Socket/SSL/TLS through SOCKS5 / SOCKS4 Proxy

See more Socket/SSL/TLS Examples

Demonstrates how to use the Chilkat Socket/SSL/TLS component/library with a SOCKS5 or SOCKS4 proxy server. Lua

local chilkat = require("chilkat")

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

local socket = chilkat.Socket.new()

-- To use a SOCKS4 or SOCKS5 proxy, simply set the following
-- properties prior to calling Connect.  The connection may be SSL/TLS or
-- non-secure - both will work with a SOCKS proxy.
-- The SOCKS hostname may be a domain name or
-- IP address:
socket.socks_hostname = "www.mysocksproxyserver.com"
socket.socks_port = 1080
socket.socks_username = "myProxyLogin"
socket.socks_password = "myProxyPassword"
-- Set the SOCKS version to 4 or 5 based on the version
-- of the SOCKS proxy server:
socket.socks_version = 5
-- Note: SOCKS4 servers only support usernames without passwords.
-- SOCKS5 servers support full login/password authentication.

-- Connect to port 5555 of 192.168.1.108.
-- hostname may be a domain name or IP address.
local hostname = "192.168.1.108"
local ssl = false
local maxWaitMillisec = 20000
local success = socket:connect(hostname, 5555, ssl, maxWaitMillisec)
if not success then
    print(socket.last_error_text)
    return
end

-- Set maximum timeouts for reading an writing (in millisec)
socket.max_read_idle_ms = 10000
socket.max_send_idle_ms = 10000

-- The server (in this example) is going to send a "Hello World!"
-- message.  Read it:
local receivedMsg = socket:receive_string()
if not socket.last_method_success then
    print(socket.last_error_text)
    return
end

-- Close the connection with the server
-- Wait a max of 20 seconds (20000 millsec)
success = socket:close(20000)

print(receivedMsg)
