title: Identify program that connects to a Unix Domain Socket
body: <p>I have a program that is listening to a Unix Domain Socket.</p>
  
  <p>When a client connects to the socket I'd like to find out which program connected and then decide if I allow the connection or not (based on the user/group settings).</p>
  
  <p>Is this possible under Linux, and if so, how?</p>
