mdnsd — small multicast DNS daemon

       This mDNS-SD implementation was created in 2003 by Jeremie Miller <jer@jabber.org>.  Much later, in 2016,
       it was adopted by
       Joachim   Wiberg   <troglobit@gmail.com>   for   further   development   and   maintenance   at   GitHub:

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 -iIFACE to  only  run  on  a
       single interface.

/etc/mdns.d/*.service  mDNS-SD services to announce.

       mdnsd — small multicast DNS daemon

       This program follows the usual UNIX command line syntax. The options are as follows:

       -h      Print a help message and exit.

       -iIFACE
               Interface to announce services on.  By default mdnsd runs on all interfaces.

               Only available on Linux.

       -lLEVEL
               Set log level: none, err, notice (default), info, debug.

       -n      Run in foreground, do not detach from controlling terminal.

       -s      Use syslog even if running in foreground.

       -tTTL  Set TTL of mDNS packets, default: 1 (link-local only).

       -v      Show program version.
