(See the xhost command - it has to be run in X on > host1.) Ah, no. If you ssh in to the remote host with the -Y option, all the mucking with xhosts is moot, and DISPLAY is handled for you. ssh into a remote box with -Y and run "echo $DISPLAY". You will see that you are getting a display on the local machine, but it is display number ten (or some such). That display is tunneled through SSH to your local machine. Normally X uses a clear protocol, meaning anyone can snoop the data. Furthermore, security is bad enough in native X without disabling it entirely. Tunneling X through SSH handles the problem very nicely. Just use the -Y option: ssh -Y foo -- Charles Curley /"\ ASCII Ribbon Campaign Looking for fine software \ / Respect for open standards and/or writing?
