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 returns a service (or files) from a destination (typically based on an IP address), such as google.com resolves the servers at the 74.125.224.65 address.
Software
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 (name, service type, and domain):
*** Found name = 'Foo', type = '_afpovertcp._tcp.', domain = 'local.'
The code that outputs this line is in the file mDNSResponder/mDNSPosix/Client.c in the function BrowseCallback.
