Hello and thanks for your advice.
Nr. 1 didn't do it, same outcome.
When telnetting into localhost, Port 5901, telnet seems to start up
(just the same as vncviewer) and is then shutting down again -
connection to host lost. I think I'll have to fiddle around with that
sshd again, though I am quite sure, that it's configured alright. So
there may be a bug with the scripts in the SuSE-rpm of OpenSSH 2.9p1-17.
I'll try to compile it from scratch next week.
Has anybody encountered the same behaviour and already found a solution?
Regards,
Markus

via SSH
Markus:
Hello! Try this:
1. Turn off SSH compression (the -C switch). Better/same/worse?
2. Instead of connecting with the vncviewer, telnet into
localhost:5901. Does it connect to an "RFB" prompt?
3. What version of viewer are you using? Might want to try
the Tridia or the TightVNC ones as alternatives.
Good luck!
