#avahi — Public Fediverse posts

@ibims

Wenn man u.a. Geräte wie #Chromecast im Netz hat, dann merkt man schnell das diese viel...sehr viel per Multicast reden. Die einen blocken es und ich fange sie auf mit dem #mDNS Dienst. Auch bekannt als #ZeroConf, #Avahi oder #bonjour

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.

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.

#OpenPrinting #CUPS #Avahi #mDNS #DNSSD

#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

complaint: #Avahi #mDNS has a tendency to completely implode and go AWOL for very long periods of time due to certain types of network disruptions, and it's a giant pain in the ass and a huge disincentive to relying on it

I really need to get my next generation network arch figured out, including internal name resolution, but it's a quicksand topic for my brain for some reason

I've got a network speaker (a Denon Home 150) that speaks "AirPlay Remote", "AirTunes Remote", "Tidal Connect", "Spotify Connect", "HEOS Audio", and "Qobuz Connect" according to Avahi.

How can I play music on this from Linux?

My music player (Strawberry) doesn't list it or any of those protocols, and I can't set it as an audio device (which is probably a good thing).

#Avahi (#DNSSD / #RFC6763 / #mDNS / #RFC6762) is always UNSECURE, no fixed #CVE, latest build is 0.8.0 from 2020-02-18. I have specified it since a long time, there is a ticket here: https://github.com/avahi/avahi/issues/503

I've expanded the #FreeBSD handbook with a section about #zeroconf and #Avahi. (#mDNS, #DNSSD).

Feedback welcome!

P.S. If you made it this far and are wondering what wsdd2/WS-Discovery is all about: #Microsoft broke discovery of LAN devices when deprecating #SMB1.

WS-Discovery is their attempt to "fix" this, and is basically a competitor to #Bonjour / #Avahi / #Zeroconf (why couldn't MS have just used that?).

Unfortunately it means only devices implementing WS-Discovery are visible in Windows 10/11's network browser.

Fortunately there's a #FOSS utility named #wsdd2 that implements WS-Discovery on Linux.

Updated #FreshTomato #firmware on my #Netgear #R7000 #router and #ASUS RT-N66U that I use as a switch + WiFi AP.

For some reason it was a pain to get the WAN working again. Rebooting the cable modem and R7000 eventually cleared it up?

Noticed that #busybox #ntpd on the firmware doesn't respond to ntpq queries and is rather config-limited, so I installed the #entware version on the R7000's USB stick.

Also uninstalled #avahi because it's now built into the firmware - neat! Now do #wsdd2 please!

I’ve been playing with the jwilder/nginx-proxy docker container recently. It automatically generates reverse proxy entries for other containers.

It does this by monitoring when new containers are started and then inspecting the environment variables attached to the new container. If the container has the VIRTUAL_HOST variable is uses it’s value as the virtual host for nginx to proxy access to […]
