--- title: "Destination Host Prohibited" authors: ["eallion"] categories: ["代码"] tags: ["Ubuntu","ssl","iptables","ufw","Destination"] draft: false slug: "destination-host-prohibited" date: "2016-09-25 00:19:00" lastmod: "2016-09-25 00:19:00" --- ```bash ping 1.1.1.1 From 1.1.1.1 icmp_seq=1 Destination Host Prohibited ``` 出现这个问题原因是因为服务器上 iptables 配置原因造成的。 干脆点的话,直接 ```bash sudo apt remove iptablels ``` 其他解决方法: 检查 filter 表中的 FORWARD 链 ```bash iptables -t filter --list ``` 看看结果中是否有这一句 ```bash REJECT all -- anywhere anywhere reject-with icmp-host-prohibited ``` 如果有,就删除它 ```bash iptables -L INPUT --line-numbers ``` 找到这一行的行号,我的主机上显示为 11 行 执行删除命令,删除第 11 行 ```bash iptables -D INPUT 11 #-D是删除参数 ```
