NAME

     dhcpcd-run-hooks -- DHCP client configuration script


DESCRIPTION

     dhcpcd-run-hooks is used by dhcpcd(8) to run any system and user defined
     hook scripts.  System hook scripts are found in /libexec/dhcpcd-hooks and
     the user defined hooks are /etc/dhcpcd.enter-hook.  and
     /etc/dhcpcd.exit-hook.  The default install supplies hook scripts for
     configuring /etc/resolv.conf and the hostname.  Your distribution may
     have included other hook scripts to say configure ntp or ypbind.  A test
     hook is also supplied that simply echos the dhcp variables to the console
     from DISCOVER message.

     Each time dhcpcd-run-hooks is invoked, $interface is set to the interface
     that dhcpcd is run on and $reason is to the reason why dhcpcd-run-hooks
     was invoked.  DHCP information to be configured is held in variables
     starting with the word new_ and old DHCP information to be removed is
     held in variables starting with the word old_.  dhcpcd can display the
     full list of variables it knows how about by using the -V, --variables
     argument.

     Here's a list of reasons why dhcpcd-run-hooks could be invoked:

     PREINIT
             dhcpcd is starting up and any pre-initialisation should be done.

     INFORM  dhcpcd informed a DHCP server about it's address and obtained
             other configuration details.

     BOUND   dhcpcd obtained a new lease from a DHCP server.

     RENEW   dhcpcd renewed it's lease.

     REBIND  dhcpcd has rebound to a new DHCP server.

     REBOOT  dhcpcd successfully requested a lease from a DHCP server.

     EXPIRE  dhcpcd's lease expired and it failed to obtain a new one.

     IPV4LL  dhcpcd failed to contact any DHCP servers but did obtain an
             IPV4LL address.

     FAIL    dhcpcd failed to contact any DHCP servers or use an old lease.

     TIMEOUT
             dhcpcd failed to contact any DHCP servers but was able to use an
             old lease.

     TEST    dhcpcd received an OFFER from a DHCP server but will not config-
             ure the interface.  This is primarily used to test the variables
             are filled correctly for the script to process them.


FILES

     When dhcpcd-run-hooks runs, it loads /etc/dhcpcd.enter-hook and any
     scripts found in /libexec/dhcpcd-hooks in a lexical order and then
     finally /etc/dhcpcd.exit-hook
