NTPDC(1)                                     Programmer's Manual                                    NTPDC(1)



NAME
       ntpdc - vendor-specific NTP query program

SYNOPSIS
       ntpdc [-flag [value]]... [--opt-name [[=| ]value]]...
               [ host ...]

DESCRIPTION
       This manual page briefly documents the ntpdc command.  The [= prog-name =] utility program is used to
       query an NTP daemon about its current state and to request changes in that state.  It uses NTP mode 7
       control  message  formats described in the source code.  The program may be run either in interactive
       mode or controlled using command line arguments.   Extensive  state  and  statistics  information  is
       available  through  the [= prog-name =] interface.  In addition, nearly all the configuration options
       which can be specified at startup using ntpd's configuration file may also be specified at  run  time
       using [= prog-name =] .



OPTIONS
       -4, --ipv4
              Force  IPv4  DNS  name resolution.  This option must not appear in combination with any of the
              following options: ipv6.

              Force DNS resolution of following host names on the command line to the IPv4 namespace.

       -6, --ipv6
              Force IPv6 DNS name resolution.  This option must not appear in combination with  any  of  the
              following options: ipv4.

              Force DNS resolution of following host names on the command line to the IPv6 namespace.

       -c cmd, --command=cmd
              run a command and exit.  This option may appear an unlimited number of times.

              The  following  argument  is  interpreted as an interactive format command and is added to the
              list of commands to be executed on the specified host(s).

       -l, --listpeers
              Print a list of the peers.  This option must not appear in combination with any of the follow-ing following
              ing options: command.

              Print  a  list  of  the peers known to the server as well as a summary of their state. This is
              equivalent to the 'listpeers' interactive command.

       -p, --peers
              Print a list of the peers.  This option must not appear in combination with any of the follow-ing following
              ing options: command.

              Print  a  list  of  the peers known to the server as well as a summary of their state. This is
              equivalent to the 'peers' interactive command.

       -s, --showpeers
              Show a list of the peers.  This option must not appear in combination with any of the  follow-ing following
              ing options: command.

              Print  a  list  of  the peers known to the server as well as a summary of their state. This is
              equivalent to the 'dmpeers' interactive command.

       -i, --interactive
              Force ntpq to operate in interactive mode.  This option must not appear  in  combination  with
              any of the following options: command, listpeers, peers, showpeers.

              Force ntpq to operate in interactive mode.  Prompts will be written to the standard output and
              commands read from the standard input.

       -d, --debug-level
              Increase output debug message level.  This option may appear an unlimited number of times.

              Increase the debugging message output level.

       -D string, --set-debug-level=string
              Set the output debug message level.  This option may appear an unlimited number of times.

              Set the output debugging level.  Can be supplied multiple times, but each overrides the previ-ous previous
              ous value(s).

       -n, --numeric
              numeric host addresses.

              Output  all host addresses in dotted-quad numeric format rather than converting to the canoni-cal canonical
              cal host names.

       -?, --help
              Display extended usage information and exit.

       -!, --more-help
              Extended usage information passed thru pager.

       -> [rcfile], --save-opts[=rcfile]
              Save the option state to rcfile.  The default is the last configuration  file  listed  in  the
              OPTION PRESETS section, below.

       -< rcfile, --load-opts=rcfile, --no-load-opts
              Load  options  from  rcfile.  The no-load-opts form will disable the loading of earlier RC/INI
              files.  --no-load-opts is handled early, out of order.

       - [{v|c|n}], --version[={v|c|n}]
              Output version of program and exit.  The default mode is `v', a simple version.  The `c'  mode
              will print copyright information and `n' will print the full copyright notice.

OPTION PRESETS
       Any  option  that is not marked as not presettable may be preset by loading values from configuration
       ("RC" or ".INI") file(s) and values from environment variables named:
         NTPDC_<option-name> or NTPDC
       The environmental presets take precedence (are processed later than) the  configuration  files.   The
       homerc files are "$HOME", and ".".  If any of these are directories, then the file .ntprc is searched
       for within those directories.
