18 The Avahi mDNS/DNS-SD daemon implements Apple's Zeroconf architecture
19 (also known as "Rendezvous" or "Bonjour"). The daemon registers local
20 IP addresses and static services using mDNS/DNS-SD and provides two IPC
21 APIs for local programs to make use of the mDNS record cache the avahi-
22 daemon maintains. First there is the so called "simple protocol" which
23 is used exclusively by avahi-dnsconfd (a daemon which configures uni‐
24 cast DNS servers using server info published via mDNS) and nss-mdns (a
25 libc NSS plugin, providing name resolution via mDNS). Finally there is
26 the D-Bus interface which provides a rich object oriented interface to
27 D-Bus enabled applications.
28
29 Upon startup avahi-daemon interprets its configuration file
30 /etc/avahi/avahi-daemon.conf and reads XML fragments from
31 /etc/avahi/services/*.service which may define static DNS-SD services.
32 If you enable publish-resolv-conf-dns-servers in avahi-daemon.conf the
33 file /etc/resolv.conf will be read, too.
34
36 -f | --file= FILE
37 Specify the configuration file to read. (default:
38 /etc/avahi/avahi-daemon.conf)
39
40 -D | --daemonize
41 Daemonize after startup. Implies --syslog.
42
43 -s | --syslog
44 Log to syslog instead of STDERR. Implied by --daemonize.
45
46 --debug
47 Increase verbosity to debug level.
48
49 --no-rlimits
50 Don't enforce resource limits as specified in the configuration
51 file. (See setrlimit(2) for more information)
52
53 --no-drop-root
54 Don't drop root privileges after startup and don't require dae‐
55 mon to be started as root. We recommend not to use this option.
56
57 --no-chroot
58 Don't chroot(2) the daemon. This option is only available when
59 compiled with chroot() support.
60
61 --no-proc-title
62 Don't change the process name while running. Unless this option
63 is specified avahi-daemon will reflect its current state and the
64 selected host name in the process title.
65
66 -k | --kill
67 Kill an already running avahi-daemon. (equivalent to sending a
68 SIGTERM)
69
70 -r | --reload
71 Tell an already running avahi-daemon to reread /etc/resolv.conf
72 (in case you enabled publish-resolv-conf-dns-servers in avahi-
73 daemon.conf) the files from /etc/avahi/services/. Please note
74 that this will not reload the /etc/avahi/avahi-daemon.conf.
75 (equivalent to sending a SIGHUP)
76
77 -c | --check
78 Return 0 as return code when avahi-daemon is already running.
79
80 -h | --help
81 Show help
82
83 -v | --version
84 Show version information
85
87 /etc/avahi/avahi-daemon.conf: the default configuration file for avahi-
88 daemon, avahi-daemon.conf(5) for more information.
89
90 /etc/avahi/hosts: additional static hostname mappings to publish in
91 mDNS, see avahi.hosts(5) for more information.
92
93 /etc/avahi/services/*.service: static service definitions, see
94 avahi.service(5) for more information.
95
97 SIGINT, SIGTERM: avahi-daemon will shutdown. (Same as --kill).
98
99 SIGHUP: avahi-daemon will reload unicast DNS server data from
100 /etc/resolv.conf and static service definitions from /etc/avahi/ser‐
101 vices/. (Same as --reload)
102
103 SIGUSR1: avahi-daemon will dump local and remote cached resource record
104 data to syslog.
