Quoting Didier Kryn (k...@in2p3.fr):
Avahi daemon is the Linux dnssd service. dnssd is a protocol
for service discovery on LAN (formerly known as Apple "Bonjour").
The essential utility for me is to allow to discover CUPS servers on
the LAN, because recent versions of CUPS advertise their presence by
the dnssd protocol instead of the former ad hoc protocol.
dnssd is the most annoyingly and pointlessly chatty network protocol
since Appletalk. If like me you don't want that crud junking up your
network, edit the line 'BrowseRemoteProtocols dnssd cups' in cupsd.conf
to 'BrowseRemoteProtocols none' and restart cupsd. Blessed silence will
ensue.
This is fine if you always work in the same place. During my
professional life, I used to travel to various labs and found it
convenient to automatically find, in the cups menu of my laptop, a list
of the local printers. And to always have the list up to date when the
computing department installed/removed old/new printers.
This of course requires determining a target printer's IP address and
supported network transports, when configuring printing, rather than
having it be automagical. (Quelle horreur!)
(Check the authors of Avahi, and you'll see a familiar name.)
I guess some Lennart guy is involved. I don't think he is pure
evil. The problem is that he hasn't simplicity amongst his targets. But
a few of his things works, like avahi and ifplugd. Maybe Avahi is
chatty, but I never found it on my way reversing any of my configuration
choices or forcing anything on me. After all it is just the
implementation on Linux of a protocol which is now a multi-os standard,
even if it originated in Apple (which isn't a criteria of quality). I
think one has to remain realistic and only avoid potterware when there
is choice. There is concerning systemd, thanks Devuan, and a few other,
and there is concerning pluseaudio, thanks apulse.
