X11 forwarding is only initiated if the DISPLAY variable is set. Try setting DISPLAY to "localhost:0.0", for example, and run 'ssh -v -X user@host' again. You should see this in the log: debug1: RSA authentication accepted by server. debug1: Requesting pty. debug1: Requesting X11 forwarding with authentication spoofing. debug1: fd 3 setting TCP_NODELAY Hope this helps, Igor -- http://cs.nyu.edu/~pechtcha/ |\ _,,,---,,_ [EMAIL PROTECTED] ZZZzz /,`.-'`' -. ;-;;,_ [EMAIL PROTECTED] |,4- ) )-,_. ,\ ( `'-' Igor Pechtchanski '---''(_/--' `-'\_) fL a.k.a JaguaR-R-R-r-r-r-.-.-.
