Network Time Protocol (NTP) is a protocol designed to time-synchronize a network of machines. NTP runs on User Datagram Protocol (UDP), which in turn runs on IP. NTP Version 3 is documented in RFC 1305. This module describes how to configure Network Time Protocol on Ci...

A port is a logical construct that allows the routing of incoming messages to specific processes. There's a particular port for every type of IPS. A port is an unsigned 16-bit number in the range 0 to 65535, and is also known as a port number. Based on the communications protocol used...
Network Time Protocol Network Time Protocol (NTP) is a protocol designed to time-synchronize a network of machines. NTP runs on User Datagram Protocol (UDP), which in turn runs on IP. NTP Version 3 is documented in RFC 1305. NTP services are disabled on all interfaces by default. ...

protocol calledSNTP(Simple Network Time Protocol). SNTP uses the same TCP/IP packet structure like NTP but due to the simpler algorithms, it provides only very reduced precision. The NTP package contains a background program (daemonorservice) which synchronizes the computer's system time to one...
