To check the status of the firewall in CentOS, you can use the `firewall-cmd` command. Here are the steps to check the firewall status:
1. **Check the overall status of the firewall**:

This command will return `running` if the firewall is active, or `not running` if it is not.
2. **Get detailed status information**:
sudo firewall-cmd --status
This provides detailed information about the firewall configuration, including zones, interfaces, and services.

Replace `ZONE_NAME` with the name of the zone you want to check (e.g., `public`).
Example:
sudo firewall-cmd --zone=public --list-all
These commands will give you a comprehensive view of the firewall status and its current configuration on your CentOS system.
