SSH tunnels with both endpoints firewalled?

[avarame]

Hiya,

I’ve got an iMac running panther at home and a linux server at a remote location. Both are behind strict NAT/firewalls. I have no incoming ports available on the iMac. I can get to 22, 53 (dns), and 80 on the server. I run a DNS and web server so I can’t really use 53 or 80 for anything but their intended purposes. I have full root access on both machines, and both have full sshd installs.

Is it possible to set up any kind of tunnel between the two machines, to forward Samba traffic over them? I’d like to use the server as a remote backup host for my iMac, and the iMac as a remote backup host for the server. I’d like to automate the process but I feel a bit nervous about setting up scp to run without a password.

So can I make any kind of tunnel, having only ssh (p22) access into the server?

Thanks!

This just in: I’m a fool. I should have TRIED it before assuming it wouldn’t work. Anyway, I can make ssh tunnels now, yay.
