<para>The <application><acronym>DHCP</acronym></application> package comes with
|
|
both a client (<command>dhclient</command>) and a server program for
|
|
using <acronym>DHCP</acronym>. If you want to install this package,
|
|
the instructions can be found at <xref linkend="dhcp"/>.
|
|
Note that if you only want to use the client, you
|
|
do <emphasis>not</emphasis> need to run the server and so do not need
|
|
the startup script and links provided for the server daemon.
|
|
You only need to run the <acronym>DHCP</acronym> server if you're providing
|
|
this service to a network, and it's likely that you'll know if that's the
|
|
case; if it isn't, don't run the server! Once you have installed the
|
|
package, return here for information on how to configure the client
|
|
(<command>dhclient</command>).</para>
|
|
|
|
<para>To configure <command>dhclient</command>, you need to first install
|
|
the network service script,

<filename>/etc/sysconfig/network-devices/services/dhclient</filename>
|

included in the <xref linkend="intro-important-bootscripts"/> package.</para>

<para>Next, create the

<filename>/etc/sysconfig/network-devices/ifconfig.eth0/dhclient</filename>
|
|
configuration file with the following commands. Adjust as necessary for
|
|
additional interfaces.</para>
