Use mdns.Browser over VPN connection about node_mdns HOT 3 CLOSED

I would also like to clarify that unlike the approach made in #244, I've mounted the dbus system bus socket and started the avahi-daemon inside the container, because I need the service to see the interface wg0 and make any multicast request through it.

Hi @manuelnucci,

node_mdns probably isn't at fault here. Most VPNs simply don't support this type of service discovery (out of the box). See

• https://superuser.com/questions/1490332/time-machine-detection-over-vpn-via-dns-sd

... for example. Just google for "vpn dnssd" "wireguard vpn bonjour" etc. Also, to exclude node_mdns as a source of bugs replace your node script with a simple avahi-browse command for now. Get it to work on the command line first and then switch back to node_mdns.

Hi @agnat! Yes, I should've made the test you suggest before any attempt to use the library. As you said, it's not clear if WG supports multicast.

Hopefully I will find the answer this week and will be able to use this library or not. Thanks for all the info.
