Hello
Have you tried -f (for background) and -N for "Do not execute a remote
command"? See man 1 ssh for more details.

Greetings!
I have a client who recently dropped static IP service in
favor of a "cheaper" solution, so they're now on a DHCP network
blocking port 25, etc.
In order to continue to allow them to connect to an outbound
SMTP box on the LAN, I've done this on their server:
sudo ssh -L thisbox:24:remotebox:52525 m...@remotebox
I've got Sendmail listening there on 52525, and it works
fine; the local clients are told to connect to "thisbox"
port 24. The only issue is that I have to run it from
a terminal session. When I tried to bg the process ("cmdstring &")
it doesn't work, exactly. I've gotten an error message
at times*, and at other times I apparently get "thisbox"
listening on port 24 but it's not an SMTP daemon that's
listening.
I have a feeling it's cause I'm in csh, which is notorious
for backgrounding issues. <?> At any rate, what I'd
like to do is have a script set up the connection, or
write some daemon that would monitor the connection and
fix it if it gets reset. At any rate, if I could get this
SSH process to detach from a terminal, it'd be great.
Any suggestions?

* I'm sorry, but I can't reproduce the error message
this morning. IIRC, something to the effect of
"I can't do nothing, give me a command please?"
