by default listens on port 5353

[ripienaar]

I am using your hc project in my choria.io project to do some IoT work and really loving it.

Unfortunately though due to this line:

dnssd/responder.go

Line 46 in 5bf037f

var DefaultResponder, _ = NewResponder()

Even when hc is not enabled a mdns listener is started and active and talking to the network, this is not desired as I tend to run my software on very large server estates - 10s of thousands of nodes - all of them joining mDNS is a bit of a surprise :) I'd like to enable it only when configured to be enabled.

Investigating further I cannot see anywhere where this DefaultResponder is used in hc or dnssd, would it be possible to either remove this line if its unused or turn it into something thats lazy started only when needed?

I can send a PR with your guidance @brutella

thanks

I also looked around some other areas - the DefaultResponder isn't used in any of your repos. It was added here 36a2d8c but even there this DefaultResponder was never used. Seems safe to me to just remove it.

I've confirmed that removing it solves my hassles

You are right. I also think it would be better to remove the default responder completely.
