title: How do I ping a server port with iOS 5 SDK
body: <p>Basically, I want to check to see if a game server is online/offline but the server is hosted through a port, how would I go about pinging it to check this. For testing purposes the server I want to ping is <code>fr7.mooshroom.net:25667</code>, however eventually I will be importing the server IP and port from an online plist so could the ip address and port be separated</p>
  
  <p>If you could give me a step by step guide on how to do this, that would be much appreciated.</p>
  
  <p>I am using the <code>Reachability</code> by <code>tonymillion</code> because the apple one doesnt work with iOS 5.</p>
