Network Time Protocolhas been developed to keep computers synchronized. All computers are prone todrift and accurate timing is essential for many time critical applications.A version of NTP isinstalled on most versions of Windows (although a stripped down version calledSNTP Simplified NTP- is in older versions) and Linux but is free to downloadfrom NTP.org.When synchronising aa network it is preferable to use a dedicated NTP server that receives a timingsource from an atomic clock either via specialist radio transmissions or theGPS network. However, many Internet time references are available, some morereliable than others, although it must be noted Internet based time sources cantbe authenticated by NTP, leaving your computer vulnerable to threats.NTP is hierarchical andarranged into stratum. Stratum 0 is timing reference, while stratum 1 is aserver connected to a stratum 0 timing source and a stratum 2 is a computer (ordevice) attached to a stratum 1 server.The Basicconfiguration of NTP is done using the /etc/ntp.conf file you have to edit itand place the IP address of stratum 1 and stratum 2 servers. Here is an exampleof a basic ntp.conf file:server xxx.yyy.zzz.aaa prefer (time server addresssuch as time.windows.com)server 123.123.1.0server 122.123.1.0stratum 3Driftfile /etc/ntp/driftThe most basicntp.conf file will list 2 servers, one that it wishes to synchronise too and anIP address for itself. It is good housekeeping to have more than one server forreference in case one goes down. A server with the tagprefer is used for a trusted source ensuring NTP will always use that serverwhen possible. The IP address will be used in case of problems when NTP willsynchonise with itself is. The drift file is where NTP builds a record of the systemclock's drift rate and automatically adjusts for it.NTP will adjust yoursystem time but only slowly. NTP will await at least ten packets of informationbefore trusting the time source. To test NTP simply change your system clock byhalf an hour at the end of the day and the time in the morning should becorrect.
