When you absolutely, positively have to kill every mother fu need to have X windows access to a remote system, I suggest using SSH. If you can ssh to a host, you can run any X application and have it display on your desktop. A situation where I use this all the time is when I need to run sun console admin on a remote host. You’ll need to make sure that X forwarding is enabled in the remote nodes sshd_config
X11Forwarding Yes
and then connect to that host with a -X flag
ssh -X $USER@$HOST
Done and done. You can run any x program now from firefox to xeyes.
