9.2.1. Procedure – Configuring NTP with ZMC

NTP has a separate configuration component in ZMC.

1. Add the Time component to the Zorp host in ZMC. It is recommended to select the Date and time template.

   

   Figure 9.4. Adding the Time component

2. Name the component.

3. Specify a time server with which Zorp synchronizes its system time.

4. Configure the Time subcomponents. Date and time can be updated from the specified time server by clicking Run now, or set manually.

   1. Set date and time information manually, using the three-dotted (...) button.

      

      

      Figure 9.7. Editing time and date values manually

      If the date and time values are set manually, a dialog box gives a warning that instead of setting these values manually, it is recommended to force an update from the configured timeserver with the ntpdate command. To synchronize the time to the time server, click the Run now button in the bottom of the window.

      It is recommended to use ntpdate instead of manually tuning date and time values because the Internet time is probably more accurate than other, local time sources.

   2. If you want to permit your clients to synchronize their clocks to the Zorp host, enable the ntp local service. See Section 9.4, Local services on Zorp for details.

   3. List the NTP servers Zorp can communicate with.

      For time synchronization fault tolerance, It is recommended to add at least two servers to the list. Click New and enter the address of the NTP server, as well as the interval when the clock of the Zorp host should be synchronized to the NTP server.
