[00:41] <ari_stress> morning all :D
[02:12] <akn> hi, is anybody on who can give me current info on lts.conf?
[16:06] <ab0oo> any NFS fat client gurus around?  I have a question about ssh host keys with a nfsroot and multiple clients.
[16:07] <laga> just ask
[16:07] <ab0oo> ok, if I have a bunch of clients that all mount the same nfsroot, and they all run SSH, then they all get the same SSH host key, which is non-optimal.
[16:08] <ab0oo> is there a way (i.e. a config option to sshd) to get each host to use it's own key?
[16:09] <laga> good question :) i'll be facing the same issue soon..
[16:09] <ab0oo> I'm not sure #edubuntu is the right channel, but the project seems to have more nfsroot expertise than I can find anywhere else.
[16:09] <laga> ab0oo: there's a different problem, too: how do you make the clients keep their host keys if they reboot?
[16:09] <ab0oo> then, unless you have a bunch of identical hardware, you'll also face the xorg.conf problem, too. :)
[16:10] <ab0oo> well, X server has a slick little secret:  it will read xorg.conf.<hostname> for x configuration, so you can have per-host xorg.conf
[16:10] <laga> ab0oo: no, that'll be OK. ubuntu has lots of autoconfiguration magic and each client will have his own writeable nfs share which is merged with the root share using unionfs :)
[16:10] <laga> oh, nifty.
[16:11] <ab0oo> which is GREAT, unless you use nvidia's proprietary driver, which won't load the nvidia kernel module unless it finds nvidia in the /etc/X11/xorg.conf file.
[16:11] <laga> ab0oo: that's an ubuntu-specific hack
[16:11] <ab0oo> Ahh, I'm not smart enough to use unionfs, which I probably ought to figure out
[16:12] <laga> you can "fix" that by editing a file in /etc/modprobe.d/ or something like that
[16:12] <laga> ab0oo: i'm not smart enough either.. give me a few more hours
[16:13] <laga> unionfs on nfs didn't work well here. and aufs (another unionfS) requires a kernel patch. it also won't compile with the hardy kernel. i have had lots of fun lately with that..
[16:14] <ab0oo> what I think I really want is some kind of variable substitution in NFS or "mount", so I can have a single config section that mounts "nfsserver:/export/config-<hostname>" where hostname is dynamically filled in by each host
[16:15] <laga> we're gonna use the MAC address instead of the hostname
[16:16] <laga> (i'm currently working on a as-configless-as-possible approach for diskless clients for mythbuntu, a  HTPC distribution)
[16:17] <ab0oo> I used mythbuntu for a while, then just bought a Buffalo LinkTheater instead.  quieter, cheaper, fits in with the rest of the A/V gear better.
[16:17] <laga> depends on what you need i suppose :)
[16:20] <ab0oo> with autofs, there appears to be a way to do variable substitution to include HOSTNAME, OS, VERSION, etc.
[16:20] <laga> sounds nice
[16:21]  * laga needs to find out how ltsp/edubuntu uses sshfs
[16:51] <LaserJock> ogra: is the seed structure going to change soonish? Will ship-addon go to ship?
[16:51] <o00w> does anyone program with gcc?
[16:52] <LaserJock> depends on the question ;-)
[16:53] <o00w> well I see gcc listed in /usr/bin but it does nothing
[16:54] <o00w> I can launch it from terminal but it expects me to specify the file that I wish to open with gcc
[16:54] <LaserJock> well, gcc is the compiler
[16:54] <LaserJock> you need to write a C program first and then compile it with gcc
[16:54] <o00w> so what would be the gui I would use to write c code?>
[16:55] <LaserJock> well, any text editor would do
[16:55] <o00w> hmmm I was hoping to have something error check on the fly
[16:55] <LaserJock> but if your interested in GUI tools I think anjuta is popular
[16:56] <ab0oo> eclipse with the C extensions does something like that
[16:56] <ab0oo> also has all the syntax highlighting, etc.
[16:56] <LaserJock> yeah, eclipse would be the other one you might try. It's a Java app but has lots of extensions for other languages
[16:57] <o00w> sorry to be such a noob on this but I have seen windows compilers that let u debug and execute the code from within the application u are writing it in
[16:57] <o00w> or maybe it isn't called a compiler
[16:58] <o00w> like quincy
[16:58] <ab0oo> you're not going to find Visual Studio for Linux.  it's just not how Real Programmers program
[16:59] <o00w> well I wasn't looking to be a "Real Programmer" yet.  but is there something that like changes the text color when an int is called and things like that
[16:59] <LaserJock> o00w: there might be some tools like that in anjuta/eclipse
[16:59] <LaserJock> but to be honest, I just use a regular text editor
[17:00] <LaserJock> I don't program much but learning all the little tools takes more time then reading a tutorial/reference and just doing it, for me anyway
[17:00] <o00w> yeah... I haven't even written "hello world" yet so I just thought it would be less frustrating if I could see errors on the fly
[17:01] <o00w> thank you for the input though
[17:01] <LaserJock> well, anjuta/eclipse would at least give you syntax highlighting
[17:01] <LaserJock> and they might have some debugging stuff
[17:01] <LaserJock> you can just try them and see, they're in the repos
[17:53] <Petaris> Hi all
[18:04] <highvoltage> hey Petaris!
