<p>Please read <i class="term"><a href="../modules/nns/nns_intro.html">Name service facility, introduction</a></i> first.</p>
<p>The application described by this document, <b class="syscmd"><a href="nns.html">nns</a></b>, is a simple
command line server for the nano name service facility provided by the
Tcllib packages <b class="package"><a href="../modules/nns/nns_client.html">nameserv</a></b>, and <b class="package"><a href="../modules/nns/nns_server.html">nameserv::server</a></b>.
Beyond that the application's sources also serve as an example of how
to use the server package <b class="package"><a href="../modules/nns/nns_server.html">nameserv::server</a></b>.</p>
<p>This name service facility has nothing to do with the Internet's
<i class="term">Domain Name System</i>, otherwise known as <i class="term"><a href="../../../index.html#key601">DNS</a></i>. If the
reader is looking for a package dealing with that please see either of
the packages <b class="package"><a href="../modules/dns/tcllib_dns.html">dns</a></b> and <b class="package">resolv</b>, both found in Tcllib
too.</p>
<div id="subsection1" class="doctools_subsection"><h3><a name="subsection1">USE CASES</a></h3>
<p><b class="syscmd">nnsd</b> was written with the following main use case in
mind.</p>
<ol class="doctools_enumerated">
<li><p>Run a nano name service on some host.</p></li>
</ol>
</div>
<div id="subsection2" class="doctools_subsection"><h3><a name="subsection2">COMMAND LINE</a></h3>

<dd><p>The command configures a server per the specified options and starts
it. The command will not exit on its own, as it keeps the name service
database wholly in memory. The user has to kill it explicitly, either
by sending a a signal, or through the job-control facilities of the
shell in use.</p>
<p>The options to configure the name service are explained in section
<span class="sectref"><a href="#subsection3">OPTIONS</a></span>.</p></dd>

</div>
<div id="subsection3" class="doctools_subsection"><h3><a name="subsection3">OPTIONS</a></h3>

application</p>
<dl class="doctools_options">
<dt><b class="option">-localonly</b> bool</dt>
<dd><p>If this option is not specified it defaults to <b class="const">true</b>, i.e.
acceptance of only local connections. The server will accept remote
connections, i.e. connections from other hosts, if and only if this
option is configured to <b class="const">false</b>.</p></dd>
<dt><b class="option">-port</b> number</dt>
<dd><p>If this option is not specified it defaults to <b class="const">38573</b>. It
specifies the TCP port the server has to listen on for requests.</p></dd>
