NTPDC(1) Programmer's Manual NTPDC(1)NAMEntpdc - vendor-specific NTP query program
SYNOPSISntpdc [-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

the specified host(s).
-l, --listpeers
Print a list of the peers. This option must not appear in com‐
bination with any of the following options: command.
Print a list of the peers known to the server as well as a sum‐
mary 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 com‐
bination with any of the following options: command.
Print a list of the peers known to the server as well as a sum‐
mary of their state. This is equivalent to the 'peers' interac‐

-s, --showpeers
Show a list of the peers. This option must not appear in combi‐
nation with any of the following options: command.
Print a list of the peers known to the server as well as a sum‐
mary of their state. This is equivalent to the 'dmpeers' inter‐
active command.
-i, --interactive

appear in combination with any of the following options: com‐
mand, listpeers, peers, showpeers.
Force ntpq to operate in interactive mode. Prompts will be

dard 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 con‐
figuration 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 load‐
ing 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.
