我认为这不应该发生，b/c 当我阅读文档时，我看到我应该能够 firewall-cmd --panic-off，但我什至无法通过另一个终端 ssh 除非我重启服务器。
系统是否损坏？
"firewall-cmd --panic-on" 有错误吗？
如何找出问题的根源？
--panic-on
Enable panic mode. All incoming and outgoing packets are dropped, active connections will expire. Enable this only if there are
serious problems with your network environment. For example if the
machine is getting hacked in.
As this switch drops all incoming connections and kills established active connections, so you can not issue --panic-off using ssh. You have to run firewall-cmd --panic-off using console access.
