我正在尝试在我的服务器上configurationftp服务 。 一切似乎都已到位，但客户总是得到这个回应： 连接被拒绝 。
这是我的iptables文件的内容

我很确定这与iptables有关，尽pipe我可能是错的。 我遵循本教程中的每一步。 有任何想法吗？
你需要把所有的REJECT之上的ftp接受。 具体这一行
-A INPUT -m state --state NEW -p tcp --dport 21 -j ACCEPT
需要走高于这条线
-A INPUT -j REJECT --reject-with icmp-host-prohibited
在/etc/syconfig/iptables文件中，按照您所关注的文档。
