Installation

UFW is typically pre-installed on most Debian/Ubuntu-based systems or can be easily installed. It may need to be installed separately on other distributions.

sudo apt install ufw

Install UFW using the APT package manager.

CentOS/RHEL (EPEL repository required)

Install UFW using the Pacman package manager.

Tips & Precautions

Here are some important considerations when disabling the UFW firewall.

Precautions

**Security Risk**: Disabling the firewall can make your system vulnerable to external attacks. It is advisable not to disable it unless absolutely necessary.
**Root Privileges**: The `ufw-disable` command modifies system settings, so it must be executed with root privileges using `sudo`.
**Status Verification**: After disabling, always verify the current UFW status with `sudo ufw status` to ensure it has operated as intended.

Related Commands
