title: Multiple connections on the same port socket C++
body: <p>I need to accept multiple connections to the same port.
  I'm using socket in C++, i want to do something like the SSH do.
  I can do an ssh user@machine "ls -lathrR /" and run another command to the same machine, even if the first one still running.</p>
  
  <p>How can i do that?</p>
  
  <p>Thanks.</p>
