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 configura-
       tion 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 following 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 following 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 following 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 previous value(s).

       -n, --numeric
	      numeric host addresses.

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