Questions[ltsp](ubuntu)

On Ubuntu 12.04 I have some kind of problem with LTSP and LDAP. Sometimes I can log to the server, but sometimes I can't (window freezes on LDM) log in from the thin client. Everything is OK when I log to the server like the local machine, but I have some kind of problem on thin client.

pam_mkhomedir.so creates home directory, but I can't log in because nothing happened - ldm freezes. This problem doesn't exist for "local" users (unix accounts) and on first logged LDAP user. It's important to mention that in log I can see nothing special.

Does anybody have a problem with ltsp + ldap on ubuntu 12.04? There wasn't any problem on the previous versions.

When LDM freezes, I get the following in the logs:

May 17 11:59:52 bar sshd[6066]: Accepted password for student2 from 192.168.100.22 port 44000 ssh2
May 17 11:59:52 bar sshd[6066]: pam_unix(sshd:session): session opened for user student2 by (uid=0)
May 17 12:00:03 bar sshd[6315]: subsystem request for sftp by user student2

And nothing else appears for this user.

can i use an Ubuntu 11.10 for netboot over PXE? im aware of the LTSP and other similar proyects, but i dont find information using ubuntu 11.10 (the latest)

I'm running Ubuntu 10.04 64bit Desktop on my server with LTSP5.2 and 10 workstations.

Everytime I put a CD or USB disk into the server it shows up with an error on all the workstations saying 'Unable to Mount '

Is there a way to stop these messages from showing on thin clients?

I'm trying to setup blackberry sync'ing with Evolution on a LTSP client. It works on the server.

I'm using Ubuntu 10.04 64bit on the server and here are the instructions I've followed to get the server working:

1. Install required syncing packages

    $ sudo apt-get install libopensync0 multisync-tools libbarry0 opensync-plugin-evolution opensync-plugin-barry
    $ msynctool --addgroup BB
    $ msynctool --addmember BB barry-sync
    $ msynctool --addmember BB evo2-sync
    $ msynctool --showgroup BB

1. Find PIN number on phone and entered it in to the config

   $ msynctool --configure BB 1

1. Syncing

   $ msynctool --sync BB

This all works but it's no good as the user logs into their thin client not the server.

Running the same steps on the client I get the error: : Synchronizing group "BBtofile" : Unable to connect : Error while synchronizing: Unable to open fifo

At first I thought this would be a USB issue, as I was plugging the device into the client and using a server side program. So I installed the following into my thin client image, rebuilt it and rebooted the client:

$ sudo apt-get install libopensync0 multisync-tools libbarry0 
opensync-plugin-evolution opensync-plugin-barry barry-util multisync0.90

On the client after reboot I tried the following command

$ ltsp-localapps xterm

within xterm

$ msynctool --sync BB

I get the same error!

So I tried btool

$ btool -M

btool displays ContactLdif Mapping information from the blackberry, so it's seeing the device.

If I unplug the device and type btool -M it tells me 'No device found'

Here are the two debug logs I get when trying to sync on the client:

So I'm close but I don't know why I cannot get the sync working.

How can I create a bootable CD to run on an old PC accessing an LTSP server. I have found ample documentation on installing an LTSP server, but no reference on how to create a bootable CD. (PC emulating a thinclient). My old PC does not support booting from LAN.

Thank you.
