<para>Information on configuring the dhcp client can be found in
Chapter 14.</para>

<para>Note that you only want to start the dhcp server if you want to
issue LAN addresses over your network.  The dhcp client doesn't need
this script to be used.  Also note that this script is coded for the
'eth1' INTERFACE, which may need to be modified for your hardware
configuration. With that in mind the dhcp init.d script can be created
using the following commands.</para>

<para>The lease file must exist on startup.  The following command will
satisfy that requirement:</para>

<para>The follow commands will create a base configuration file for a
dhcp server.  There are several options that you may want to
add (information that is passed back to the dhcp client) and those are
covered in the man pages for <filename>dhcp.conf</filename>.</para>
