How to configure ntp in Linux

You just need to add the some ntp server in your /etc/ntp.conf and /etc/ntp/step-tickers

/etc/ntp.conf:

server 192.168.0.5
server 192.168.0.6

/etc/ntp/step-tickers

192.168.0.5
192.168.0.6

Then of course make sure that ntp will start at boot time:

chkconfig –level 2345 ntpd on
chkconfig –list ntpd

And let’s start the service now:
service ntpd start
