Windows discovering avahi #40

Closed brtthomp closed 7 years ago

brtthomp commented 7 years ago

I have a linux machine running the avahi-daemon service that I am trying to discover with my windows 10 machines using this bonjour plugin. I seem to be having issues when using a windows 10 tablet (Surface Pro). The bonjour plugin isn't able to find any services whereas if I run bonjour browser (https://hobbyistsoftware.com/bonjourbrowser) the bonjour services are visible. I originally thought this might be a firewall issue but if the bonjour browser is discovering them I would think otherwise.

It also doesn't seem to be specifically windows 10 related as I have other windows 10 machines that are working just fine. This happens on multiple different Surface Pro tablets as well.

Any ideas?

Could you drop a piece of code? Or trace with Wireshark?

I'm using pretty simple code:

const bonjour = require('bonjour')();

bonjour.find({}, function(service) {
    console.log(service);
});

I could link a wireshark but it would be empty because it seems like the initial mdns query is never sent across the wire. Even doing a TCP dump on the device itself doesn't show anything. I dug a little deeper and traced the query sending all the way to dgram.js which seems to say it successfully sent the 46 bytes without error though nothing still shows up.

I'm going to close this. It seems to be with multicast-dns that is being used that doesn't currently support multiple interfaces.
