Dear all, Thanks for your replies. However I don't know why I didn't received many replies on time. For example today I saw that many replies were sent 2-3 days days ago and now I am reading them!! I think the problem is with mailing list. anyway.... After I turned on the sshd in debug mode (-ddd) and connect from a host, I see this: debug1: session_input_channel_req: session 0 req x11-req debug2: bind port 6010: Cannot assign requested address debug2: bind port 6011: Cannot assign requested address debug2: bind port 6012: Cannot assign requested address debug2: bind port 6013: Cannot assign requested address After some search I found this topic http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=422327 In the last reply, it is stated that 1) Adding the following to your sshd_config AddressFamily inet 2) Restart SSH I did that exactly and now I can forward X. The problem has been solved. hope this help others too // Naderan *Mahmood; ----- Original Message ----- From: Darryl Cook <dlc@xxxxxxxxxxxxxxx> To: Mahmood Naderan <nt_mahmood@xxxxxxxxx> Cc: Sent: Friday, May 27, 2011 7:23 PM Subject: Re: problem with X11Forwarding make sure you enable it in ssh_config as well. that controls your ssh sessions.
