At home, I have Ubuntu Linux 10.04 on a spare laptop and a DSL connection that's always on. What are the steps to securely (very important) share this on the web with like DynDNS or something and port forwarding so that I can access it over port 443 (HTTPS port) over the web and access the GUI of the desktop? My DSL router supports port forwarding.
See, sometimes I'm in a hotel with bad Internet (only ports 80 and 443 available) and need a way to connect to a power user workstation so that I can do emergency systems operations tasks for my employer.