[18:07] <Petaris> Hi highvoltage
[18:11] <Petaris> I am having issues when I set X (on the client) to use the amd driver (for the geode2 chipset)
[18:11] <Petaris> basically all ttys come up blank and you can't kill X
[18:11] <Petaris> it does listen to ctrl+alt+del though
[18:12] <Petaris> any other driver dies too
[18:14] <Petaris> *unless I set screen_02=shell
[18:14] <Petaris> then X doesn't launch at all and I can work on the client
[18:28] <Petaris> seems that this issue is referenced here: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amd/+bug/140051
[18:29] <ubotu> Launchpad bug 140051 in xserver-xorg-video-amd "amd driver fails to autoconfigure" [High,Triaged]
[19:39] <Petaris> highvoltage: How can I install a specific version of a package from apt?
[19:39] <Petaris> or list multiple versions?
[19:40] <Petaris> I want to install the new packages listed in that bug report to see if it fixes my issues
[19:44] <Petaris> biab
[20:34] <mgb_> anyone there that could help with a vmplayer error i'm getting running client over ltsp?
[20:34] <johnny> depends
[20:35] <johnny> if it's really related to vmware, then no
[20:35] <johnny> if it's related to ltsp then perhaps
[20:36] <mgb_> ok, i'll try to explain the setup
[20:36] <mgb_> up-to-date edubuntu with two thin clients connected
[20:38] <mgb_> both thin client can execute vmplayer with a range of vm images, however when one client has the windows 2k clone open, the other starts the vm (a unique clone of the w2k vm) and gets an error like XCreateImageFailed signal 11
[20:39] <johnny> what dos w2k have to do with ltsp?
[20:39] <johnny> you mean vmware inside ltsp , not using
[20:39] <johnny> i used vmware/virtualbox to test thinclients :)
[20:39] <johnny> not to run windows :)
[20:40] <johnny> try with say virtualbox?
[20:41] <mgb_> the thin client is using ltsp in order to access vmplayer
[20:41] <mgb_> vmplayer then executes a w2k image - there are other images - w2k is just an example
[20:42] <johnny> hmm...you're prolly gonna have to go deeper
[20:42] <mgb_> does virtualbox have much in the way of cloning like vmware
[20:42] <johnny> to figure it out
[20:42] <johnny> i doubt it matches vmware completely
[20:43] <johnny> i just prefer to use open software
[20:43] <johnny> and virtualbox is good enough
[20:43] <johnny> do you have a similiar problem with any other apps that might try to do something similiar?
[20:43] <johnny> when it comes to spawning extra windows?
[20:44] <mgb_> i haven't tried any other apps. the error comes when the vm window resizes to desktop when starting up
[20:45] <johnny> hmm.. perhaps try to do the same with virtualbox, see if the problem is with vmware itself
[20:45] <mgb_> there is a bug report here https://bugs.launchpad.net/ubuntu/+source/rdesktop/+bug/104332
[20:45] <johnny> just backup some of your images
[20:45] <ubotu> Launchpad bug 104332 in rdesktop "rdesktop crashes when logging in to windows 2000 (or pressing cancel)" [High,Fix released]
[20:46] <mgb_> is the latest edubuntu a gutsy release?
[20:46] <johnny> yes
[20:46] <mgb_> if so why is this bug invalid in gutsy?
[20:46] <johnny> aha.. that bug looks like rdesktop itself had to be patched
[20:46] <johnny> to work
[20:47] <johnny> if so, that'd be similiar for vmware.. if they really were similiar
[20:48] <mgb_> cool. thanks for the help. do you think there are any performance issues with thin clients running multiple vm images over a gig network?
[20:49] <johnny> uhmm.. i don't have any experience with that
[20:49] <johnny> so i won't speculate
[20:49] <mgb_> in terms of the network not being able to cope with the remote display of an X session with multiple vms open
[20:49] <johnny> mine is still 10/100
[20:50] <johnny> some other folks here prolly run such setups tho
[20:50] <johnny> i only have 4 clients on mine atm
[20:54] <mgb_> that's for mentioning virtualbox, it seems easy to clone vm
[20:57] <mgb_> i need a system that allows the use of thin clients in order to access multiple vm images. the vms at the moment are automatically cloned, in a hackish way due to the vmware API not supporting proper cloning yet, in order to provide the users of the thin client with non-persistant vm images where changes only persist if rebooted - if the vm is shutdown the changes are lost. do you think this is achievable with virtualbox?
