If configuration file looks like below, is it ok or just need to add mentioned three lines from previous post?

server ip_address

restrict -6 default kod nomodify notrap nopeer noquery

restrict :: default kod nomodify notrap nopeer noquery

restrict default kod nomodify notrap nopeer noquery

disable monitor

We've modify ntp.conf file configuration as below:

server ip_address

restrict -6 default nomodify notrap noquery

restrict :: default nomodify notrap noquery

restrict default nomodify notrap noquery

disable monitor

After restart ntpd service and wait for long period, get following error message. Please advise.

#ntpq -pn

127.0.0.1: timed out, nothing received

***Requested timed out

Dear Concern,

Plese be noted, this host acts as a NTP client and doesn’t provide a public time service. Please suggest.
