Re: [Fed-Talk] OS X chatting with DNS server via port 5353

Yes, I use another program but this issue I'm looking at is not straight Bonjour, it's using port 5353 to send something to the DNS servers not broadcast addresses.

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

The services advertised only account for about half of the traffic, if I have iTunes configured with sharing off why should it be broadcasting Bonjour traffic, it does not have any services it's advertising and it's not looking for any advertised services.

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.
