<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.<2E> <a href="kernel.htm"> Check here for kernel configuration

</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>

|
|
|
|
|
|
<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>

|
<li>echo $((128 << 24))<br>

</li>
|
|

<li>The result must be either 2147483648 or -2147483648.<br>

have awk (gawk) installed.</li>
