say I have a reverse tunnel from my computer to my shell account online. Does that make me more susceptible to being hacked?

I want to use it for my macbook pro from my dorm room. Cheers

I'm not sure what you mean by "a reverse tunnel from my computer to my shell account online". The usual way to connect from a macbook to a shell account is to simply open Terminal and type "ssh othermachine". This is not, strictly speaking, an ssh tunnel (either forward or reverse). Are you setting up a tunnel so that your shell account can access files or other resources on your macbook? – Doug Harris Jan 7 '10 at 17:12

It might make you more susceptible to attacks from that server. It all depends on how you have the reverse tunnel set up. It is not usually any less secure than a regular ssh tunnel, but it does give the other computer a little more access to your home PC.

Right. Expanding a bit on what Joshua said... this will do nothing to enhance or diminish the risk of being hacked from other sources. If your macbook is on a shared wifi connection in your dorm and you have ports open, those are just as vulnerable as you were before you initiate your ssh connection. – Doug Harris Jan 7 '10 at 17:10
