No responses on Windows

[panta]

Hi,

I'm using multicast-dns along with bonjour in an Electron app (built with electron-builder).
While on OS X it works like a charm, on Windows machines I see my initial query, but I don't receive any response (the firewall is disabled). On some of these machines, if I launch the Bonjour Browser utility before my app, then the app will subsequently display responses.

Please note that the Windows machines I've tested are VirtualBox VMs and have multiple interfaces (the first NAT, the second bridged - the latter being the one that should receive the responses). Using wireshark I can see the incoming mdns traffic on port 5353 with destination 224.0.0.251.

Is there something I'm patently overlooking, or something I could try?

Thanks in advance.

Answering my own question. Seems due to the fact that multicast-dns binds to the first interface it finds. When multiple interfaces are present, it's necessary to listen on all of them (but this requires the multi-interace support of PR #38).

@panta yea we should get that fixed asap. just need to fix that merge conflict

I've fixed it myself if you want, in panta/multicast-dns.

Created new PR #42, with the conflict resolved. But the glory should go to @bnielsen1965 for the actual work :)

Great. Will take a look tonight.

Mathias,
You have your hands full, so I went ahead and did a major rework of multicast-dns and added it as a new npm module. Assuming I did everything correct it will be mostly backward compatible with multicast-dns and it will handle multiple network interfaces.

I thought you might want to take a look...
