Network Time Protocol (NTP)

General Information

Time is important on any system for automated jobs, log files, security, etc. This quick how to will get NTP up and running on a Linux server.


  • Distro(s): Enterprise Linux 6

The packages:

  • ntp - the ntp daemon service
  • ntpdate - a utility to run ad-hoc for time setting
  • ntp-doc - ntp documentation
yum install ntp ntpdate ntp-doc

chkconfig ntpd on


Visit and verify the current ntp servers.

They most likely are still (2015-01-07):

  • server
  • server
  • server
  • server

Add the above server lines to /etc/ntp.conf in place of the default servers.

vim /etc/ntp.conf

Finally, start the NTP daemon service.

/etc/init.d/ntpd start
