Open an SSH Tunnel
See more Socket/SSL/TLS Examples
Demonstrates Socket.SshOpenTunnel, which connects to an SSH server and initializes an SSH tunneling session, then authenticates it.
Background. An SSH tunnel lets a socket reach a destination host through an SSH server using port forwarding. The sequence is: open the tunnel, authenticate, then open forwarded channels to destinations.
