See my answer on serverfault. – joeqwertyDec 8 '09 at 14:45
@joeqwerty, a link to the item on serverfault would be hot.
@intransit, generally speaking, you can find the port number when Wireshark gives a service name, by searching /etc/services (*nix) or %windir%\system32\drivers\etc\services (Windoze). I've seen too many instances where the service name was confusing, but the port number immediately maps to something I know about. – Tommy KnowltonDec 11 '09 at 19:32
It is a protocol running on port 2608/tcp. If you have the MAC address, then you can find the network equipment that generate these packets and infer the use.
