Issue/Introduction

NTP service is not running on the TCA appliances even though NTP is set within the Appliance Management portal (9443).

Environment

3.0

3.2.x

3.3.x

Cause

• The NTP service is set to running when you set the NTP server in the Appliance Management portal. But by default the service is disabled.

4. Add the following line before systemctl restart ntpd
systemctl enable ntpd 2> /dev/null
systemctl disable systemd-timesyncd 2> /dev/null
systemctl mask systemd-timesyncd 2> /dev/null
5. Save the file
6. Perform any of the following to restart the NTP service:
   1. Login to TCA Appliance Management Port and edit and save the NTP settings
      OR
   2. Run the following commands manually on the SSH shell:
