NAME

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

DESCRIPTION

10       The dhcpsvc.conf file  resides  in  directory  /etc/inet  and  contains
11       parameters  for  specifying  Dynamic Host Configuration Protocol (DHCP)
12       service configuration settings, including the type and location of DHCP
13       data store used.
14
15
16       The  description  of the dhcpsvc.conf file in this man page is informa‐
17       tional only. The preferred method of setting or modifying values within
18       the  dhcpsvc.conf  file  is  by using dhcpconfig(1M) or the dhcpmgr(1M)
19       utility. Do not edit the dhcpsvc.conf file.
20
21
22       The dhcpsvc.conf file format is ASCII; comment  lines  begin  with  the
23       crosshatch  (#)  character. Parameters consist of a keyword followed by
24       an equals (=) sign followed by the parameter value, of the form:

128                                   ter to name the public module. See the PATH
129                                   keyword in dhcp_modules(5).

132       RESOURCE_CONFIG             String. The private layer provides for mod‐
133                                   ule-specific   configuration    information

135                                   word. See dhcp_modules(5).
136
137                                   Providers can access RESOURCE_CONFIG  using
138                                   the  configure  function  by  specifying an
139                                   optional service provider layer  API  func‐
140                                   tion:
141
142                                     int configure(const char *configp);
143
144                                   If  this  function is defined by the public
145                                   module provider, it is called during module
146                                   load  time  by  the private layer, with the
147                                   contents  of  the  RESOURCE_CONFIG   string
148                                   acquired  by  the  administrative interface
149                                   (in the case of the  dhcpmgr,  through  the
150                                   use  of  a public module-specific java bean
151                                   extending the dhcpmgr to provide a configu‐
152                                   ration dialog for this information.
153
154
155       RUN_MODE                    server  or  relay. Selects daemon run mode.
156                                   Default is server.
157
158
159       SECONDARY_SERVER_TIMEOUT    Integer. The number of seconds a  secondary
160                                   server   waits  for  a  primary  server  to
161                                   respond before responding  itself.  Default
162                                   is  20  seconds. This is a server mode only
163                                   parameter.
164
165
166       UPDATE_TIMEOUT              Integer. Number of seconds to  wait  for  a
167                                   response  from the DNS server before timing
168                                   out. If this parameter is present, the DHCP
169                                   daemon   updates  DNS  on  behalf  of  DHCP
170                                   clients, and waits the  number  of  seconds
171                                   specified for a response before timing out.
172                                   You can use UPDATE_TIMEOUT without specify‐
173                                   ing a number to enable DNS updates with the
174                                   default timeout  of  15  seconds.  If  this
175                                   parameter  is  not present, the DHCP daemon
176                                   does not update DNS for DHCP clients.
177
178
179       VERBOSE                     TRUE/FALSE. Toggles verbose mode, determin‐
180                                   ing  amount  of  status  and error messages
181                                   reported by the daemon. Default  is  FALSE.
182                                   Set  to  TRUE  only  for debugging. Generic
183                                   parameter.
