mDNS discovery is not available.

I tried the interactive.js sample out on MacOS El Capitan, but only get the error message:

mDNS discovery is not available.

If I try to set-up a session myself, I only get

Socket is already bound

for any combination of names and ports.

Is this still compatible to El Capitan?

The mdns package is missing. You can install it with npm install mdns On Ubuntu 17.10, I had to install libavahi-compat-libdnssd-dev first. After that, instead of mDNS discovery is not available. I get several warnings about the Apple Bonjour compatibility layer of Avahi. On creating a new session, again I get Socket is already bound Any solution?
