title: Request time out when pinging server on AWS
body: <p>In order to check the health of a server I have, I want to write a function I can call in order to check whether my service is online.  </p>
  
  <p>I used command prompt to ping the IP address of the server, however all of the packets were lost due to request time outs. </p>
  
  <p>I'm guessing I don't need to have a dedicated function related to handle being pinged, and I believe that it is due to the server security protocols denying the request. Currently the server only allows inbound traffic of HTTP requests, and I believe this to be the problem.</p>
  
  <p>For an AWS instance, what protocol rule do I need to add in order to accept ping requests?</p>
