It said:
ssh: connect to host 192.168.0.6 port 22: Connection refused

Not much to go on. But then I tried it about an hour later and it 
worked. So I must have changed something, but I'm not sure what. It does 
help to know that internal IP addresses aren't affected by the router 
settings, so I could ignore that piece.

I'll bookmark this. They say that it doesn't work yet with Intel Macs, 
which is what I'd want to use, but they are working on it. I can put it 
on my Powerbook though. As for compiling -- lightweight or no -- you 
have to remember you are talking to a command line idiot here. (But I do 
know about five words in Unix now. ;))

My eventual goal is to get VNC working via ssh, so I can help my mother 
with her computer. For anyone who is following my stumbling around, I'm 
trying to implement this trick:

I need to use reverse port mapping because my mom is behind a firewall 
that neither of us can control. I think I'm about 2/3 of the way there 
now. I made the self-running Terminal file and it seems to work (except 
for the warning I get once in a while that "checking getaddrinfo failed" 
and that I am a possible breakin attempt.)

Thanks for being willing to help while I muddle through this.
