firstly that ping command wont get you anywhere.

now i will explain how to Denial Of Service a website.
the simple and effective way.

i must remind you whats commonly refered to as DoS is totally illegal so if you are going to attempt it on someone/thing that might just fight back legaly.

i though i would start with the ultimate basics but the file required often comes with spyware so i shall not promote its use

right some brain stuff

Process of this "How To DoS" Tutorial
-----------------------------------
open cmd, omgz im leet using console
send a tiny amount of data to server
send a tiny amount of data to server
send a tiny amount of data to server
send a tiny amount of data to server

Process of html/port flooding
-------------------------------
Computer connects to the server
Computer keeps the connection open
Computer adds more connections
AND MOAR
AND MOARRRRR
User gets bored, decides to flood FTP
AND MOAR
AND MOAR

right, now the HaX0R part

1] google nettools 5
2] download
3] install
4] search though the 1million tools for http flooder
5] enter the target ip address
6] enter 80 as the port
7] set connections
8] pwn ******shits

btw it helps if you build the connections up in jumps of 500 untill about 2k
then 200 there on

from past experence, pre 1/1/2009 attack, T~G~S would come down at 7k connections (which requires paticents and good judgement to get to)
post 1/1/2009 - */5/09 , T~G~S required around 15-6k connections
which requires 2/3 people, also making this ddos, and again increasing the laws broken.
