Andre,
        I am not familiar with the j2ssh client but Xsessions can be
denied by either the server or the client.  Since your server
configuration works with other clients, check to see that X11 forwarding
is enabled on the client.

        Hope that helps...

Subject: x11 forwarding problems


Hi,
If I connect to a openssh server (SSH-1.99-OpenSSH_3.8p1, running on 
SuSE Linux 9.1 (i586)) using a openssh client (OpenSSH_3.9p1, OpenSSL 
0.9.7d 17 Mar 2004, running on SuSE Linux 9.2 (i586)), then X11 
forwarding works fine.

But, if I use j2ssh as a ssh client to connect to the same sshd, then I
get the following error in the sshd debug output:

debug1: channel 3: new [X11 connection from 127.0.0.1 port 36470]
channel 3: open failed: connect failed: Connection refused

I've been trying to find what might be the problem for a few days now 
but with no success.
I understand that this is not the place to ask questions about j2ssh.  
But what I would like to know is the following:  In general, is there a 
well known condition, either at the client or server side, which would 
cause such a 'connection refused'?

Thanks,
Andre
