Re: howto port forward w/out remote session?

Sean,

from ssh man:

-N      Do not execute a remote command.  This is useful for just
        forwarding ports (protocol version 2 only).

-f      Requests ssh to go to background just before command execution.
        This is useful if ssh is going to ask for passwords or
        passphrases, but the user wants it in the background.  This
        implies -n.  The recommended way to start X11 programs at a
        remote site is with something like ssh -f host xterm.

Your ssh command then becomes:

ssh -Nf -L 9100:printer:9100 user@gateway



cheers,

c
