argyle

A basic SOCKS5 server library written for node.js.

Features/Limitations

argyle supports the most basic features of SOCKS and not a whole lot more, namely:

• 'No authentication' auth mode only
• CONNECT commmand only

In the future I may add support for more auth modes and commands, but currently this implementation works well for my main use case (sitting between a local browser and server).

Usage

Example: "Normal" proxy server

var argyle = require('argyle');
 
var server = argyle(8080, '127.0.0.1');
server.on('connected', function(req, dest) {
    req.pipe(dest);
    dest.pipe(req);
});

Example: Throttled proxy server using node-throttled-stream

var argyle = require('argyle'),
    throttle = require('throttled-stream'),
    kbpsUp = 32,
    kbpsDown = 128;
 
var server = argyle(8080, '127.0.0.1');
server.on('connected', function(req, dest) {
    var tReq = throttle(req, kbpsUp * 1024),
        tDest = throttle(dest, kbpsDown * 1024);
    
    dest.once('error', function(err) { req.end(); })
        .on('close', function() { req.end(); });
    
    tReq.on('data', function(chunk) {
        dest.write(chunk);
    });
    tDest.on('data', function(chunk) {
        req.write(chunk);
    });
});

Methods

argyle([port = 8080], [host = 127.0.0.1], [debug = false])

Sets up a new SOCKS server on the specified port and host. If debug is specified, the server will output messages about the status of connections.

Events

'connected'

A new client connected to the server and the socket to their requested destination is now open. Handlers for this event are passed a request socket, corresponding to the client that made the request from the server, and a destination socket, corresponding to the server that they requested to connect to.

Installation

With npm:

npm install argyle
