28# This file contains tunable parameters for dhcpagent(1M).
29#
30
31# All parameters can be tuned for a specific interface by prepending
32# the interface name to the parameter name.  For example, to make
33# RELEASE_ON_SIGTERM happen on all interfaces except hme0, specify:
34#
35# hme0.RELEASE_ON_SIGTERM=no
36# RELEASE_ON_SIGTERM=yes
37
38# By default, when the DHCP agent is sent a SIGTERM, all managed
39# interfaces are dropped.  By uncommenting the following
40# parameter-value pair, all managed interfaces are released instead.
41#
42# RELEASE_ON_SIGTERM=yes
43
44# When the DHCP agent gets an ACK from the server, it sends an ARP
45# request to verify that a given IP address is not already in use.  If
46# an ARP reply is received, the DHCP agent declines the server's
47# offer.  However, if the DHCP agent is unable to send the ARP request
48# packet for whatever reason, it assumes the address is available.  To
49# be more cautious, uncomment the following parameter-value pair.
50#
51# IGNORE_FAILED_ARP=no
52
53# By default, the DHCP agent waits 3 seconds to collect OFFER
54# responses to a DISCOVER.  If it receives no OFFERs in this time, it
55# then waits for another 3 seconds, and so forth.  To change this
56# behavior, set and uncomment the following parameter-value pair.
57# Note: this does not control the retransmission strategy for
58# DISCOVERs, which is formally specified in RFC 2131.  This parameter
59# is specified in seconds.
60#
61# OFFER_WAIT=
62
63# By default, the DHCP agent waits 1000 milliseconds to collect ARP
64# replies to an ARP request when verifying that an IP address is not
65# in use.  To change this behavior, set and uncomment the following
66# parameter-value pair.  This parameter is specified in milliseconds.
67#
68# ARP_WAIT=
69
70# By default, the DHCP agent does not send out a client identifier
71# (and hence, the chaddr field is used by the DHCP server as the
72# client identifier.)  To make the DHCP agent send a client
73# identifier, set and uncomment the following parameter-value pair.
74# Note that by default this is treated as an NVT ASCII string.  To
75# specify a binary value, prepend "0x" to a sequence of hexadecimal
76# digits (for example, the value 0xAABBCC11 would set the client
77# identifier to the 4-byte binary sequence 0xAA 0xBB 0xCC 0x11).
78#
79# CLIENT_ID=
80
81# By default, the DHCP agent will try to request the hostname currently
82# associated with the interface performing DHCP.  If this option is
83# enabled, the agent will attempt to find a host name in /etc/hostname.<if>,
84# which must contain a line of the form
85#
86#	inet name
87#
88# where "name" is a single RFC 1101-compliant token.  If found, the token
89# will be used to request that host name from the DHCP server.  To prevent
90# this, uncomment the following line.
91#
92# REQUEST_HOSTNAME=no
93
94# By default, a parameter request list requesting a subnet mask (1),
95# router (3), DNS server (6), hostname (12), DNS domain (15), broadcast
96# address (28), and encapsulated vendor options (43), is sent to the DHCP
97# server when the DHCP agent sends requests.  However, if desired, this
98# can be changed by altering the following parameter-value pair.  The
99# numbers correspond to the values defined in RFC 2132.
100#
101PARAM_REQUEST_LIST=1,3,6,12,15,28,43
