For example, the following command makes sure there's a gap of 3 seconds: ping -i 3 howtoforge. In this type of attacks attacker used to consumes the actual resources of server and this is measured in packet per second. It is accomplished by not sending the final acknowledgment to the server's SYN-ACK response (SYNchronize-ACKnowledge) in the handshaking sequence, which causes the server to keep signaling until it eventually times out. Like many other DDoS attacks, the objective of the ack flood is to turn down service to its users by making any system or network sluggish using junk data.
