node-rcon is a simple library for connecting to RCON servers in node.js. It implements the protocol used by Valve's Source and GoldSrc engines, as well as many other game servers.

It was originally created to connect to Minecraft's RCON server.

npm:

$ npm install rcon

See examples/stdio.js for a simple example.

Some games use TCP and some use UDP for their RCON implementation. To tell node-rcon which protocol to use, pass it an options object like so:

var options = {
  tcp: false,       // false for UDP, true for TCP (default true)
  challenge: false  // true to use the challenge protocol (default true)
};
client = new Rcon(host, port, password, options);

Here's a non-exhaustive list of which games use which options:

Source games include CS:S, CS:GO, TF2, etc. GoldSrc games include CS 1.6, TFC, Ricochet (lol), etc.

If there's a game you know uses a certain protocol, feel free to submit a pull request.

Please submit a bug report for any game you try that doesn't work!
