When running avahi-browse -arvp I only get results back from my own laptop, but nothing else (I ran avahi-browse -arvp on my Pi and I get all the network devices)

So I copied the /etc/avahi/avahi-daemon.conf from my Pi to my laptop, restarted the avahi-daemon, but still only results from my own laptop...

I removed and reinstalled avahi, but still only results from my own laptop... what am i missing here?

This used to work, but then for some reason, it stopped showing network connected devices and honesty I have no idea where to start looking to fix this.

  • Do you have any kind of firewall running that might be interfering with multicast traffic? – steeldriver Sep 17 '20 at 15:35
  • no firewall, it worked before and for some reason (i don't know why) it stopped working (doesn't find any network device) – WingZero Sep 21 '20 at 07:51

I had the same problem on my RPi(Ubuntu). The cause of it is to collision of .local domain in my local network. Avahi detects that .local is used, then it stops itself.

So you should change /etc/default/avahi-daemon file like:

# AVAHI_DAEMON_DETECT_LOCAL=1
AVAHI_DAEMON_DETECT_LOCAL=0

On Rocky Linux 9 (RHEL, CentOS) avahi-browse didn't show anything for me because by default mdns is not allowed by firewall for the zone "public" which is assigned to any wireless connection. I had to reassign my wi-fi to firewall zone "home" by running:

sudo firewall-cmd --zone=home --change-interface=wlp8s0f3u4

where "wlp8s0f3u4" is my wi-fi interface name. You can get it from

ip a

It should have a name starting with "wl"
