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. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

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

    const ftp = try chilkat.Ftp2.init();
    defer ftp.deinit();

    ftp.setHostname("ftp.example.com");
    ftp.setUsername("login");
    ftp.setPassword("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.setSocksHostname("www.mysocksproxyserver.com");
    ftp.setSocksPort(1080);
    ftp.setSocksUsername("myProxyLogin");
    ftp.setSocksPassword("myProxyPassword");
    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    ftp.setSocksVersion(5);
    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.

    // Connect and login to the FTP server.
