Hi Joanne,

$ grep -i 5353 /etc/services
mdns            5353/tcp                # Multicast DNS
mdns            5353/udp                # Multicast DNS

Makes more sense.

Interesting.  M$'s list of official ports does not
list it:

I have been working on a PCI (credit card security) probe
of a customer's site all day.  I keep mixing up my ports
with their's.   (When you probe the entire network, you get your own
IP as well as their's and everyone else on the network.) 
AAAAAAHHHHHHHH!!!!

Apparently "lysdexic" is catching.  Now the point I really
wanted to make was, was, was...  Oh phooey, I forgot.  :')

Who are you again?  Are you still in the Navy?   :-D
