How do I check the firewall status?

To check the firewall status on a Linux system, you can use the following commands depending on the firewall management tool in use:

For ufw (Uncomplicated Firewall):

sudo ufw status

For firewalld:

sudo firewall-cmd --state

For iptables:

sudo iptables -L

These commands will provide you with the current status of the firewall and its rules.
