How to Make Your Ubuntu Desktop Look Like the One of Mac OS

If you are a fan of the design proposed by Apple for most of its operating systems, particularly Mac OS X, then there are a couple of things that you should take into consideration and some simple steps to follow. Therefore, you are advised to read the following information carefully in order to achieve the expected outcome in the shortest time.

There are two free pieces of software that can transform your Ubuntu desktop into one that looks identical to the one of Mac OS in no time. The Ubuntu version is called Macbuntu. First of all, you will need to install this program onto your local hard drive. Here is what you need to do for this step:

– If you are using Ubuntu 10.4 Lucid Lynx, you will need to open a new terminal and type the following lines into it:

$wget https://downloads.sourceforge.net/project/macbuntu/macbuntu-10.04/v2.2/Macbuntu-10.04.tar.gz -O /tmp/Macbuntu-10.04.tar.gz
$tar xzvf /tmp/Macbuntu-10.04.tar.gz -C /tmp
$cd /tmp/Macbuntu-10.04/
$./install.sh

– On the other hand, if Ubuntu 10.10 Maverik Meerkat or a similar version is installed in your system, you will need to use a different version of Macbuntu, which can be accessed by typing the following:

$wget https://downloads.sourceforge.net/project/macbuntu/macbuntu-10.10/v2.3/Macbuntu-10.10.tar.gz -O /tmp/Macbuntu-10.10.tar.gz
$tar xzvf /tmp/Macbuntu-10.10.tar.gz -C /tmp
$cd /tmp/Macbuntu-10.10/
$./install.sh

During the install process, you will be provided with the chance of choosing between different options. These are usually dependent on the different ways you wish your desktop to look like. Most of the choices will be based on your visual tastes, so make sure you choose according to them.

Finally, whenever you need to uninstall this special package for some reason you can follow the same procedure described above, with just an exception. Instead ./install.sh you will need to use the ./uninstall.sh command.

How to Boot Ubuntu from USB

When it comes to the most recent generation of computers, there is an option to start an operating system right from a USB stick, without an actual installation process. This may be an option to use or test a different operating system without affecting in any way the one that is already installed.

Starting from version 8.10, Ubuntu can be installed on a USB stick in a more easy way by every single user, regardless of their knowledge in Linux. To perform the installation, the user must have a version of 8.10 or later on CD and a USB stick with a capacity of at least 700 MB free space available, but this can vary according to the version of Ubuntu that you want to use for this process.

To install Ubuntu on the USB stick, you can simply boot the Live CD mode of Ubuntu or alternatively, if already installed on your on your system, you can follow the following simple procedure to do this, which is described in some basic steps below.

First of all, you need to access the Ubuntu menu bar, via System> Administration, choose Create a USB startup disk.

At this point, you will be asked to specify the source disk image of Ubuntu. If you have the Ubuntu CD in optical drive, it should appear in the list and will be selected. Otherwise, click Other and specify the location of the image. The .iso format will do it, but other versions may work as well.

When completed, you can use the stick on any computer that can boot from such units. Just tell the computer’s BIOS to use this option and restart the respective machine. The same procedure can be applied for the any distribution of Linux, so this is a helpful tutorial for everyone.

Including a Ubuntu Machine into a Windows Domain

4 Replies

One of the great problems of interoperability between Linux and Windows has been the impossibility of Linux systems for joining a Microsoft Windows network. Subsequently, several standards to achieve this were developed over the years (see Samba), but they were far from offering normal user the chance to achieve this easily.
The infrastructure of many companies around the world, of all sizes, also relies on the use of a Windows domain. In all companies, one priority always stands out. That is to reduce information costs and expenses. Because of this, many of them have opted for the use of computers with Linux operating systems. But in many cases their integration into Active Directory environments was a problem.
Recently, a new tool was created to facilitate the full integration of a Linux system in an AD environment. And as far as today, it seems very promising. Thanks to likewise-Open5 (http://www.likewiseopen.org/), the difficulty of integration is almost null.

The following lines will illustrate the inclusion of Ubuntu in a Windows domain via likewise-Open5.

Installation

Likewise-Open5 Installation process is very simple. It can be done both through the graphical environment and command line. We will use the second variant. Therefore, a new terminal window must be open, in which you specify the following command:

sudo apt-get install likewise-open5

This command should resolve all the dependencies necessary to prepare the machine to be integrated in the Windows domain.

Adding a new machine

To actually add the machine, specify the following command in the terminal window:

sudo domainjoin-cli join domain used

Where DOMAIN is the area used for integrating the machine, and USER is the username that has the corresponding rights. You will be asked for your user password, and once successfully logged in, you are officially added the desired machine.

How to Get Rid of the Root Password on Linux

3 Replies

If you are a Linux user, particularly Ubuntu, and are the only person that uses your computer, sometimes the fact that your operating system constantly requires for your password every time you log in, then at a certain moment you might want to decide to get rid of it. All you need to do is to follow the next steps carefully and you will be ready to go.

Run a new terminal. This is essential, since, as you already know, every important command and feature of Ubuntu and Linux in general must be done in this way
Run the command ‘sudo visudo’. This will at first require the current root password, as every line starting with ‘sudo’ does.
Type the root password and hit return
A new document will now open in your terminal, which will require some editing. Specifically, a new line should be added in the end of this document. This line is ‘username ALL=NOPASSWORD:ALL’. As you can guess, this will make your operating system stop asking about your root password every time you log in, regardless of the user you use for this process.
Save the edited document and make sure the changes are active.
Restart your computer and check to see whether you can log in without your root password.

As you can see, getting rid of the root password is a rather easy process and sometimes it will save you a lot of time. However, make sure you only do this if you are the only person who uses your account on your operating system, because otherwise your security will be exposed.

This password removal tweak will also work for ‘sudo’ commands as well, making it even simpler for you as a Linux user.

Some Linux security tips for Rootkit Hunter

1 Reply

If you run Rootkit Hunter and you haven’t modified your stock Red Hat configuration of the SSH service (sshd), chances are it will find that you allow root logins. Rootkit Hunter considers these as possible security risks. However, to fix this, you can simply login as root, fire up a text editor, and edit the file

/etc/ssh/sshd_config

Make the following changes:
You’ll find a commented line like this:
#Protocol 2,1
Uncomment it and change it to:
Protocol 2
This will disallow logins using the older versions of the protocol

Look for the commented line
#PermitRootLogin yes
Uncomment the line and change it so it reads:
PermitRootLogin no
This will configure sshd NOT to allow root logins.

After this, be sure to restart sshd (assuming you run the service in the first place so:
Service sshd restart
