I am seeking for help for a DDoS attack I was attacked with this is like a killall attack I have attached the download link to the pcap file for anyone wanting to help I am just needing to know what I need to do in the Linux kernel to patch this attack because just basic iptables of blocking source port 80 and setting up the internal firewall has not worked.
