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.Checking the status of NTP with ntpq command. The ntpq utility program is used to monitor NTP daemon ntpd operations and determine performance. The program can be run either in interactive mode or controlled using command line arguments. Type the following command on your Linux or Unix-based system: $ ntpq -pn.

Network Time Protocol (NTP) is a protocol used to synchronize computer clock times in a network . It belongs to and is one of the oldest parts of the TCP/IP protocol suite. The term NTP applies to both the protocol and the client-server programs that run on computers.

Use the debug ip packet command in order to check if NTP packets are received and sent. Since debug output can be chatty, you can limit debug output with the use of Access Control Lists (ACLs).

Network Time Protocol (NTP) NTP is used to synchronize the clock of a network client with a server. It's the primary work of David L. Mills, PhD. The NTP server will (hopefully) have the precise time (probably directly from an atomic clock). The NTP client asks the NTP server about the current time, and then will adjust it's internal clock to ...
