Here's another question for the clever people.
I want to check that my SDK server is running and the correct port open, ie is it able to be connected to from the outside.
I know (And I have used in the past) a php script can check and display the status of a service behind open TCP ports.
But I'm stuck checking my server as it's UDP.
I'd like to use PHP to check as I can then host this on a server outside of my LAN and get around any NAT loopback issues.
Has anybody else done this?
Or has anybody any ideas how to do this?
