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

体现下牛逼感吧，新手特爱干这种事，服务器搞搞防火墙，ping不要回
