Once I was in a predicament. I was working from home, and I desperately needed to map a drive on my computer to a server at work. Unfortunately, all the computers at work were behind a firewall. However, I had previously convinced the system administrator to poke a small hole in the firewall for SSH connections to the Linux workstation in my office.
So I came up with what I thought was a clever solution. I stopped SMB on my home Linux box, set up an SSH tunnel for the SMB ports to the remote SMB server, and then mapped a drive, through that tunnel, from my home Windows machine to the remove SMB server.
This is the script I ran on my home Linux box:
#!/bin/sh REMOTE_SSH_HOST=___.___.___.___ # fill in IP address here REMOTE_SMB_HOST=___.___.___.___ # fill in IP address here /etc/rc.d/init.d/smb stop ssh -g \ -L 137:$REMOTE_SMB_HOST:137 \ -L 138:$REMOTE_SMB_HOST:138 \ -L 139:$REMOTE_SMB_HOST:139 \ $REMOTE_SSH_HOST /etc/rc.d/init.d/smb start
man ssh for details. It worked like a charm, and the connection was totally secure, even over an insecure internet. Telecommuting's not so bad when you can work like this!
