NAME avahi-autoipd - IPv4LL network address configuration daemon
SYNOPSIS avahi-autoipd [options] interface
avahi-autoipd --kill interface
avahi-autoipd --refresh interface
avahi-autoipd --check interface
DESCRIPTION avahi-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 ISCs 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
See http://developer.apple.com/qa/qa2004/qa1357.html for more informa- tion.
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 reannounce the acquired IP address on the specified network interface. (Equivalent 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.
--debug Enable verbose mode.
--no-drop-root Don t drop root priviliges after startup. We recommend not to use this option.
--no-chroot Dont 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 sucessfully acquired before detaching. Only valid in combination with --daemonize.
--force-bind Acquire an IPv4LL address, even if a routable address has been configured on the interface.
--no-proc-title Dont 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 Show help.
-v | --version Show version information.
FILES /etc/avahi/avahi-autoipd.action: the script to run when an IP address as been acquired or is lost.
SIGNALS SIGINT, SIGTERM, SIGQUIT: avahi-autoipd will shutdown. (Same as --kill)
SIGHUP: avahi-autoipd will reannounce the acquired IP address. (Same as --refresh)
