Using ssh to tunnel from server on public wireless

timm · 2010-09-22 14:45:28

I have a server on a public wireless network with an unrouteable address (Remote). (yes, I know this is strange) I don't have any way to access the public router to direct connections to Remote, so any initiation has to come from that machine. I need to connect Remote to my office server (Office) so I can move files back and forth, and ideally, I would like to connect to an application on Remote over the net. The app has a browser interface.

I'm thinking that for at least part of this, I can create an ssh tunnel from Remote to Office. I'd have to set it up to stay alive when dormant, and will also have to have a mechanism for checking if it went down and to re-initiate the tunnel from Remote if that happens.

I've done some simple ssh tunneling for a remote desktop connection between 2 windows machines, but I'm not sure if what I'm proposing here is doable. I'd appreciate any suggestions on how to accomplish this, or alternatives.

I don't have a fully formed plan, but here are my thoughts:

If the system can receive email, then write something that monitors inbound emails for a trigger message, including the address to which to connect.

As to what you are trying to do, google "ssh reverse channel". This site describes what I think you are trying to do: http://www.howtoforge.com/reverse-ssh-tunneling

Ewaller is right, combine that with a bash while loop to bring it back up if the connection drops for some reason.
