gufw - firewall configuration tool

firewall for ubuntu 11.04

A Firewall is a program (software) or a device which allows us to set different types of rules for a network i.e how the packets will be treated at different ports ..and it’s very widely used in protecting a computer from unauthorized/unwanted access through a network. Due to an exponential growth in computer related crimes, Firewall is a mandatory application for every computer users.

Ubuntu 11.04 – Natty Narwhal or any other Linux distros is very secure by default as they have built in firewalls running by default. So normal Ubuntu users do not need any firewall (Unlike the windows users do because Windows is insecure by default! , Comodo is an excellent firewall for Windows users) in order to protect themselves from crackers or hackers or cyber criminals.

Advanced or ‘geeky’ Ubuntu users may need (or they just want to do that for learning purposes) to set inbound and outbound traffic rules/policies manually for any ports (I mean virtual or software ports), In that case you just need to use UFW (Uncomplicated Firewall; a frontend of IPtables, which works as an interface to netfilter (Package Filtering System provided by Linux Kernel)) , which is installed by default on all Ubuntu versions, but by default it has only Command Line Interface. So in this post you will learn how to install a front end for UFW, Firewal Configuration (gufw), to manage and configure UFW easily in GUI mode. gufw is a simple (probably the best and fast) firewall configuration software that works! and got 5 star in Ubuntu Software Center ratings. You may need to enable (by check the square box) the universe repository in Synaptic Package Manager -> Settings ->Repositories -> Ubuntu Software .

Mac OS X Theme for Ubuntu 11.04

Mac OS X has been the most popular operating system, if we consider the look (of course! it’s good looking but not if we think in terms of Performance or Security or Features – Ubuntu is far better!); probably due to its robust – layout, design and typography; and cool charming icons (Mac OS X Leopard Icons). That’s why most of the snapshots you see in Application/software releases, uses Mac OS (with the assumption that the particular Apps/Software is supported with Mac).

On Ubuntu 11.04(Natty Narwhal), if you are using Gnome Desktop then customize it in the same way as you did in Ubuntu 10.10 (Using Macbuntu in Ubuntu 10.10 – Lucid Lynx), but it may vary if you are using Unity Desktop probably due to Unity shell/Interface. But don’t worry Gnome 2.3 themes is also supported with Unity. You just need to download the theme package (*.tar.gz) and drop it on the ‘Appearance -> Themes window’. If the package is properly configured, then it will display a message like – ‘New Theme Installed Successfully’. So in this post, you will learn – how to get mac like look on Ubuntu 11.04‘ i.e transforming Natty Narwhal to Mac using a simple theme.

kde-desktop-logo KDE ( K – Desktop Environment) is one of the most popular open source (KDE is released under LGPL) Desktop preferred by a vast majority of Linux users. Ubuntu releases special – dedicated edition with KDE desktop and named as – KUbuntu.

Canonical has made Unity, the default desktop in Ubuntu 11.04 (Natty Narwhal), and a lot of Ubuntu fans are upset about this, because They wanted to use GNOME 3.0 instead of Unity. Unfortunately the stable PPA isn’t available currently (Although in next version of Ubuntu, i.e 11.10, Gnome 3.0 will be installed by default) although you can install Gnome 3.0 Desktop/shell on Ubuntu 11.04 through PPA (Unstable), which will break the Unity; so it’s not recommended in general. In this article, you will learn how to install KDE 4.6 desktop on Ubuntu 11.04, from command Line or Synaptic Package Manager. A lot of popular Distribution uses KDE – e.g Open Suse, Linux Mint, Backtrack 4 (A dedicated Linux desktop for cyber security professionals or Ethical Hackers).

how to install NetBeans IDE on Ubuntu 11.04

NetBeans is one of the most popular Integrated Development Environment ( IDE , which provides a set of tools and features to speed up the development process, so helpful in boosting productivity of programmers). Netbeans is a free and open source Application, available for all common platforms – Linux Distors like Ubuntu 11.04 (Natty Narwhal), Fedora, Linux Mint; Windows and Mac OS X. Netbeans 7.0 (Latest Stable Version) released a week ago. Netbeans is very popular among Java EE developers, because of its features and simplicity. This post will explain how to install netbeans on a freshly installed ubuntu 11.04, from USC (Ubuntu Software Center) or shell, you can also use Synaptic Package Manager.

You can also Try Eclipse IDE on Ubuntu 11.04, if you want, as Eclipse is another very popular open source IDE, but Netbeans is recommended, for beginner programmers because it’s very simple, lightweight and easy to start. A lot of free plugins are available to extend the features (support for Ruby and Rails, C/C++, PHP etc) of Netbeans IDE. I , personally don’t recommend IDE to beginner programmers, because of the fact that – ‘IDE will hide a lot of things, by creating a layer of abstraction, that we should now’; when you are experienced enough to understand the underlying details, then go for an IDE like NetBeans or Eclipse. Nebeans got 4.5 out of 5.0 in software center rating.
