<title>Description</title>
<para>The shorewall-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 Shorewall-lite lockfile. It is useful if you
need to include <command>shorewall</command> commands in the
<filename>started</filename> <ulink
url="../shorewall_extension_scripts.html">extension script</ulink>.</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. Alternately, <emphasis role="bold">v</emphasis> may be followed
immediately with one of -1,0,1,2 to 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="shorewall-interfaces.html">shorewall-interfaces</ulink>(5)
file. A <emphasis>host-list</emphasis> is comma-separated list whose
elements are host or network addresses.</para>
<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-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>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">allow
</emphasis><replaceable>address</replaceable></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. Beginning with Shorewall
5.0.10, this command can also re-enable addresses blacklisted using
the <command>blacklist</command> command.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">blacklist</emphasis>
<replaceable>address</replaceable> [ <replaceable>option</replaceable>
... ]</term>
<listitem>
<para>Added in Shorewall 5.0.8 and requires
DYNAMIC_BLACKLIST=ipset.. in <ulink
url="/manpages/shorewall.conf.html">shorewall.conf</ulink>(5).
Causes packets from the given host or network
<replaceable>address</replaceable> to be dropped, based on the
setting of BLACKLIST in <ulink
url="/manpages/shorewall.conf.html">shorewall.conf</ulink>(5). The
<replaceable>address</replaceable> along with any
<replaceable>option</replaceable>s are passed to the <command>ipset
add</command> command.</para>
<para>If the <option>disconnect</option> option is specified in the
DYNAMIC_BLACKLISTING setting, then the effective VERBOSITY
determines the amount of information displayed:</para>
<itemizedlist>
<listitem>
<para>If the effective verbosity is &gt; 0, then a message
giving the number of conntrack flows deleted by the command is
displayed.</para>
</listitem>
<listitem>
<para>If the effective verbosity is &gt; 1, then the conntrack
table entries deleted by the command are also displayed.</para>
</listitem>
</itemizedlist>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">call <replaceable>function</replaceable> [
<replaceable>parameter</replaceable> ... ]</emphasis></term>

<para>Added in Shorewall 4.6.10. Allows you to call a function in
one of the Shorewall libraries or in your compiled script. function
must name the shell function to be called. The listed parameters are
passed to the function.</para>
<para>The function is first searched for in
<filename>lib.base</filename>, <filename>lib.common</filename> and
<filename>lib.cli</filename>. If it is not found, the call command
is passed to the generated script to be executed.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">clear
</emphasis>[-<option>f</option>]</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>
<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">reload</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">close</emphasis> {
<replaceable>open-number</replaceable> |
<replaceable>source</replaceable> <replaceable>dest</replaceable> [
<replaceable>protocol</replaceable> [ <replaceable>port</replaceable>
] ] }</term>
<listitem>
<para>Added in Shorewall 4.5.8. This command closes a temporary open
created by the <command>open</command> command. In the first form,
an <replaceable>open-number</replaceable> specifies the open to be
closed. Open numbers are displayed in the <emphasis
role="bold">num</emphasis> column of the output of the
<command>shorewall-lite show opens </command>command.</para>

<replaceable>interface</replaceable>[:<replaceable>host-list</replaceable>]...
<replaceable>zone</replaceable> | <replaceable>zone</replaceable>
<replaceable>host-list</replaceable> }</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>{
<replaceable>interface</replaceable> |
<replaceable>provider</replaceable> }</term>
<listitem>
<para>Added in Shorewall 4.4.26. Disables the optional provider
associated with the specified <replaceable>interface</replaceable>
