- Thread-topic: [Fed-Talk] OS X chatting with DNS server via port 5353
If I remember correctly - when dealing with a similar problem I ended up
having to disable the mDNSresponder daemon to get it to stop chattering.
That will nuke all Bonjour/Rendesvous/Zeroconf connectivity though. I
really don't understand why there isn't an option to turn this traffic
off via the GUI.

Send me a pcap (be sure to set the snaplen to 1500 bytes) and I'll be
happy to take a look at it.

Bonjour broadcasts on a backoff & retry schedule in order to query
neighbors about new services. When a Bonjour-enabled service comes
online it similarly broadcasts its presence. Both are done because the
transport is not reliable.
