Issue/Introduction

Appneta Portal: Seeing Monitoring point error flag showing NTP Errors:

Webadmin: NTP Server is in sys.peer condition and NTP Sychronized - Yes.

Cause

NTP Traffic not allowed in both directions. This typically happens when Outbound is allowed, but Inbound is blocked on UDP Port 123

Resolution

Run the following command from CLI: /opt/pathview/lib/python3/Pathview/util/getntpstatus.py -v

 

Look for an error similar to the one below:

 

ntpquery.getntpstatus: Apr 06 2023 21:18:27 [INFO] Querying servers: ['216.218.192.202', '132.163.4.103', '129.6.15.28', '209.51.161.238', '129.69.1.153', '193.67.79.202', '150.101.254.110', '223.255.185.2', '200.20.186.76']

Actual Fix:

Allow Inbound/Outbound Traffic on Port 123 (UDP)
