===Menerima Menggunakan python===

Source udp_receiver.py

 import socket
 import time
 
 UDP_IP = "192.168.0.100"
 UDP_PORT = 8888
 
 sock = socket.socket(socket.AF_INET, # Internet
                      socket.SOCK_DGRAM) # UDP
 sock.bind((UDP_IP, UDP_PORT))
 
 while True:
     data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
     print time.strftime('%X %x %Z'), "\n", data
