<div><p>Use this information to understand your options when problems related
|
||
|
|
to SNTP arise. This topic describes problems that your system might encounter
|
||
|
|
when you adjust time using SNTP.</p>
|
||
|
|
<p>Log SNTP activity can help you to identify problems with the server or
|
||
|
|
client.</p>
|
||
|
|
<p>The following topics identify problems you might encounter and provide
|
||
|
|
ways to recover:</p>
|
||
|
|
<ul><li><strong>I want to contact an SNTP server through a firewall </strong><p>If you are
|
||
|
|
using the SNTP client through a firewall, the firewall configuration might
|
||
|
|
need to be updated to allow the passing of UDP packets on port 123.</p>
|
||
|
|
</li>
|
||
|
|
<li><strong>Server does not serve time to clients</strong> <p>If you have selected <span class="uicontrol">Server
|
||
|
|
must be synchronized before valid time is served</span> on the <span class="uicontrol">Server</span> page
|
||
|
|
of SNTP properties, you must have the iSeries™ server configured as an SNTP
|
||
|
|
client connected to an active time server before the server can respond to
|
||
|
|
client polls.</p>
|
||
|
|
</li>
|
||
|
|
<li><strong>I want to stop SNTP</strong> <p>If SNTP is not making correct
|
||
|
|
time adjustments or if you want to start a new time adjustment, you need to
|
||
|
|
ensure that SNTP is stopped properly.</p>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p>For more information on troubleshooting problems related to time management,
|
||
|
|
see Time management troubleshooting.</p>
|
||
|
|
<p>If the problem is outside of the SNTP topic, see Troubleshooting to learn
|
||
|
|
about the options you have regarding general problems with the iSeries server.
|
||
|
|
For additional help, see Service and support.</p>
