Hi!

I am trying to forward an X-Display from a Sun to a Linux machine (SunOS 5.9 to Open Suse 10.0). Trying to launch an xterm I receive

xterm Xt error: Can't open display:

Setting the Display explicitly just stalls the process.

I already tried to uncomment -nolisten tcp in Xservers and xserverrc without success.

My logfile for the ssh -X -v:

debug1: Authentication succeeded (password).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
debug1: Requesting X11 forwarding with authentication spoofing.
debug1: Sending environment.
debug1: Sending env LANG = en_US.UTF-8

Putting an rc file in my .ssh directory I get the following error messages:

.ssh/rc: Host: not found
.ssh/rc: ForwardX11: not found
.ssh/rc: ForwardAgent: not found

I suspect this might be a compability issue between Solaris ssh and Open ssh? Maybe there is a workaround that I have not seen. The xforwarding from another Sun in our network seems to work.

Any help appreciated! Thanks in advance!

Is the Sun set to allow X forwarding? (look in /etc/ssh/sshd_config or something like that)

Thanks! Changed the option in /etc/ssh/sshd_config from

X11Forwarding no

to

X11Forwarding yes

and it works. I did not realize the problem could be lying on the sending side.

It works both ways. Your ssh talks with sshd on the other machine. If you are on Solaris and ssh back to Linux, you will be talking to the Linux sshd and you also need the same entry in your /etc/ssh/sshd_config on the Linux side.
