<code>ntpsweep</code>
prints per host the NTP stratum level, the clock offset in seconds, the daemon
version, the operating system and the processor. Optionally recursing through
all peers.
<p>This section was generated by <strong>AutoGen</strong>,
using the <code>agtexi-cmd</code> template and the option descriptions for the <code>ntpsweep</code> program.

This is the automatically generated usage text for ntpsweep.
<p>The text printed is the same whether selected with the <code>help</code> option
(<span class="option">--help</span>) or the <code>more-help</code> option (<span class="option">--more-help</span>). <code>more-help</code> will print
the usage text by passing it through a pager program.
<code>more-help</code> is disabled on platforms without a working
<code>fork(2)</code> function. The <code>PAGER</code> environment variable is
used to select the program, defaulting to <span class="file">more</span>. Both will exit
with a status code of 0.
<pre class="example">ntpsweep - Print various informations about given ntp servers - Ver. 4.2.8p8
