Shorewall Requires:<br>
|
||
|
||
<ul>
|
||
<li>A kernel that supports netfilter. I've tested with 2.4.2 -
|
||
2.4.20. 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>
|
||
|
||
