Environment

VMware vCenter Server 7.x

VMware vCenter Server 8.x

Cause

Space issue in the NTP configuration file after server detail caused the script to enter a loop and exit with out of range error 

 

Resolution

To resolve the VDT script parsing error, we need to edit the /etc/ntp.conf file by removing extraneous content, such as empty lines or trailing whitespace.

Please follow these steps:

1. Backup the configuration file: cp /etc/ntp.conf /etc/ntp.conf_bak

2. Edit the file: Open the file using vi /etc/ntp.conf and remove any extra spaces or empty lines.

3. Verify: Ensure the final output matches the expected configuration format shown below.
