NAME

6       avahi-daemon - The Avahi mDNS/DNS-SD daemon
7

SYNOPSIS

9       avahi-daemon [options]
10
11       avahi-daemon --kill
12
13       avahi-daemon --reload
14
15       avahi-daemon --check
16

DESCRIPTION

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

OPTIONS

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

FILES

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

SIGNALS

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.
