You might want to look at autossh which will automatically reopen closed tunnels.
Check your linux distribution for packages (Debian has it packaged, as does some
of the BSDs)
Otherwise, get it from here: http://www.harding.motd.ca/autossh/

I am looking to setup a reverse SSH shell. Basically, I want a system (behind a firewall with no open incoming ports) to connect back to my computer and provide a shell on the remote PC for me to use.
Obviously I will need some sort of listener on my side and some method of telling the remote computer to connect back.
Does anyone know of a method to accomplish this - using openSSH or otherwise?
you'd ssh localhost -p 2200 to get back through the tunnel..
If you want to get a little more crazy, you could start playing with ipsec tunnels too, but you need more at the endpoint box then just a ssh daemon.
