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.

bool success = false;

Chilkat.Ssh ssh = new Chilkat.Ssh();

//  Connect and authenticate a standalone SSH object.
success = ssh.Connect("ssh.example.com",22);
if (success == false) {
    Debug.WriteLine(ssh.LastErrorText);
    return;
}

//  The SSH password should come from a secure source rather than being hard-coded.
string sshPassword = "mySshPassword";
success = ssh.AuthenticatePw("sshUser",sshPassword);
if (success == false) {
    Debug.WriteLine(ssh.LastErrorText);
    return;
}

Chilkat.Socket socket = new Chilkat.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.
success = socket.UseSsh(ssh);
if (success == false) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

//  Connect to the destination through the SSH tunnel.
bool bTls = false;
int maxWaitMs = 5000;
success = socket.Connect("db.internal",5432,bTls,maxWaitMs);
if (success == false) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

Debug.WriteLine("Connected to the destination through the SSH tunnel.");
