NAME

ntpdc - vendor-specific NTP query program

SYNOPSIS

ntpdc
[ host ...]

DESCRIPTION

This manual page documents, briefly, the nnttppddcc 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 is a member of the ipv4 class of options.

Force DNS resolution of following host names on the command line to the IPv4 namespace.
-6, --ipv6
Force IPv6 DNS name resolution. This option is a member of the ipv4 class of options.

Force DNS resolution of following host names on the command line to the IPv6 namespace.
-c _c_m_d, --command=_c_m_d
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 _s_t_r_i_n_g, --set-debug-level=_s_t_r_i_n_g
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 usage information and exit.
-!,--more-help
Extended usage information passed thru pager.
-> [_r_c_f_i_l_e], --save-opts[=_r_c_f_i_l_e]
Save the option state to _r_c_f_i_l_e. The default is the _l_a_s_t configuration file listed in the OOPPTTIIOONN PPRREESSEETTSS section, below.
-< _r_c_f_i_l_e, --load-opts=_r_c_f_i_l_e,--no-load-opts
Load options from _r_c_f_i_l_e. The _n_o_-_l_o_a_d_-_o_p_t_s form will disable the loading of earlier RC/INI files. _-_-_n_o_-_l_o_a_d_-_o_p_t_s is handled early, out of order.
-v [{_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 _n_o_t _p_r_e_s_e_t_t_a_b_l_e may be preset by loading values from configuration ("RC" or ".INI") file(s) and values from environment variables named:
          NNTTPPDDCC__<> or NNTTPPDDCC
        
The environmental presets take precedence (are processed later than) the configuration files. The _h_o_m_e_r_c files are "_$_H_O_M_E", and "_.". If any of these are directories, then the file _._n_t_p_r_c is searched for within those directories.
