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

See more SSH Tunnel Examples

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. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let _ = false;

let tunnel = chilkat::SshTunnel::new();

let ssh_hostname = "sftp.example.com".to_string();
let ssh_port = 22;

// Connect to an SSH server and establish the SSH tunnel:
if tunnel.connect(&ssh_hostname, ssh_port).is_err() {
    println!("{}", tunnel.last_error_text());
    return;
}

// Authenticate with the SSH server via a login/password
// or with a public key.  
// This example demonstrates SSH password authentication.
if tunnel.authenticate_pw("mySshLogin", "mySshPassword").is_err() {
    println!("{}", tunnel.last_error_text());
    return;
}

// The destination host/port is the database server.
// The DestHostname may be the domain name or 
// IP address (in dotted decimal notation) of the database
// server.
tunnel.set_dest_port(1433);
tunnel.set_dest_hostname("myDbServer.com");

// 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.
let listen_port = 3316;
if tunnel.begin_accepting(listen_port).is_err() {
    println!("{}", tunnel.last_error_text());
    return;
}

// 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:
let wait_for_thread_exit = true;
if tunnel.stop_accepting(wait_for_thread_exit).is_err() {
    println!("{}", tunnel.last_error_text());
    return;
}

// Close the SSH tunnel (would also kick any remaining connected clients).
if tunnel.close_tunnel(wait_for_thread_exit).is_err() {
    println!("{}", tunnel.last_error_text());
    return;
}
