NAME
     dhcpsvc.conf - file containing service configuration parame-
     ters for the DHCP service

DESCRIPTION
     The dhcpsvc.conf file resides  in  directory  /etc/inet  and
     contains  parameters  for specifying Dynamic Host Configura-
     tion Protocol (DHCP) service configuration settings, includ-
     ing the type and location of DHCP data store used.

     The description of the dhcpsvc.conf file in this man page is
     informational only. The preferred method of setting or modi-
     fying 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 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  administra-
           tive  tools  to  identify  which version 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 adminis-
           tration 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 parame-
           ter.

     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 parame-
           ter.

     PATH  Path to DHCP data tables within the data store  speci-
           fied  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
           configuration  information  through  the  use  of  the
           RESOURCE_CONFIG keyword. See dhcp_modules(5).

           Providers can access RESOURCE_CONFIG using the config-
           ure  function  by  specifying an optional service pro-
           vider layer API function:


     int configure(const char *configp);

          If this function is defined by the public  module  pro-
          vider,  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 pro-
          vide a configuration 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 respond-
           ing 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  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. Gen-
           eric parameter.
