Configuring NTP Synchronization

Configuring NTP Synchronization

Operation Scenario

Configure NTP synchronization so that iBMC time automatically synchronizes with the OS time.

The following describes the configuration procedures in Windows, RHEL, and VMware.

Prerequisites

Conditions

  • A local client can communicate with the server iBMC.

  • The server OS is running properly.

Procedure (Windows)

If the server OS is Windows, iBMC time = OS time + iBMC time zone.

To ensure that the iBMC time is the same as the OS time, run the timezone command in the iBMC CLI to set the time zone to 0:00.

    Set the iBMC time zone.

    1. Log in to the iBMC CLI.
    2. Run the timezone command to set the iBMC time zone.

      For Windows, the recommended time zone of iBMC is 0:00.

      • If the iBMC time zone is 0:00, the iBMC time is the same as the OS time.
      • If the iBMC time zone is not 0:00, the iBMC time is the OS time plus the iBMC time zone.

    Change the OS time zone and time.

    1. Log in to the server OS.
    2. Change the OS time and time zone.

    Verify NTP synchronization.

    1. Five minutes later, log in to the iBMC CLI or WebUI.
    2. Query the iBMC time and verify that it is the same as the OS time.

Procedure (RHEL)

    Enable the NTP service for the OS.

    1. Log in to the server OS.
    2. On the taskbar, choose System > Administration > Services.

      The Service Configuration window is displayed, as shown in Figure 3-41.

      Figure 3-41 Service Configuration window

    3. Enable the ntpd service.

    Set the iBMC time zone.

    1. Log in to the iBMC CLI.
    2. Run the timezone command to set the iBMC time zone.

      If the server OS is RHEL, iBMC time = OS time + (iBMC time zone - RHEL time zone).

      To ensure that the IBMC time is the same as the OS time, set the iBMC time zone to be the same as the OS time zone.

Procedure (VMware)

    Modify the NTP configuration file.

    1. Log in to the server OS.
    2. Log in to the OS CLI.
    3. Edit the /etc/ntp.conf file.

      In the first line, add tos maxdist 30. In the last line, add server x.x.x.x version 3 (x.x.x.x indicates the NTP server address.)

      [root@localhost:~] vi /etc/ntp.conf
      tos maxdist 30
      restrict default kod nomodify notrap nopeer
      restrict 127.0.0.1
      server 192.168.100.100 version 3
      

    4. Restart the NTP service.

      [root@localhost:~] /etc/init.d/ntpd restart
      Stopping ntpd
      watchdog-ntpd: Terminating watchdog process with PID 37303
      Starting ntpd
      [root@localhost:~]
      

    Set the iBMC time zone.

    1. Log in to the iBMC CLI.
    2. Run the timezone command to set the iBMC time zone.

      If the server OS is VMware, iBMC time = OS time + (iBMC time zone - OS time zone).

      To ensure that the IBMC time is the same as the OS time, set the iBMC time zone to be the same as the OS time zone.
