[Touch-packages] [Bug 1616196] Re: unable to stop avahi-daemon (dbus always restarts it)
Wow, super annoying. I just wanted the "[UFW BLOCK]" multicast messages
to stop clogging up my logs when I'm connected to certain networks. I
don't really want it permanently disabled, nor do I really want to
change firewall rules, just to stop cluttering the log. Avahi just
doesn't make sense on every network and it would be great if there were
a way to stop it temporarily, without resorting to permanently disabling
it. This is still happening in latest 19.10, fyi.

Indeed, let's see when it lands in Ubuntu then _maybe_ we could look
into SRU'ing those bits.

Good news for you is that some work is going on upstream in libnss-mdns right
now to fix this problem properly and always handle .local properly even when in
authorative DNS - some commits just went in recently Adam Goode is doing some
great work on this project:
https://github.com/lathiat/nss-mdns
Bad news is it's unlikely to ship in an existing release (i.e. LTS) but
hopefully will be part of some future Ubuntu release.

Disabling and stopping the socket and the service works for the manual
case, thanks.

Unfortunately for me because I'm trying to remotely disable avahi-daemon
for clients connecting to a corporate VPN where "domain.local" is used
as the DNS zone.
I haven't found any valid workaround for the ifupdown script so I now
have to instruct every clients to do the disable/stop steps themselves.
This in turn has some undesired ramifications as avahi remains inactive
even when they are off of the VPN.

I just noticed that you are an avahi developer so maybe it's my lucky
day :)
I don't know why but avahi doesn't seem to limit itself to resolving
single DNS label under ".local"? Currently, it will blackhole queries
for "server.domain.local". This makes it close to impossible to use a
DNS zone under ".local". While I know that using ".local" isn't ideal,
it was the recommended way in the past [1] and it's how many networks
are setup.
The RFC [2] mentions that ".local" is for single labels and OS X also
implementation this rule [3]. Do you think it would be possible for
avahi to also implement this behavior?
Best regards,
Simon

[Touch-packages] [Bug 1616196] Re: unable to stop avahi-daemon (dbus always restarts it)
The d-bus activation thing is a quirk of systemd, it actually tells you
when you run stop. You need to use disable (as well as stop) to both
stop it and prevent re-activation.
root@ubuntu:~# systemctl stop avahi-daemon
Warning: Stopping avahi-daemon.service, but it can still be activated by:
avahi-daemon.socket
You're right about the ifupdown script, though.
The good news on the one hand is that upstream hopefully soon nss-mdns will be
improved to no longer need this trick.

Title:
unable to stop avahi-daemon (dbus always restarts it)
Status in avahi package in Ubuntu:
New
Bug description:
When avahi-daemon is stopped, dbus always revives it.
Steps to reproduce:
1. sudo systemctl stop avahi-daemon.socket
2. sudo systemctl stop avahi-daemon.service
3. ps aux| grep avahi # should return nothing
Currently, dbus revives it right away as shown in syslog:

This automatic revival defeats the purpose of the up script [*] to deactivate
avahi when .local is a regular DNS zone (not mDNS). This also goes against the
principle of least surprise.
