Redhat:NTS config
NTP Server Configuration
The ntp.conf file is also used to configure a Time server.
driftfile
The first directive is "driftfile". This defines the file used to monitor errors in the local system clock.
restrict
The "restict" directive can help protect the NTP server. By default it works on ipv4, but the -6 flag works on ipv6 networks.
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery
- restrict server
When all of these restrictions are combined they will not work for a Time Server.
Specifically a time server has to synchronize with peers. So obviously 'nopeers' should be removed.
To allow other systems to syncronise with your server 'noquery' should be revolved.
