Actually the same thing happens on a physical interface. Not showing
up in tcpdump there either. So, not academic.
What's going on in Linux socket code that's keeping the reply from
reaching the client's receive socket? It just dies after sendmsg(),
there are no logs, I can't seem to find any counters anywhere.
Why can't a linux box's server reply to its own link local address?
I guess I can put the client in a site local multicast group and
make the server reply to it and it would work...
