I can’t however get FreeNX to reliably proxy to a TightVNC server on our Windows XP laptop. It pretty much always times out.
cat /home/Marc/.nx/T-C-tbird-1003-309AA9190583314C6E14CADAD449AFBC/session Info: Proxy running in server mode with pid '15932'. Info: Waiting for connection from '127.0.0.1' on port '5003'.
