This appendix covers the syntax of the dhcpd command and the dhcpd.conf configuration file. It is a reference to the Internet Software Consortium (ISC) Dynamic Host Configuration Protocol (DHCP) server, dhcpd. To fully understand how to configure and use dhcpd in realistic network environments, see the tutorial and sample configuration files in Chapter 9.
The information in this appendix is based on the version of dhcpd available at this writing. As a beta release, this software is bound to be upgraded and changed. Refer to the web page http://www.isc.org/dhcp.html for the most recent information about dhcpd. And remember, a DHCP implementation from another vendor will probably be configured in a completely different manner.
