NAME

dhcpcd-run-hooks - DHCP client configuration script  

DESCRIPTION

is used by dhcpcd(8) to run any system and user defined hook scripts. System hook scripts are found in /lib/dhcpcd/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 is invoked, $interface is set to the interface that dhcpcd is run on and $reason is to the reason why 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 could be invoked:

PREINIT
dhcpcd is starting up and any pre-initialisation should be done.
CARRIER
dhcpcd has detected the carrier is up. This is generally just a notification and no action need be taken.
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.
IPV4LL
dhcpcd failed to contact any DHCP servers but did obtain an IPV4LL address.
STATIC
dhcpcd has been configured with a static configuration which has not been obtained from a DHCP server.
3RDPARTY
dhcpcd is monitoring the interface for a 3rd party to give it an IP address.
TIMEOUT
dhcpcd failed to contact any DHCP servers but was able to use an old lease.
EXPIRE
dhcpcd's lease or state expired and it failed to obtain a new one.
NAK
dhcpcd received a NAK from the DHCP server. This should be treated as EXPIRE.
NOCARRIER
dhcpcd lost the carrier. The cable may have been unplugged or association to the wireless point lost.
FAIL
dhcpcd failed to operate on the interface. This normally happens when dhcpcd does not support the raw interface, which means it cannot work as a DHCP or ZeroConf client. Static configuration and DHCP INFORM is still allowed.
STOP
dhcpcd stopped running on the interface.
DUMP
dhcpcd has been asked to dump the last lease for the interface.
TEST
dhcpcd received an OFFER from a DHCP server but will not configure the interface. This is primarily used to test the variables are filled correctly for the script to process them.

 

FILES

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