dhcpsvc.conf(4) File Formats 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 support of BOOTP clients.
Default is no BOOTP. Value selects BOOTP address allocation method.
automatic to support all BOOTP clients, manual to support only reg‐
istered 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 version of the public module is being used to admin‐
ister 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. Current
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 inclusive) 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 seconds. server mode only parameter.
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 automatic dhcptab rescans.
Default is not to do rescans. server mode only parameter.
RESOURCE
Data store resource used. Use this parameter to name the public
module. See the PATH keyword in dhcp_modules(5).
RESOURCE_CONFIG
String. The private layer provides for module-specific configura‐
tion information through the use of the RESOURCE_CONFIG keyword.
See dhcp_modules(5).
Providers can access RESOURCE_CONFIG using the configure function
by specifying an optional service provider layer API function:
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 con‐
tents 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 con‐
figuration 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 pri‐
mary server to respond before responding itself. Default is 20 sec‐
onds. 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 specifying 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, determining amount of status and
error messages reported by the daemon. Default is FALSE. Set to
TRUE only for debugging. Generic parameter.
