What is NTP and how it works?

How does NTP work? Superficially, NTP is a software daemon operating in a client mode, server mode, or both. The purpose of NTP is to reveal the offset of the client’s local clock relative to a time server’s local clock. The client sends a time request packet (UDP) to the server which is time stamped and returned.

Ubuntu ọ na-eji NTP?

Until recently, most network time synchronization was handled by the Network Time Protocol daemon or ntpd. This server connects to a pool of other NTP servers that provide it with constant and accurate time updates. Ubuntu’s default install now uses timesyncd instead of ntpd.

Having synchronized clocks is not only convenient but required for many distributed applications. Therefore the firewall policy must allow the NTP service if the time comes from an external server.
