Can I use ssh to communicate across a firewall?
Yes; you can use TCP forwarding for that, by using its secure TCP forwarding features. You can also tunnel through another open port through the firewall (I’m sure all those system admins love me now 🙂 by running a daemon on the remote side on a port that’s allowed through a firewall, like SSL (port 443). Set up the remote daemon running sshd on port 443: # sshd -p 443 Then, on your local system, open a connection on port 443: $ ssh -p 443 remotehost.example.
