not sure, but it may have to do with your firewall settings... Direct (non-tunneled) X connections use the port range 6000+N (where N is the display number, i.e. :0 = 6000, :1 = 6001, ...), so packets destined for these ports need to be routed correctly. Can you establish an X connection through an ssh tunnel? (you probably know that you don't need to / should not set the DISPLAY variable yourself when using ssh to forward X, as it's doing it for you) Erdmut -- Erdmut Pfeifer science+computing gmbh -- Bugs come in through open windows.
