How to install a desktop on Ubuntu server 12.04

When you install Ubuntu Server 12.04 the default is for it to install with no desktop which is usually fine however there are times when you might want a desktop environment so today I will show you how to install one.


If you want the default Gnome 2 desktop then type:

sudo apt-get install ubuntu-desktop

For Xfce type:

sudo apt-get install xubuntu-desktop

If you fancy KDE instead then type:

sudo apt-get install kubuntu-desktop

And for something very lightweight (LXDE – one of my favourites) then type:

sudo apt-get install lubuntu-desktop

All the above commands install all the desktop addons like Evolution, Libreoffice etc so if you would rather not have them then add  –without-recommends.  So for example the default Gnome 2 command will become:

sudo apt-get install –without-recommends ubuntu-desktop

How to install .run files


Today I will show you how to install .run files.  I had to do this yesterday when I downloaded the updated hp linux drivers for my Linux Mint 13 system.  This is how I installed it.

Open up a terminal and move to to directory in which you downloaded the .run file so type:

cd /home/comtech/Downloads

Now make the file executable by typing:

chmod 755 hplip-3.12.6.run

Now type:

./hplip-3.12.6.run

Untangle Linux Gateway


I have been looking around lately at all the old hardware I have lying around and thought what could I do with it all? Media center? Web server? Hardware Firewall perhaps? Then I came across Untangle Linux Gateway and thought why not give this a try!!  Next thought was why install on the old hardware and increase my energy costs when I can install it on Virtualbox on my main Linux server instead? So I have installed Untangle Linux Firewall on Virtualbox running on a Debian 7.0 File and Print Server and below will outline how I did it.

My network looks like this:

Internet – Wireless Router – Untangle Linux Gateway – Debian 7.0 file and print server – Various Virtual machines.

I have left the wireless router outside the main network as I am only concerned with protecting my main server and virtual machines.  I will still have firewalls on any wireless clients.

First thing is to get a copy of Untangle Linux Gateway and the best place is here.  Once you have it fire up Virtualbox and add a new virtual machine.  Remember you need the following requirements during set up:

1. Create a fixed sized disk of at least 20Gb.  If you allocate a dynamic disk the installation will fail.

2.  Allocate at least 512Mb of RAM.  I allocated 1024Mb and it runs fine.

3.  Make sure you allocate 2 NIC’s for your virtual machine and set both to bridged adapter so Untangle can talk to the rest of your network.

Mount your iso in the virtual cd drive and fire up the virtual machine and then follow installation instructions.  Make sure that you set the following during installation:

When asked set the external adapter to DHCP (unless you have got a static ip address from your ISP) and verify your internet connection.  Make sure that the DNS server and gateway are on the same subnet as your host machine.  For example mine looked like this:

ip address 192.168.1.10

default gateway 192.168.1.1

dns server 192.168.1.1

*My home server is on 192.168.1.9*

Your internal adapter should be set as bridge and bridge to external.  This will allow you to use your 1 physical adapter as two virtual ones.

Once installed (it does take a while) you will be asked to upgrade your Untangle system prior to installing any Apps.  Do this as it is always important to have an up to date system.  Next download the Lite package on the rack.  This will install all the open source packages you require and personally unless you are a medium to large business all you will ever need. Once installed test your connectivity from other machines on the network and also check how secure your network is by going to ShieldsUp and using their online firewall scanner to test your firewall.

As for all the old hardware? Suggestions here please to the usual address!!

IPv6 for Windows XP


Like it or not IPv6 is coming and quickly too.  All modern operating systems have IPv6 installed and enabled by default – except Windows XP.  IPv6 is indeed installed but it is not activated.

Open up a command prompt and type:

ipv6 install

Then press enter. IPv6 is now enabled on your machine.

With the onset of IPv6 the way our computers identify each other over the internet will change.

Installing Linux software from source


You should always try and install software through your distributions package manager but there will be times that you want a particular package that is not included.  This is when you will need to install it from source.  This tutorial will show you how.

Ok download the source code for the package you want.  Open up a terminal and switch to the directory where you saved the source code.  For example, I usually save to my desktop so I would type:

cd /home/chris/Desktop

Next just check that your downloaded source code is there by typing:

ls

Assuming that you can see the file you are after we will now need to extract the contents.  Type one of the following depending on whether your file ends in tar.gz or tar.bz2.

tar -xvzf./filename.tar.gz or tar -xvjf./filename.tar.bz2

Now we change to the directory we just extracted the files to by typing:

cd (package name)

At this  point I would recommend taking a look at the ReadMe file.  It will contain any specific install instructions.  You can find it by typing:

ls

If there are no specific instructions you now configure the files by typing:

./configure

Next we build the package by typing:

make

And finally we install it:

make install
