title: Ping Server and Ping Client (UDP)
body: <p>I am studying ping server and ping clients using UDP and I found java codes on line. <a href="http://www.daimi.au.dk/~carl/Uge6/PingClient.java" rel="nofollow">http://www.daimi.au.dk/~carl/Uge6/PingClient.java</a>
  I run it using eclipse and it requires 3 arguments. What are those arguments and where should they be placed? I think the port number and the IP address are arguments but whenever I try to place them in <code>args[0], args[1]</code>, the code is still not running.</p>
  
  <p>Thank you very much!</p>
