#

# This file contains tunable parameters for dhcpagent(1M).

#

# All parameters can be tuned for a specific interface by prepending

# the interface name to the parameter name. For example, to make

# RELEASE_ON_SIGTERM happen on all interfaces except hme0, specify:

#

# hme0.RELEASE_ON_SIGTERM=no

# RELEASE_ON_SIGTERM=yes

#

# An interface name alone specifies IPv4 DHCP. For DHCPv6, append ".v6".

# Some examples:

#

# hme0.RELEASE_ON_SIGTERM=no specify hme0 v4 behavior

# hme0.v6.RELEASE_ON_SIGTERM=no specify hme0 v6 behavior

# RELEASE_ON_SIGTERM=no match all v4 interfaces

# .v6.RELEASE_ON_SIGTERM=no match all v6 interfaces

# By default, when the DHCP agent is sent a SIGTERM (typically when

# the system is shut down), all managed addresses are dropped rather

# than released. Dropping an address does not notify the DHCP server

# that the address is no longer in use, leaving it possibly available

# for subsequent use by the same client. If DHCP is later restarted

# on the interface, the client will ask the server if it can continue

# to use the address. If the server either grants the request, or

# does not answer (and the lease has not yet expired), then the client

# will use the original address.

#

# By uncommenting the following parameter-value pairs, all managed

# interfaces are released on SIGTERM instead. In that case, the DHCP

# server is notified that the address is available for use. Further,

# if DHCP is later restarted on the interface, the client will not

# request its previous address from the server, nor will it attempt to

# reuse the previous lease. This behavior is often preferred for

# roaming systems.

#

# RELEASE_ON_SIGTERM=yes

# .v6.RELEASE_ON_SIGTERM=yes

# By default, the DHCP agent waits 3 seconds to collect OFFER

# responses to a DISCOVER. If it receives no OFFERs in this time, it

# then waits for another 3 seconds, and so forth. To change this

# behavior, set and uncomment the following parameter-value pair.

# Note: this does not control the retransmission strategy for

# DISCOVERs, which is formally specified in RFC 2131. This parameter

# is specified in seconds.

#

# OFFER_WAIT=

# By default, the DHCP agent does not send out a client identifier

# (and hence, the chaddr field is used by the DHCP server as the

# client identifier.) To make the DHCP agent send a client

# identifier, set and uncomment the following parameter-value pair.

# Note that by default this is treated as an NVT ASCII string. To

# specify a binary value, prepend "0x" to a sequence of hexadecimal

# digits (for example, the value 0xAABBCC11 would set the client

# identifier to the 4-byte binary sequence 0xAA 0xBB 0xCC 0x11).

#

# CLIENT_ID=

# By default, the DHCP agent will try to request the hostname currently

# associated with the interface performing DHCP. If this option is

# enabled, the agent will attempt to find a host name in /etc/hostname.<if>,

# which must contain a line of the form

#

# inet name

#

# where "name" is a single RFC 1101-compliant token. If found, the token

# will be used to request that host name from the DHCP server. To prevent

# this, uncomment the following line.

#

# REQUEST_HOSTNAME=no

# By default, a parameter request list requesting a subnet mask (1),

# router (3), DNS server (6), hostname (12), DNS domain (15), broadcast

# address (28), and encapsulated vendor options (43), is sent to the DHCP

# server when the DHCP agent sends requests. However, if desired, this

# can be changed by altering the following parameter-value pair. The

# numbers correspond to the values defined in the IANA bootp-dhcp-parameters

# registry at the time of this writing.

#

PARAM_REQUEST_LIST=1,3,6,12,15,28,43

# The default DHCPv6 parameter request list has preference (7), unicast (12),

# DNS addresses (23), DNS search list (24), NIS addresses (27), and

# NIS domain (29). This may be changed by altering the following parameter-

# value pair. The numbers correspond to the values defined in the IANA

# dhcpv6-parameters registry at the time of this writing.

.v6.PARAM_REQUEST_LIST=7,12,23,24,27,29
