DESCRIPTION
ntpctl is a command-line utility designed to interact with the ntpd (Network Time Protocol daemon).
It serves as a client program, enabling users to query the ntpd daemon for status information, control its operation, and monitor its behavior.
ntpctl provides a convenient way to retrieve information about the current time synchronization status, peer information, and other relevant details managed by ntpd. Using ntpctl, administrators can diagnose and troubleshoot time synchronization issues, verify the accuracy of the system clock, and manage the ntpd service.
The tool offers functionalities such as listing peers, monitoring clock offset, and querying variables. It provides a more user-friendly interface than directly interacting with ntpd's control interface.
EXIT STATUS
The ntpctl command exits with a status of 0 on success and 1 on failure.
It also exits with a status of 2 if an invalid command-line option is specified.
