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. Lua

local chilkat = require("chilkat")

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

local ftp = chilkat.Ftp2.new()

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.socks_hostname = "www.mysocksproxyserver.com"
ftp.socks_port = 1080
ftp.socks_username = "myProxyLogin"
ftp.socks_password = "myProxyPassword"
-- Set the SOCKS version to 4 or 5 based on the version
-- of the SOCKS proxy server:
ftp.socks_version = 5
-- Note: SOCKS4 servers only support usernames without passwords.
-- SOCKS5 servers support full login/password authentication.

-- Connect and login to the FTP server.
local success = ftp:connect()
if not success then
    print(ftp.last_error_text)
    return
end

-- Change to the remote directory where the file is located.
-- This step is only necessary if the file is not in the root directory
-- for the FTP account.
success = ftp:change_remote_dir("junk")
if not success then
    print(ftp.last_error_text)
    return
end

-- Download a file.
local localFilename = "c:/temp/hamlet.xml"
local remoteFilename = "hamlet.xml"

success = ftp:get_file(remoteFilename, localFilename)
if not success then
    print(ftp.last_error_text)
    return
end

success = ftp:disconnect()

print("File Downloaded!")
