NAME
showdhc - Displays the contents of DHCP client configuration files SYNOPSIS
/usr/sbin/showdhc filenames... DESCRIPTION
The showdhc command reads the files specified on the command line and, assuming they are configuration files, displays the data contained in them. The format of the output is a single line as shown in the Format section of the bootptab(4) reference page. If any of the files named on the command line is not of the correct type, diagnostic output is sent to stderr. Configuration files are identified by an internal magic number, and the major and minor release numbers of JOIN configuration files are usually written to the /etc/join directory and are named interface.dhc.

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
