Hi Chris,

I just checked and I could create tunnels and connect to the VNC server in 
the image through the tunnel.
I also checked the server configuration and didn't find any restriction on 
tunnel creation which would explain the problems you experienced.
One thing I would try is to use instead of localhost in the 
command, because localhost is just a name that can resolve to whatever 
address on the server:

    ssh -L 5901: chrismuller at andreas
