Network security is an ever growing need these days. You never know what you’re going to find when you step out into the wild world of the internet. Luckily we’re all using Ubuntu so we’re much more protected than most of the world, but there still is reason to protect our computers and networks.

For those of you that are not behind a hardware router (if you don’t know this might be you) you definitely want to install a firewall for your system.

Setup a Desktop Firewall with Firestarter : Ubuntu (5.10 / 6.06.1 / 6.10)

And: Using Firestarter


Skype is a little piece of software that lets you make free calls to anyone else on Skype, anywhere in the world. And even though the calls are free, they are really excellent quality. If you and your friends, family or business contacts are using webcams, you can also make free video calls. You can even call landlines and mobile phones at really cheap per minute rates (and there’s no setup or subscription fee).

Install skype in ubuntu

First you need to download the latest .deb package from here using the following command:

As part of my work on Xen I've been playing with Xephyr (a replacement for Xnest). My plan is to use Xen instances for running different versions of desktop environments. You can't just ssh -X to a Xen image and run things. One problem is that some programs such as Firefox do strange things to try and ensure that you only have one instance running. Another problem is with security, the X11 security extensions don't seem to do much good. A quick test indicates that a ssh -X session can't copy the window contents of a ssh -Y session, but can copy the contents of all windows run in the KDE environment. So this extension to X (and the matching ssh support) seem to do little good.

One thing I want to do is to have a Xen image for running Firefox with risky extenstions such as Flash and keep it separate from my main desktop for security and managability.

When you install a dual-boot of Ubuntu, one of the frustrating things that you’ll immediately notice is that Ubuntu is now set as the default operating system in the Grub loader. There’s an easy way to switch back to using Windows as the default.

To make this change, you’ll first have to boot into Ubuntu, and then run the following command:


Set Windows as Default OS when Dual Booting Ubuntu


This article is about resizing ext3 partitions without losing data. It shows how to shrink and enlarge existing ext3 partitions and how to merge two ext3 partitions.

I have mp3 music file all over my file system. I’d like to move them onto specific directory called /mnt/mp3. So how do you find and move all mp3 files to /mnt/mp3 directory?

Simply use find command. It locates all files and then executes a command to move them to /mnt/mp3 (any other directory).

A quick note for anyone wondering how to enable core dumps from within most Linux distributions.

Staying in front of your computer for hours and hours with the default fonts can be a challenge on Linux/Unix. I, for one, can't work properly without the Windows fonts comfort Smile

Having the windows fonts working on Unix systems is fairly easy, but on Red Hat-based operating systems such as CentOS or Fedora, can be a real nightmare. The most critical aspect of having the Microsoft fonts to display properly on CentOS in compiling freetype with bytecode interpreter enabled. Let's go through this procedure.

A man with his Fingers in many millions of pies

At the time of writing, over five million Raspberry Pis have been sold. That’s the same as the number of ZX Spectrums sold in the 80s. And like the Spectrum, the Pi is likely to have a far-reaching legacy, helping the next generation of games designers and computer scientists find their feet. Countless numbers of people have helped make this happen, but Eben Upton has been there from the beginning. He’s the founder and the CEO of the Raspberry Pi Foundation, and he’s still shaping every aspect of the Raspberry Pi, from its hardware to the software. We met Eben shortly before the launch of the model 2. He told us about the effort they’ve put into making the Pi better and how a chance conversation with the boss of Google shaped the Pi’s future.
