14.2.2. Understanding chronyc

The chrony daemon, chronyd, can be controlled by the command line utility chronyc. This utility provides a command prompt which allows entering of a number of commands to make changes to chronyd. The default configuration is for chronyd to only accept commands from a local instance of chronyc, but chronyc can be used to alter the configuration so that chronyd will allow external control. chronyc can be run remotely after first configuring chronyd to accept remote connections. The IP addresses allowed to connect to chronyd should be tightly controlled.
