dhcpsvc.conf(4)                  File Formats                  dhcpsvc.conf(4)

       dhcpsvc.conf - file containing service configuration parameters for the
       DHCP service

       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:


       The following Keyword and Value parameters are supported:


           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.


           Integer.  Number of seconds the server caches data from data store.
           Used to improve performance. Default is  10  seconds.  server  mode
           only parameter.


           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.


           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.


           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.


           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.


           TRUE/FALSE. Toggles ICMP echo verification of IP addresses. Default
           is TRUE. server mode only parameter.


           String. Comma-separated list  of  interface  names  to  listen  to.
           Generic parameter.


           Integer.  Local  facility number (0-7 inclusive) to log DHCP events
           to. Default is not to log transactions. Generic parameter.


           Integer. Number of  seconds  before  OFFER  cache  timeouts  occur.
           Default is 10 seconds. server mode only parameter.


           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.


           String.  Comma-separated  list of host names and/or IP addresses of
           relay destinations. relay mode only parameter.


           Integer. Max number of BOOTP relay hops before packet  is  dropped.
           Default is 4. Generic parameter.


           Integer.  Number  of  minutes  between  automatic  dhcptab rescans.
           Default is not to do rescans. server mode only parameter.


           Data store resource used. Use this parameter  to  name  the  public
           module. See the PATH keyword in dhcp_modules(5).


           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.


           server or relay. Selects daemon run mode. Default is server.


           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.


           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.


           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.
