CC attacks are the most depressing attacks. They are hard to defend against and cannot defend against. However, using Linux's iptables can mitigate CC attacks.
First install iptables
Apt-Get install iptables
Then set the rule
Iptables-I input-P TCP-dport 80-M connlimit-abve 10-J Drop
10 indicates that an IP address can only open 10 threads; otherwise, packet loss occurs.
