Re: [CentOS] how to set ntpd listen only 127.0.0.1 ?

Thanks for your kind answer.

Look into the "restrict" commands in ntp.conf to implement security policies on NTP. You can find information on how it works on "man ntp_acc".

The default restrict config likes below.

restrict default nomodify notrap noquery

If I setup ntpd service as a client not server, above options are sufficient?

I would like to deny any ntpd query packets except reply packets from others because of client.

but it seems that other clients can query the date.

Thanks in advance.
