title: How to find more information about the file descriptor?
body: <p>I am trying to debug a process that hangs, the output of  strace for the process id has last line :<br>
   <code>recvfrom(9,  &lt;detached ...&gt;</code>
  From this what I understand that the process is waiting on the socket.</p>
  
  <p>But I don't know which or what kind of socket is this. How can I discover more about this ? does the file descriptor 9 will give me more information ? How can I use this file discover to know more about what it is waiting for ? </p>
  
  <p>its a python process, running in linux.</p>
