mdnsd For Linux

"mdnsd" is a very lightweight, simple, portable, and easy to integrate open source implementation of Multicast DNS (part of Zeroconf, also called Rendezvous by Apple) for developers. It supports both acting as a Query and a Responder, allowing any software to participate fully on the .localnetwork just by including a few files and calling a few functions. All of the complexity of handling the Multicast DNS retransmit timing, duplicate suppression, probing, conflict detection, and other facets of the DNS protocol is hidden behind a very simple and very easy to use interface, described in the header file. The single small c source file has almost no dependencies, and is portable to almost any embedded platform. Multiple example applications and usages are included in the download, including a simple very persistent query browser and a tool to advertise local web sites.
