title: Communication between two computers using an Internet Browser and Sockets?
body: <p>How may I create a socket on my computer that could be reachable from other computers via internet, and work like a web server, maybe using WebSockets?</p>
  
  <p>By the way: could my web server become visible from the Internet and how?</p>

  <p><em>I know I can install a LAMP web server on my computer (my OS is Ubuntu) and use it for a local network.</em><br>
  <em>I know I can use sockets to let 2 computers communicate via internet using their IP addresses (I did it in Java).</em></p>
