If I use nmap from fnuc (server), it's clearly sees these laptops.
That's actually irrelevant. What matters is whether or not the server can receive packets at that port. Is there anything listening on that port?
I'm assuming avahi-daemon both broadcasts and listens on that port. And avahi-daemon is running on that server, hence it can resolve flap and fmac.
Haha! I'm going to start cackling. Now hilariously, this fnuc Fedora Server was running Fedora 29, upgraded many times, and this was working. But after a clean install of Fedora 30, it's not working and I can't figure out why.
Do you have nss-mdns installed?
Oh my gosh! That's it! For whatever reason avahi-daemon doesn't drag that in. FedoraServer doesn't come with either avahi or nss-mdns and I didn't realize both were required (or more likely, I forgot). As soon as I install it, the server now resolves the mdns names for the two laptops (which already had nss-mdns installed).
Realllly non-obvious!
Thanks!
