<h1 class="topictitle1">Scenario: Synchronize clocks with iSeries server</h1>
|
||
|
|
<div><p>This scenario demonstrates using the iSeries™ server as both an SNTP server
|
||
|
|
and an SNTP client.</p>
|
||
|
|
<div class="section"><h4 class="sectionscenariobar">Situation</h4><p>As an
|
||
|
|
administrator of your company's network, you must maintain both your iSeries server
|
||
|
|
and network clients. Time stamps are critical to your transactions, and you
|
||
|
|
need to maintain synchronization in the network. This scenario demonstrates
|
||
|
|
how you can configure SNTP on your iSeries in order to synchronize clocks
|
||
|
|
on your network.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectionscenariobar">Objectives</h4><p>In this
|
||
|
|
scenario, YourCo, Inc. wants to use the SNTP client on the i5/OS™ operating
|
||
|
|
system to receive time from an outside Network Time Protocol (NTP) server.
|
||
|
|
To maintain the time within your network, you will use your iSeries server
|
||
|
|
as an SNTP server. In addition to configuring the SNTP client and server on
|
||
|
|
your iSeries,
|
||
|
|
you will need to configure your firewall to allow the SNTP client to obtain
|
||
|
|
the time from an external NTP server.</p>
|
||
|
|
<p>The objectives of this scenario
|
||
|
|
are as follows:</p>
|
||
|
|
<ul><li>To synchronize your iSeries server with an outside NTP server.</li>
|
||
|
|
<li>To act as an SNTP server for clients within your network.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectionscenariobar">Details</h4><p>The following
|
||
|
|
figure shows the solution environment for this scenario.</p>
|
||
|
|
<div class="fignone" id="rzaktscenario1__sntprelation"><a name="rzaktscenario1__sntprelation"><!-- --></a><span class="figcap">Figure 1. SNTP as a client and a server</span><br /><img src="rzati501.gif" alt="Diagram depicting SNTP relationships within a network" /><br /></div>
|
||
|
|
<p>In <a href="#rzaktscenario1__sntprelation">Figure 1</a>, the iSeries server
|
||
|
|
(Server A) uses the SNTP application as a client and a server. The SNTP client
|
||
|
|
retrieves a time value from an external time source. You specify the address
|
||
|
|
of the external time source. The SNTP application synchronizes Server A's
|
||
|
|
coordinated universal time (UTC) with the time value from the external time
|
||
|
|
source. Then, the SNTP server (Server A) sends the time value to all SNTP
|
||
|
|
client systems (iSeries Server
|
||
|
|
B and Client A) connected to it.</p>

<div class="section"><h4 class="sectionscenariobar">Prerequisites and assumptions</h4><p>This

scenario depends on the following prerequisites and assumptions:</p>
|

|
|
<ul><li>Server A (serverA.yourco.com) is running on i5/OS V5R3 or later.</li>
|
||
|

<li><img src="./delta.gif" alt="Start of change" />Server B (serverB.yourco.com) is running on i5/OS V5R3 or

later.<img src="./deltaend.gif" alt="End of change" /></li>
|
||
|
|
<li>Server B (serverB.yourco.com) and Client A are running SNTP clients.</li>
|
||
|
|
<li>You have a time management strategy.</li>
|
||
|
|
<li>You have already set the time zone system value.</li>
|
||
|
|
<li>You want to use SNTP as the time maintenance application on your iSeries.</li>

SNTP. Before completing these tasks, complete all the necessary prerequisites.</p>
