avahi-autoipd.action(8) 				      System Manager's Manual					   avahi-autoipd.action(8)

NAME

       avahi-autoipd.action - avahi-autoipd action script

SYNOPSIS

       /home/lennart/tmp/avahi/etc/avahi/avahi-autoipd.action

DESCRIPTION

       avahi-autoipd.action  is  the action script that is called whenever an IP address has been acquired by avahi-autoipd or when it detected an
       IP address conflict. The script should add or remove the specified address from the specified network interface.

PARAMETERS

       argv[1] An event string: one of BIND, CONFLICT, UNBIND or STOP. If BIND is passed an IP address has  been  successfully	acquired  and  the
       script  shall  add  it to the network interface. If CONFLICT is passed avahi-autopid detected a IP address on the local network, the action
       script should remove the configured IP address. If UNBIND is passed the IP address should be removed from the  interface,  too,	because  a
       routable  address has been configured to the interface by some other program. If STOP is passed the avahi-autoipd is being shutdown and the
       action script should remove the IP address. In short: on BIND the address should be added to the interface, on CONFLICT, UNBIND or STOP	it
       should be removed.

       argv[2] The network interface name.

       argv[3] An IP address from the IPv4LL range.
