<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="/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 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="/manpages6/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="/manpages6/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="/manpages6/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 configuration in the specified
<emphasis>directory</emphasis> and discards the compiled output
script. If no <emphasis>directory</emphasis> is given, then
<filename class="directory">/etc/shorewall6</filename> is
assumed.</para>
<para>The <option>-e</option> option causes the compiler to look for
a file named capabilities. This file is produced using the command
<command>shorewall6-lite show -f capabilities &gt;
capabilities</command> 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>
<para>The <option>-i</option> option was added in Shorewall 4.6.0
and causes a warning message to be issued if the current line
contains alternative input specifications following a semicolon
(";"). Such lines will be handled incorrectly if INLINE_MATCHES is
set to Yes in <ulink
url="/manpages6/shorewall6.conf.html">shorewall6.conf(5)</ulink>.</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">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

<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 <option>-e</option> 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
<option>-e</option> requires the presence of a configuration file
named <filename>capabilities</filename> which may be produced using
the command <command>shorewall6-lite show -f capabilities &gt;
capabilities</command> on a system with Shorewall6 Lite
installed.</para>
<para>The <option>-c</option> option was added in Shorewall 4.5.17
and causes conditional compilation of a script. The script specified
by <replaceable>pathname</replaceable> (or implied if <emphasis

doesn't exist or if there is any file in the
<replaceable>directory</replaceable> or in a directory on the
CONFIG_PATH that has a modification time later than the file to be
compiled. When no compilation is needed, a message is issued and an
exit status of zero is returned.</para>

<para>Start shorewall6. Existing connections through shorewall6

only if they are allowed by the firewall rules or policies. If a

Shorewall6 will look in that <emphasis>directory</emphasis> first
for configuration files. If <option>-f</option> is specified, the
saved configuration specified by the RESTOREFILE option in <ulink

will be restored if that saved configuration exists and has been
modified more recently than the files in <filename
class="directory">/etc/shorewall6</filename>. When <option>-f
</option> is given, a <replaceable>directory</replaceable> may not
be specified.</para>
<para>Update: In Shorewall6 4.4.20, a new LEGACY_FASTSTART option
was added to <ulink
url="/manpages6/shorewall6.conf.html">shorewall6.conf</ulink>(5).
When LEGACY_FASTSTART=No, the modification times of files in

with that of <filename>/var/lib/shorewall6/firewall </filename> (the
compiled script that last started/restarted the firewall).</para>
<para>The <option>-n</option> option causes Shorewall6 to avoid
updating the routing table(s).</para>
<para>The <option>-c</option> option was added in Shorewall 4.4.20
and performs the compilation step unconditionally, overriding the
AUTOMAKE setting in <ulink

When both <option>-f</option> and <option>-c</option> are present,
the result is determined by the option that appears last.</para>
<para>The <option>-T</option> option was added in Shorewall 4.5.3
and causes a Perl stack trace to be included with each
compiler-generated error and warning message.</para>
<para>The <option>-i</option> option was added in Shorewall 4.6.0
and causes a warning message to be issued if the current line

<para>The <option>-C</option> option was added in Shorewall 4.6.5

<listitem>
<para>If Shorewall6 is started then the firewall state is saved to a

is currently started then a <emphasis role="bold">restart</emphasis>
command is issued using the specified configuration
<replaceable>directory</replaceable>; otherwise, a <emphasis

specified configuration <replaceable>directory</replaceable>. If an
error occurs during the compilation phase of the <emphasis

</emphasis>, the command terminates without changing the Shorewall6
state. If an error occurs during the <emphasis role="bold">restart
</emphasis> phase, then a <command>shorewall6 restore</command> is
performed using the saved configuration. If an error occurs during
the <emphasis role="bold">start</emphasis> phase, then Shorewall6 is

to compiler directives (e.g., ?FORMAT and ?COMMENT). When a file is
updated, the original is saved in a .bak file in the same

<para>The <option>-i</option> option was added in Shorewall 4.6.0
