avahi-daemon - The Avahi mDNS/DNS-SD daemon
avahi-daemon [options]
avahi-daemon --kill
avahi-daemon --reload
avahi-daemon --check
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 unicast 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
/etc/avahi/avahi-daemon.conf and reads XML fragments from
/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.
-
-f | --file= FILE
- Specify the configuration file to read. (default:
/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
daemon 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
/etc/resolv.conf (in case you enabled
publish-resolv-conf-dns-servers in avahi-daemon.conf) the
files from /etc/avahi/services/. Please note that this will not
reload the /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
/etc/avahi/avahi-daemon.conf: the default configuration file for
avahi-daemon,
avahi-daemon.conf(5) for more information.
/etc/avahi/hosts: additional static hostname mappings to publish in mDNS,
see
avahi.hosts(5) for more information.
/etc/avahi/services/*.service: static service definitions, see
avahi.service(5) for more information.
SIGINT, SIGTERM: avahi-daemon will shutdown. (Same as
--kill).
SIGHUP: avahi-daemon will reload unicast DNS server data from
/etc/resolv.conf and static service definitions from
/etc/avahi/services/. (Same as
--reload)
SIGUSR1: avahi-daemon will dump local and remote cached resource record
data to syslog.
