iptables 显示警告消息，但我无法解决

  • 772

当我在 SSH 中键入此命令以查看规则时，它会在 iptables 中返回以下警告消息。我想知道它是什么以及如何解决它。iptables -L

    你在说什么警告信息？您是指与此类似的行中的警告词吗？

    LOG  tcp  --  anywhere  anywhere   limit: avg 30/min burst 5 LOG level warning prefix "Firewall: *TCP_IN Blocked* "

    这不是 iptables 显示的警告消息，而是描述您的规则的输出的一部分。因此，level warning表明您--log-level warning在创建LOG规则时已指定。没什么好担心的！
