title: How to find out which Node.js pid is running on which port
body: <p>I'd like to restart one of many Node.js processes I have running on my server. If I run <code>ps ax | grep node</code> I get a list of all my Node proccesses but it doesn't tell me which port they're on. How do I kill the one running on port 3000 (for instance). What is a good way to manage multiple Node processes?</p>
