NTP Overview. NTP is designed to synchronize the time on a network of machines. NTP runs over the User Datagram Protocol (UDP), with port 123 as both the source and destination, which in turn runs over IP. NTP Version 3 RFC 1305 is used to synchronize timekeeping among a set of distributed time servers and clients.

The default location for the file is /etc/ntp.conf and you can view the file by entering the following command:

ntpq uses NTP mode 6 packets to communicate with the NTP server, and hence can be used to query any compatible server on the network which permits it. Note that since NTP is a UDP protocol this communication will be somewhat unreliable, especially over large distances in terms of network topology.2.
