Installing Virtual Box Guest Additions in Zentyal

I stumbled across Zentyal which seemed to be quite an interesting Linux distribution. I say that as they claim to be able to replace Microsoft’s Small Business Server (SBS) and co-exist with Active Directory and Exchange.

Have a look at their website for all the features.

I wanted to install the guest additions after installing Zentyal in Oracle’s Virtual Box to run the virtual machine in full screen mode. This was not as straight forward as I though it might be. Below is a video tutorial that I created to show how to install the guest additions in Zentyal. (Watch in HD and full screen)

Also note: the links below the video are for the sites I used to get this working.

How to install the GUI for Ubuntu Server

I’m busy installing a server for my dad’s home and need a Graphical User Interface (GUI) for him to manage the server. I decided to install Kubuntu on my Ubuntu Server that I’m testing in virtual box. We are planning on getting him a Raspberry Pi running RaspBMC and the choices are OpenMediaVault or Ubuntu server to be the media server hosting his media to be streamed from.

Still deciding which way to go but here is a short tutorial on how to get the GUI installed on an Ubuntu Server after you have finished installing the Ubuntu Server Operating System.

1. After the server has booted you need to logon with the user name and password you set in the Ubuntu installation.
2. Now update Ubuntu by running: sudo apt-get update
3. After the update has downloaded the needed packages and finished the installation run: sudo apt-get install ubuntu-desktop (this will take some time to download the packages and install Kubuntu)
4. After the installation run: sudo reboot
5. Now you will load into the GUI and Windows users should be quite comfortable to use Ubuntu

Here’s a video of the test installation:


 

 


Raspberry Pi and OpenElec

Got myself a Raspberry Pi this week to replace our current media player.

Our previous media player could not connect to the home network and I had to keep copying media to an external hard drive which as you could expect an irritation to say the least. The technology world has changed quite a lot with the introduction of the Raspberry Pi. The Pi is a credit card sized computer that has HDMI, Audio, RCA, USB and LAN connections built-in to it.

Do a google search to see some of the amazing things people have done with the Raspberry Pi.

My goal was to replace the media player with the Pi and stream media from our Home Server to the CRT TV. I installed OpenElec on the SD card which is a great Linux distro if all you want is a media player with some extra functionality.

The Raspberry Pi boots straight into OpenElec XBMC without any of the normal desktop login screens etc.

I then use Yatse which is available from the Google Play Store to remotely control the media center from my Android phone and tablet.

Let’s have a look at some Pro’s and Cons before we get to the video of my OpenElec journey.

Pro’s:
1. The Raspberry Pi with the needed accessories (power supply, SD card and case) cost me less than the media player did.
2. It connects flawlessly to my home network and server. (I had to create a user account on the server for the Pi to connect and authenticate)
3. It’s small and can be hidden out of sight.
4. Boots straight into the Media Player interface.
5. It has HDMI, RCA, RJ45, 1x audio out and 2x USB connectors.
6. Anyone can set this up using the links at the end of the article and searching the net if they get stuck.

Cons:
1. WiFi worked but kept losing my network for some reason.
2. I noticed a definite speed reduction when using WiFi.
3. The Pi had some issues with DNS but after some “googling” it was actually quite an easy fix.

Error stating “Please select a root (/) partition before proceeding” when trying to install to a selected partition in Manjaro

I got my hands on a Manjaro Linux distribution today and decided to install and play with it.

I got confronted with the below error after running through the initial setup steps and trying to choose the partition that Manjaro needed to be installed to.

After trying a few things and lots of disk partitioning I found how to install Manjaro to the root partition as shown in the short video below. This would hopefully save you some time and get to installing and enjoying Manjaro.
