dhcpsdv6 Daemon

Purpose

Implements a Dynamic Host Configuration Protocol (DHCPv6) server. Serves addresses and configuration information to DHCPv6 clients.

Syntax

To Serve Information to the DHCPv6 Clients by Using the System Resource Controller:

startsrc -s dhcpsdv6 [ -a "Argument" ]

To Serve Information to the DHCP Clients without Using the System Resource Controller:

dhcpsdv6 [-d] [ -f ConfigurationFile] [-a DadminPort] [-p ServerPort]

Description

The DHCPv6 Server handles the assignment and maintenance of dynamic address assignment. It also handles the distribution of additional configuration information. The dhcpsd daemon runs in the background and maintains a database of server information that contains logging parameters, IP (Internet Protocol) address ranges, other network configuration information, and accessibility information. The initial database is specified by the configuration file. The configuration file contains all the data to start configuring DHCP clients.

The DHCPv6 Server maintains a database of addresses it has given out as well as who has them. These databases are kept in the files /etc/dhcpv6/db_file.crbk and /etc/dhcpv6/db_file.cr. A server on startup will read the configuration file and setup its initial database of available addresses. The server accepts the refresh command or a SIGHUP signal to reread the configuration file.

Flags

Item Description
-a Specifies the Dadmin port; by default it is 942.
-d Displays debugging information.
-f ConfigurationFile Specifies the configuration file to be used. By default, the configuration file is /etc/dhcpv6/dhcpsdv6.cnf.
-p Specifies the port used by the server to listen for incoming request; by default it is 547.
