NTP service fails to start after new install of Aria Operations for Networks Collector 6.11. During bootup will see messages "NTP is NOT-IN-SYNC".
Attempts to manually start NTP service will fail with "Failed to start ntp.service: Unit ntp.service not found".
Running "ntp show" will show configured NTP server with a keyword "nts".
The "Secure NTP Server" option was chosen during the deployment phase, but the designated NTP server doesn't support a security feature.
Installing VMware Aria Operations for Networks VMware Aria Operations for Networks 6.11
If secure NTP was selected during setup then "ntp show" and /etc/ntp.conf will have a line with keyword “nts”.
During deployment, if secure NTP is not supported then when asked to "Configure NTP or secure NTP", type "n".
To resolve issue:
1. Ssh to Networks Collector appliance as a user "support".
2. Change user to Ubuntu user by typing "ub".
(cli) ub
3. Edit /etc/ntp.conf, at the end of the file remove keyword “nts”, and save file.
ubuntu@vrni:~$ vi /etc/ntp.conf
ubuntu@vrni:~$ cat /etc/ntp.conf
4. Login to Networks Collector appliance as a user "consoleuser" and sync NTP server.
(cli) ntp sync
(cli) ntp show
