     71          1.1  christos 
     72          1.1  christos <p>The <code>ntpq</code> utility program is used to monitor NTP daemon <code>ntpd</code> operations and determine performance. 
     73          1.1  christos It uses the standard NTP mode 6 control message formats defined in
     74          1.1  christos Appendix B of the NTPv3 specification RFC1305. 
     75          1.1  christos The same formats are used in NTPv4, although some of the variable names have changed and new ones added. 
     76          1.1  christos The description on this page is for the NTPv4 variables.
     77          1.1  christos 
     78          1.1  christos   <p>The program can be run either in interactive mode or controlled using command line arguments.  Requests to read and write arbitrary variables can be assembled, with raw and pretty-printed output options being available.  The <code>ntpq</code> can also obtain and print a list of peers in a common format by sending multiple queries to the server.
     79          1.1  christos 
     80          1.1  christos   <p>If one or more request options is included on the command line when <code>ntpq</code> is executed, each of the requests will be sent to the NTP servers running on each of the hosts given as command line arguments, or on localhost by default.  If no request options are given, <code>ntpq</code> will attempt to read commands from the standard input and execute these on the NTP server running on the first host given on the command line, again defaulting to localhost when no other host is specified.  <code>ntpq</code> will prompt for commands if the standard input is a terminal device.
     81          1.1  christos 
     82          1.1  christos   <p><code>ntpq</code> uses NTP mode 6 packets to communicate with the NTP server, and hence can be used to query any compatible server on the network which permits it.  Note that since NTP is a UDP protocol this communication will be somewhat unreliable, especially over large distances in terms of network topology.  <code>ntpq</code> makes one attempt to retransmit requests, and will time requests out if the remote host is not heard from within a suitable timeout time.
     83          1.1  christos 
     84          1.1  christos   <p>Note that in contexts where a host name is expected, a <code>-4</code> qualifier preceding the host name forces DNS resolution to the IPv4 namespace, while a <code>-6</code> qualifier forces DNS resolution to the IPv6 namespace.
     85          1.1  christos

   1107          1.1  christos <p>Interactive format commands consist of a keyword followed by zero to four arguments.  Only enough characters of the full keyword to uniquely identify the command need be typed.  The output of a command is normally sent to the standard output, but optionally the output of individual commands may be sent to a file by appending a <code>&gt;</code>, followed by a file name, to the command line.  A number of interactive format commands are executed entirely within the <code>ntpq</code> program itself and do not result in NTP mode-6 requests being sent to a server.  These are described following.
