7 script that sets up a reverse ssh tunnel, and optionally starts a VNC server as well if the START_VNC environment variable is not null
8 PORT is the port that your techy needs access to. In general, for graphical issues use 5900 and for command-line issues use 22
9 REMOTE_PORT is the port that you'll get on the proxy server, any number over 1000 works as long as you and your techy plug in the same number
10 user@proxy is just your username at the remote proxy machine