[21:05] <johnny> who knows
[21:05] <johnny> the point is to test if you get the same issue with
[21:05] <johnny> if you don't, then the issue is with vmware, and you'd have to complain to them
[21:06] <lns> it's probably not of much use to people right now, but I thought I'd share a wiki I started on wikidot.com - the information I'm gathering and putting on it regards UbuntuLTSP/Edubuntu specifically, and has a lot of useful URLs regarding bugtracking, forums/websites, etc... I plan on expanding the site a LOT as times passes, so hopefully it will grow to be pretty extensive. For those of you that want to see it now, check out http://lns.wikidot.com - let me kno
[21:06] <lns> w if you find it useful!
[21:07] <LaserJock> lns: why not use the Ubuntu wiki?
[21:07] <johnny> lns, did you attempt firefox 3 yet?
[21:09] <lns> LaserJock, because the LNS wiki is for tracking issues/subjects directly relating to our own clients
[21:09] <LaserJock> hmm, I see
[21:09] <lns> johnny, no... i don't want to try FF3 until it is released as stable..there are too many people using it right now
[21:09] <lns> LaserJock, there is still a lot of useful information (especially the reference url section) so feel free to duplicate it (or i can, but it's really hard for me to find the right places on the ubuntu wiki)
[21:10] <LaserJock> lns: this all applies to 7.10?
[21:10] <johnny> lns, well it's not like you couldn't just add an icon
[21:10] <johnny> and use it along side
[21:10] <lns> LaserJock, most of it, yes
[21:12] <lns> johnny, i could, but there are many more issues i have to fix/deal with first before trying more beta software..i need to re-try the XRAMPERC solution because I think the list post I followed was wrong for my setup
[21:12] <lns> that's one of the biggest reasons I started my own wiki - to track specific issues and be able to gather all information regarding it in one place
[21:13] <LaserJock> https://help.ubuntu.com/community/EdubuntuFAQ is one place we house stuff
[21:13] <LaserJock> https://help.ubuntu.com/community/EdubuntuRecipes
[21:14] <LaserJock> I think those are the primary wiki pages for Edubuntu help
[21:15] <lns> oo, nice.. thanks LaserJock
[21:15] <lns> I'll put that in my reference urls, already finding stuff in there that relates to issues we're having ;)
[21:15] <LaserJock> cool
[21:16] <LaserJock> seems like we should have a release-specific wiki page for issues that only hit a particular release
[21:16] <lns> LaserJock, yeah...i'm already finding it very hard to keep a solid hierarchy in my OWN wiki... heh
[21:17] <LaserJock> yeah, wiki's can quickly become very messy
[21:18] <LaserJock> hmm, I should see if I can get ltsp set up on my new laptop
[21:18] <lns> I strongly considered implementing my own wiki pages in the ubuntu/edu wikis...but man....it's just so difficult, i need more control over my specific issues
[21:19] <LaserJock> well, if you have clients or need to track your specific stuff it makes sense
[21:20] <LaserJock> but where possible it'd be nice to share since we are always looking for more documentation
[21:20] <lns> LaserJock, exactly
[21:21] <lns> i wish there was some way to link actual page text cross-wiki style (not sure if that's the right wordage)
[21:21] <lns> instead of just a link
[21:21] <LaserJock> right
[21:22] <LaserJock> I think that may be possible, but it wouldn't be feasible for Ubuntu's because I think it requires messing around with the wikis
[21:24] <lns> ahh
[21:26] <lns> well if it's ok i can always put a link to my specific wiki on the Edubuntu/UbuntuLTSP wiki for reference
[21:26] <lns> dunno if that would just clutter things up more, but at least it'd be a link to more info
[21:27] <LaserJock> hmm, I probably be for copying content over
[21:27] <LaserJock> are you gonna license your wiki? I didn't check
[21:37] <lns> LaserJock, license my wiki?
[21:38] <LaserJock> yes, copying content only works if the licenses are compatible :-)
[21:41] <lns> hmm, never thought about that ;)
[21:41] <lns> i guess i could, i have no idea howto thou
[21:43] <LaserJock> you can just add a license statement
[21:43] <lns> like gpl? (sorry i'm a license newb)
[21:44] <lns> can i copy the license statement from somewhere? ;)
[21:44] <LaserJock> https://help.ubuntu.com/community/License
[21:44] <lns> nice
[21:44] <lns> thx
[21:45] <LaserJock> notice that at the bottom of the page (and every other page on help.ubuntu.com/community) there is a link "Legal" and a little badge that says CC By-SA
[21:45] <LaserJock> the CC-By-SA is a common documentation license from Creative Commons
[21:46] <LaserJock> GFDL is also used a fair amount, it's from FSF like GPL
[21:54] <lns> LaserJock, ok cool - here we go: http://lns.wikidot.com/license
[21:54] <lns> i just dunno if i need to reference the ubuntu wiki license page to be able to have copied that info...
[21:55] <LaserJock> it looks nice
[21:56] <lns> cool..just added a ref..we should be good to go ;)
[21:56] <LaserJock> awesome
[21:57] <lns> anyway my wiki really isn't much of anything yet.. i just want to help everyone else out like they've helped me out. i hope it will become much more of a good reference in the future as i have time to gather and place information in it.
[21:59] <LaserJock> sure
