Ntp Port Port 123 is a networking port used for the Network Time Protocol NTP It is registered with the Internet Assigned Numbers Authority IANA as a standard port assignment for NTP
When troubleshooting unknown open ports it is useful to find exactly what services processes are listening to them This can be accomplished in both Windows command prompt and Linux variants What is NTP Port The NTP Port is used by the Network Time Protocol NTP which synchronizes clocks across devices in a network Accurate time synchronization is critical for logging

NTP servers typically listen on UDP port 123 for requests and respond from the same port which is also true for the built in W32Time NTP server You can enable or disable the built in What is the NTP port NTP or Network Time Protocol synchronizes clocks across servers workstations network devices databases logs and distributed systems Standard NTP uses UDP
The NTP protocol only uses UDP for its work and UDP is an appropriate protocol for time synchronization However there are other needs for NTP including monitoring and control and Ntp server to server communication is source and destination port 123 It is most convenient to explicitly allow that at least to the hosts on which you are running a ntp service

Network Time Protocol NTP is an application layer protocol that synchronizes the clocks of computers across a network Developed by David Mills in 1981 it ensures accurate and consistent As previously mentioned What Port Does NTP Use The answer is that NTP relies primarily on UDP port 123 for its communication UDP User Datagram Protocol is a connectionless
