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.

<?php

use Chilkat2\Socket;
use Chilkat2\Ssh;

$ssh = new Ssh();

// Connect and authenticate a standalone SSH object.
try {
    $ssh->Connect('ssh.example.com', 22);

    // The SSH password should come from a secure source rather than being hard-coded.
    $sshPassword = 'mySshPassword';
    $ssh->AuthenticatePw('sshUser', $sshPassword);

    $socket = new Socket();

    // Route subsequent Connect calls through the already connected and authenticated SSH object.  The
    // destination is reached by SSH port forwarding rather than by a direct TCP connection.
    $socket->UseSsh($ssh);

    // Connect to the destination through the SSH tunnel.
    $bTls = false;
    $maxWaitMs = 5000;
    $socket->Connect('db.internal', 5432, $bTls, $maxWaitMs);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo "Connected to the destination through the SSH tunnel.\n";
