to setup a reverse ssh connection ssh -R Port#1:localhost:Port#2 "host address"
-R is the option to setup the reverse proxy Port 1: this is the port that you need to ssh to from the host in order to connect back to the machine you initiated the reverse ssh connection Port 2: is the port your connecting to the host to open the tunnel (default 22 for ssh) host address is the host your connecting to. so on the machine you want to connect to you from behind a firewall. ssh -R 1020:localhost:22 [email protected] and on your box your connected to to get back into that machine ssh -p 1020 r...@localhost extra credit: ssh -C -D 1080 -p 1020 r...@loclahost this will setup a socks proxy so you can actually use any program that supports socks proxy as if you were on that actual machine, nice for making changes to routers remotely. happy hunting. -Brad On Mon, Nov 16, 2009 at 3:32 PM, Adrian Crenshaw <[email protected]>wrote: > Hi All, > I'm playing around with making reverse connections out of a NATed of > network.
