04:39 | <ltspuser_39> hi there, anyone around tonight
| |
04:39 | I'm frustrated after hours of GOOGLing
| |
04:40 | <Pecker> question is?
| |
04:40 | <ltspuser_39> so I built an LTSP server, and have a client workstation that PXE boots from it. It had been working fine... and then I changed the "login screen" to a different graphic, and now the client can't ever login again
| |
04:40 | it boots up fine and "looks" like it's going to login but never actually gets the desktop
| |
04:41 | I tried changing the login screen back but it still does the same thing
| |
04:41 | so I can't figure out what it is
| |
04:41 | Xwindows is running on the server, checked that
| |
04:42 | <alkisg> What do you mean "changed the login screen to a different graphic"? Are you still using LDM, or did you switch to e.g. GDM?
| |
04:43 | <ltspuser_39> no still using LDM as far as I know... Just changed the login screen graphic for the PXE boot client
| |
04:43 | so it has the school logo on it
| |
04:43 | <alkisg> Which distro/version?
| |
04:43 | <ltspuser_39> Centos 6
| |
04:43 | <alkisg> Ah, ok, no idea there
| |
04:43 | <ltspuser_39> drats
| |
04:44 | anyone else around that might know something? I really don't want to blow it away and start over
| |
04:45 | <Pecker> sudo ltsp-update-image ?
| |
04:45 | just to be sure
| |
04:47 | <ltspuser_39> ok running that now
| |
04:47 | what does that do?
| |
04:47 | <Pecker> it updates the image clients boot from
| |
04:47 | <ltspuser_39> ok that's what I thought
| |
04:47 | <Pecker> some setting changes require this image to be updated
| |
04:48 | <ltspuser_39> ahhhh
| |
04:48 | <Pecker> which ones requires it though can be crazy to figure out it seems
| |
04:48 | <ltspuser_39> if I change the IP address of the LTPS server, will I need to run this script again?
| |
04:48 | the server is running in my house (test/config) but will be moved to the school soon for production (grade school)
| |
04:49 | <alkisg> Does Centos use NBD or NFS?
| |
04:49 | <Pecker> ip as in the net interface or the ltsp interface (assuming 2 interface setup)
| |
04:49 | <ltspuser_39> NFS I believe
| |
04:50 | I have to run single interface mode
| |
04:50 | I wish I could run the split mode but the way the network is configured in the school, that won't fly
| |
04:50 | <Pecker> i dont think youd have to update the image..but if something doesnt work it doesnt hurt to update it
| |
04:50 | <ltspuser_39> they have 5 and 8-port hubs in the classrooms that these LTSP terminals will share with other computers
| |
04:51 | so while I would love to isolate the network for these terminals, that won't happen
| |
04:52 | bummer...that didn't work. I rebooted the PXE client and still having the same thing
| |
04:52 | you sign in with a valid name, it looks like it's going to sign in and then pops back to the login screen again
| |
04:53 | <Pecker> weird
| |
04:53 | although i seem to have that with ubntu 10.04
| |
04:53 | <ltspuser_39> if you enter the wrong ID/Pass you get a different error and then it asks you to login again
| |
04:53 | it's not doing that
| |
04:53 | <Pecker> after a few tries it finally logs in
| |
04:53 | <ltspuser_39> I've tried it 4 times
| |
04:53 | <Pecker> yeah for me if it still wont login then something is up
| |
04:53 | <alkisg> ltspuser_39: on the server, do you get a successful authentication attempt at /ver/log/auth.log?
| |
04:53 | <ltspuser_39> hmm let me look
| |
04:54 | <Pecker> should you have to update the ssh keys for a login screen change?
| |
04:54 | <ltspuser_39> there isn't an auth.log
| |
04:54 | I'm not using SSH
| |
04:55 | <alkisg> OK, centos is too different to be try to be helpful without actually using it :)
| |
04:55 | <Pecker> yeah same felling here
| |
04:55 | <ltspuser_39> rats
| |
04:55 | that's the frustration I have with the different distributions
| |
04:55 | in the business world, everyone uses Centos/RH
| |
04:55 | for servers
| |
04:56 | so that's what I know
| |
04:56 | Ubuntu is too different
| |
04:56 | as a volunteer, I have to support this once it's live
| |
04:56 | can't go with something I don't know really well
| |
04:56 | :*
| |
04:56 | :(
| |
04:57 | anyone else here familiar with LTSP on Fedora/Centos
| |
04:59 | any of you guys integrate LTSP into AD?
| |
05:00 | I'm hoping to configure groups in Windows AD that provide access rights to the LTSP server
| |
05:00 | <alkisg> http://w3techs.com/technologies/history_details/os-linux => here it says debian is first, centos second...
| |
05:01 | * alkisg doesn't care about distros, he was just suddened to hear that "in the business world, everyone uses Centos/RH" | |
05:01 | <Pecker> rofl
| |
05:03 | <alkisg> Fedora does have 389 for AD, and there's also likewise open... haven't used any of those

