anyone here has some time for me?
I would like to ask some help
openstep, you wont get it if you don't ask
I am running an LTSP at a high school and now I need to extend it with other servers...
problem is I do not use ldap yet, but I should and this is where my question is
I am trying to install and configure openldap on a test server and do not understand something
when setting up my linux server I gave a name ubuntuLDAP
|02:47||mikkel has joined #ltsp|
ldpa configuration asks my domain name and I do not know what to give
it may sounds strange but.... really
so can anyone help?
|02:49||bobby_C has joined #ltsp|
openstep, ldap setup has nothing to do with ltsp, you may get better directions if you ask in #ubuntu for that
ok, I know, but guessed others also have done a setup like I would like
but thanks I will ask there

has anyone had problems with ltsp in hardy with eee boxes?
can't seem to get the intel graphics drivers to work
vesa drivers give me decent resolution but not full HD
I tried making new xorg.conf with "X -configure" and that settles for vesa
editing the driver manually does not help as the driver fails with drmopen and driscreeninit

in lenny i had a failed install of italc, which i removed, and successfully installed x11vnc. i have now upgraded to lenny-backports and, with a new client image, i have reinstalled x11vnc. i can see it is running on the client, but nmap <clientip> does not display the port. i suspect something in the original abortive italc client install has helped x11vnc to work.
the instructions i followed were these https://wiki.edubuntu.org/InstallX11VncOnLtspClients.
there is no firewall in between.
|05:07||amitz has quit IRC|
i have switched to the console and tried running the command directly: /usr/bin/x11vnc -- -display :7 -loop -passwdfile /etc/x11vncpassword -nossl, and it just keeps cycling with waiting 2000ms

seems to be saying that I must have read permission for the auth file, so i have tried running with -auth /var/run/ldm-xauth-l... etc

no idea whether that is correct or not, but it fails with

i am trying to get x11vnc working on lenny-backports, but following the exact installation that worked under lenny does not work under lenny-backports...
running directly from the console /usr/bin/x11vnc -- -display :7 -loop -passwdfile /etc/x11vncpassword -nossl just keeps cycling every 2000ms
saying that I must have read permission for the auth file
i have tried running with -auth /var/run/ldm-xauth-l... etc, as i believe this is one of the changes is lenny-backports
but it fails with X Error of failed request: BadShmSeg (invalid shared segment parameter)

i now have a working command /usr/bin/x11vnc -display :7 -loop -passwdfile /etc/x11vncpassword -nossl -logfile /var/log/x11vnc -auth /var/run/ldm-xauth-l...
I need to install a kernel module for my client network card. I can probably do it with --late-packages. But I plan to just chroot and run apt-get (suppose to work?)? apt-get doesn't seem to work since it can't configure the module since no apt-utils. Installing apt-utils before hand doesn't have any effect. Any idea?
seemingly the "--" was being refused, although it was working under lenny, and it does indeed seem to require the -auth switch.
|06:26||hanthana_ has joined #ltsp|
Or I can only use --late-packages option of ltsp-build-client?
amitz: can you not just add it in the chroot to /etc/modules ?
Is that the only configuration debconf do when installing module? hmm I'll try but I already delete the image and building from scratch again with --late-packages option turned on :-)

so if i'm right that x11vnc now needs the "-auth /var/run/ldm-xauth-l..." parameter, then i need to determine the name of this authority file, as part of /etc/init.d/x11vnc, but how?

When offering Jaunty ltsp root images and nbd chroot from a hardy tftp-server, the resulting chroot produces boot errors like: Broken pipe Reconnecting and Error Ioctl/1.1a failed bad file descriptor. Any clues?
ronalde: that's "normal"
alkisg: ? ... but after authentication the screen stays black
ronalde: that would be a different problem
|07:35||vvinet has joined #ltsp|
|07:35||gate_keeper__ has quit IRC|
ronalde: see ldm.log or the other log files for any clues...
alkisg: how come you are so sure about the harmlessnes for these errors?
ronalde: well, I've been seeing this in all (=6-7) installations for the past months, and I've heard people saying the same thing here about a dozen of times.
(one of them being one of the ubuntu devs)
|07:38||gate_keeper__ has joined #ltsp|
alisg: thx, i'll try checking for other problems. Right now we reverted back to our hardy chroot, which was the last version without the symptom
alkisg: thx, i'll try checking for other problems. Right now we reverted back to our hardy chroot, which was the last version without the symptom
8.10 also had this error message... something else is your problem
And you're saying that you see ldm fine, but when you log in, the screen stays blank?
Well, I'd try with SCREEN_02=shell and SCREEN_07=ldm in lts.conf,
so that I could (1) see the logs and (2) try ssh'ing to the server...
alkisg: did that
alkisg: we have central syslog enabled; ssh-ing to the server works fine
ronalde: did it show any additional info, like e.g. a warning about changed keys or something? (if you tried it from the SCREEN_02 I mean)
and, what does ldm log say?
alkisg: no, the only extra message in the chroot was something like: SCREEN_01 contains a screen script ...
I would have to reeanble the new chroot to check ldm.log
ronalde, first check ~/.xsession-errors :)
(on the server for the user you try to log in with)
ogra: will do that too, thx

