Dear Concern,

Current NTP configuration (/etc/ntp.conf) is as follow.

server ip_address

restrict -6 default kod nomodify notrap nopeer noquery

disable monitor

Edit /etc/ntp.conf file and add the below mentioned enteries

restrict -6 default nomodify notrap noquery

restrict :: default nomodify notrap noquery

restrict default nomodify notrap noquery

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.
