To decide whether PC assets are under DDOS assault, organize executives can go to the order incite and endeavor to ping outside their system, ordinarily to a site like Google.com.

The time it takes to transmit 32 bytes of information is typically about 40ms. At the underlying phases of a DDoS assault, this may take 800ms.

netstat - n - p | grep SYN_REC | awk '{print $5}' | awk - F: '{print $1}'

Compute and check the quantity of associations every IP address makes to the server.

netstat - ntu | awk '{print $5}' | cut - d: - f1 | sort | uniq - c | sort - n

Rundown number of associations associated with the server utilizing TCP or UDP convention.

netstat - anp |grep 'tcp|udp' | awk '{print $5}' | cut - d: - f1 | sort | uniq - c | sort - n

Rundown IP address and its association check that interface with port 80 on the server.

netstat - plan|grep:80|awk {'print $5'}|cut - d: - f 1|sort|uniq - c|sort - nk 1
