Chemical is using a privative software called Gaussian
[16:51] <kab> but he needs too, program in any language that can do paralels jobs
[16:51] <kab> I suggested python
[16:52] <kab> so the cluster is for do calculus (Mathematics)
[16:53] <kab> the nodes are heterogenous
[16:55] <kab> soren this is the software that mr Chemical wants to run http://www.gaussian.com/
[16:55] <soren> kab: Well, the thing is that if they don't share any ressources, there's no point. I've seen clustering solutions where a job server just advertises jobs, and nodes pick them up and send the result back. If they don't respond within a reasonable timeframe, the job gets offered up for another node to work on.
[16:56] <soren> In that case, there's no need at all for something like rcs.
[16:57] <soren> ..because they don't share any ressources, so all you really need is a monitoring facility to discover dead nodes so that you can replace them.
[16:57] <kab> soren ok
[16:58] <soren> Without any details about what you actually need from the clustering solution, it's hard to advice you properly, I'm afraid.
[16:59] <kab> soren let me study a little more, and I will ask you, sure if you want
[17:02] <soren> kab: Well, if you feel you've got all the info you need from me, I'm fine. :)
[17:03] <danp> is there any ubuntu-specific info for setting up RCS things in ubuntu?
[17:03] <danp> i'm going to be testing clustered samba with it soon
[17:05] <soren> danp: Not that I can think of, no.
[17:05] <soren> danp: We follow upstream (RedHat) quite closely, so their docs should be fine.
[17:05] <danp> cool
[17:19] <nealmcb> soren: did you see my note a few hours ago here about qemu, jeos and /dev/disk/by-uuid-ad2c6.......2a3 does not exist, dropping to a shell
[17:20] <soren> nealmcb: Yes. I'm still trying to wrap my head around the fact that it works with images created by the vm-builder and not if you install from a CD.
[17:20] <nealmcb> boy that vm builder is good stuff :-)
[17:21] <nealmcb> I'm just trying to get my laptop back in operation so I can play some more with it
[17:22] <nealmcb> zul: have you tried the jeos iso with xen?
[17:23] <zul> nealmcb: nope im still trying to port xen to 2.6.24
[18:05] <proprietarysucks> since there is apparently no way to stop ubuntu from stopping an automatic kickstart-based installation to ask if it's ok to continue since it can't contact security.ubuntu.com, I mirrored the entire security.ubuntu.com website locally and now I'm having trouble getting the host file on the installer changed
[18:06] <proprietarysucks> anyone have a working pre script on ubuntu or know how to edit the hosts file in some other way?
[18:13] <mralphabet> proprietarysucks: can you echo x.x.x.x s.u.c >> /etc/hosts ?
[18:17] <proprietarysucks> that's the first thing I tried
[18:17] <proprietarysucks> I think I have finally found my answer however
[18:17] <mralphabet> oh?
[18:17] <proprietarysucks> for everyone in here's information I'll share =]
[18:17] <proprietarysucks> kickstarts for ubuntu have the added command 'preseed'
[18:18] <proprietarysucks> so in your normal, redhat-style kickstart for ubuntu you can simply add 'preseed apt-setup/security_host string' anywhere
[18:19] <proprietarysucks> that will simply disable the security updates
[18:19] <proprietarysucks> verifying right now
[19:11] <jeward> How can I install the server kernel on gutsy so that I can use all 4G of RAM in my laptop?
[19:15] <jeward> just install linux-server?
[19:15] <leonel> linux-image-2.6.22-14-server
[19:16] <leonel> my  generic  version :CONFIG_HIGHMEM4G=y
[19:16] <leonel>    
[21:01] <jcengineer> what happened to /etc/initab ?
[21:02] <fujin_> anyone know where I might procure a 7.10 'driver cd'?
[21:03] <ivoks> jcengineer: ubuntu doesn't use sysV
[21:04] <jcengineer> how do i setup a console on a serial then /
[21:05] <ivoks> jcengineer: check out /etc/event.d/
[21:07] <jcengineer> hm tty1 is allready running ?
[21:08] <jcengineer> it doesn't start at tty0?
[21:08] <ivoks> you are asking for ttyS1, right?
[21:08] <ivoks> or ttyS0
[21:08] <ivoks> ttySX != ttyX
[21:08] <jcengineer> yes sorry
[21:08] <jcengineer> i dont see it there
[21:09] <ivoks> create it
[21:09] <ivoks> you can just copy tty1 to ttyS0
[21:09] <ivoks> and edit it
[22:27] <CharlieSu> Does anyone know how to take a SSL certificate that was generated for Apache and turn it into something that can be used by Tomcat?  I'm not proxying connection through Apache..
