It is essentially a stripped-down, caching-only name - server that answers queries using the BIND 9 lightweight - resolver protocol rather than the DNS protocol. - </p> -<p><span><strong class="command">lwresd</strong></span> - listens for resolver queries on a - UDP port on the IPv4 loopback interface, 127.0.0.1. This - means that <span><strong class="command">lwresd</strong></span> can only be used by - processes running on the local machine. By default, UDP port - number 921 is used for lightweight resolver requests and - responses. - </p> -<p> - Incoming lightweight resolver requests are decoded by the - server which then resolves them using the DNS protocol. When - the DNS lookup completes, <span><strong class="command">lwresd</strong></span> encodes - the answers in the lightweight resolver format and returns - them to the client that made the request. - </p> -<p> - If <code class="filename">/etc/resolv.conf</code> contains any - <code class="option">nameserver</code> entries, <span><strong class="command">lwresd</strong></span> - sends recursive DNS queries to those servers. This is similar - to the use of forwarders in a caching name server. If no - <code class="option">nameserver</code> entries are present, or if - forwarding fails, <span><strong class="command">lwresd</strong></span> resolves the - queries autonomously starting at the root name servers, using - a built-in list of root server hints. - </p> -</div> -<div class="refsect1" lang="en"> -<a name="id2543516"></a><h2>OPTIONS</h2> -<div class="variablelist"><dl> -<dt><span class="term">-4</span></dt> -<dd><p> - Use IPv4 only even if the host machine is capable of IPv6. - <code class="option">-4</code> and <code class="option">-6</code> are mutually - exclusive. - </p></dd> -<dt><span class="term">-6</span></dt> -<dd><p> - Use IPv6 only even if the host machine is capable of IPv4. - <code class="option">-4</code> and <code class="option">-6</code> are mutually - exclusive. - </p></dd> -<dt><span class="term">-c <em class="replaceable"><code>config-file</code></em></span></dt> -<dd><p> - Use <em class="replaceable"><code>config-file</code></em> as the - configuration file instead of the default, - <code class="filename">/etc/lwresd.conf</code>. - - <code class="option">-c</code> can not be used with <code class="option">-C</code>. - </p></dd> -<dt><span class="term">-C <em class="replaceable"><code>config-file</code></em></span></dt> -<dd><p> - Use <em class="replaceable"><code>config-file</code></em> as the - configuration file instead of the default, - <code class="filename">/etc/resolv.conf</code>. - <code class="option">-C</code> can not be used with <code class="option">-c</code>. - </p></dd> -<dt><span class="term">-d <em class="replaceable"><code>debug-level</code></em></span></dt> -<dd><p> - Set the daemon's debug level to <em class="replaceable"><code>debug-level</code></em>. - Debugging traces from <span><strong class="command">lwresd</strong></span> become - more verbose as the debug level increases. - </p></dd> -<dt><span class="term">-f</span></dt> -<dd><p> - Run the server in the foreground (i.e. do not daemonize). - </p></dd> -<dt><span class="term">-g</span></dt> -<dd><p> - Run the server in the foreground and force all logging - to <code class="filename">stderr</code>. - </p></dd> -<dt><span class="term">-i <em class="replaceable"><code>pid-file</code></em></span></dt> -<dd><p> - Use <em class="replaceable"><code>pid-file</code></em> as the - PID file instead of the default, - <code class="filename">/var/run/lwresd/lwresd.pid</code>. - </p></dd> -<dt><span class="term">-m <em class="replaceable"><code>flag</code></em></span></dt> -<dd><p> - Turn on memory usage debugging flags.
