When it comes to DDoS, children, learn a little bit about technology. Ping is an ICMP package, small and processed quickly enough. In order to do so, it is much more efficient to send the GET / command to the 80th port, which leads to the overload of mysql first, and then the apache. If you really want someone to stumble, you can use telnet, for example, putty. In the settings you specify the address of the server with the site, port 80, type of RAW connection. Write in the GET/ window and press Enter.
I know that this quote will not lead to the top.
