What is NTP configuration file?
conf file is a text file with configuration information for the NTP daemon, ntpd . On Unix-like systems it is commonly located in the /etc/ directory, on Windows system in the directory C:\Program files (x86)\NTP\etc\ or C:\Program files\NTP\etc\ .
Where is NTP config?
The ntp. conf configuration file is read at initial startup by the ntpd(8) daemon in order to specify the synchronization sources, modes, and other related information. Usually, it is installed in the /etc directory, but could be installed elsewhere (see the daemon’s -c command line option).

- restart the ntpd service :

Is chrony better than NTP?
Things chronyd can do better than ntpd are: chronyd can work well when external time references are only intermittently accessible, whereas ntpd needs regular polling of time reference to work well. chronyd can perform well even when the network is congested for longer periods of time.
What is Iburst in NTP?
The iburst option instructs ntpd to send an initial “burst” of time queries at startup. This results in a faster synchronization of the ntpd with its reference servers upon startup.
How do I know if my NTP is syncing?
The ntpstat command will report the synchronisation state of the NTP daemon running on the local machine….exit status of ntpstat command
- If exit status 0 – Clock is synchronised.
- exit status 1 – Clock is not synchronised.
- exit status 2 – If clock state is indeterminant, for example if ntpd is not contactable.
How long does NTP sync take?
Usually it takes about five minutes (five good samples) until a NTP server is accepted as synchronization source. Interestingly, this is also true for local reference clocks that have no delay at all by definition.
Which is version 4 of the Network Time Protocol ( NTP )?
It is a complete implementation of the Network Time Protocol (NTP) version 4, as defined by RFC 5905, but also retains compatibility with version 3, as defined by RFC 1305, and versions 1 and 2, as defined by RFC 1059 and RFC 1119, respectively. The ntpd utility can synchronize time to a theoretical precision of about 232 picoseconds.
