<title>Description</title>
<para>The shorewall6 utility is used to control the Shoreline Firewall 6
(Shorewall6).</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 lockfile. It is useful if you need to
include <command>shorewall6</command> commands in
<filename>/etc/shorewall6/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="shorewall6.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. 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></term>
<listitem>
<para>Added in Shorewall 4.4.21. 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="shorewall6-interfaces.html">shorewall6-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="shorewall6-zones.html">shorewall6-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></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">check</emphasis></term>
<listitem>
<para>Compiles the configuraton in the specified
<emphasis>directory</emphasis> and discards the compiled output
script. If no <emphasis>directory</emphasis> is given, then
/etc/shorewall6 is assumed.</para>
<para>The <emphasis role="bold">-e</emphasis> option causes the
compiler to look for a file named capabilities. This file is
produced using the command <emphasis role="bold">shorewall6-lite
show -f capabilities &gt; capabilities</emphasis> on a system with
Shorewall6 Lite installed.</para>
<para>The <option>-d</option> option causes the compiler to be run
under control of the Perl debugger.</para>
<para>The <option>-p</option> option causes the compiler to be
profiled via the Perl <option>-wd:DProf</option> command-line
option.</para>
<para>The <option>-r</option> option was added in Shorewall 4.5.2
and causes the compiler to print the generated ruleset to standard
out.</para>
<para>The <option>-T</option> option was added in Shorewall 4.4.20
and causes a Perl stack trace to be included with each
compiler-generated error and warning message.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">clear</emphasis></term>
<listitem>
<para>Clear will remove all rules and chains installed by
Shorewall6. 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">compile</emphasis></term>
<listitem>
<para>Compiles the current configuration into the executable file
<emphasis>pathname</emphasis>. If a directory is supplied,
Shorewall6 will look in that directory first for configuration
files. If the <emphasis>pathname</emphasis> is omitted, the file
firewall in the VARDIR (normally <filename
class="directory">/var/lib/shorewall/</filename>) is assumed. A
<emphasis>pathname</emphasis> of '-' causes the compiler to send the
generated script to it's standard output file. Note that '-v-1' is
usually specified in this case (e.g., <command>shorewall6 -v-1
compile -- -</command>) to suppress the 'Compiling...' message
normally generated by <filename>/sbin/shorewall6</filename>.</para>
<para>When -e is specified, the compilation is being performed on a
system other than where the compiled script will run. This option
disables certain configuration options that require the script to be
compiled where it is to be run. The use of -e requires the presense
of a configuration file named <filename>capabilities</filename>
which may be produced using the command <emphasis
role="bold">shorewall6-lite show -f capabilities &gt;
capabilities</emphasis> on a system with Shorewall6 Lite
installed</para>
<para>The <option>-d</option> option causes the compiler to be run
under control of the Perl debugger.</para>
<para>The <option>-p</option> option causes the compiler to be
profiled via the Perl <option>-wd:DProf</option> command-line
option.</para>
<para>The <option>-T</option> option was added in Shorewall 4.4.20
and causes a Perl stack trace to be included with each
compiler-generated error and warning message.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">delete</emphasis></term>
<listitem>
<para>Added in Shorewall 4.4.21. 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="shorewall6-interfaces.html">shorewall6-interfaces</ulink>(5)
file. A <emphasis>host-list</emphasis> is comma-separated list whose
elements are a host or network address.</para>
<para>Beginning with Shorewall 4.5.9, the <emphasis
role="bold">dynamic_shared</emphasis> zone option (<ulink
url="shorewall6-zones.html">shorewall6-zones</ulink>(5)) allows a
single ipset to handle entries for multiple interfaces. When that
option is specified for a zone, the <command>delete</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">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>
<para>Beginning with Shorewall 4.5.10, this command may be used with
any optional network interface. <replaceable>interface</replaceable>
may be either the logical or physical name of the interface. The
command removes any routes added from <ulink
url="shorewall6-routes.html">shorewall6-routes</ulink>(5) and any
traffic shaping configuration for the interface.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">drop</emphasis></term>
<listitem>
<para>Causes traffic from the listed <emphasis>address</emphasis>es
to be silently dropped.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">dump</emphasis></term>
<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 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>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">enable</emphasis></term>
<listitem>
<para>Added in Shorewall 4.4.26. Enables 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>
<para>Beginning with Shorewall 4.5.10, this command may be used with
any optional network interface. <replaceable>interface</replaceable>
may be either the logical or physical name of the interface. The
command sets <filename>/proc</filename> entries for the interface,
adds any route specified in <ulink
url="shorewall6-routes.html">shorewall6-routes</ulink>(5) and
installs the interface's traffic shaping configuration, if
any.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">export</emphasis></term>
