oh yeah, i forgot to add the tunnelling part. this is descended from someone
else's post on how to do tunnelling.
on my box, i do, for instance:
ssh -v -f -L 2025:<SMTP_HOST>:25 -N -2 <SMTP_HOST_AGAIN> &
that creates a tunnel to SMTP_HOST. SMTP_HOST and
SMTP_HOST_AGAIN are the same host, of course.
if i connect to port 2025 on my box, the socket connection is automatically
forwarded to my SMTP host's port 25.
you can do the same for any other TCP port. i don't know if UDP
ports work too, i doubt it.
