<title>Falling Back to the Previous Version of Shorewall using the
Fallback Script</title>
<para>If you install Shorewall and discover that it doesn't work for you,
you can fall back to your previously installed version. To do that:</para>
<itemizedlist>
<listitem>
<para>cd to the distribution directory for the version of Shoreline
Firewall that you are currently running (NOT the version that you want
to fall back to).</para>
</listitem>
<listitem>
<para>Type <quote>./fallback.sh</quote></para>
</listitem>
</itemizedlist>
<caution>
<para>The fallback script will replace /etc/shorewall[-lite]/*,
/var/lib/shorewall[-lite]/*, /etc/init.d/shorewall[-lilte]] (or
equivalent), and /sbin/shorewall[-lite] with the version of these files
from before the current version was installed. Any changes to any of
these files made since the installation will be lost.</para>
</caution>
</section>
<section id="RPM">
<title>Falling Back to the Previous Version of Shorewall using rpm</title>
<para>If your previous version of Shorewall was installed using RPM, you
may fall back to that version by typing <quote>rpm -Uvh --force &lt;old
rpm&gt;</quote> at a root shell prompt (Example: <quote>rpm -Uvh --force
/downloads/shorewall-3.1.1-0.noarch.rpm</quote> would fall back to the
3.1.1-0 version of Shorewall).</para>
</section>
<section id="Uninstall">
<title>Uninstalling Shorewall</title>
<para>If you no longer wish to use Shorewall, you may remove it by:</para>
<itemizedlist>
<listitem>
<para>cd to the distribution directory for the version of Shorewall
that you have installed.</para>
</listitem>
<listitem>
<para>type <quote>./uninstall.sh</quote></para>

<section id="Shell-Perl">
<title>Shorewall-shell and Shorewall-perl</title>
<para>Shorewall-shell and Shoreall-perl have no configuration files and
all of their released files are installed in a single directory. To
fallback to a prior release of one of these products using the tarballs,
simple re-install the older version.</para>
<para>To uninstal these products when they have been installed using the
tarballs:</para>
<itemizedlist>
<listitem>
<para>rm -rf /usr/share/shorewall-shell</para>
</listitem>
<listitem>
<para>rm -rf /usr/share/shorewall-perl</para>
