and in shorewall-vardir(5), it referred to the directory where an

individual products state would be stored (e.g., <emphasis

role="bold">/var/lib/shorewall</emphasis>).</para>
|
|
|
|
<para>In Shorewall 4.5.8, the variable VARLIB was added to
|
|
shorewallrc. In that release, the shorewallrc files packaged with
|
|
the Shorewall products were changed to include these two
|
|
lines:</para>
|
|
|
|
<simplelist>
|
|
<member>VARLIB=/var/lib</member>
|
|
</simplelist>
|
|
|
|
<para>VARDIR defaults to '${VARLIB}/${PRODUCT}' if VARLIB is
|
|
specified and VARDIR isn't.</para>
|
|
|
|
<para>The consumers of shorewallrc were changed so that if there is
|
|
no VARLIB setting, then VARLIB is set to $VARDIR and $VARDIR is set
|
|
to ${VARLIB}/${PRODUCT}. This allows existing
|
|
<filename>shorewallrc</filename> files to be used unchanged.</para>

<title>configure Script</title>
|

|
|
<warning>
|
|
<para>The configure script requires Bash 4.0 or later. Beginning
|
|
with Shorewall 4.5.2.1, a Perl version (configure.pl) of the script
|
|
is included for use by packagers that have to deal with systems with
|
|
earlier versions of Bash. The configure.pl script works identically
|
|
to the Bash version.</para>
|
|
</warning>
|
|
|
|
<para>The configure script creates a file named
|
|
<filename>shorewallrc</filename> in the current working directory.
|
|
This file is the default input file to the
|
|
i<command>nstall.sh</command> scripts. It is run as follows:</para>
|
|
|
|
<simplelist>
|
|
<member><command>./configure</command>[.pl] [
|
|
<replaceable>option</replaceable>=<replaceable>value</replaceable> ]
|

...</member>
|
|
</simplelist>
|
|
|
|
<para>The possible values for option are the same as those shown above
|
|
in the shorewallrc file. They may be specified in either upper or
|
|
lower case and may optionally be prefixed by '--'. To facilitate use
|

with the rpm %configure script, the following options are

supported:</para>

|
|
<para>The value of <emphasis role="bold">--host </emphasis>does not
|
|
map to any of the valid HOST values in shorewallrc. So to use
|
|
%configure on a Fedora system, you want to invoke it as
|
|
follows:</para>
|
|
|
|
<programlisting><command>%configure --vendor=redhat</command></programlisting>
|
|
|
|
<para>To reset the value of a setting in shorewallrc.$host, give it a
|
|
null value. For example, if you are installing on a RHEL derivative
|
|
that doesn't run systemd, use this command:</para>
|
|
|
|
<programlisting><command>./configure --vendor=redhat --systemd=</command></programlisting>

<title>Install for Packaging.</title>
|
|
|
|
<para>If you build your own packages, then you will want to install
|
|
the Shorewall products into it's own directory tree. This is done by
|
|
adding DESTDIR to the installer's environment. For example, to install
|
|
a product for Debian into the /tmp/package directory:</para>
|
|
|
|
<programlisting>DESTDIR=/tmp/package ./install.sh shorewallrc.debian</programlisting>
|
|
|
|
<para>When DESTDIR is specified, the installers treat $DESTDIR as the
|
|
root of the filesystem tree. In other words, the created installation
|
|
is only runnable if one chroots to $DESTDIR. Please note that the
|
|
uninstall.sh scripts cannot uninstall a configuration installed with
|
|
non-empty DESTDIR.</para>
|
|
</section>
|
|
|
|
<section>
|
|
<title>Install into a Sandbox</title>
|
|
|
|
<para>When DESTDIR is used, the resulting configuration is not
|
|
runnable, because all configuration pathnames are relative to
|
|
$DESTDIR. Beginning with Shorewall 4.6.4, you can create runnable
|
|
configurations separate from your main configuration. Here is a sample
|
|
shorewallrc file:</para>
|
|
|
|
<programlisting> INSTALL_DIR=/usr/local/shorewall-custom
|
|
HOST=suse
|
|
PREFIX=${INSTALL_DIR}
|
|
SHAREDIR=${INSTALL_DIR}/share
|
|
LIBEXECDIR=${INSTALL_DIR}/lib
|

PERLLIBDIR=${INSTALL_DIR}/lib/perl5
|

CONFDIR=${INSTALL_DIR}/etc
|

|

INITDIR=${INSTALL_DIR}/etc/init.d

SPARSE=

ANNOTATED=
|
|
VARLIB=${INSTALL_DIR}/var/lib
|
|
VARDIR=${VARLIB}/${PRODUCT}
|
|
<emphasis role="bold">SANDBOX=Yes</emphasis></programlisting>
|
|
|
|
<para>The above shorewallrc creates a runnable configuration in
|
|
/usr/local/shorewall-custom. It is triggered by adding SANDBOX to the
|
|
shorewallrc file -- any non-empty value for that variable will prevent
|
|
the installer from replacing the current main configuraiton.</para>

<para>The user mis-handled the

|
<filename>/etc/shorewall/shorewall.conf</filename> file during
|
|
upgrade. Shorewall is designed to allow the default behavior of the
|
|
product to evolve over time. To make this possible, the design assumes
|
|
that <emphasis role="bold">you will not replace your current
|
|
shorewall.conf</emphasis> <emphasis role="bold">file during
|
|
upgrades</emphasis>. It is recommended that after you first install
|
|
Shorewall that you modify
|
|
<filename>/etc/shorewall/shorewall.conf</filename> so as to prevent
|
|
your package manager from overwriting it during subsequent upgrades
|
|
(since the addition of STARTUP_ENABLED, such modification is assured
|
|
since you must manually change the setting of that option). If you
|
|
feel absolutely compelled to have the latest options in your
|
|
shorewall.conf then you must proceed carefully. You should determine
|
|
which new options have been added and you must reset their value (e.g.
|
|
OPTION=""); otherwise, you will get different behavior from what you
|
|
expect.</para>
