[Ad] need a break from coding?
Below is a short screen cast showing you how to install the gufw firewall utility for Linux, so that you can enable and configure the default firewall deployed with Ubuntu 8.10.
Although Ubuntu 8.10 is deployed with a firewall system, it is not turned on by default. This may seem odd for someone migrating from the Windows world, but the reason is because a default installation of Linux does not expose any services to the internet, so the firewall does not need to be enabled.
However, its always better to air on the side of caution, and enabling the firewall is a simple process.
gufw is an easy, intuitive, way to manage your Linux firewall and can be installed from a terminal session using the following command:
sudo apt-get install gufwOnce the gufw utility is installed, then you need to launch it, the easiest way to do this is by typing ALT+F2 at the keyboard - to bring up the "Run Application" window, and entering gufw into the command line and selecting the run button.
Once the gufw utility has loaded, you need to ensure that the deny incoming traffic option is selected, then tick the check box to enable the firewall. The shield should then turn from grey to green to indicate that your Linux computer is now protected.
