    <title>Description</title>

    <para>The shorewall6-lite utility is used to control the Shoreline
    Firewall Lite (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_shorewall.htm#Trace">http://www.shorewall.net/starting_and_stopping_shorewall.htm#Trace</ulink>.</para>

    <para>The nolock <option>option</option> prevents the command from
    attempting to acquire the shorewall6-lite lockfile. It is useful if you
    need to include <command>shorewall</command> commands in
    <filename>/etc/shorewall/started</filename>.</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">shorewall6.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. Alternately, <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 host or network addresses.<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>shorewall6-lite 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
          shorewall6-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>

          <para>If <option>-f</option> is given, the command will be processed
          by the compiled script that executed the last successful <emphasis
          role="bold">start</emphasis>, <emphasis
          role="bold">restart</emphasis> or <emphasis
          role="bold">refresh</emphasis> command if that script exists.</para>
        </listitem>
      </varlistentry>

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

        <listitem>
          <para>The delete command reverses the effect of an earlier <emphasis
          role="bold">add</emphasis> command.</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.</para>
        </listitem>
      </varlistentry>

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

        <listitem>
          <para>Added in Shorewall 4.4.26. Disables the optional provider
          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>

        <listitem>
          <para>Produces a verbose report about the firewall configuration for
          the purpose of problem analysis.</para>

          <para>The <emphasis role="bold">-x</emphasis> option causes actual
          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 shorewall6-lite log
          messages to be displayed.</para>

          <para>The <emphasis role="bold">-l</emphasis> option causes the rule
          number for each Netfilter rule to be displayed.</para>
        </listitem>
