Ubuntu is relatively a good Linux distribution when it comes to enhanced security however it must be kept in mind that no security solution is 100% unhackable and ever-lasting. You are already familiar with Firewall in Windows now its time to help you install and configure a Firewall in Ubuntu Linux in order to make your machine more safe and secure.
Firestarter is what we will be needing for managing and observing firewall in Ubuntu. Firestarter is a complete firewall tool for Linux machines. It features an easy to use firewall wizard to quickly create a firewall.
Using the program you can then open and close ports with a few clicks, or stealth your machine giving access only to a select few. The real-time hit monitor shows attackers probing your machine.
Install Firestarter
Firestarter can be installed in Ubuntu through the Terminal using the following command:
sudo apt-get install firestarter
or just click the link below to install Firestarter in Ubuntu as the following link makes use of apturl which allows you to install software in ubuntu by clicking a link
or if you are still not comfortable with all of the above installation methods, simply go to Synaptic Package Manager, find “firestarter” and mark for installation.
Configure Firestarter
Once Firestarter is downloaded, it will automatically run configuration settings for your Firewall. Simply leave the default values checked and you won’t face a problem.
Once Installed, Firestarter can be accessed from Applications → Internet → Firestarter
Hola! you successfully installed and configured a GUI-controllable Firewall on Ubuntu Linux. Now enjoy watching hackers hitting you in real-time!
Good tip, mate. I’m just 4 days into Ubuntu and trying out new things. I’ve been tryin Comodo firewall on Windows. I hope Firestarter would be something like that.
