@node ntpq Invocation @section Invoking ntpq @pindex ntpq @cindex standard NTP query program @ignore # # EDIT THIS FILE WITH CAUTION (ntpq-opts.texi) # # It has been AutoGen-ed Tuesday December 8, 2009 at 08:14:28 AM EST # From the definitions ntpq-opts.def # and the template file aginfo.tpl @end ignore This program has no explanation. The [= prog-name =] utility program is used to query NTP servers which implement the standard NTP mode 6 control message formats defined in Appendix B of the NTPv3 specification RFC1305, requesting information about current state and/or changes in that state. The same formats are used in NTPv4, although some of the variables have changed and new ones added. This section was generated by @strong{AutoGen}, the aginfo template and the option descriptions for the @command{ntpq} program. It documents the ntpq usage text and option meanings.

The following option preset mechanisms are supported: - reading file /users/stenn/.ntprc - reading file /deacon/backroom/snaps/ntp-stable/ntpq/.ntprc - examining environment variables named NTPQ_* The [= prog-name =] utility program is used to query NTP servers which implement the standard NTP mode 6 control message formats defined in Appendix B of the NTPv3 specification RFC1305, requesting information about current state and/or changes in that state.

This option has some usage constraints. It: @itemize @bullet @item is a member of the ipv4 class of options. @end itemize Force DNS resolution of following host names on the command line to the IPv4 namespace. @node ntpq ipv6 @subsection ipv6 option (-6) @cindex ntpq-ipv6 This is the ``force ipv6 dns name resolution'' option. This option has some usage constraints. It: @itemize @bullet @item is a member of the ipv4 class of options. @end itemize Force DNS resolution of following host names on the command line to the IPv6 namespace. @node ntpq command @subsection command option (-c) @cindex ntpq-command This is the ``run a command and exit'' option. This option has some usage constraints. It: @itemize @bullet @item may appear an unlimited number of times. @end itemize 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). @node ntpq debug-level @subsection debug-level option (-d) @cindex ntpq-debug-level This is the ``increase output debug message level'' option. This option has some usage constraints. It: @itemize @bullet @item may appear an unlimited number of times. @item must be compiled in by defining @code{DEBUG} during the compilation. @end itemize Increase the debugging message output level. @node ntpq set-debug-level @subsection set-debug-level option (-D) @cindex ntpq-set-debug-level This is the ``set the output debug message level'' option. This option has some usage constraints. It: @itemize @bullet @item may appear an unlimited number of times. @item must be compiled in by defining @code{DEBUG} during the compilation. @end itemize Set the output debugging level. Can be supplied multiple times, but each overrides the previous value(s). @node ntpq peers @subsection peers option (-p) @cindex ntpq-peers This is the ``print a list of the peers'' option. This option has some usage constraints. It: @itemize @bullet @item must not appear in combination with any of the following options: interactive. @end itemize 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. @node ntpq interactive @subsection interactive option (-i) @cindex ntpq-interactive This is the ``force ntpq to operate in interactive mode'' option. This option has some usage constraints. It: @itemize @bullet @item must not appear in combination with any of the following options: command, peers. @end itemize Force ntpq to operate in interactive mode. Prompts will be written to the standard output and commands read from the standard input. @node ntpq numeric @subsection numeric option (-n) @cindex ntpq-numeric This is the ``numeric host addresses'' option. Output all host addresses in dotted-quad numeric format rather than converting to the canonical host names.
