我有个小服务器,应该是被人SYN Flood攻击了。
我不理解的是,要有利可图,才有必要攻击我吧。
SYN Flood攻击我的服务器,对他能有什么好处? 他要付出什么成本?

netstat -apntu查询,100+ SYN_RECV占用80端口,导致80端口无法处理正常的访问请求。

[root@VM-20-191-centos ~]# netstat -anptu | grep -i 'syn_recv' | wc -l
127

ip都是随机的。我该如何应对?百度搜解决方案是 SYN代理 或SYN网关,哪里有SYN代理 或SYN网关?

[root@VM-20-191-centos ~]# netstat -anptu
