NAME

SYNOPSIS

9       avahi-autoipd [options] interface
10
11       avahi-autoipd --kill interface
12
13       avahi-autoipd --refresh interface

15       avahi-autoipd --check interface

DESCRIPTION

18       avahi-autoipd  implements  IPv4LL, "Dynamic Configuration of IPv4 Link-
19       Local Addresses" (IETF RFC3927), a protocol for  automatic  IP  address
20       configuration from the link-local 169.254.0.0/16 range without the need
21       for a central server. It is primarily intended to  be  used  in  ad-hoc
22       networks which lack a DHCP server.
23
24       IPv4LL is part of the Zeroconf stack.
25
26       avahi-autoipd can be used as stand-alone address allocator or as plugin
27       for a DHCP client such as ISC's dhclient, where it can be used as fall‐
28       back solution if no DHCP server is found.
29
30       To  allow  communication between hosts that have only an IPv4LL address
31       assigned and hosts that only have a routable IP  address  assigned  you
32       may add the following routes to both network configurations:
33
34       route add -net 169.254.0.0 netmask 255.255.0.0 dev eth0 metric 99
35
36       route add default dev eth0 metric 99
37
38       See  http://developer.apple.com/qa/qa2004/qa1357.html for more informa‐
39       tion.

46              Kill an already running avahi-autoipd on the  specified  network
47              interface. (Equivalent to sending a SIGTERM)
48
49       -r | --refresh
50              Tell an already running avahi-autoipd to reannounce the acquired
51              IP address on the specified network  interface.  (Equivalent  to
52              sending a SIGHUP)
53
54       -c | --check
55              Return  0 as return code if avahi-autoipd is already running for
56              the specified network interface.
57
58       -s | --syslog
59              Log to syslog instead of STDERR. Implied by --daemonize.
60
61       --debug

63
64       --no-drop-root
65              Don't drop root priviliges after startup. We  recommend  not  to
66              use this option.
67
68       --no-chroot
69              Don't  chroot(2)  the daemon. This option is only available when
70              compiled with chroot() support.
71
72       -S | --start=
73              Try to acquire the specified IP address, which must be from  the
74              IPv4LL range 169.254.0.0/16.
75
76       -w | --wait
77              Wait  until  a  IP  address has been sucessfully acquired before
78              detaching. Only valid in combination with --daemonize.
79
80       --force-bind
81              Acquire an IPv4LL address, even if a routable address  has  been
82              configured on the interface.
83
84       --no-proc-title
85              Don't  change the process name while running. Unless this option
86              is specified avahi-autoipd will reflect its  current  state  and
87              the IP address in the process title.
88
89       -h | --help
90              Show help.
91
92       -v | --version
