Minecraft LAN Advertising
While looking for a way to “announce” a Minecraft server to local players, I found this article written 7 years ago. The included Python script works with a couple of tweaks to make it compatible with Python 3:
import socket import time servers = [ ["motd1", 25565], ["motd2", 25566] ] BROADCAST_IP = "255.255.255.255" BROADCAST_PORT = 4445 sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1) print("Broadcasting Minecraft servers to LAN") while True: for server in servers: msg = "[MOTD]%s[/MOTD][AD]%d[/AD]" % (server, server) sock.sendto(msg.encode('UTF-8'), (BROADCAST_IP, BROADCAST_PORT)) time.sleep(1.5)
You only need to change the server array, defined at the top of the file. Save to a file like
broadcast_to_lan.py, and run with
Thanks to kebian for the original script!
