NAME

       dhcpdb2conf - convert DHCP client database to config file parameters

SYNOPSIS

       index] [lan-interfaces]

DESCRIPTION

       The  command  translates a client system's DHCP database parameters (from into a set of standard configuration file parameters.	This is an
       essential step for configuring a DHCP client system, and is invoked by upon every reboot when DHCP is active.

       A DHCP client database can contain settings for such items as: hostname, IP address, and default gateway (a subset of the "initial identity
       parameters" managed by and You can list the contents of the database to the screen, create a set of configuration staging files, or execute
       direct edits on existing configuration files using the values contained in the client database.

       Arguments: You can provide a list of lan-interfaces on which to operate, such as "lan0 lan1".  If you specify no LAN interfaces,  processes
       all  entries  referenced in the client's DHCP database.	The entries are each defined as a unique LAN interface and a corresponding list of
       attributes.

   Options
       The following options determine the results of DHCP parameter processing.

       Print results to the screen (standard output).
		   This is the default action if neither nor is specified.

       Apply directly:	Using the results of the specified filters (see below),
		   directly apply the parameter definitions to the existing configuration files, for example, to (This is how is called from

       Create copies:  Create a set of staging files using the results of the
		   selected filters (see below).  Each parameter processed is applied to its corresponding copy of one configuration file [re]cre-
		   ated by

		   For	example,  is  copied  to  (If the file already exists and can be written, it is overwritten; otherwise the command fails.)
		   Once this staging file is created, the parameter being processed is applied to the newly created staging file rather  than  the
		   real configuration file.

       The  following  "filter"  options  control which parameters are processed.  The options can be combined in any manner.  The default with no
       options is to process all attributes for each LAN interface.

       Hostname:  Process the
		   parameter.

       DNS:  Process the
		   parameter set (in

       Interface:  Process the
		   parameter set:

       Route:  Process the
		   parameter set:

       NIS:  Process the
		   parameter set:

       Time:  Process the
		   parameter.

       DHCP_SERVER:  Prints the hostname of
		   which has the given IP address for the interface.  Options or have no effect.  Option will print results  only  to  the  screen
		   (standard output).

       Hostname:  Do not update the
		   parameter in configuration files.  If the option is used with or then the option has no effect.

       Set array index for the set of related parameters for one LAN interface
		   in the configuration files.	For example, with (the default) the output would include

       The command can be run only by users with appropriate privileges.

   Configuration Files and Parameter Names
       The following files, and parameters in each file, can be processed by

       EXAMPLES
	      List the entire contents of the DHCP client database:

       List only the parameter set for lan0:

       List the and parameter sets for lan0 and lan1:

       Apply the and parameter sets for lan0 to the existing configuration files:

       Apply all parameter sets to the existing configuration files using lan0, and set index = 1:

WARNINGS

       Using the option overrides any existing values which are currently set in the system's configuration files (while the option merely revises
       staging files, if any).
