avahi-autoipd(8)avahi-autoipd(8)NAMEavahi-autoipd - IPv4LL network address configuration daemon
SYNOPSISavahi-autoipd [options] interface
DESCRIPTIONavahi-autoipd implements IPv4LL, "Dynamic Configuration of IPv4 Link-
Local Addresses" (IETF RFC3927), a protocol for automatic IP address
configuration from the link-local 169.254.0.0/16 range without the need
for a central server. It is primarily intended to be used in ad-hoc
networks which lack a DHCP server.
IPv4LL is part of the Zeroconf stack.
avahi-autoipd can be used as stand-alone address allocator or as plugin
for a DHCP client such as ISC's dhclient, where it can be used as fall‐
back solution if no DHCP server is found.
To allow communication between hosts that have only an IPv4LL address
assigned and hosts that only have a routable IP address assigned you
may add the following routes to both network configurations:
route add -net 169.254.0.0 netmask 255.255.0.0 dev eth0 metric 99
route add default dev eth0 metric 99

OPTIONS-D | --daemonize
Daemonize after startup. Implies --syslog.
-k | --kill
Kill an already running avahi-autoipd on the specified network
interface. (Equivalent to sending a SIGTERM)
-r | --refresh
Tell an already running avahi-autoipd to re-announce the
acquired IP address on the specified network interface. (Equiva‐
lent to sending a SIGHUP)
-c | --check
Return 0 as return code if avahi-autoipd is already running for
the specified network interface.
-s | --syslog
Log to syslog instead of STDERR. Implied by --daemonize.
Enable verbose mode.
Don't drop root privileges after startup. We recommend not to
use this option.
Don't chroot(2) the daemon. This option is only available when
compiled with chroot() support.
-S | --start=
Try to acquire the specified IP address, which must be from the
IPv4LL range 169.254.0.0/16.
-w | --wait
Wait until a IP address has been successfully acquired before
detaching. Only valid in combination with --daemonize.
Acquire an IPv4LL address, even if a routable address has been
configured on the interface.
Don't change the process name while running. Unless this option
is specified avahi-autoipd will reflect its current state and
the IP address in the process title.
-h | --help
-v | --version
Show version information.
/home/lennart/tmp/avahi/etc/avahi/avahi-autoipd.action: the script to
run when an IP address as been acquired or is lost.
SIGINT, SIGTERM: avahi-autoipd will shutdown. (Same as --kill)
SIGHUP: avahi-autoipd will re-announce the acquired IP address. (Same
