I believe that security/expiretable is superfluous nowadays since  
pfctl supports the -T expire directive.

Re: Remote ssh tunnel in background or script?

[Svante Kvarnstrom]

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?