11:56 | <markit> hi ppl :)
| |
11:57 | hi alkisg :) I've added users so far with adduser and not including them in secondary groups "dialout,cdrom,floppy,plugdev,scanner,lpadmin,sambashare", will it be an issue?
| |
11:57 | better fix asap?
| |
12:06 | <gvy> do they need the devices/resources that these groups enable access to?
| |
12:07 | <alkisg> markit: http://koeritz.org/docs/base-passwd/users-and-groups.html
| |
12:08 | <markit> alkisg: yes, I know they are needed to access resources, but with thin client everythign went ok neverless (i.e. access usb key in teh client)
| |
12:08 | so wondering if are really needed for students, and if with FAT clients things change
| |
12:13 | in addition I see that don't belong to audio group
| |
12:14 | gvy: is needed to access or modify? i.e. without belong to cdrom they can still play a cdrom, as far as I can see... maybe can't burn a cd
| |
12:16 | <gvy> markit, depends on device permissions -- in some cases a group membership might be needed to access for read either
| |
12:17 | the rule of thumb is: don't fix what ain't broken ;-)

| |
12:34 | Phantomas has left IRC (Phantomas!~Phantomas@ubuntu/member/phantomas, Ping timeout: 252 seconds) | |
12:35 | <alkisg> markit: each of those groups is needed for a different thing, you can't have a general answer that covers all of them. E.g. `ls -lha /dev | grep dialout` will show you which devices this group can access directly
| |
12:35 | pritesh: what is the "openthinclient server"?
| |
12:35 | <markit> alkisg: ah, I see, interesting the grep thing on /dev, but what do you do when you add an user?
| |
12:35 | do you add a student to the "ubuntu default" groups?
| |
12:36 | <alkisg> markit: only the groups we want them to have access to :)
| |
12:36 | So, e.g. sambashare, but not cdrom...
| |
12:36 | <markit> oh
| |
12:37 | <pritesh> alkisg look this http://openthinclient.org
| |
12:37 | <alkisg> pritesh: is that related to LTSP at all? Check www.ltsp.org

13:19 | <knipwim> gvy: you got any working experience with a VIA Technologies, Inc. CN896/VN896/P4M900 [Chrome 9 HC]?
| |
13:20 | by default, X is not starting at all
| |
13:20 | <gvy> knipwim, lemme look in archives...
| |
13:23 | knipwim, there was a success report last March: http://www.altlinux.org/LTSP/beta (in Russian but ids should be readable)
| |
13:23 | it's ALT Linux
| |
13:24 | I'd try to get hold of Xorg.0.log to pass it to the xorg maintainers in charge
| |
13:28 | <knipwim> nice, there is hope for me yet
| |
13:34 | <gvy> if you can boot a livecd there here's one using roughly the same codebase: http://ftp.linux.kiev.ua/pub/Linux/ALT/people/mike/iso/mkimage-profiles/live-icewm-20120305-i586.iso
| |
13:34 | not sure wrt the driver set though
| |
13:34 | <knipwim> yeah, i'm downloading the tested icewm now, see what's on there

13:52 | <alkisg> knipwim: with some via chrome I had to use 'nomodeset', but I don't remember the model

| |
14:03 | the ideal way to set resolution is through XRANDR lts.conf options?

14:10 | <alkisg> xrandr is fine, it allows changing the resolution later on
| |
14:10 | The xorg "preferred mode" is better, as it causes less flicker, but we don't have support for that
| |
14:11 | And, X_HORZSYNC/vertrefresh are fine too, for setting the max==auto res...

14:47 | <PhoenixSTF> When you have a network of about 1000 Fat-Clients, is it better to have servers on each switch(s) or just put fiber-optics from the Data-center to the switch
| |
14:49 | <Hyperbyte> PhoenixSTF, network latency added by switches is disregardable
| |
14:49 | <PhoenixSTF> Hyperbyte, That I know, I am more worried on line capacity
| |
14:50 | <Hyperbyte> Right, you meant having one fiber optic pipe for -all- your servers?
| |
14:50 | <PhoenixSTF> Hyperbyte, yes
| |
14:50 | <Hyperbyte> Then my next question is, how much capacity does your fiber optic have?
| |
14:50 | <PhoenixSTF> I think 10Gbps
| |
14:51 | i know 1 Gbps wont cut it
| |
14:51 | it would take too long to load every client at the same time
| |
14:53 | right?
| |
14:57 | Parker955_Away is now known as Parker955 | |
