They're needed only by a DNS/DHCP server.
I don't think so.
Google combinations of "udp port 5353" "zeroconf rfc" "zeroconf"
"bonjour" and "rendezvous."
I have it open, but then I see the occasional Mac. I don't think Linux
(yet) actively uses it; Windows XP does not, unless one downloads some
software from Apple.
I think Windows addresses the same sorts of problems with uPnP.
It appears that the stimulus for this is my daughters Apple Mac which
sends 224.0.0.251 and my computer tries to respond on port 5353. Her
computer runs dhcp connecting directly via an ethernet cable to the
wireless router since it is on her desk.
I guess then the question is if I open 5353 will she have access to my
DNS? Is this an indication that her computer needs that access? Would
it benefit?
It's simple enough to try it but I still wont know if it accomplishes
anything.
I would think she must have access to the DNS server provided by
Wildblue but it's been a year and a half since we set that one up and I
don't recall what was done and I am lost whenever I use her Mac ...
