<para>Information on configuring the <acronym>DHCP</acronym> client can be
|
|
found in Chapter 14.</para>
|
|
|
|
<para>Note that you only want to start the <acronym>DHCP</acronym> server if
|
|
you want to issue <acronym>LAN</acronym> addresses over your network. The
|
|
<acronym>DHCP</acronym> client doesn't need this script to be used. Also note
|
|
that this script is coded for the <emphasis role="strong">eth1</emphasis>
|
|
interface, which may need to be modified for your hardware configuration.
|
|
With that in mind the <command>dhcp</command> init.d script can be created
|
|
using the following commands.</para>
