Route Socket Connections through an SSH Object

See more Socket/SSL/TLS Examples

Demonstrates Socket.UseSsh, which configures a socket to route subsequent Connect calls through an already connected and authenticated Ssh object using SSH port forwarding.

Background. After UseSsh, the destination host and port passed to Connect are reached through the SSH tunnel rather than by a direct TCP connection. This is one of several SSH-tunneling approaches the Socket class supports.
