NAME
mdnsd – small multicast DNS daemon
SYNOPSIS
mdnsd [-hnsv] [-i IFACE] [-l LEVEL] [-t TTL] [PATH]
DESCRIPTION
mdnsd is a small mDNS-SD daemon for UNIX like systems. It is based on an original implementation made by Jeremie Miller in 2003. Multicast DNS with service discovery (-SD) is an open standard defined in RFC5762, mDNS-SD in RFC6763, commonly known to end-users as Bonjour or Avahi, depending on the operating system.
mdnsd reads service definitions of services to announce from /etc/mdns.d/*.service, a different path may be given on the command line, which can be a directory or a single service file.
mdnsd by default runs on all multicast capable interfaces on a system. Use -i IFACE to only run on a single interface.
