Apple TV not found for pairing on Linux

[HENRIKMAK]

hello I have all the services connected and working, but my Apple TV 4k 2 gen does not show it on the atvloadly web screen. On Apple TV I wait on the App Remote and Devices screen but it just doesn't show my Linux Mint notebook connected to the same network. I tested it with the Android remote control app and it worked well, can you help me? thanks.

Run avahi-browse -a in your Linux host，can see AppleTV devices?

[HENRIKMAK]

when I run: avahi-browse -a It seems like I don't have any response, I waited 1 minute and it just sits there like in the image, with no response, even though it's running under root or without, I was thinking here if it were the case that the image didn't have access to the internet so it wouldn't locate the Apple TV but I'm already discarding this idea.

[bitxeno]

Looks like your linux host not in the same Lan network as AppleTV, atvloadly not support different subnetworks currently

[HENRIKMAK]

I was testing with the Fedora Linux distribution and using the command you gave me I would have found several networks, there must be a problem with the Linux Mint distribution, so I'm going to test on Fedora which from what I understand will recognize and locate the networks.

[HENRIKMAK]

I can get it on the OpenUse Linux distribution, but I know it works on any other distribution, just with some adjustments, I had to insert the HOSTNAME in the file: /etc/nsswitch.confas shown in image 1, then running the command: systemctl status avahi-daemon and making sure that the service is running, as in image 2, and finally running the last command to make sure everything was ok: avahi-browse -a my network detected the Apple TV and, as shown in image 3, it says pairing successfully. Thanks for the good work here, I managed to install: retroarch, provenance and mame.

Note: I'm very new to Linux and I don't speak English without the help of a translator and maybe some of the things I wrote aren't necessary, but that's how it worked for me.

Thank you for sharing.

I still wasn't able to pair. Using docker container in Ubuntu.

avahi-browse -a | grep AppleTV

But when I enter the webpage through my iphone (when apple tv is in pairing mode) - nothing happens...

It appears that you haven't correctly entered the pairing mode. When you do it right, you should see _remotepairing-manual-pairing AppleTV and make sure your tvOS version is 16.x.

I'm using tvOS 16.3.2, and I've been able to pair an iPhone, 2 macbooks and an Android remote this way, so I wonder what am I doing wrong. I've also applied @HENRIKMAK change on the host's nsswitch.conf

Did you navigate to the Remote and Devices -> Remote App and Devices menu on your AppleTV and leave it open?

Yes

Yes

You can try restart AppleTV. Without the _remotepairing-manual-pairing._tcp protocol, atvloadly cannot be used. Can you connect to AppleTV on Xcode and debug app?

[GuyKh]

I'm able to connect and pair through my macbook. Not sure what you want me to debug through XCode.

I've tried this on a second Ubuntu server I have on the same network (only avahi-daemon) and the result is the same. Are you sure no Bonjour or anything else is needed?

I do see this when entering : avahi-discover -A

+ enp0s31f6 IPv6 c8:d0:83:xx:xx:xx@xxxx::cad0:xxxx:fecc:c2c-supportsRP _apple-pairable._tcp local
+ enp0s31f6 IPv4 c8:d0:83:xx:xx:xx@xxxx::cad0:xxxx:fecc:c2c-supportsRP _apple-pairable._tcp local

When opening the console through XCode and entering the pairing screen, seeing all sorts of mDNSResponder seeing all sorts of logs eg:

[R11916] DNSServiceRegister(<mask.hash: 'AsAqVNRFSDSsEybO7EJbt77w=='>, 32498) REGISTERED

[bitxeno]

If you can see the _apple-pairable._tcp protocol, it indicates that your network is work properly. Next, execute the following command inside the atvloadly docker container.:

avahi-browse -a |grep apple

can you see _apple-pairable._tcp protocol device?

[GuyKh]

Unfortunatelly, no avahi-browse in the container; I had to run apt install avahi-utils but then -

root@f350d197a6be:/# avahi-browse -a
Failed to create client object: Access denied

One note, I'd add more debug logs (for positive and negative cases) - it makes easier debugging

Seems that the container should be privilaged:true (in docker-compose) or --privilaged in docker run.
