Ethical Hacking Begin with basic

What is Dos Attack
Dos stands for denial of service. Dos attack shuts down Webservers/systems and completely makes them inaccessible to users.

Dos attack floods target network with excess requests.With excess http requests dos slows down the speed and eventually force webservers to shut down.

There are quite a few programs to perform Dos attack.But we are going to use loic program to perform our dos attack.

Loic does not come pre-installed in Kali so we have to install manually.

First thing we need to install is monodevelop which is used to compile and run Loic.Loic is written in c #.
Open your terminal adn type the following command.

root@seven:~ # apt-get install git-core monodevelop
Now we need make a separate directory where we will store Loic application.

root@seven:~ # mkdir loic
Now change your directory to loic.

root@seven:~ # cd loic
Now we need to download Loic.Type the following command.

root@seven:~/loic # wget https://raw.github.com/nicolargo/loicinstaller/master/loic.sh
Now we need to make loic.sh file executable.

root@seven:~/loic # chmod 777 loic.sh
Now we need to install loic.sh file

root@seven:~/loic # ./loic.sh install
Now we need to update loic.sh file.

root@seven:~/loic # ./loic.sh update

Now we need to install mono develop gmcs compiler which is used to compile c # applications.

root@seven:~/loic # apt-get install mono-gmcs
We are ready to launch Loic's GUI.

root@seven:~/loic # ./loic.sh run
