On versions 3, default X server was XFree86, on versions 4 is X.org. By default on versions 4, X config files differs something, p. ex., not allow remote tcp conections (used by telnet forwarding). If allows it, you can see port 6000/tcp open in your host: fuser -n tcp -v 6000 Also, you can see "-nolisten tcp" on X daemon string: ps -def | grep X 2 possible solutions: Open port 6000, or ssh forwarding. - How open port 6000/tcp? If use gdm (don't know in kdm): Edit /etc/gdm/gdm.conf and puts parameter "DisallowTCP=false" Telnet forwarding must work restarting X system. - ssh forwarding: whith command ssh <host> -X -C Probe it (local user and remote user must be the same?). The -X parameter means 'Tunnel Forwarding', and -C is for compression. Good luck! Cecilio M.
