Finding services advertised with Bonjour via Flame

Have you ever had an issue with someone sharing an iTunes library, and you want to quickly track down the IP of the offending user?

Here is a quick little guide on getting that done.

dns-sd is a service discovery application that can make tracking down users sharing various information quite easily. It also has a great API for accessing various information about local DNS information, and setting local DNS advertising quite easily.

…and by a minute, I meant more like an hour. I commented most of the material, and the source can also be found at

A lot more went into this than initially expected, but that is always the case when it comes to bash.
