    <title>Description</title>

    <para>The shorewall-lite utility is used to control the Shoreline Firewall
    (Shorewall) Lite.</para>
  </refsect1>

  <refsect1>
    <title>Options</title>

    <para>The <option>trace</option> and <option>debug</option> options are
    used for debugging. See <ulink
    url="http://www.shorewall.net/starting_and_stopping.htm#Trace">http://www.shorewall.net/starting_and_stopping.htm#Trace</ulink>.</para>

    <para>The nolock <option>option</option> prevents the command from
    attempting to acquire the Shorewall Lite lockfile. It is useful if you
    need to include <command>shorewall-lite</command> commands in the
    <filename>started</filename> extension script.</para>

    <para>The <emphasis>options</emphasis> control the amount of output that
    the command produces. They consist of a sequence of the letters <emphasis
    role="bold">v</emphasis> and <emphasis role="bold">q</emphasis>. If the
    options are omitted, the amount of output is determined by the setting of
    the VERBOSITY parameter in <ulink
    url="shorewall.conf.html">shorewall.conf</ulink>(5). Each <emphasis
    role="bold">v</emphasis> adds one to the effective verbosity and each
    <emphasis role="bold">q</emphasis> subtracts one from the effective
    VERBOSITY. Anternately, <emphasis role="bold">v</emphasis> may be followed
    immediately with one of -1,0,1,2 to specify a specify VERBOSITY. There may
    be no white space between <emphasis role="bold">v</emphasis> and the
    VERBOSITY.</para>

    <para>The <emphasis>options</emphasis> may also include the letter
    <option>t</option> which causes all progress messages to be
    timestamped.</para>
  </refsect1>

  <refsect1>
    <title>Commands</title>

    <para>The available commands are listed below.</para>

    <variablelist>
      <varlistentry>
        <term><emphasis role="bold">add</emphasis></term>

        <listitem>
          <para>Adds a list of hosts or subnets to a dynamic zone usually used
          with VPN's.</para>

          <para>The <emphasis>interface</emphasis> argument names an interface
          defined in the <ulink
          url="shorewall-interfaces.html">shorewall-interfaces</ulink>(5)
          file. A <emphasis>host-list</emphasis> is comma-separated list whose
          elements are a host or network address.<caution>
              <para>The <command>add</command> command is not very robust. If
              there are errors in the <replaceable>host-list</replaceable>,
              you may see a large number of error messages yet a subsequent
              <command>shorewall show zones</command> command will indicate
              that all hosts were added. If this happens, replace
              <command>add</command> by <command>delete</command> and run the
              same command again. Then enter the correct command.</para>
            </caution></para>
        </listitem>
      </varlistentry>

      <varlistentry>
        <term><emphasis role="bold">allow</emphasis></term>

        <listitem>
          <para>Re-enables receipt of packets from hosts previously
          blacklisted by a <emphasis role="bold">drop</emphasis>, <emphasis
          role="bold">logdrop</emphasis>, <emphasis
          role="bold">reject</emphasis>, or <emphasis
          role="bold">logreject</emphasis> command.</para>
        </listitem>
      </varlistentry>

      <varlistentry>
        <term><emphasis role="bold">clear</emphasis></term>

        <listitem>
          <para>Clear will remove all rules and chains installed by Shorewall
          Lite. The firewall is then wide open and unprotected. Existing
          connections are untouched. Clear is often used to see if the
          firewall is causing connection problems.</para>
        </listitem>
      </varlistentry>

      <varlistentry>
        <term><emphasis role="bold">delete</emphasis></term>

          role="bold">add</emphasis> command.</para>

          defined in the <ulink
          url="shorewall-interfaces.html">shorewall-interfaces</ulink>(5)
          file. A <emphasis>host-list</emphasis> is comma-separated list whose

        <term><emphasis role="bold">disable</emphasis></term>

        <listitem>

          associated with the specified <replaceable>interface</replaceable>
          or <replaceable>provider</replaceable>. Where more than one provider
          share a single network interface, a
          <replaceable>provider</replaceable> name must be given.</para>

      <varlistentry>
        <term><emphasis role="bold">drop</emphasis></term>

          packet and byte counts to be displayed. Without that option, these
          counts are abbreviated. The <emphasis role="bold">-m</emphasis>
          option causes any MAC addresses included in Shorewall Lite log
          messages to be displayed.</para>
        </listitem>

      <varlistentry>

          produces an audible alarm when new Shorewall Lite messages are
          logged. The <emphasis role="bold">-m</emphasis> option causes the
          MAC address of each packet source to be displayed if that
          information is available. The
          <replaceable>refresh-interval</replaceable> specifies the time in
