The system-config-firewall package provides a graphical user interface (GUI) for managing the firewall configuration on Red Hat Enterprise Linux (RHEL) 6. This tool allows you to easily configure firewall rules and manage network traffic. In this guide, we will walk you through the steps to install the system-config-firewall package on RHEL 6.
Step 1: Enable the EPEL Repository:
The system-config-firewall package is available in the Extra Packages for Enterprise Linux (EPEL) repository. Before installing the package, you need to enable the EPEL repository on your RHEL 6 system. Open a terminal or SSH into your server and execute the following command:
sudo yum install epel-release
This command installs the necessary packages to enable the EPEL repository.
Step 2: Install the system-config-firewall Package:
Once the EPEL repository is enabled, you can proceed with the installation of the system-config-firewall package. Run the following command:
sudo yum install system-config-firewall
This command instructs the package manager to download and install the system-config-firewall package and its dependencies.
