I have 2 Ubuntu Dapper machines at home. One is going to a college dorm with may daughter in a couple weeks. I can get her desktop on my computer through VNC here at home. It’s using port 5900.
Is there a way to know whether I’ll be able to reach her machine through this port when she’s at college? I have no idea how they manage their network – nor do I care to ask! On a quick look, I could not find how to get her VNC server to listen to a different port – or maybe this is done through ssh?
