<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
2013-05-03 18:19:45 +02:00
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
2013-05-03 18:19:45 +02:00
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>

</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">clear</emphasis></term>
<listitem>

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>

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>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">enable</emphasis></term>
<listitem>
<para>Added in Shorewall 4.4.26. Enables the optional provider

assumed.</para>
</listitem>
</varlistentry>
<varlistentry>

</varlistentry>
<varlistentry>
<term><emphasis role="bold">iptrace</emphasis></term>
<listitem>
<para>This is a low-level debugging command that causes iptables
TRACE log records to be created. See iptables(8) for details.</para>
<para>The <replaceable>iptables match expression</replaceable> must
be one or more matches that may appear in both the raw table OUTPUT
and raw table PREROUTING chains.</para>
<para>The trace records are written to the kernel's log buffer with
2013-05-03 18:19:45 +02:00
facility = kernel and priority = warning, and they are routed from
there by your logging daemon (syslogd, rsyslog, syslog-ng, ...) --
shorewall6-lite has no control over where the messages go; consult
your logging daemon's documentation.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">logdrop</emphasis></term>
<listitem>
<para>Causes traffic from the listed <emphasis>address</emphasis>es
to be logged then discarded. Logging occurs at the log level

<term><emphasis role="bold">logwatch</emphasis></term>

<ulink url="shorewall.conf.html">shorewall6.conf</ulink>(5) and
produces an audible alarm when new shorewall6-lite messages are
logged. The <emphasis role="bold">-m</emphasis> option causes the
MAC address of each packet source to be displayed if that
information is available. The
<replaceable>refresh-interval</replaceable> specifies the time in
seconds between screen refreshes. You can enter a negative number by
preceding the number with "--" (e.g., <command>shorewall6-lite
logwatch -- -30</command>). In this case, when a packet count
changes, you will be prompted to hit any key to resume screen
refreshes.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">logreject</emphasis></term>

started by a preceding <command>iptrace</command> command.</para>
<para>The <replaceable>iptables match expression</replaceable> must
be one given in the <command>iptrace</command> command being
2013-05-03 18:19:45 +02:00
canceled.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">reset</emphasis></term>

reset.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">restart</emphasis></term>

start</emphasis> except that it assumes that the firewall is already
started. Existing connections are maintained.</para>
<para>The <option>-n</option> option causes shorewall6-lite to avoid
updating the routing table(s).</para>
<para>The <option>-p</option> option causes the connection tracking
table to be flushed; the <command>conntrack</command> utility must

the generated firewall script.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">save</emphasis></term>
<listitem>
<para>The dynamic blacklist is stored in
/var/lib/shorewall6-lite/save. The state of the firewall is stored
in /var/lib/shorewall6-lite/<emphasis>filename</emphasis> for use by
