| 03:26 | <unimatrix9> hello everyone
| |
| 03:28 | i just visited ltsp website , looks as a very sound solution, but i have one question left open, will it run the 3D windows programs , like for example CAD apps?
| |
| 03:31 | cyberorg has quit IRC | |
| 03:32 | cyberorg has joined #ltsp | |
| 03:40 | <knipwim> unimatrix9: would they run in a normal linux desktop?
| |
| 03:41 | <unimatrix9> windows apps
| |
| 03:41 | <knipwim> the apps you want to run on the ltsp client
| |
| 03:42 | <unimatrix9> i have seen on the site that it can run windows apps, so it would be linux desktops and an windows 3D cad program
| |
| 03:43 | mixed so to speak
| |
| 03:43 | school work spot
| |
| 03:44 | so the setup would be 10 workstations, one server for the ltsp
| |
| 03:44 | clients
| |
| 03:45 | the workstations would run a linux desktop, but should also be able to run windows apps like for example 3D cad,
| |
| 03:46 | is this possible ?
| |
| 03:47 | <knipwim> i don't have any experience with that
| |
| 03:47 | <unimatrix9> okey
| |
| 03:48 | with what do you have experience ?
| |
| 03:48 | <knipwim> i'm working on gentoo integration
| |
| 03:49 | <unimatrix9> ltsp gentoo itegration?
| |
| 03:49 | in
| |
| 03:49 | i see
| |
| 03:50 | then you still have some work to do..
| |
| 03:50 | <knipwim> indeed :)
| |
| 03:53 | <unimatrix9> okey , i will not keep you from your work, have a nice day, and keep up the spirit!
| |

| 04:55 | <alkisg> stgraber, highvoltage: I'm going to create some start/stop etc substitutes to prevent upstart daemons from starting in the chroot while the ltsp client is building
| |
| 04:55 | stgraber, highvoltage: I just tried building a fat client with stgraber's ppa in my sources, and I got this:
| |
| 04:56 | Errors while processing openoffice.org-emailmerge
| |
| 04:56 | E: Sub-process /usr/bin/dpkg returned an error code (1)
| |
| 04:56 | umount: /opt/ltsp/i386/proc: device is busy.
| |
| 04:56 | (In some cases useful info about processes that use
| |
| 04:56 | the device is found by lsof(8) or fuser(1))
| |
| 04:56 | So I'm going to create those substitutes in /var/lib/ltsp, and put them into $PATH before /usr/sbin.
| |
| 05:03 | <highvoltage> alkisg: ok
| |
| 05:03 | <alkisg> Thanks :)
| |
| 05:03 | <highvoltage> alkisg: thanks!
| |
| 05:04 | no thank you, you rock alkisg

| 08:57 | alkisg has joined #ltsp | |
| 09:00 | <knipwim> hmm, common/095-rootpass overwrites the chroot password if it's set earlier in the build process
| |
| 09:01 | rjune has joined #ltsp | |
| 09:01 | <knipwim> errr, it's run always
| |
| 09:06 | i'm not sure what's a good solution for this
| |
| 09:06 | add a mock 095-rootpass for Gentoo
| |
| 09:07 | Kicer86 has quit IRC | |
| 09:08 | <knipwim> giving the common 095-rootpass more options than prompt or not
| |
| 09:13 | <alkisg> knipwim: what options? I was thinking an option to copy the root's password on the server, from the shadow file... :)
| |
| 09:15 | <knipwim> in Gentoo's install, a chroot password is already set before the 095-rootpass script runs
| |
| 09:15 | so, i don't need the server password
| |
| 09:16 | <alkisg> So if you don't set ROOTPASS, doesn't it keep the same password that you set before?
| |
| 09:17 | Ah ok I saw it
| |
| 09:17 | if [ "$ROOTPASS" != "prompt" ]; then
| |
| 09:17 | ==>
| |
| 09:17 | <knipwim> indeed
| |
| 09:17 | <alkisg> if [ -z "$ROOTPASS" ]; then
| |
| 09:17 | If you change it this way, then you could set ROOTPASS="keep"
| |
| 09:20 | Heh, and from what I'm seeing, fedora / opensuse also don't want to set the root password
| |
| 09:21 | Maybe we should move that file to Debian/Ubuntu...
| |
| 09:22 | Selveste1 has joined #ltsp | |
| 09:23 | <knipwim> sounds even better
| |
| 09:24 | in Debian, with a symlink to Ubuntu
| |
| 09:25 | <alkisg> Right
| |
| 09:26 | Altlinux also has its own version... so I don't see any trouble with the change
| |
| 09:28 | <knipwim> should i make commit proposal? or are you commiting it?
| |
| 09:29 | <alkisg> I think you could just go ahead and commit it... since 4 out of 6 distros don't want it in common/, I don't see any point of keeping it there
| |
| 09:29 | If anyone objects, he can just revert the commit.
| |
| 09:31 | <knipwim> can i delete the mock rootpass plugins in Fedora and Suse as well?
| |
| 09:31 | <alkisg> I'm not sure about that, they may want to do it themselves. I don't know... :)
| |
| 09:32 | (they may even want to keep the notes there)
| |
| 09:32 | <knipwim> okay

