Chapter 16<P> Configuring the Network Time Protocol (NTP) Configuring the Network Time Protocol (NTP)

Use NTP, the Network Time Protocol, to synchronize clocks on networks with Internet access. You can, alternately, use the Time Synchronization Protocol (TSP) to synchronize clocks. For information on the differences between TSP and NTP, see ``Distributed time services''.

In this implementation of NTP, the xntpd(ADMN) time daemon runs on each host on your network. These daemons communicate with each other using a hierarchical scheme in which servers on the Internet pass time data to additional servers and clients throughout the Internet.

The remainder of this chapter covers how NTP works, an NTP glossary, guidelines for using NTP, several examples of using NTP, descriptions of NTP files, and ways to test and troubleshoot NTP.
