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.

use chilkat();

$success = 0;

$ssh = chilkat::CkSsh->new();

#  Connect and authenticate a standalone SSH object.
$success = $ssh->Connect("ssh.example.com",22);
if ($success == 0) {
    print $ssh->lastErrorText() . "\r\n";
    exit;
}

#  The SSH password should come from a secure source rather than being hard-coded.
$sshPassword = "mySshPassword";
$success = $ssh->AuthenticatePw("sshUser",$sshPassword);
if ($success == 0) {
    print $ssh->lastErrorText() . "\r\n";
    exit;
}

$socket = chilkat::CkSocket->new();

#  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.
$success = $socket->UseSsh($ssh);
if ($success == 0) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

#  Connect to the destination through the SSH tunnel.
$bTls = 0;
$maxWaitMs = 5000;
$success = $socket->Connect("db.internal",5432,$bTls,$maxWaitMs);
if ($success == 0) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

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