<div><p>You can learn how to set up DHCP and DNS on two different iSeries™ servers

to perform dynamic updates over a simple LAN.</p>
|

<div class="section"><p>The following illustration depicts a small subnet
|
||
|
|
network with DNS and DHCP running on separate iSeries servers. The iSeries server
|
||
|
|
running DNS will be configured the same as when DNS and DHCP are
|
||
|
|
on the same iSeries.
|
||
|
|
However, there are some additional steps to configure the DHCP server to send
|
||
|
|
dynamic updates.</p>

that will be running DHCP, in this case, myiseries2. This option contains

the dynamic update API that manages the resource record update process. Refer

<dt class="dlterm">Authorize DHCP to send updates to DNS</dt>
|

<dd>You must authorize the DHCP server to send updates to the DNS server.
|

You can either repeat the process of defining the Dynamic Update Key, or you
|
||
|
|
can send the file and place it in the proper directory path. <div class="p">To create
|
||
|
|
a Dynamic Update Key on both iSeries servers, follow these steps:<ol><li>In <span class="uicontrol">iSeries Navigator</span>, expand <span class="menucascade"><span class="uicontrol">your
|
||
|
|
iSeries server</span> > <span class="uicontrol">Network</span> > <span class="uicontrol">Servers</span> > <span class="uicontrol">DNS</span></span>.</li>
|
||
|
|
<li>In the left pane, right-click <span class="uicontrol">DNS</span> and select <span class="uicontrol">Manage
|
||
|
|
Dynamic Update Keys...</span></li>
|
||
|
|
<li>On the <span class="uicontrol">Managing Dynamic Update Keys</span> page, select <span class="uicontrol">Add...</span></li>
|
||
|
|
<li>On the <span class="uicontrol">Add Dynamic Update Keys</span> page, complete the
|
||
|
|
following fields: <ul><li> <span class="uicontrol">Key name</span>: Specify the name for the key, for example <samp class="codeph">mycompany.key.</samp> The
|
||
|
|
key name must be dot-terminated.</li>
|
||
|
|
<li> <span class="uicontrol">Dynamic update zones</span>: Specify the zone names for
|
||
|
|
which this key will be valid. You can specify more than one zone.</li>
|
||
|
|
<li> <span class="uicontrol">Generate key</span>: Select the method that you want
|
||
|
|
to use to generate a secret key.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>Repeat the preceding steps so that the same key is defined on both the iSeries running
|

DNS and the iSeries running
|
||
|
|
DHCP.</li>
