Technical Tip: How to troubleshoot NTP synchronization on FortiNAC-F

[ndumaj]

Description	This article describes how to verify that FortiNAC is synchronized with NTP Server. The external server is used to synchronize or update the clock on the selected FortiNAC server. Default Server set is ntp1.fortiguard.com.
Scope	FortiNAC-OS, FortiNAC-F v7.2.x or greater.
Solution	Check if the NTP server is specified in the Administration Console under System -> Settings -> System Management -> NTP and Time Zone is reachable. Figure 1. Specify the NTP Server on FortiNAC GUI. Once the NTP Server has been changed in the GUI, the system will be restarted. To verify the NTP server reachability and synchronization, use the following CLI command: FortiNAC_CLI # execute enter-shell Fortinac_CLI:~$ timedatectl status Local time: Tue 2024-08-06 11:39:45 CEST Universal time: Tue 2024-08-06 09:39:45 UTC RTC time: Tue 2024-08-06 09:39:45 Time zone: Europe/Berlin (CEST, +0200) System clock synchronized: yes NTP service: active RTC in local TZ: no Verify the NTP Synchronization status: FortiNAC_CLI:~$ systemctl status systemd-timesyncd ● systemd-timesyncd.service - Network Time Synchronization Loaded: loaded (/lib/systemd/system/systemd-timesyncd.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2024-07-25 15:09:03 CEST; 1 week 4 days ago Docs: man:systemd-timesyncd.service(8) Main PID: 1938 (systemd-timesyn) Status: "Initial synchronization to time server 208.91.112.61:123 (ntp1.fortiguard.com)."
