We need a basic DNS client (and server) on the nodes. We want to use the Service Location Protocol (SLP) to implement a domain service. The domain server

Tools

avahi

Features:

  • Embeddable mDNS stack (i.e. mDNS stack available as library)
  • Ability to reflect mDNS traffic between multiple subnets
  • Ability to configure a unicast DNS server automatically from server data published on the LAN
  • Wide area DNS-SD support (read-only for now)

mdns-utils

The OpenWRT package mdns-utils is actually just compiling part of Apple's mDNSResponder.

The mDNSClient utility only outputs lines to stderr like:

 *** Found name = 'Foo', type = '_afpovertcp._tcp.', domain = 'local.'

So only the service name, service type and domain.

The code that outputs this line is in the file mDNSResponder/mDNSPosix/Client.c in the function BrowseCallback.
