Open a Forwarded Channel through an SSH Tunnel

See more Socket/SSL/TLS Examples

Demonstrates Socket.SshNewChannel, which opens a port-forwarded channel through an authenticated SSH tunnel to a destination host and port, populating a Socket with the connected channel.

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;
}

// Authenticate the SSH session 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;
}

// Open a port-forwarded channel through the authenticated SSH tunnel to the destination host and
// port, populating a Socket with the connected channel.  Set the 3rd argument to true to establish
// TLS to the destination inside the tunnel.
let b_tls = false;
let max_wait_ms = 20000;
let channel = chilkat::Socket::new();
if socket.ssh_new_channel("db.internal", 5432, b_tls, max_wait_ms, &channel).is_err() {
    println!("{}", socket.last_error_text());
    return;
}

// Use the channel socket to send and receive with the destination through the tunnel.
println!("Forwarded channel opened to the destination.");
