Debian 10 won't run this module #252

Here's some context:

On a new, small express sample project I npm install mdns --save

debian@bgw00000000:~/prototypeF$ npm list mdns
[email protected] /home/debian/prototypeF
└── [email protected]

Then I write a simple piece of server side code in a class to broadcast that I have a web server on port 80, which looks something like this:

createmDNSAdvertisement() {
    let port = process.env.NODE_PORT || 80
    const httpAd = mdns.createAdvertisement(mdns.tcp('http'), parseInt(port))
    httpAd.start()
  }

But when I npm start, I get the following:

debian@bgw00000000:~/prototypeF$ npm start

> [email protected] start
> export $(cat .env | xargs) && nodemon main.js

[nodemon] 1.19.4

So line 31 of my service-mdns.js looks like this:

const httpAd = mdns.createAdvertisement(mdns.tcp('http'), parseInt(port))

I've read some projects which claim that lines starting with *** WARNING *** The program 'node' uses the Apple Bonjour compatibility layer of Avahi. is normal and to just ignore it. But as you can see, I can't simply ignore it. I've installed previous versions, like 5.2.1. I've tried installing/updating everything from my build tools to the avahi library installed on my system.

I'm assuming it's an issue with the npm package, but I'm not certain. Is anyone else having similar issues? If so, what fixed it for you? Or is this package being phased out as some claim?

Thanks

Following the advice from homebridge/homebridge#613:
sudo apt-get install avahi-daemon avahi-discover libnss-mdns libavahi-compat-libdnssd-dev

I rebooted the system, just to make sure everything is going, and no change:

Found this: https://www.truenas.com/community/threads/try-to-run-airsonos-issue-with-registering-on-the-network.36428/

There user @tslw says there are incorrect setting in /usr/local/etc/avahi-daemon.conf enable-dbus was set to not where it should have been yes

Went to https://manpages.debian.org/testing/avahi-daemon/avahi-daemon.conf.5.en.html and discovered the Avahi configuration file is located at /etc/avahi/avahi-daemon.conf. So I pico /etc/avahi/avahi-daemon.conf and uncommented dbus-enabled=yes. Save. Reboot the system.

Still no change in result.

Hi,
I'm currently using this module on debian 10 so I should be able to help.

I have encountered this error when a device is registered in avahi (it was found on the local network) but could no longer be resolved (I think it's the job of getaddrinfo on linux). I know of two reasons for this :

The device is no longer reachable (it can take a long time for avahi daemon to unregister dead devices)
your nss configuration doesn't allow mdns resolution

In /etc/nsswitch.conf you should have a line like :

hosts:          files mdns4_minimal mdns6_minimal [NOTFOUND=return] dns

(copied from mine, may vary. The important bit is mdns4_minimal or mdns4

If you don't care about name resolution, you can customize the name resolution step in mdns to skip it.
