Rcon

Source RCON Protocol implementation in Go.

Protocol Specifications

RCON Protocol described in the valve documentation.

Supported Games

Works for any game using the Source RCON Protocol. Tested on:

• Project Zomboid
• Conan Exiles
• Rust (add +rcon.web 0 to the args when starting the server)
• ARK: Survival Evolved
• Counter-Strike: Global Offensive
• Minecraft
• Palworld
• Factorio (start the server with --rcon-bind/--rcon-port and --rcon-password args)

Open pull request if you have successfully used a package with another game with rcon support and add it to the list.

Install

go get github.com/gorcon/rcon

See Changelog for release details.

Usage

package main

import (
	"fmt"
	"log"

	"github.com/gorcon/rcon"
)

func main() {
	conn, err := rcon.Dial("127.0.0.1:16260", "password")
	if err != nil {
		log.Fatal(err)
	}
	defer conn.Close()

	response, err := conn.Execute("help")
	if err != nil {
		log.Fatal(err)
	}
	
	fmt.Println(response)	
}

With an existing net.Conn

If you wish to initialize a RCON connection with an already initialized net.Conn, you can use the Open function:

package main

import (
	"fmt"
	"log"
	"net"

	"github.com/gorcon/rcon"
)

func main() {
	netConn, err := net.Dial("tcp", "127.0.0.1:16260")
	if err != nil {
		// Failed to open TCP connection to the server.
		log.Fatalf("expected nil got error: %s", err)
	}
	defer netConn.Close()
	
	conn, err := rcon.Open(netConn, "password")
	if err != nil {
		log.Fatal(err)
	}
	defer conn.Close()

	response, err := conn.Execute("help")
	if err != nil {
		log.Fatal(err)
	}
	
	fmt.Println(response)	
}

Requirements

Go 1.15 or higher
