A terrible mDNS responder

• Written in unsafe C (buffer overflows everywhere)
• Only supports IPv4
• No proper support for multiple network interfaces
• Not portable
• Ignores most of the spec
• Will wreak havoc on your network

OK, but why?

I wanted it to work on my Hurd box. Avahi doesn't. Neither does Apple's mDNSResponder.

History

Terrible mDNS responder derives from an earlier project of mine, the Bad mDNS responder, which was not nearly as terrible: it was portable to a wide range of systems, supported both IPv4 and IPv6, tried to support multiple network interfaces properly, and so on.

Ultimately, Bad mDNS responder was a failure: it was bad enough for me not to use it on my Linux boxes, and demanded too much from the network stack to work on the Hurd. Which is why I decided to just rip most of the complexity out, and make something that works well enough for my actual needs.
