But, unless this is called a complete tutorial and I'll do all your work mailing list, then I have the firm belief that if he really want to have a working solution then he's also gonna do part of the work.
The guy talks about a solution on a campus. So if he's trying to build such solution then it's a must to be able doing some research on his own. Or at least reading a "old like myself" HOWTO ! I ain't gonna write back what can be found elsewhere (Wiki, Debian Docs, etc) regarding the complete sequence of authentication for using remote display of client for the X11 protocol. > If you're trying to do this without full XDMCP sessions, an easier > approach to running one-off X11 clients remotely would be X11 forwarding > over ssh.
