NAME
       chronyc - command-line interface for chronyd


SYNOPSIS
       chronyc [OPTIONS]


DESCRIPTION
       chrony is a pair of programs for maintaining the accuracy of computer clocks.

       chronyc  is  a command-line interface program which can be used to monitor chronyd's performance and to change
       various operating parameters whilst it is running.


USAGE
       A detailed description of all commands supported by chronyc is available via the documentation  supplied  with
       the distribution (chrony.txt and chrony.texi).


OPTIONS
       A summary of the options supported by chronyc is included below.


       -h hostname
              specify hostname (default 127.0.0.1)

       -p port-number
              specify port-number

       -n     display raw IP addresses (don't attempt to look up hostnames)

       -4     resolve hostnames only to IPv4 addresses

       -6     resolve hostnames only to IPv6 addresses

       -m     allow  multiple  commands  to be specified on the command line.  Each argument will be interpreted as a
              whole command.

       -f conf-file
              This option can be  used  to  specify  an  alternate  location  for  the  configuration  file  (default
              /etc/chrony.conf). The configuration file is needed for the -a option.

       -a     With  this  option chronyc will try to authenticate automatically on start. It will read the configura‐
              tion file, read the command key from the keyfile and run the authhash and password commands.

       command
              specify command.  If no command is given, chronyc will read commands interactively.
