<title>Description</title>
<para>The shorewall utility is used to control the Shoreline Firewall
(Shorewall).</para>
</refsect1>
<refsect1>
<title>Options</title>
<para>The <option>trace</option> and <option>debug</option> options are
used for debugging. See <ulink
url="/starting_and_stopping_shorewall.htm#Trace">http://www.shorewall.net/starting_and_stopping_shorewall.htm#Trace</ulink>.</para>
<para>The <option>nolock</option> option prevents the command from
attempting to acquire the Shorewall 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="/manpages/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. Alternatively, <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>{
<replaceable>interface</replaceable>[:<replaceable>host-list</replaceable>]...
<replaceable>zone</replaceable> | <replaceable>zone</replaceable>
<replaceable>host-list</replaceable> }</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="/manpages/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>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>
<para>Beginning with Shorewall 4.5.9, the <emphasis
role="bold">dynamic_shared</emphasis> zone option (<ulink
url="/manpages/shorewall-zones.html">shorewall-zones</ulink>(5))
allows a single ipset to handle entries for multiple interfaces.
When that option is specified for a zone, the <command>add</command>
command has the alternative syntax in which the
<replaceable>zone</replaceable> name precedes the
<replaceable>host-list</replaceable>.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">allow</emphasis>

<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>

[-<option>d</option>] [-<option>p</option>] [-<option>r</option>]

[<replaceable>directory</replaceable>]</term>
<listitem>
<para>Compiles the configuration in the specified
<emphasis>directory</emphasis> and discards the compiled output
script. If no <emphasis>directory</emphasis> is given, then
/etc/shorewall is assumed.</para>
