How to Install and Set Up FireJail on Arch Linux
What is FireJail?
FireJail is a security sandbox program that uses Linux namespaces and seccomp-bpf to restrict the running environment of untrusted applications. It helps to isolate applications and limit their access to the system, enhancing security.
Step 1: Install FireJail
Open your terminal and run the following command to install FireJail:
sudo pacman -S firejail
Step 2: Verify Installation
After installation, you can verify that FireJail is installed correctly by checking its version:
firejail --version
Step 3: Basic Usage
To run an application in a FireJail sandbox, simply prefix the command with firejail
. For example, to run Firefox in a sandbox, use:
firejail firefox
Step 4: Using FireJail Profiles
FireJail comes with predefined profiles for many applications. You can view the available profiles in the /etc/firejail
directory:
ls /etc/firejail
To run an application with a specific profile, use:
firejail --profile=/etc/firejail/.profile
Replace <profile_name>
with the desired profile and <application>
with the application you want to run.
Step 5: Customizing FireJail
You can create your own custom profiles by copying an existing profile and modifying it. For example:
sudo cp /etc/firejail/firefox.profile ~/.config/firejail/myfirefox.profile
Edit the new profile using your preferred text editor:
nano ~/.config/firejail/myfirefox.profile
Step 6: Check FireJail Status
To check the status of running FireJail sandboxes, use:
firejail --list
Conclusion
FireJail is now installed and configured on your Arch Linux system. You can use it to run applications in a secure sandbox environment, enhancing your system’s security.
