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
