Creating SSH tunnels...

ssh -L localport:localhost:destport desthost

For example :

ssh -L 9000:romeo:23 julia


firewalls? pah!

-R also creates tunnels

Great for completely subverting any firewalling policy you may be behind. (Not that I am, just that allowing outgoing ssh means that anyone could forward any sort of incoming connections.)

-R is great. I've used to update machines in our DMZ by pointing them to our internal up2date server over an ssh tunnel of that variety.

ssh r00lz
