avahi-daemon(8)avahi-daemon(8)NAMEavahi-daemon - The Avahi mDNS/DNS-SD daemon
SYNOPSISavahi-daemon [options]
avahi-daemon--kill
avahi-daemon--reload
avahi-daemon--check
DESCRIPTION
The Avahi mDNS/DNS-SD daemon implements Apple's Zeroconf architecture
(also known as "Rendezvous" or "Bonjour"). The daemon registers local
IP addresses and static services using mDNS/DNS-SD and provides two IPC
APIs for local programs to make use of the mDNS record cache the avahi-
daemon maintains. First there is the so called "simple protocol" which
is used exclusively by avahi-dnsconfd (a daemon which configures uni‐
cast DNS servers using server info published via mDNS) and nss-mdns (a
libc NSS plugin, providing name resolution via mDNS). Finally there is
the D-Bus interface which provides a rich object oriented interface to
D-Bus enabled applications.
Upon startup avahi-daemon interprets its configuration file
/home/lennart/tmp/avahi/usr/local/etc/avahi/avahi-daemon.conf and reads
XML fragments from /home/lennart/tmp/avahi/etc/avahi/services/*.service
which may define static DNS-SD services. If you enable publish-resolv-
conf-dns-servers in avahi-daemon.conf the file /etc/resolv.conf will be
read, too.
OPTIONS-f | --file= FILE
Specify the configuration file to read. (default:
/home/lennart/tmp/avahi/usr/local/etc/avahi/avahi-daemon.conf)
-D | --daemonize
Daemonize after startup. Implies --syslog.
-s | --syslog
Log to syslog instead of STDERR. Implied by --daemonize.
--debug
Increase verbosity to debug level.
--no-rlimits
Don't enforce resource limits as specified in the configuration
file. (See setrlimit(2) for more information)
--no-drop-root
Don't drop root privileges after startup and don't require dae‐
mon to be started as root. We recommend not to use this option.
--no-chroot
Don't chroot(2) the daemon. This option is only available when
compiled with chroot() support.
--no-proc-title
Don't change the process name while running. Unless this option
is specified avahi-daemon will reflect its current state and the
selected host name in the process title.
-k | --kill
Kill an already running avahi-daemon. (equivalent to sending a
SIGTERM)
-r | --reload
Tell an already running avahi-daemon to reread
/usr/local/etc/resolv.conf (in case you enabled publish-resolv-
conf-dns-servers in avahi-daemon.conf) the files from
/home/lennart/tmp/avahi/etc/avahi/services/. Please note that
this will not reload the
/home/lennart/tmp/avahi/etc/avahi/avahi-daemon.conf. (equivalent
to sending a SIGHUP)
-c | --check
Return 0 as return code when avahi-daemon is already running.
-h | --help
Show help
-v | --version
Show version information
FILES
/home/lennart/tmp/avahi/usr/local/etc/avahi/avahi-daemon.conf: the
default configuration file for avahi-daemon, avahi-daemon.conf(5) for
more information.
/home/lennart/tmp/avahi/usr/local/etc/avahi/hosts: additional static
hostname mappings to publish in mDNS, see avahi.hosts(5) for more
information.
/home/lennart/tmp/avahi/usr/local/etc/avahi/services/*.service: static
service definitions, see avahi.service(5) for more information.
SIGNALS
SIGINT, SIGTERM: avahi-daemon will shutdown. (Same as --kill).
SIGHUP: avahi-daemon will reload unicast DNS server data from
/usr/local/etc/resolv.conf and static service definitions from
/home/lennart/tmp/avahi/etc/avahi/services/. (Same as --reload)
SIGUSR1: avahi-daemon will dump local and remote cached resource record
data to syslog.
