I went through the procedure at
http://computingplugs.com/index.php/Installing_X11 to install VNC, and that seemed to go OK.
However, when I try and connect thru an SSH tunnel, the connection is not working.
I am using Putty on my windows box, with the SSH tunnel set for 127.0.0.1:5901. When I plug "127.0.0.1:1" into UltraVNC viewer, I get a message about "Connection failed: error reading protocol version".
I have tried both the UltraVNC and TightVNC viewers.
What am I doing wrong?
