[TriLUG] sftp/ssh to boxes behind a firewall

[Michael Rothwell]

You could use ssh as a SOCKS proxy (ssh -D) and then use:
- socks-aware programs (e.g., firefox)
- tsocks ( http://tsocks.sourceforge.net/ ) to access your network's  
internal resources using non-SOCKS-aware programs.
- ssh with the "ProxyCommand" option and a helper, see http:// 
zippo.taiyo.co.jp/~gotoh/ssh/connect.html

You could also run PPP over SSH to give your remote machine an ip  
address on your internal network, when ssh/sftp as normal. This is  
using TCP over TCP, though, so it can be a little shaky.
