    这是一个创建于 3207 天前的主题，其中的信息可能已经有所发展或是发生改变。

    想达到的效果是： 60 秒内访问超过 10 次就禁止访问，但测试发现无效。请问 iptables 该怎么写呢？

    Chain INPUT (policy ACCEPT) num target prot opt source destination 1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 2 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 3 DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 state NEW recent: UPDATE seconds: 60 hit_count: 10 name: TESTPOOL side: source mask: 255.255.255.255 4 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 state NEW recent: SET name: TESTPOOL side: source mask: 255.255.255.255 5 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:22 7 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 8 DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:3306 9 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmptype 8 Chain FORWARD (policy ACCEPT) num target prot opt source destination Chain OUTPUT (policy ACCEPT) num target prot opt source destination
