SOCKS4 and SOCKS5 Proxy for FTP

See more FTP Examples

Demonstrates how to connect to an FTP server through a SOCKS4 or SOCKS5 proxy. Both SSL/TLS and non-secure FTP communications may use SOCKS4 and SOCKS5 proxies. React Native

import { Ftp2 } from '@chilkat/react-native'

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const ftp = new Ftp2();

  ftp.hostname = 'ftp.example.com';
  ftp.username = 'login';
  ftp.password = 'password';

  // 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:
  ftp.socksHostname = 'www.mysocksproxyserver.com';
  ftp.socksPort = 1080;
  ftp.socksUsername = 'myProxyLogin';
  ftp.socksPassword = 'myProxyPassword';
  // Set the SOCKS version to 4 or 5 based on the version
  // of the SOCKS proxy server:
  ftp.socksVersion = 5;
  // Note: SOCKS4 servers only support usernames without passwords.
  // SOCKS5 servers support full login/password authentication.

  // Connect and login to the FTP server.

  // This step is only necessary if the file is not in the root directory
  // for the FTP account.
