message asking access for computer ff02::fb
Ever since I downloaded Yosemite, I have been getting a message from Norton Security that computer ff02::fb wants access - what is this?

It's a common mistake made by Norton on a Mac.
It has been screwing up Macs for years, and as the Mac OS gets more and more refined, the chances of Norton actually finding a file dangerous to a Mac is practically nil.
All it's doing it slowing down your Mac, and actually poses a much more dangerous threat that malware or viruses, most of which attack PCs.
Just my 2 cents.
ff02 is the IPv6 multicast scope. The context where I've seen ff02::fb used as a destination is when Apple's AirPort Utility uses MDNS (multicast dns) to locate AirPort Extreme wifi routers on the local network. My client sends a MDNS query to/from UDP port 5353, and the AirPort replies with <broadcasts> to IPv4 224.0.0.251 and to IPv6 ff02::fb.
The only reason I know this is because the AirPort Utility doesn't even try to send the MDNS query if you're connected via Wifi, so Apple proponents repeatedly tell people online to temporarily plug in via Ethernet directly to the Apple device. You know, as if MDNS doesn't work over wifi. It's a bug.
Sorry for the trouble caused. Could you tell us what is the version of Norton program you are running on your Mac? We can help you with this!

Norton Support
Bumping this to see if anyone else has any ideas. I've been having this issue too since the Yosemite update and never had it before.
Going back and forth between thinking this can be related to my Iphone trying to connect to the Mac when they are both on the same WiFi network, but found no real evidence to support this plus my Bluetooth is off (and it needs to be on for them to exchange files, right?).
Thanks Original Poster for putting this issue out there.
I guess Norton Security is the culprit. I click on the "allow" button and the message goes away. I guess some Mac owners don't like Norton because "it slows down the Mac", but I would rather have the extra insurance of internet security it provides. Computers are getting faster, but now that I'm pushing 70, I'm not. ;-)
Well, whatever makes you feel more comfortable. But if you're NOT running Windows on there, ClamX AV works fine, and does not interfere with your OS. Sophos is mor reputable, but will slow down the Mac. IMHO, Norton is PC product. It can really harm / corrupt your hard drive.
Just so you know, I am no spring chicken either.

Hi Bee,
Yup, same everything. Yosemite installed, Norton for Mac installed.
Alternating with the ff02:fb (which is an IPV6 address I believe) I get a message with an IP that looks like its connected to my network (but apart from the above mentioned Iphone nothing else is connected to my modem).
Thanks!
Hi again Bee,
BTW on my first web search on this subject I found another tread mentioning this ff02:fb requesting access issue but in that thread the users where using Little Snitch (no answers there to point me on the right direction to know what is requesting access and to what).
I know Norton is probably overkill (or kill depending on the point of view) on a Mac but I feel better knowing I get to OK what communicates with my computer (would feel better still if I could actually understand what it was).
Norton is far from perfection (maybe the badly resolved IP is a Norton problem, and I can't access this particular modem to see what IP my Iphone is taking when it is on this WiFi) but it makes me feel better to have it on, psychologically soothing tools.
Thanks for your interest and information sharing.

I respect your opinion on this, the same as you have mine.
If you ever decide that your Mac is really having problems, or terribly slow, think of Norton.
We'll always be here to help you get rid of it safely.
Or anything else you need help with ("with which you might need help")
Hope you'll hang around here. Lots of great info here, and it's totally FREE!

Norton is well known in the Mac community for doing real damage to Macs. Instead of protecting the user from danger, it can actually create real havoc in your HD. That is what I meant. You might want to search for "Norton problems on Macs."
House -
What issues are you having that are the same as the OP's?
Do you also have Norton Security on your Mac?
so you said it is a mistake by Norton, but can you explain what the mistake Norton made please?
i am using version 5.7 (43)
this looks to me more like a false alert than anything else....
