title: How to Identify a Request is coming from same machine?
body: <p>I want to implement an authenticated server to accept request from command prompt also. 
  User can get authenticated token with his username and password.</p>
  
  <p>so problem is when he have that token he can raise further request from any machine with that token. i want to restrict the token for single machine. so any idea how to restrict it?</p>
  
  <p>i have something in my mind       </p>
  
  <ul>
  <li>With IP and Port Number (I hope it is not a suitable solution Because change of IP is easy) </li>
  </ul>
