VNC problems

[John Aldrich]

I have asked on the VNC list and gotten deafening silence. I'm trying  
to use PuTTY on the Windows side of things to create an SSH tunnel for  
VNC. I've gotten PuTTY (and another SSH client) to connect to the  
linux box, but I can't seem to get VNC to connect.

One of the SSH clients I'm using has given me a cryptic error message:
"Server rejected our attempt to open a client-side client-2-server  
connection - reason: SSH_OPEN_ADMINISTRATIVELY_PROHIBITED,  
description: open failed."

This would seem to indicate that SSH is blocking the VNC service that  
I am attempting to connect to. I know that VNC is running because I  
can telnet to localhost port 5901 on the linux box and I get the VNC  
prompt, but when I try from the windows side, I don't get anything,  
which would appear to indicate that the tunnel isn't working  
correctly, but I followed the instructions I've used previously which  
worked fine.

I don't know if it's something I've added since I last used PuTTY to  
tunnel my VNC session or what.

Any ideas???
