Open an SSH Tunnel

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.

let socket = chilkat::Socket::new();

// Connect to the SSH server and initialize an SSH tunneling session.  Port 22 is conventional but
// not required.
if socket.ssh_open_tunnel("ssh.example.com", 22).is_err() {
    println!("{}", socket.last_error_text());
    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.
let ssh_password = "mySshPassword".to_string();
if socket.ssh_authenticate_pw("sshUser", &ssh_password).is_err() {
    println!("{}", socket.last_error_text());
    return;

println!("SSH tunnel established and authenticated.");
