The RedHat security team have released details of a flaw which has been discovered in the BASH shell.


Updates should be coming rather quick for this issue so keep checking your systems for available security updates.


If you’d like to check if your system is currently vulnerable run the following command – courtesy of the Fedora Magazine

Installing Oracle’s VirtualBox-4.3 in Fedora 20

Whilst I tend to use Virt-Manager for my Virtualization needs, numerous users choose Oracle’s offering of VirtualBox.

Especially users that maybe coming from Windows.


Firstly VirtualBox need’s a few packages installed before we start the main installation.



[alert-note]Please su into root or use sudo[/alert-note]

yum install kernel-headers kernel-devel dkms


Add Oracle’s Repository File

Change into Yums repo directory

cd /etc/yum.repos.d

then create the new repository file

touch virtualbox.repo

Edit the newly created file and copy and paste the following text and save the file.

name=Fedora $releasever - $basearch - VirtualBox
gedit /etc/yum.repos.d/virtualbox.repo

Now all we need to do is install VirtualBox-4.3 by doing the following

yum install VirtualBox-4.3

VirtualBox-4.3 will now install. All you need to do is now spin up a new VM of your choosing, have fun!

Installing it doesn’t have to be a hard task and it’s even easier thanks to Slaanesh over at http://www.negativo17.org

RHEL/CentOS 7 – x86_64


To Install –  [alert-note]You must be root![/alert-note]

Firstly we need to add the repository that Slaanesh has created for all his packages.

Beats Audio Subwoofer Not Working Correctly – Ubuntu 14.04

Quite a few brands of laptop come with beats audio hardware these days. My actual model is a HP Envy 17″.

When I first installed Ubuntu 14.04 I noticed the sound was very tinny and just didnt sound right at all, then I figured out that the sound wasn’t actually coming out of all the speakers on the laptop.

The only solution that I have found so far is to retask the audio using “HDAJackRetask” which is part of the “alsa-tools-gui” package.


Fire up a terminal and install the package we need by doing –

sudo apt-get install alsa-tools-gui

Once installed head over to the dash and start typing HDA until you see the Icon for HDAJackRetask appear then run the application.

Once ran, select your codec and stick a tick in the box which says “Show Unconnected Pins” and just copy my configuration from the screen shot below.

HDA Jack Retask

Click Apply now to test, You should see that the sound is a lot better than before. Once you’re happy with it hit “Install Boot Override”

Hope this helps someone, if you know of any other way to get this working please comment I’d love to hear your solutions.

This guide also works within Fedora 20.
