How do you check to see if a specific computer port has been blocked? I get a message to check when trying to sync with Apple TV generation 1; running Lion

Running Lion 10.7.4; using Apple TV generation one. When attempting to sync, get message saying to check and see if the iTune port is blocked. Question: How do I check a specific port to see if it is open?

You don't need to, just check your firewall settings and ensure that access is allowed to iTunes.


Are you running any other security software on your Mac.
