If I understand your question correctly, simply using ssh to connect to
the remote machine will manage the X traffic (and its authentication) for
you. Otherwise, you'll need to set the DISPLAY environment variable to
inform your X clients of the server they're supposed to use, and you'll
have to make sure your X server allows connections from the remote clients
See the man pages for xhost(1) and xauth(1); the latter is considerably
more secure.
But if you can use ssh, all X traffic is handled automatically and
securely behind the scenes.
If that wasn't your question, let us know... :)
