I'd stick with ssh. However, if your really worried about having a port
open, I recently ran into a very cool program that actually only opens a
port when you know the correct sequence.

For example, if I wanted to ssh into your box I'd first have to probe
port 1009, 5123, 2213 (in that order) at which time that machine would
automatically add me to the approved list for ssh in the firewall.

It's like a combination lock. =)
