as400上如何配置NTP同步啊？

qiuqiu621

我在网络内设置了NTP时间同步服务器，我想把一台AS400 的主机作为客户端连接到时间服务器上同步时间，请问AS400 上怎么操作啊？我对AS400不熟悉。谢谢各位.

<转载>;基于OS/400 V5R3设置NTP的步骤：

Step 1: Configure iSeries(TM) A as an SNTP client and server

In iSeries Navigator, expand iSeries Server A -->; Network -->; Servers -->; TCP/IP.
Right-click SNTP and select Properties.
Click the following tabs to set the parameters:
On the General tab, select Client and Server to start SNTP when TCP/IP starts.
On the Client tab, specify the following values:
Time servers: timesrvr1.external.com
Poll interval: 60 minutes
Minimum adjustment: 20 milliseconds
Maximum adjustment: 20 minutes
Adjustment threshold: Maximum adjustment
Activity logging: Only when adjusting the system clock
On the Server tab, select the following:
Select Server activity logging: Only when an error status is returned by the server

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.

Step 2: Configure your firewall to allow SNTP traffic

For this scenario, you are running a firewall on iSeries Server A. To allow SNTP traffic, you must configure the firewall to allow the passing of UDP packets on port 123. Refer to your firewall documentation for steps to complete this task.


Step 3: Configure the SNTP client on other systems in the network

After your SNTP server is running, you must configure the other systems on the network to use iSeries A as an SNTP server. Use the following steps to configure the SNTP client on iSeries server B. You may need to refer to other system documentation to configure clients in your network.

In iSeries Navigator, expand iSeries Server B -->; Network -->; Servers -->; TCP/IP.
Right-click SNTP and select Properties.
Click the following tabs to set the parameters:
On the General tab, select Client to start the SNTP client when TCP/IP starts.
On the Client tab, specify the following values:
Time servers: serverA.yourco.com
Poll interval: 60 minutes
Minimum adjustment: 20 milliseconds
Maximum adjustment: 20 minutes
Adjustment threshold: Maximum adjustment
Activity logging: Only when adjusting the system clock

Step 4: Specify SNTP as your time maintenance application

After you have configured the SNTP server and client, you need to verify the time adjustment (QTIMADJ) system value to ensure that SNTP can operate as the time maintenance application on your iSeries. If another application is listed, you must take action to ensure multiple time applications do not conflict when setting the time.

The time adjustment system value only serves as an identifier. The system does not enforce the software specified; it only identifies the software to use. This value should be maintained by the time adjustment software and is intended as an aid to prevent having multiple time adjustment applications conflict with each other. The system does not verify this value or that this software is or is not performing time adjustments. For more information, see Time management.

To set the time adjustment (QTIMADJ) system value to use SNTP for time management, follow these steps:

In iSeries Navigator, expand iSeries server A -->; Configuration and Service -->; System Values.
In the right pane, right-click Date and Time and select Properties.
On the Date and Time System Values page, click the Time tab.
In the Time maintenance application field, verify the value is either *NONE or QIBM_OS400_SNTP. Note: If the system value is set to *NONE SNTP will automatically change the value to QIBM_OS400_SNTP when the client is started. If another application is listed, you must take action to ensure multiple time applications do not conflict when setting the time.

Click OK to save your changes.
Repeat these steps for iSeries server B.
