At some point hitherto, plussier at mindspring.com hath spake thusly:

Two.

Yes, you do. Unfortunately, ssh ties up a terminal whenever you do a
port redirection; i.e. you must log into the system to do this. It's
possible for the ssh session to not run any command with the -N
option, but this still ties up a terminal (it just sits there, as if
some program were running in the foreground, producing no output --
because that's exactly what's happening).
