dns-service-discovery nmap script

I just posted a new Nmap script that uses the DNS Service Discovery protocol to enumerate information from a remote host. The script queries the Multicast DNS Service/Bonjour/ZeroConf for a list of services and then queries each service for additional information. The results are decoded and presented in a list similar to the one below. Systems that are known to ship with this service active include Apple OS X, Ubuntu and many printers.

The script is available over at the Nmap script page and should be run like this:

Here’s some sample output:

5353/udp open zeroconf
