Sync the Pathfinder Clock

Clock synchronization is required both to pair Pathfinder with Cortex XDR – Analytics, and for proper network-to-process association (N2PA). You should ensure that the Pathfinder clock is correctly synced as you work through the steps to Set Up Pathfinder.
By default, the Pathfinder VM performs time synchronization using pre-configured NTP servers: rolex.usg.edu,ntp2.netwrx1.com, and 0.north-america.pool.ntp.org. You can view the default NTP servers by opening the Pathfinder VM console menu, and selecting info:

You can also enable a VMware ESX host to perform time synchronization for the Pathfinder VM or configure Pathfinder use a different NTP server than the pre-configured, default NTP servers.
In any case where Pathfinder is using an external NTP server to sync it’s clock (including the default NTP servers), you must ensure that the perimeter firewall allows the traffic between Pathfinder and the NTP server.
  • Specify an internal NTP server to sync the Pathfinder clock, or an external NTP server that is different from the pre-configured NTP servers.
    1. Open the Pathfinder VM console and select NTP Server.

    2. Add the NTP server and click OK to save your settings.

    3. For an NTP server that is external to your network, ensure that the perimeter firewall is configured to allow the traffic between Pathfinder and the NTP server.
  • Enable a VMware ESX host to perform time synchronization for Pathfinder:
    1. In the vSphere Client, ensure that the VMware ESX host is configured to Synchronize guest time with host:

    2. Check that the NTP Server settings on the Pathfinder VM console are clear:
      Log into the Pathfinder VM console, select NTP Server and validate that there is no NTP Server specified.
