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.

    //  not required.
    success = CkSocket_SshOpenTunnel(socket,"ssh.example.com",22);

        CkSocket_Dispose(socket);
        return;

    //  After the tunnel is open, authenticate before opening forwarded channels.
    //  The SSH password should come from a secure source rather than being hard-coded.
