DHCPSVC.CONF(4)DHCPSVC.CONF(4)NAMEdhcpsvc.conf - file containing service configuration parameters for the
DHCP service
DESCRIPTION
The dhcpsvc.conf file resides in directory /etc/inet and contains
parameters for specifying Dynamic Host Configuration Protocol (DHCP)
service configuration settings, including the type and location of DHCP
data store used.
The description of the dhcpsvc.conf file in this man page is informa‐
tional only. The preferred method of setting or modifying values within
the dhcpsvc.conf file is by using dhcpconfig(1M) or the dhcpmgr(1M)
utility. Do not edit the dhcpsvc.conf file.
The dhcpsvc.conf file format is ASCII; comment lines begin with the
crosshatch (#) character. Parameters consist of a keyword followed by
an equals (=) sign followed by the parameter value, of the form:
Keyword=Value
The following Keyword and Value parameters are supported:
BOOTP_COMPAT
String. automatic or manual. Enables sup‐
port of BOOTP clients. Default is no BOOTP.
Value selects BOOTP address allocation
method. automatic to support all BOOTP
clients, manual to support only registered
BOOTP clients. server mode only parameter.
CACHE_TIMEOUT
Integer. Number of seconds the server
caches data from data store. Used to
improve performance. Default is 10 seconds.
server mode only parameter.
CONVER
Integer. Container version. Used by DHCP
administrative tools to identify which ver‐
sion of the public module is being used to
administer the data store. CONVER should
not be changed manually.
DAEMON_ENABLED
TRUE/FALSE. If TRUE, the DHCP daemon can be
run. If FALSE, DHCP daemon process exits
immediately if the daemon is started.
Default is TRUE. Generic parameter.
HOSTS_DOMAIN
String. Defines name service domain that
DHCP administration tools use when managing
the hosts table. Valid only when
HOSTS_RESOURCE is set to nisplus or dns.
HOSTS_RESOURCE
String. Defines what name service resource
should be used by the DHCP administration
tools when managing the hosts table. Cur‐
rent valid values are files, nisplus, and
dns.
ICMP_VERIFY
TRUE/FALSE. Toggles ICMP echo verification
of IP addresses. Default is TRUE. server
mode only parameter.
INTERFACES
String. Comma-separated list of interface
names to listen to. Generic parameter.
LOGGING_FACILITY
Integer. Local facility number (0-7 inclu‐
sive) to log DHCP events to. Default is not
to log transactions. Generic parameter.
OFFER_CACHE_TIMEOUT
Integer. Number of seconds before OFFER
cache timeouts occur. Default is 10 sec‐
onds. server mode only parameter.
OWNER_IP
String. List of supplemental ownership
addresses that will be used by the DHCP
server in determining the dhcp_network
records that are under its management.
Addresses are in the dotted Internet form
of an IPv4 address. Primary value is the
IP address associated with the system's
primary interface (nodename == hostname).
Server-mode-only parameter. Note that using
OWNER_IP has some performance impact, thus
using a large number might not be advis‐
able.
PATH
Path to DHCP data tables within the data
store specified by the RESOURCE parameter.
The value of the PATH keyword is specific
to the RESOURCE.
RELAY_DESTINATIONS
String. Comma-separated list of host names
and/or IP addresses of relay destinations.
relay mode only parameter.
RELAY_HOPS
Integer. Max number of BOOTP relay hops
before packet is dropped. Default is 4.
Generic parameter.
RESCAN_INTERVAL
Integer. Number of minutes between auto‐
matic dhcptab rescans. Default is not to do
rescans. server mode only parameter.
RESOURCE
Data store resource used. Use this parame‐
ter to name the public module. See the PATH
keyword in dhcp_modules(5).
RESOURCE_CONFIG
String. The private layer provides for mod‐
ule-specific configuration information
through the use of the RESOURCE_CONFIG key‐
word. See dhcp_modules(5).
Providers can access RESOURCE_CONFIG using
the configure function by specifying an
optional service provider layer API func‐
tion:
int configure(const char *configp);
If this function is defined by the public
module provider, it is called during module
load time by the private layer, with the
contents of the RESOURCE_CONFIG string
acquired by the administrative interface
(in the case of the dhcpmgr, through the
use of a public module-specific java bean
extending the dhcpmgr to provide a configu‐
ration dialog for this information.
RUN_MODE
server or relay. Selects daemon run mode.
Default is server.
SECONDARY_SERVER_TIMEOUT
Integer. The number of seconds a secondary
server waits for a primary server to
respond before responding itself. Default
is 20 seconds. This is a server mode only
parameter.
UPDATE_TIMEOUT
Integer. Number of seconds to wait for a
response from the DNS server before timing
out. If this parameter is present, the DHCP
daemon updates DNS on behalf of DHCP
clients, and waits the number of seconds
specified for a response before timing out.
You can use UPDATE_TIMEOUT without specify‐
ing a number to enable DNS updates with the
default timeout of 15 seconds. If this
parameter is not present, the DHCP daemon
does not update DNS for DHCP clients.
VERBOSE
TRUE/FALSE. Toggles verbose mode, determin‐
ing amount of status and error messages
reported by the daemon. Default is FALSE.
Set to TRUE only for debugging. Generic
parameter.
