/*

# This is a simple linux command line utility to execute rcon commands
|
||||
# Just change the YOUR_PASSWORD_HERE to your rcon password (unless
|
||||
# you want to enter it every time) and possibly change the default
|
||||
# IP address from 127.0.0.1 (localhost)
|
||||
#
|
||||
# once downloaded on your linux system, compile it with:
|
||||
#
|
||||
# gcc -o rcon rcon.c
|
||||
#
|
||||
# note, it should work on non-linux too, but may require changing the
|
||||
# socket stuff (i.e. windows will definitely need to add the winsock
|
||||
# initialization line)
