Re: Proposal to export mdns and llmnr enabled interfaces

[Petr Menšík <pemensik redhat com>]

I have took a look inside into nss-mdns. Its implementation just 
forwards queries name to avahi daemon, but does not send actual packets 
right from plugin. I guess avahi might receive instructions to 
disable/enable interfaces via dbus or more advanced method. It already 
contains ability to exclude or include selected interfaces. But I am not 
sure if it supports modification of that list runtime.

So at least for mdns the proper solution would be in avahi-daemon.
