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 (SRC):
startsrc -s dhcpsdv6 [-a Argument]
To serve information to the DHCP clients without using SRC:
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 provided and 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 reads 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.