| 10:23 | <knipwim> another question, is /var/cache/ltsp-localapps used on the client?
| |
| 10:26 | astbis has joined #ltsp | |
| 10:27 | * alkisg changes course about the upstart daemon handling, instead of setting $PATH, dpkg-divert is adviced: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/430224 | |
| 10:28 | <alkisg> stgraber: so opposite of what we've said before, I'm going to try dpkg-divert and see if it works.

| 12:31 | <thskyt> Is there a chanop in here who might be able to help with a bit of a problem?
| |
| 12:37 | <johnny> why do you need a chan op?
| |
| 12:41 | highvoltage has quit IRC | |
| 12:43 | highvoltage has joined #ltsp | |
| 12:45 | <thskyt> johnny: because one of the other guys seems to be muted
| |
| 12:46 | <johnny> everybody is muted who doesn't have a nick registered
| |
| 12:46 | it's not a channel setting, it's a server side setting because of various DOS attacks
| |
| 12:46 | <thskyt> Ahh, thanks for the clarification. :-)
| |
| 12:47 | <johnny> yes.. sadly not our fault
| |
| 12:51 | astbis has left #ltsp | |
| 12:51 | <knipwim> johnny: i've been testing ltsp-update-image
| |
| 12:52 | and it doesn't work out-of-the-box on gentoo
| |
| 12:52 | astbis has joined #ltsp | |
| 12:52 | <knipwim> shouldn't the nbd parts be optional in the ltsp-server package via nbd USE?
| |
| 12:54 | <astbis> test
| |
| 12:54 | <ogra> thats up to the distro .... where its usualy managed via packaging ... which indeed gentoo doesnt use
| |
| 12:58 | <johnny> no.. it won't work without nbd
| |
| 12:58 | <alkisg> How can I use tcpdump to monitor tftp traffic? I can see tcp traffic, but not tftp...
| |
| 12:58 | <johnny> knipwim, sure, you can make ltsp-update-image dependent on the nbd use flag, or .. we could check for nbd inside ltsp-update-image and install it anyways
| |
| 12:58 | and just tell it that you need nbd to use it
| |
| 12:59 | which could go upstream
| |
| 12:59 | that way we don't force a reinstall of the package
| |
| 12:59 | ogra, do you think it would be OK to check for nbd inside ltsp-update-image ?
| |
| 13:00 | <ogra> how would you implement that in a distro independent way ?
| |
| 13:00 | <johnny> look for the nbd device?
| |
| 13:00 | isn't there a way to check for a kernel feature?
| |
| 13:00 | <ogra> you could only use nbd swap
| |
| 13:00 | and have an nfs chroot
| |
| 13:01 | and since ltsp-update-image is also used for creation of fresh images you cant check for existance of an nbd image
| |
| 13:01 | * alkisg brings up the "ltsp configuration file" issue :P :D | |
| 13:01 | astbis has left #ltsp | |
| 13:01 | astbis2 has left #ltsp | |
| 13:01 | <johnny> of course we shouldn't check for an nbd image..
| |
| 13:01 | but isn't there a way to check the running kernel?
| |
| 13:02 | <jammcq> alkisg: i've used tcpdump many times to watch tftp traffic
| |
| 13:02 | tcpdump -i eth0 -s0 port 69
| |
| 13:02 | <alkisg> jammcq: could you tell me the exact parameters? I can't get it right... Thanks!!!
| |
| 13:02 | <knipwim> johnny: my point was to make the nbd parts in the ebuild optional, and dependent on the use flag
| |
| 13:02 | <johnny> knipwim, there would be no need if ltsp-update-image checked for nbd
| |
| 13:03 | <ogra> johnny, you should easily be able to use nbd-client to check for nbd funsctionallity
| |
| 13:03 | <johnny> ah.. that's what we need the flag for
| |
| 13:03 | knipwim, go ahead and add it to the ebuild
| |
| 13:03 | to conditionally pull in nbd-client
| |
| 13:03 | now i remember :)
| |
| 13:04 | <knipwim> i meant the ltsp-server
| |
| 13:04 | there is no easy way for the user to set client use flags
| |
| 13:04 | <johnny> hmm... yes..
| |
| 13:04 | <knipwim> except for some quickstart profile hacking
| |
| 13:04 | <johnny> true.. we could force the kernel to build nbd ..
| |
| 13:04 | yeah.. we should probably sed enable nbd in ltsp-build-client..
| |
| 13:05 | but it doesn't really matter until we switch to dracut

