Mein Drucker ist nach Standby nicht zu erreichen!?

warum zur Hölle ist #avahi so besessen darauf, dass Paket vom *source port* 5353 kommen müssen?

Uh, Nice,

#Traefik läuft nun im #homelab auf dem #raspberrypi und so ganz nebenbei werden die Hostnamen via #mnds #avahi #zeroconf im local net verteilt. Dank #docker labels. Genauer gesagt: die traefik host regeln werden dafür wiederverwendet ...

(english:
#traefik is running my #homelab on the #raspberrypi and just as a side effect the hostnames are distributed via #mdns #avahi #zeroconf in my local domain. Thanks to #docker labels. Actually, the traefik host rules are re-used for this ...)

Following somebody submitting a PR to update I've spent an hour updating my Docker/Traefik/Avahi helper and pushing new Docker conatiners.

TIL: Restarting systemd services on sustained CPU abuse

I kept finding avahi-daemon pegging the CPU in some of my LXC containers, and I wanted a service policy that behaves like a human would: limit it to 10%, restart immediately if peg(...)

My #fosdem talk in #dns room got accepted! Great news for me, although I have a lot to do to present the potential I have already in my head. But not yet in the code! I want to work also on #avahi release. Well, I should relax and refresh at the same time. Combination of all that would not be a simple task. Merry Christmas everyone!

We at OpenPrinting are aware of the problem and the bug is actually in CUPS and not in GNOME/GTK.

See

https://github.com/OpenPrinting/cups/issues/176

I have originally reported this one. See the answers of CUPS author Michael Sweet. He has developed primarily under Mac OS (BSD-based) which uses mdnsresponder (Not Avahi as in Linux) where the problem does not occur, seems in CUPS' Avahi support.

Set as milestone for first CUPS 2.5.x release.

"lpstat -l -e" fails with Avahi · Issue #176 · OpenPrinting/cups

I create a CUPS queue on my locally installed CUPS and share it (turn sharing for CUPS on and also mark the printer itself shared). On remote machines it gets visible by that, as expected. Now I ca...

Is there a way to configure #avahi to only register the ULA as a new address record for #mDNS and ignore the GUA?#ipv6 #followerpower

So with the help of #chatgpt I managed to fix the issue with #Airprint and #DebianTrixie. The problem is not #Avahi - it's #CUPS frontend.

When you set up a printer over http://localhost:631 and check "Share this printer" - it won't actually reflect in /etc/cups/printers.conf

So check that file and make sure you see "Shared Yes" there.

If it still won't work - here are more steps I took to fix it:

#avahi has one important limitation on multicast resolution. It expects host has only one important address on AF. At least that is offered by simple protocol used by nss-mdns. It cannot send multiple addresses on single name. That is often wrong. Is there potential contributor able to design fix for that? #mdns
