Avahi mDNS API

[NHQ]

I realize this is no priority, b/c people on in the LAN are not probably using Linux. Nonetheless, I was not able to browse clients.

You're right. It's a non issue. Not because people are not using linux (in fact they do) but because the warning is mostly about API aesthetics. The avahi guys just like their own API better. The compat library covers everything most people will ever need.

However, not being able to browse clients is serious. It works just fine for me. Which version of node are you using? Have you tried running the test suite?

[NHQ]

Node version 6.18, but I will upgrade today and try again.

I just ran the tests. The test log follows. Avahi also spit this out during the test:

'The program "node" called "DNSServiceEnumerateDomains()" which is not supported (or only partially supported) in the Apple Bonjour compatibility layer of Avahi' [sic]

node v0.6.x should be fine. The message about DNSServiceEnumerateDomains() is OK, too. You ain't gonna need it. It's only needed for cross domain browsing, which I've never seen in use in the field.

Somehow the test log is missing. Could you paste it again?

[NHQ]

weird, sorry

Ok, looks good to me. I'm pretty sure the bug is on your side. Is your code available somewhere so I can take a quick look?

[NHQ]

LAWRD, I am such a shameful ASS!

Please forgive me! I thought I had copied working code from my other app but I left out

browser.start()

Hey, no problem. Don't blame yourself. Stuff like this happens all the time ... to all of us. The only thing that matters is that we were able to sort it out.
