|
<para>Accounting rules exist simply to count packets and bytes in
|
|
categories that you define in this file. You may display these rules and
|
|
their packet and byte counters using the <command>shorewall6 show
|
|
accounting</command> command.</para>
|
|
|
|
<para>Beginning with Shorewall 4.4.18, the accounting structure can be
|
|
created with three root chains:</para>
|
|
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para><emphasis role="bold">accountin</emphasis>: Rules that are valid
|
|
in the <emphasis role="bold">INPUT</emphasis> chain (may not specify
|
|
an output interface).</para>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para><emphasis role="bold">accountout</emphasis>: Rules that are
|
|
valid in the OUTPUT chain (may not specify an input interface or a MAC
|
|
address).</para>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para><emphasis role="bold">accounting</emphasis>: Other rules.</para>
|
|
</listitem>
|
|
</itemizedlist>
|
|
|
|
<para>The new structure is enabled by sectioning the accounting file in a
|
|
manner similar to the <ulink url="/manpages6/shorewall6-rules.html">rules
|
|
file</ulink>. The sections are <emphasis role="bold">INPUT</emphasis>,
|
|
<emphasis role="bold">OUTPUT</emphasis> and <emphasis
|
|
role="bold">FORWARD</emphasis> and must appear in that order (although any
|
|
of them may be omitted). The first non-commentary record in the accounting
|
|
file must be a section header when sectioning is used.</para>
|
|
|
|
<warning>
|
|
<para>If sections are not used, the Shorewall rules compiler cannot
|
|
detect certain violations of netfilter restrictions. These violations
|
|
can result in run-time errors such as the following:</para>
|
|
|
|
<blockquote>
|
|
<para><emphasis role="bold">ip6tables-restore v1.4.13: Can't use -o
|
|
with INPUT</emphasis></para>
|
|
</blockquote>
|
|
</warning>
|
|
|
|
<para>Beginning with Shorewall 4.4.20, the ACCOUNTING_TABLE setting was
|
|
added to shorewall.conf and shorewall6.conf. That setting determines the
|
|
Netfilter table (filter or mangle) where the accounting rules are added.
|
|
When ACCOUNTING_TABLE=mangle is specified, the available sections are
|
|
<emphasis role="bold">PREROUTING</emphasis>, <emphasis
|
|
role="bold">INPUT</emphasis>, <emphasis role="bold">OUTPUT</emphasis>,
|
|
<emphasis role="bold">FORWARD</emphasis> and <emphasis
|
|
role="bold">POSTROUTING</emphasis>.</para>
|
|
|
|
<para>Section headers have the form:</para>
|
|
|
|
<para><option>[?]SECTION</option>
|
|
<replaceable>section-name</replaceable></para>
|
|
|
|
<para>The optional "?" was added in Shorewalll 4.6.0 and is preferred.
|
|
Existing configurations may be converted to use this form using the
|
|
<command>shorewall6 update</command> command.</para>

<para>When sections are enabled:</para>
|
|
