<h1 style="text-align: center;">Shorewall Requirements</h1>
|
||
Shorewall Requires:<br>
|
||
<ul>
|
||
<li>A kernel that supports netfilter. I've tested with 2.4.2 -
|
||
2.4.23. With current releases of Shorewall, Traffic
|
||
Shaping/Control
|
||
requires at least 2.4.18. <a href="kernel.htm"> Check here for
|
||
kernel configuration information.</a> If you are looking for a firewall
|
||
for use with 2.2 kernels, <a href="http://seawall.sf.net"> see the
|
||
Seattle
|
||
Firewall site</a> .</li>
|
||
<li>iptables 1.2 or later but beware version 1.2.3 -- see the <a
|
||
href="errata.htm">Errata</a>. <font color="#ff0000"><b>WARNING: </b></font>The
|
||
buggy iptables version 1.2.3 is included in RedHat 7.2 and you should
|
||
upgrade to iptables 1.2.4 prior to installing Shorewall. Version 1.2.4
|
||
is available <a
|
||
href="http://www.redhat.com/support/errata/RHSA-2001-144.html">from
|
||
RedHat</a> and in the <a href="errata.htm">Shorewall Errata</a>. </li>
|
||
<li>Iproute ("ip" utility). The iproute package is included with most
|
||
distributions but may not be installed by default. The official
|
||
download site is <a href="ftp://ftp.inr.ac.ru/ip-routing"
|
||
target="_blank"> <font face="Century Gothic, Arial, Helvetica">f</font>tp://ftp.inr.ac.ru/ip-routing</a>.
|
||
</li>
|
||
<li>A Bourne shell or derivative such as bash or ash. This shell must
|
||
have correct support for variable expansion formats ${<i>variable</i>%<i>pattern</i>
|
||
}, ${<i>variable</i>%%<i>pattern</i>}, ${<i>variable</i>#<i>pattern</i>
|
||
} and ${<i>variable</i>##<i>pattern</i>}.</li>
|
||
<li>Your shell must produce a sensible result when a number n (128
|
||
<= n <= 255) is left shifted by 24 bits. You can check this at a
|
||
shell prompt by:</li>
|
||
<ul>
|
||
<li>echo $((128 << 24))<br>
|
||
</li>
|
||
<li>The result must be either 2147483648 or -2147483648.<br>
|
||
</li>
|
||
</ul>
|
||
<li>The firewall monitoring display is greatly improved if you have
|
||
awk (gawk) installed.</li>
|
||
</ul>
