This information provides details about how to configure SNTP on
your iSeries™ server.
SNTP can be used to adjust system time. As most applications use
the system time, this means that those applications will obtain accurate time
from the system clock.
The options you see in iSeries Navigator depend on what version
of the i5/OS™ operating
system you are running on your server and what version of iSeries Access
for Windows® you
are using. In iSeries Navigator,
click Help or press F1 for help that describes the
procedures for your version.
To work with SNTP, follow these steps:
- In iSeries Navigator,
expand .
- Right-click SNTP and select Properties.
Click the following tabs to set the parameters:
| Select this tab |
Then do this |
|---|
| General |
Specify whether to start SNTP when TCP/IP starts. You can set this
preference for the server and the client separately. |
| Client |
Specify up to three time servers that the client can poll. Also specify
the poll interval, adjustment preferences, and logging preference. |
| Server |
Specify your logging preference. By default, the SNTP server will serve
the system time when you start it. You might want to select Server
must be synchronized before valid time is served to specify that
you want your iSeries to
act as a client to obtain time from another source before serving time to
other clients. |
In addition to iSeries Navigator, you can work with SNTP settings
using the Change SNTP Attributes (CHGNTPA) command on character-based interface.
Note: 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.
