oscillator to stratum 8 in order to allow the two systems to use a lower
stratum server (7 or lower) if one is available. By default, the system uses
this drift file: /etc/ntp/drift.
3 On the voipbox2 system, create the /etc/ntp.conf file.
4 Edit the file and add these lines:
server 127.127.1.1
peer voipbox1
5 On the voipbox1 server, su to root and execute these commands:
/etc/init.d/ntpd stop
/etc/init.d/ntpd start
6 On the voipbox2 server, su to root and execute the same commands:
/etc/init.d/ntpd stop
/etc/init.d/ntpd start
Optionally, you can add any number of additional server entries in the
ntp.conf file.
Verification To verify that the NTP service is properly configured, run this command:
ntpq -p
Any user can run the ntpq command.
The output from this command shows the state of all of the ntp
servers with which the local system is communicating.
