hi there, anyone around tonight
I'm frustrated after hours of GOOGLing
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
it boots up fine and "looks" like it's going to login but never actually gets the desktop
I tried changing the login screen back but it still does the same thing
so I can't figure out what it is
Xwindows is running on the server, checked that
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?
no still using LDM as far as I know... Just changed the login screen graphic for the PXE boot client
so it has the school logo on it
Ah, ok, no idea there
anyone else around that might know something? I really don't want to blow it away and start over
sudo ltsp-update-image ?
just to be sure
ok running that now
what does that do?
it updates the image clients boot from
ok that's what I thought
some setting changes require this image to be updated
which ones requires it though can be crazy to figure out it seems
if I change the IP address of the LTPS server, will I need to run this script again?
the server is running in my house (test/config) but will be moved to the school soon for production (grade school)
Does Centos use NBD or NFS?
ip as in the net interface or the ltsp interface (assuming 2 interface setup)
NFS I believe
I have to run single interface mode
I wish I could run the split mode but the way the network is configured in the school, that won't fly
i dont think youd have to update the image..but if something doesnt work it doesnt hurt to update it
they have 5 and 8-port hubs in the classrooms that these LTSP terminals will share with other computers
so while I would love to isolate the network for these terminals, that won't happen
bummer...that didn't work. I rebooted the PXE client and still having the same thing
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
although i seem to have that with ubntu 10.04
if you enter the wrong ID/Pass you get a different error and then it asks you to login again
it's not doing that
after a few tries it finally logs in
I've tried it 4 times
yeah for me if it still wont login then something is up
ltspuser_39: on the server, do you get a successful authentication attempt at /ver/log/auth.log?
hmm let me look
should you have to update the ssh keys for a login screen change?
there isn't an auth.log
I'm not using SSH
OK, centos is too different to be try to be helpful without actually using it :)
yeah same felling here
that's the frustration I have with the different distributions
in the business world, everyone uses Centos/RH
so that's what I know
Ubuntu is too different
as a volunteer, I have to support this once it's live
can't go with something I don't know really well
anyone else here familiar with LTSP on Fedora/Centos
any of you guys integrate LTSP into AD?
I'm hoping to configure groups in Windows AD that provide access rights to the LTSP server
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"|
Fedora does have 389 for AD, and there's also likewise open... haven't used any of those

hi ppl :)
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?
better fix asap?
do they need the devices/resources that these groups enable access to?
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)
so wondering if are really needed for students, and if with FAT clients things change
in addition I see that don't belong to audio group
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
markit, depends on device permissions -- in some cases a group membership might be needed to access for read either
the rule of thumb is: don't fix what ain't broken ;-)
|12:30||pritesh has joined IRC (firstname.lastname@example.org)|
can anyone help for installing the openthinclient server
|12:34||Phantomas has left IRC (Phantomas!~Phantomas@ubuntu/member/phantomas, Ping timeout: 252 seconds)|
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
pritesh: what is the "openthinclient server"?
alkisg: ah, I see, interesting the grep thing on /dev, but what do you do when you add an user?
do you add a student to the "ubuntu default" groups?
markit: only the groups we want them to have access to :)
So, e.g. sambashare, but not cdrom...
alkisg look this http://openthinclient.org
pritesh: is that related to LTSP at all? Check www.ltsp.org

gvy: you got any working experience with a VIA Technologies, Inc. CN896/VN896/P4M900 [Chrome 9 HC]?
by default, X is not starting at all
knipwim, lemme look in archives...
knipwim, there was a success report last March: http://www.altlinux.org/LTSP/beta (in Russian but ids should be readable)
it's ALT Linux
I'd try to get hold of Xorg.0.log to pass it to the xorg maintainers in charge
nice, there is hope for me yet
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
not sure wrt the driver set though
yeah, i'm downloading the tested icewm now, see what's on there
knipwim: with some via chrome I had to use 'nomodeset', but I don't remember the model
|13:55||khildin has joined IRC (firstname.lastname@example.org)|
well, it's starting with the openchrome driver < 0.3
the ideal way to set resolution is through XRANDR lts.conf options?
|14:04||bobby_C has joined IRC (bobby_Cemail@example.com)|
xrandr is fine, it allows changing the resolution later on
The xorg "preferred mode" is better, as it causes less flicker, but we don't have support for that
And, X_HORZSYNC/vertrefresh are fine too, for setting the max==auto res...

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
PhoenixSTF, network latency added by switches is disregardable
Hyperbyte, That I know, I am more worried on line capacity
Right, you meant having one fiber optic pipe for -all- your servers?
Then my next question is, how much capacity does your fiber optic have?
I think 10Gbps
i know 1 Gbps wont cut it
it would take too long to load every client at the same time
|14:57||Parker955_Away is now known as Parker955|
Fat or thin?
If thin, measure bandwith usage of average use and do the math
If fat, measure bandwith usage at boot and do the math...
How many clients per switch?

a bit of a noob question, xrandr says maximum size 1024x768, is that a video card issue, a driver issue or a cable issue?

It's probably a driver issue, that can't read the monitor EDID info, assuming it does support more than 1024x768
