(C#) SSH Tunnel for Database Connection (such as ADO, ODBC, JDBC, etc.)

Demonstrates how to create an SSH tunneling client in a background thread of your application. This makes it possible to SSH tunnel database connections without the need for separate software (such as PuTTY) to be running.

//  or with a public key.
//  This example demonstrates SSH password authentication.

//  The DestHostname may be the domain name or
//  IP address (in dotted decimal notation) of the database
//  server.

//  Start accepting connections in a background thread.
//  The SSH tunnels are autonomously run in a background
//  thread.  There is one background thread for accepting
//  connections, and another for managing the tunnel pool.
int listenPort = 3316;

if (success != true) {

//  At this point the app may connect to the database server through
//  the SSH tunnel.  The database connection string would
//  use "localhost" for the hostname and 3316 for the port.
//  We're not going to show the database coding here,
//  because it can vary depending on the API you're using
//  (ADO, ODBC, OLE DB, etc. )

//  This is where the application's database code would go...

//  Stop the background listen/accept thread:
bool waitForThreadExit = true;
success = tunnel.StopAccepting(waitForThreadExit);
if (success != true) {
    Console.WriteLine(tunnel.LastErrorText);
    return;
}

//  Close the SSH tunnel (would also kick any remaining connected clients).