I'm having some trouble with a second server. I can boot from the server that's running DHCP, but when I set next server to another server (that also has all the LTSP packages installed, the client built, etc) I get Trying to load pxelinux.cfg/... and it tries all the paths really slowly.
|08:04||Blinny has joined #ltsp|
I'm on Ubuntu. The current DHCP server is running 8.10, the new server is running 9.04. (I'm trying to upgrade.)
|08:09||mikkel has quit IRC|
toddobryan: try to load those files with a real tftp client
i.e apt-get install tftp-hpa and tftp server and get /path/to/file to see if it takes too long...
from another machine, you mean?
Yeah, of from one server to the other, of from a client
also make sure that you only have one DHCP server running in your network
OK...trying both of those now.
having a second dhcp server running will definately break
I'm pretty sure I don't have a second DHCP server running, at least on the local network.
The client is getting the right IP address. (They're statically set, so I know which client is which.)
Checking on tftp now...
|08:20||ec has joined #ltsp|
OK. On the DHCP server, I installed tftp-hpa and started tftp to the new server.
I get permission denied on every get request.
Is the tftp server running ok?
How would I check?
vmware installed on your server ? (it forcefully pulls in xinetd which isnt supported under ubuntu/debian's default setup)
Nope, no vmware.
tftp us started by inetd
check /etc/inetd.conf for a tftp line
#:BOOT: TFTP service is provided primarily for booting. Most sites
# run this only on machines acting as "boot servers."
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
and inetd is running on the machine ?
|08:25||mikkel has joined #ltsp|
ps ax|grep inetd
sysadmin@200-202-server-1:~$ ps ax|grep inetd
2945 ? Ss 0:00 /usr/sbin/inetd
4889 pts/1 R+ 0:00 grep inetd
ls -l /var/lib/tftpboot
Wow, that's weird.
It's working, now.
My remote session got stuck and I couldn't reconnect, so I rebooted.
I must have not restarted some service when I finished installing.
Any idea which one?
To restart inetd (and tftp along with it): sudo invoke-rc.d openbsd-inetd restart
well, since tftp is run by inetd and you didnt get tftp files its likely inetd
I did try to restart tftp-hpa, but not inetd.
How long does it take to actually feel like you know what you're doing and aren't just trying things and hoping the gods smile on you?
|08:34||artista_frustrad has joined #ltsp|
can take a while, especially with ltsp :)
Thanks for the help. Sorry to bother you with something so simple.
(I would have restarted on principle, but I was busy copying home folder over from the old server.)
|08:36||toddobryan has quit IRC|
ogra, any way (more proper than `chattr`) to have a custom pxelinux.cfg/default persist updates? E.g. some ltsp-conf file to put boot prompt opts in? :)
there was something, have a look at the ltsp-update-kernels code
(its long ago that i have looked at it, but we had a config file that gets sourced)
i know vagrant always wanted to improve it though you have to jump though a bunch of hoops to use it
ogra, alkisg: just pu a fresh jaunty i386 chroot live; logged in as a fresh user. The only processes that are started are: sshd: gast2 [priv] / sshd: gast2@pts/9 / bash -c echo LTSPROCKS; /bin/sh - / /bin/sh -. The screen stays black and displays the wait-cursor. ldm.log diaplays no errors (last lines: Beginning X session. / rc_files: /bin/sh /usr/share/ldm/ldm-script xsession / ldm_spawn: pid = 3827)
|08:43||bobby_C has quit IRC|
alkisg, ogra: actueally ... after waiting a loooong while the desktop shows. What could I check further?
alkisg: dns? you're right, the booted chroot doesn't have /etc/resolv.conf ... the i386-directory on the boot-server does have it . I'll try rebuilding the image
dns isnt needed in a default ltsp setup on ubuntu
is the loopback device up on the server ? is gdm running ? (some apps in the gnome session check for the gdm socket to be available)
