I am working on setting up local apps under Edubuntu 7.04 using LTSP 5. My goal is to run firefox locally with flash and java and have working sound. My server is running the 64-bit edition which is giving me some headaches for flash and java, in the end I think it would be best to run those as local apps. I have received some direction from Jim McQuillan and from the website https://wiki.ubuntu.com/Ltsp-Local-Apps. Here is where I am at as of now.
I have set up LDAP on the server and exported /home. I also chrooted into the client directory /opt/ltsp/i386 and installed libpam-ldap, libnss-ldap, libpam-mount, openssh-server, firefox, and flashplugin-nonfree. I configured ldap and am able to confirm users with "id <username>" and "getent passwd <username>". I configured /etc/security/pam_mount.conf with the following line: volume * nfs 10.6.1.155 /home/& /home/& - - - To try and tell pam to mount the users home directory at login. This doesn't seem to be working. So for testing purposes I am just logging in on Screen1 (alt+ctrl+f1) and manually mounting /home with "sudo mount -t nfs 10.6.1.155:/home /home" (my ltsp server is 10.6.1.155). This mounts /home and I can see all users folders. I have set /etc/ssh/ssh_config on the server with "ForwardX11 yes" and configured /opt/ltsp/i386/etc/ssh/sshd_config with "X11Forwarding yes". >From a terminal (with the manually mounted /home from screen1), I can log in >with one of my ldap users, open a terminal and "ssh [EMAIL PROTECTED] (where testuser is the logged in ldap user and 10.6.254.149 is my thin clients current IP) and authenticate with the users password. I get an error of "Warning: No xauth data; using fake authentication data for X11 forwarding", but this error seems trivial as I am still able to use the ssh session. I can issued the command "firefox" from the ssh session and after a long wait (about 30 seconds) I actually get a firefox running as a local app. Once open I am able to navigate websites with a fair amount of speed (about as good as I would expect from a client with 533Mhz and 128MB RAM). So I guess I could call this a step in the right direction and partial success. However the speed to open is a concern, flash runs but still has no sound, and of course I have the issues of pam_mount not automatically mounting the /home directories and I have to manually ssh into the client and run firefox. Anyone have any suggestions for me from this point? I assume that I can figure out how to avoid the manual stuff for ssh and nfs mounting, but I don't understand why this app takes so long to load and why sound isn't working. If I can't get past those 2 issues there really is no reason to move forward with the others. Also I wonder if there is a more efficient way of accessing the local app without using X11 forwarding, it seems like a lot of extra network traffic could be caused by having to send the X data back to the server just so the server can send it back to the client. There must be a way to access it locally.
