Linux – avahi-daemon binds to eth0 udp ports 5353 and 53791

avahi-daemon continues to bind to eth0 ports 5353 and 53791. Is there any way to tell avahi-daemon to only bind to localhost and not eth0 ?

/etc/avahi/avahi-daemon.conf

use-ipv4=yes
use-ipv6=no
allow-interfaces=lo
deny-interfaces=eth0

netstat -nap

udp   0   0 0.0.0.0:53791   0.0.0.0:*   3145/avahi-daemon:
udp   0   0 0.0.0.0:5353    0.0.0.0:*   3145/avahi-daemon:

avahi-daemon implements Zeroconf network configuration protocol. It is useless unless it operates on network interface. You can select on which network interface you want it to run using "allow-interfaces" and "deny-interfaces" directives, but if you do not want to run in on any real network interface (as you seem), then you should not be running it at all, so simply shut it down (for example by putting exit 0 in /etc/default/avahi-daemon) or even better remove the package completely if you do not plan to using it in the future.

It does not make any sense to run it only at lo interface.
