title: How many TCP/IP socket connections can a system(computer) handle?
body: <p>I have been working on a project regarding TCP/IP socket connection and message transferring through these sockets. I am connecting to a UNIX server with a specific IP address and establishing socket connections. So far I could manage roughly 16000 connections from 1 host (in this case this is my own pc). And when I try establishing other connections from other hosts (either it is Mac Osx or Windows PC), I reached the same maximum connection number, 16000. </p>
  
  <p>I can have 65536 connections on server side and I literally maintained that. But only when it is 16000 connections in each of 4 different computers. I wonder why I have this and how I can establish more than 16000 connections from only 1 host. </p>