| 13:31 | <astbis> Hi. I have trouble getting my clients to login to the server. Clients boot OK, SSH works, but after login the client returns to the login screen. I got i working for a short while. By changing the default session in gdm on the server, but now it is broken again after just 5 min. Any ideas?
| |
| 13:32 | <alkisg> astbis: check the user's ~/.xsession-errors, and also try disabling compiz for that user
| |
| 13:33 | <astbis> nothing in the .xsession-errors. How to disable compiz?
| |
| 13:34 | I haven't added compiz as far as i know.
| |
| 13:37 | Thanks for the help by the way.
| |
| 13:39 | <alkisg> astbis: one quick way to disable compiz: sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/session/required_components/windowmanager metacity
| |
| 13:40 | <jammcq> alkisg: did you get tcpdump working?
| |
| 13:40 | <alkisg> jammcq: yup, thanks, the problem is that I needed to specify `-i lo` for it to work
| |
| 13:40 | <jammcq> ah
| |
| 13:40 | <alkisg> I didn't realize it until I saw your command :)
| |
| 13:40 | <jammcq> the power of examples :)
| |
| 13:41 | <alkisg> (I was trying with tftp 10.160.31.10 == localhost to see why it wasn't working... it does work now, but I don't know why!)
| |
| 13:41 | <astbis> No change :-(
| |
| 13:42 | <alkisg> astbis: ok. Can you see in /var/log/auth on the server if the session is authorized?
| |
| 13:42 | bobby_C has joined #ltsp | |
| 13:42 | <ogra> check in /var/log/auth.log if you see login attempts for the user at all
| |
| 13:42 | pfft, alkisg beats me :)
| |
| 13:42 | * alkisg types faster :P :D | |
| 13:43 | <astbis> Yes i do. "session opened for user" and "password accepted"
| |
| 13:44 | <alkisg> ogra, can you remember what was the deal with DEBCONF_FRONTEND? Does it help anywhere, or can I just disable it for fat clients?
| |
| 13:45 | astbis: can you also try putting XSERVER=vesa in lts.conf, to verify that it isn't something X related?
| |
| 13:45 | <ogra> it should be set to noninteractve fi you want to do any kind of automated package installs
| |
| 13:46 | <alkisg> ogra, ok, I understand "noninteractive". But why DEBIAN_FRONTEND=passthrough ?
| |
| 13:46 | ...and all the descriptor meddling?
| |
| 13:46 | <ogra> for the CD
| |
| 13:46 | <alkisg> Ah, for progress bar?
| |
| 13:46 | *the
| |
| 13:47 | <ogra> the cd installation runs in several nested chroots
| |
| 13:47 | so you need to do weird descriptor handling ...
| |
| 13:47 | given that i never made it actualy work right you could as well back out to noninteractive though ... but test the CD install if it still works then
| |
| 13:48 | <astbis> It is already VESA. My lts.conf settings worked fine until for a short while ago. But suddenly, without me at the server the clients refused to login.
| |
| 13:48 | <alkisg> ogra: I think it'll solve a few problems with fat clients, so I'll give that a try. Thanks!
| |
| 13:49 | <ogra> you might end up with no progress bar at all in d-i though ...
| |
| 13:50 | pmatulis has joined #ltsp | |
| 13:51 | <alkisg> Hmmm then I could just disable it when the user is (manually) building a fat client..
| |
| 13:51 | <ogra> just set the variable in the fat client plugin ?
| |
| 13:52 | <alkisg> Yeah, something like that... override the value that 010-debconf-frontend sets
| |
| 13:55 | <astbis> Any other ideas. I can't find anything wrong. No error messages. Nothing to go on.
