o11c / tmwa-finger

Created October 17, 2013 20:32

This is a script to check if a TMW server is alive. By default, it checks the main server, but it takes 2 optional arguments: the hostname and the port. You can finger the login server and the char server, but not the map server. For example, $ tmwa-finger caliban.homeip.net $ tmwa-finger server.themanaworld.org 6902 $ tmwa-finger server.themana…

	#!/bin/bash -e
	SERVER=${1:-server.themanaworld.org}
	PORT=${2:-6901}
	die() {
	echo "$1" >&2
	exit 1
	}

	readbyte() {
	local byte REPLY
