rack/tunnel
Automatic port forwading via SSH tunneling.
setup
Be sure to setup your ssh-agent for the SSH connection. If you plan on forwarding a well-known
port (e.g. 80), add GatewayPorts=yes to your sshd_config file (and restart sshd!).
The SSH tunnel will be established on the first request to the rack server.
example
