"Well Known" TCP and UDP ports used by Apple

"Well Known" TCP and UDP ports used by Apple software products:

It's a good idea to know what's coming in and going out of your computer. Here is a handy list of ports and protocols that Apple software uses, just to keep you from freaking out when you see all sorts of weird connections on your log. Also, if your firewall is blocking this stuff and you're missing features (like Bonjour recognizing other Macs, you need to unblock the appropriate ports for your network.

"File type not supported" iPod syncing errors

Apple - Support - Discussions - File type not supported

A bizarre problem recently popped up after I had updated to iTunes 7.2. Suddenly, certain songs would no longer sync with the iPod, even though I had ripped them from my own CDs. These weren't iTMS purchases. And there were only 4 mp3s out of a library of nearly 4K songs that wouldn't sync over anymore.

The solution was simple (but stupid on Apple's part):

In iTunes, drag the songs to the desktop.
Then delete them from iTunes.
Re-add the files back in to iTunes.

No clue why this happened.
