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


Hi Jonas,

You are definitely not using a VNC 4.1.1 server computer, I'm afraid.  The
log output you're seeing indicates that you're running a VNC 3 series
server, or something based on that codebase.

The error "not a valid RFB client" was returned by VNC 3 series servers if
the connected "viewer" sent something other than an RFB protocol version
string.  Disabling the protocol check won't help, since the problem is that
the two bits of software are fundamentally speaking a different language.

Incidentally, that's the message you'll get if you direct a web browser to
connect to the RFB port of a VNC 3 series (-based) server - are you sure
you're looking at the error message corresponding to the failed connection
>from the Psion?

Cheers,

Wez @ RealVNC Ltd

Subject: RE: rfbProcessClientProtocolVersion: not a valid RFB client

Well, according to Synpatic I am using 4.1.1 of the RealVNC server which is not the newest version. I tried converting the newest RPM package to a Debian file but install says something with collition with xvncserver, I'm not sure. Connection from a usual Computer VNC client works but not with the Psion. One of the source code from the Psion Java Programs says:
"final String versionMsg = "RFB 003.003\n"
On the Psion, there doesn't exist another VNC Client and this SSH stuff isn't supported. That's why I meant to deactivate the rfbProtocol Check, to force the server/client to accept the connection.

Greets, Jonas

Hi Jonas,

Sorry - I misunderstood your original post. From the log
output below, it
seems that the server software that you are attempting to
connect to is
rejecting the connection because it believes that the
VNC-based viewer you
are using is not using the RFB protocol.

What server software are you attempting to connect to?

Have you tried installing the latest standard VNC server release?

Regards,

Wez @ RealVNC Ltd

Thank you for this answer.
Do you mean display with disable? If so, if I connect
through a Web
Browser from the Psion, it shows "RFB 003.003" to me. But whatever I do, wether through a web browser or a VNC Client it always
says the same:
30/03/07 13:59:45 Got connection from client 192.168.10.105
30/03/07 13:59:45 rfbProcessClientProtocolVersion: not a valid RFB client
30/03/07 13:59:45 Client 192.168.10.105 gone
30/03/07 13:59:45 Statistics:
30/03/07 13:59:45   framebuffer updates 0, rectangles 0, bytes 0

The Psion only supports Java 1.1 but actually it worked great on Windows XP.

Any Ideas left?

Thank you, Jonas
