ltsp remoteapps - run applications on the LTSP server via ssh -X


ltsp [ltsp-options] remoteapps application [parameters] ...
ltsp [ltsp-options] remoteapps [-r register] application ...


Setup passwordless SSH, by ensuring that ~/.ssh/authorized_keys contains one of the public user's SSH keys. Then execute ssh -X server app params. If the user has no SSH keys, a new one is generated. For ltsp remoteapps app to work, /home/username should already be mounted via NFS (on LTSP client boot) or SSHFS (on LTSP user login).


See the ltsp(8) man page for ltsp-options.

-r, --register
Register the specified applications as remoteapps, by creating symlinks in /usr/local/bin/application for each one of them. Since /usr/local/bin usually comes before /usr/bin in $PATH, the remoteapps should be invoked even if the application is selected from the system menu.


The following ltsp.conf parameter can be used to register the MATE applications users-admin (Menu ▸ System ▸ Administration ▸ Users and Groups) and mate-about-me (Menu ▸ System ▸ Preferences ▸ Personal ▸ About Me) as remoteapps:

REMOTEAPPS="users-admin mate-about-me"

That way, LTSP users are able to change their passwords or display names. The password change takes effect immediately, while for the new display name to appear in the LTSP client, the sysadmin must run ltsp initrd and the client needs to be rebooted.
