Implements a Dynamic Host Configuration Protocol (DHCP) server. Serves addresses and configuration information to DHCP clients.
To Serve Information to the DHCP Clients by Using the System Resource Controller:
startsrc -s dhcpsd [ -a Argument ] [ -a Argument ] ...
To Serve Information to the DHCP Clients without Using the System Resource Controller:
dhcpsd [ -f ConfigurationFile]
The DHCP 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 accessability information. The initial database is specified by the configuration file. The configuration file contains all the data to start configuring DHCP clients.
The DHCP Server maintains a database of addresses it has given out as well as who has them. These databases are kept in the files /etc/dhcpsd.ar and /etc/dhcpsd.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.
