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 86 1.1
