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.

OPTIONS

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

     -h      Print a help message and exit.

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

             Only available on Linux.

     -l LEVEL
             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.

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

     -v      Show program version.

FILES

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

AUTHORS

     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:
