SFTP using SOCKS Proxy

See more SFTP Examples

Demonstrates how to connect to an SFTP/SSH server through a SOCKS4 or SOCKS5 proxy. Dart

import 'package:chilkat/chilkat.dart';

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

  final sftp = CkSFtp();

  // To use a SOCKS4 or SOCKS5 proxy, simply set the following
  // properties prior to connecting:
  // The SOCKS hostname may be a domain name or 
  // IP address:
  sftp.socksHostname = 'www.mysocksproxyserver.com';
  sftp.socksPort = 1080;
  sftp.socksUsername = 'myProxyLogin';
  sftp.socksPassword = 'myProxyPassword';

  // Set the SOCKS version to 4 or 5 based on the version
  // of the SOCKS proxy server:
  sftp.socksVersion = 5;

  // Note: SOCKS4 servers only support usernames without passwords.
  // SOCKS5 servers support full login/password authentication.

  // Connect to the SSH server.  
  // The standard SSH port = 22
  // The hostname may be a hostname or IP address.
  final hostname = 'sftp.example.com';
  final port = 22;
  try {
    sftp.connect(hostname, port);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Your application is now connected to an SFTP/SSH server 
  // through a SOCKS4 or SOCKS5 proxy.
