[GLLUG] ssh to administer another computer over the internet

[Athanasius Pelletier]

I am at my parents' house and I want to be able to update and troubleshoot
their computer from my own back in Michigan.  Somebody told me how to do
this a while back but I don't remember how.  I know I need their ip address
and set the router to leave port 22 open (do they call that telnet?)  what
else do I need to do?
