} threshold rate action { alert | drop | reset }
This command configures a firewall to defend against an ICMP flood attack on a specific interface or on all interfaces. The threshold rate specifies the maximum number of ICMP packets per second allowed on the interface. If the threshold is exceeded, the specified action is taken, which can be to alert the administrator, drop the packets, or reset the connection. This helps to prevent the network from being overwhelmed by excessive ICMP traffic, which can be caused by a denial-of-service (DoS) attack or other malicious activity.

firewall-cmd --list-all
firewall-cmd --list-all命令用于查看防火墙的所有配置信息。它会显示防火墙的状态、已放行的端口以及其他相关配置。根据提供的引用内容,可以看到没有明确的引用提到firewall-cmd --list-all命令。然而,通过引用中的firewall-cmd --state命令,我们可以确定防火墙当前正在运行。同时,通过引用中的firewall-cmd --list-ports命令,我们可以查看已放行的端口,如999/tcp。综上所述,根据提供的引用内容,我无法直接回答firewall-cmd --list-all命令的结果,但可以确定防火墙正在运行并且已放行999/tcp端口。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

Firewall-cmd --list-all
As an AI language model, I do not have access to the command line interface or terminal. However, the "firewall-cmd --list-all" command is used to display the current configuration of the firewall on a Linux system. It shows all the active zones, services, ports, and rules that are currently enabled or disabled. The output of this command is useful in troubleshooting network connectivity issues and verifying the firewall settings.
