          Try "telnet 6000" to see if you can get a TCP connection to the X server.

          If the connection works, your problem is probably an X Windows authorization issue.

          If telnet can't connect to that IP/port combination, either your X Server isn't listening for remote connections or you have some sort of network issue. On the server, run "netstat -an | grep 6000". You should see that port open and listening for connections. If not, your X server isn't configured to accept remote connections.
