Xclient startup:
$ DISPLAY=:100 xterm
Symptom:
I attempt to connect to the server from the client with the following settings:Mode: SSHEncoding: H.264Quality: AutoSpeed: Autodan at js2 22 : 100
I see on the client:
"starting plink tunnel" flash quickly, followed by "Connection lost"

I see on the server:nothing appears on in stdout on the server

I have verified that I can connect via ssh to dan at js2 using a key that is loaded in pageant.
Any ideas on what could be wrong or how I can debug this further?
