How-to setup a simple UFW firewall on Ubuntu

We all need to install some form of firewall to secure our systems from any malicious activity. Not just our servers and VPS machines, but also our laptops which we access on public networks. UFW (Uncomplicated FireWall) is an ideal solution for setting up a firewall on your system.

UFW firewall is completely open source and is actually built on top of the iptables making it easier for us to manage and run the firewall.

This is the third article in the series on “Systems Security”. Here we discuss UFW firewall implementation on your system. The articles in the System Security series are listed below.

How-to Disable Password Authentication on Linux

This how-to will explain how to disable password based authentication on Linux based systems. It is in continuation of our series on System Security. With the first one published on SSH keys based authentication. We wrote this as a lot of you sent us messages, on social media, to add tutorials on how to secure the server by disabling the password based authentication.

We recommend that the administrator should not attempt to disable password based authentication unless SSH keys are correctly setup and users can easily login using that method.

Three amazing Ubuntu Distros of Linux for 2017

We all love Ubuntu. It has over the course of past twelve years become one of the most popular Linux Desktop Distribution in the world. In this time it has also spawned a whole generation of amazing Ubuntu distros based upon it.

Over the past many years, we have tested many of them. Some were really short lived, like GOS that we reviewed back in the day. But others, like ZorinOS, have survived and grown tremendously and have built a strong following of their own.

How to Install Microsoft Exchange Support for Evolution Mail Client

Connecting to Microsoft Exchange is never that easy. Especially, if one is trying to do it using open source and free softwares. There are plug-ins to be installed and configured, additional libraries to be installed. And it gets murkier as Exchange also has many versions (Pre 2007 is not web services based). In short, it requires a bit of tinkering on a Linux platform.

Evolution, by Novell is an excellent mail client. It offers not only mail, but calendaring, note taking, address book management and many other features offered by the popular MS-Outlook. What’s more, it even looks like Outlook. Hence, it is ideal software for those migrating from Windows desktop to a Linux. However, and some odd reason (maybe licensing issues) it does not support Microsoft Exchange out of the box. One has to install the drivers/plug-ins to get it going.

Like many others, I have struggled to get the plug-ins going for Exchange. Especially the off-the shelf versions do not always work perfectly. However, I have found one recent guide available online that gets the work done in matter of minutes. And yes, exchange works fine after that.

ExRatione has done an excellent job in putting together a script and a guide to install evolution from scratch with full support for MS-EWS (Microsoft Exchange Web Services). Use this guide to get it going and you will not be disappointed.

Linux MintBox a Mini Linux Desktop

Don’t have time to configure Linux onto your old Windows PC? Still struggling with device drivers and module compilations? Are you seeking an affordable, small and ready to use computer but not sure what is great for your browsing and email needs? Well Linux Mint might have an answer for you in the form of a mini computer, called MintBox.

The computer is not much larger than your standard wifi router. Infact, from a distance, it resembles a typical wifi router. But in reality it is a full fledged computer running the latest iteration of Linux Mint (currently in Version 15). It comes in two models Basic and Pro. The major difference between the two is the processor, RAM and GPUs. But otherwise, they are identical.

ZorinOS – Gateway to Linux for Windows Users

Linux OS currently has one of the largest selection of desktop environment options that any OS has ever had in their entire life. ZorinOS is yet another derivative of the popular Ubuntu Distro and is currently in Version 7. It is based on Ubuntu 13.04 thus offering the latest of what Ubuntu has to offer to the Linux community. But the look and feel is classic Windows 7.

One of the major and at times genuine concerns of new Linux users is that they want the same desktop/interface and the same set of software applications as they are used to on their Microsoft Windows platform. A tough ask, as even MacOS is struggling to offer all that is Windows.

Choosing the Right Linux

There is no right or wrong Linux. When choosing the right Linux, all are equally good. What differentiates one from the other is how you plan to use it and the context in which it is being used.

Say, if you want to tinker with some cool Linux derivative for fun, then by all means, install any and enjoy to your fullest. But if your motives are a bit more serious and you want to use one as your standard desktop, or have an ambitious plan to support multitude of computers running a single version of Linux then you might want to do some thinking before selecting the right Linux distribution.

The Vibrant Open Source Smartphone OS Market

The mobile OS market is only getting more awesome with each passing year. There are new players on the horizon challenging the might of Google’s Android and Apple’s iPhone. And almost all of them are based on Linux and are designed around an open source philosophy.

Just like the Linux desktop, they will all surely inspire many derivatives with interesting designs, wonderful UIs and innovative hardware specifications.

Currently, Ubuntu is ranked number one on the open source desktop environment by a long margin. Currently enjoying over 20 million active users. It has also inspired countless derivatives, some of them are extremely popular themselves, like Linux Mint, with the user community.
