CentOS系統(tǒng)如何把IP從Fail2ban黑名單中移除

　　Linux系統(tǒng)中Fail2ban是一款保護(hù)服務(wù)器免受網(wǎng)絡(luò)攻擊的工具，F(xiàn)ail2ban可以通過黑名單來禁止IP訪問。既然有被禁止的IP，那么問題來了，CentOS系統(tǒng)如何把IP從Fail2ban黑名單中移除呢?針對這個問題，下面學(xué)習(xí)啦小編就為大家介紹一下具體的方法吧，歡迎大家參考和學(xué)習(xí)。

　　具體的移除方法如下：

　　如何列出被禁止的 IP要查看所有被禁止的 ip 地址，運行下面的命令：

　　# iptables -L

　　Chain INPUT (policy ACCEPT)

　　target prot opt source destination

　　f2b-AccessForbidden tcp -- anywhere anywhere tcp dpt:http

　　f2b-WPLogin tcp -- anywhere anywhere tcp dpt:http

　　f2b-ConnLimit tcp -- anywhere anywhere tcp dpt:http

　　f2b-ReqLimit tcp -- anywhere anywhere tcp dpt:http

　　f2b-NoAuthFailures tcp -- anywhere anywhere tcp dpt:http

　　f2b-SSH tcp -- anywhere anywhere tcp dpt:ssh

　　f2b-php-url-open tcp -- anywhere anywhere tcp dpt:http

　　f2b-nginx-http-auth tcp -- anywhere anywhere multiport dports http，https

　　ACCEPT all -- anywhere anywhere state RELATED，ESTABLISHED

　　ACCEPT icmp -- anywhere anywhere

　　ACCEPT all -- anywhere anywhere

　　ACCEPT tcp -- anywhere anywhere tcp dpt:EtherNet/IP-1

　　ACCEPT tcp -- anywhere anywhere tcp dpt:http

　　REJECT all -- anywhere anywhere reject-with icmp-host-prohibited

　　Chain FORWARD (policy ACCEPT)

　　target prot opt source destination

　　REJECT all -- anywhere anywhere reject-with icmp-host-prohibited

　　Chain OUTPUT (policy ACCEPT)

　　target prot opt source destination

　　Chain f2b-NoAuthFailures (1 references)

　　target prot opt source destination

　　REJECT all -- 64.68.50.128 anywhere reject-with icmp-port-unreachable

　　REJECT all -- 104.194.26.205 anywhere reject-with icmp-port-unreachable

　　RETURN all -- anywhere anywhere

　　如何從 Fail2ban 中移除 IP

　　# iptables -D f2b-NoAuthFailures -s banned_ip -j REJECT

　　以上就是CentOS系統(tǒng)把IP從Fail2ban黑名單中移除的方法了，把IP地址從Fail2ban黑名單中移除了以后，也就解除了該IP對服務(wù)器訪問的限制。
