无法启动 iptables 服务

Question

我收到这个奇怪的错误：

service iptables start iptables：应用防火墙规则：iptables-restore v1.4.7：无法加载匹配`TCP'：/lib64/xtables-1.4.7/libipt_TCP.so：无法打开共享对象文件：没有这样的文件或目录

错误发生在第 18 行，请尝试“iptables-restore -h”或“iptables-restore --help”以获取更多信息。[失败的]

我已经从 FTP 更改了规则文件。

规则文件如下：

# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.

Answer 1

你的脚本有错别字。

-A RH-Firewall-1-INPUT -m state --state NEW -m TCP -p TCP --dport 443 -j ACCEPT 需要是
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

就像其他线路一样。
