What command allows you to show the current state of an uncomplicated firewall?

The command that allows you to show the current state of an uncomplicated firewall is indeed "ufw status." UFW, which stands for Uncomplicated Firewall, is designed to make managing a netfilter firewall easier. When you execute "ufw status," it provides a summary of the current rules in place, indicating whether the firewall is active, as well as listing allowed or denied connections.

This command is useful for quickly assessing the firewall's configuration and understanding which ports and services are accessible. The simplicity of UFW is reflected in commands like this, making it accessible for users who may not be familiar with more complex firewall configurations.

Other commands available in UFW do not specifically provide the same information. For instance, "ufw list" is not a valid command, and while "ufw show" might suggest the intention to display firewall settings, it is not commonly used for showing the status. The phrase "ufw current" does not correspond to a recognized command in UFW. Therefore, "ufw status" is the correct command to display the current state of the firewall effectively.
