x-forwarding with ssh

[Nick Wright]

Hi there.

Currently when I try to run X apps via an ssh login I get the error message

  xterm Xt error: Can't open display: 

Is this a problem with ssh and my x-forwarding?
if so, how do you change the x-forwarding options in ssh?
if not, what is the problem and how do I fix it? :)


thanks,
Nick.
