rfbProcessClientProtocolVersion: not a valid RFB client

[Jonas Bark]

Yes, you are right, I had two executables and I choosed the wrong one.

I've had some troubles with the font stuff, but it seems to run so far 
(the server).
No, I did not see the error messages on the Psion, only in the Web Browser.

When I now start the VNC Server and try to connect through my Psion, I 
see those entries in the log file:
Couldn't open RGB_DB '/usr/X11R6/lib/X11/rgb'
xrdb: No such file or directory
xrdb: can't open file '/home/boni/.Xresources'
xsetroot:  unknown color "grey"
Connections: accepted: 192.168.10.105::4887
gnome-terminal: Fatal IO error 104 (Connection reset by peer) on X 
server :1.0.
Fenstermanager-Warnung: Schwerwiegender E/A-Fehler 11 (Resource 
temporarily unavailable) auf Anzeige ;:1+.

With my usual PC I can perfectly connect to the Server.
Anyway, I think, we are very close to the solution.

Thank you for your efforts, Jonas
