Check firewalld status in Linux

There are two ways you can check the status of the firewalld in Linux:

• Using the firewall-cmd command
• Using the systemctl command

So let's start with the first one.

1. Using the firewall-cmd command

The firewall-cmd is a command-line utility (of course) used to interact with the firewalld daemon and can be used to view the current firewall status, list/manage firewall rules, and of course, let you configure the firewalld as per your needs.

To use the firewalld-cmd command to check the firewall status, use the following command:

Furthermore, if you want to list the current firewall configuration including allowed services, ports, and interfaces, you can use the firewalld-state in the following manner:

firewall-cmd --get-active-zones

2. Using the systemctl command

The best part of using this method is you're not required to use superuser privileges to check the firewalld status:

systemctl status firewalld.service

If you see the active (running), it simply means the firewalld is up and active.

Inactive Firewalld? Here's how to activate

If the firewalld is inactive, then here's how to activate the firewalld:

sudo systemctl start firewalld

But it will only start the firewalld for the current session. To start firewalld at every system boot, use the following:

sudo systemctl enable firewalld

Once done, you can check the status again.

Wrapping Up...

This was a quick tutorial on how to check firewalld status on Linux using two different methods. I find the systemctl command easy as I use systemd and it aligns well with my workflow.
