KVM: Kernel Virtual Machine

26 Oct

We have been looking forward for a replacement of Virtualbox OSE . This thing started our quest for finding a Virtualization application to fulfill the needs with an easy-to-use procedure. We found KVM in Add/remove while we were looking for something alike YaVM – Yet another Virtual Machine (An application developed for openSUSE in 2006 to serve as basic virtual machine that comes with the os preinstalled). Xen , the geeky Virtual machine by SUSE linux enterprise is a virtualization powerhouse. While Xen offers quite complex procedure requiring you to boot a patched Xen kernel to create and run a Virtual machine – KVM is a loadable module which runs with the OS’s default kernel module.  The only thing it requires is that your processor should have the architecture to support visualization .

For this type:

kvm

in the terminal and see the result:

QEMU PC emulator version 0.9.1 (kvm-84), Copyright (c) 2003-2008 Fabrice Bellard
usage: qemu [options] [disk_image]

If you see the above message, then you should be smiling as you are green to go for virtualization with your hardware.

But if your CPU does not, in fact support Hardware virtuallization, you will get output such as the following:

$ kvm
Could not initialize KVM, will disable KVM support
Ubuntu does not support running KVM without hardware acceleration. Sorry.

So lets start our work with Virtualization  weapons at hand. First,  head on over to the KVM HOME PAGE

Best feature of KVM is that it is part of the OS and is not dependent upon a 3rd party vendor . Also, it’s very easy to maintain as you update your system, and load new kernel revisions, as the module will not break  like VirtualBox and VMware solutions would. Also, it’s far less problematic to manage than Xen, which is entirely unsuitable for a desktop system IMO . KVM really is more of a direct competitor to Xen than to a workstation solution like VirtualBox or VMware workstation, and has some very powerful features, I will never tap into here on my home system. By design however, it’s far less intrusive on a standard Linux desktop than Xen.

Now we have our kernel module working properly and rest everything in place so must get back to business . I will use Kubuntu for the testing purpose coz its my personnel favourite and it very light too.

Follow these steps to set up your virtual Machine :-

Game On: Wolfenstein Enemy Territory

08 Oct

Wolfenstein : Enemy Territory is a first person shooter(FPS) action multiplayer game created by Splash Damage Corp. based upon reaction time , skills and strategy gaming. Its more like the other FPS games available these days in the market but what makes is different is its various Soldier classes , better graphics, kickass game modes and experience which you gain in the game.Enemy Territory was originally planned as an add-on for Return to Castle Wolfenstein, but soon became it’s own game, a separate entity with full single player, multiplayer, AI opponents and teammates. W: ET is a free, stand-alone multiplayer only product, which means it’s for online play only, but all you need is what you download.Featuring multiplayer support for up to 32 players, Wolfenstein: Enemy Territory is the ultimate test of communication and teamwork on the battlefield.

Wolfenstein Enemy Territory

There are basically two teams : Allies and Axis (derived from WW II) .There are six officially released maps (North Africa Campaign: Gold Rush, Siwa Oasis, and Seawall Battery; Europe Campaign: Rail Gun, Wurzburg Radar, and Fuel Dump ).On each map, the offense needs to complete a certain set of objectives within a limited amount of time. The defense needs to keep the offense from completing objectives until time runs out. Some objectives may be optional, and some objectives can be carried out by either team.

There are some special classes of soldiers with different skills and strengths. Your skills will also improve as you advance in the game gaining experience called XP in game by your kills.  They are :

  • Soldier : T he soldier is the only class that can use heavy weapons. They are: mortar, portable machine gun (MG42), flamethrower, and bazooka/Panzerfaust(sniper rifle).
  • Medic : The medic has the unique ability to drop health packs, as well as revive fallen players with a syringe.
  • Engineer : The engineer is the only class which comes equipped with pliers, which can be used to repair vehicles, to arm/defuse (dynamite or land mines), or to construct (command posts, machine-gun nests, and barriers).
  • Field ops : The field ops is a support class which has the ability to drop ammo packs for other players, as well as call air strikes  and artillery strikes .

Securing your files from unauthorised access with Ubuntu

05 Oct

We are all paranoid about our files. Aren’t we? Whether if they contain personal information or classified information, there is a certain degree of concern we have. However with the advent of digital age, it is not that we can simply put them in lockers and guard them. Indeed you can lock your PC and disconnect it from network access, but what’s the point of using a computer to store your documents, use paper then right? Encrytion provides the way by which we can protect our files and folders. It is a method of encoding the files so that they can’t be accessed without being decoded first. For this we need a pass phrase (read: password). Thus the goal to stop the unauthorised individuals from accessing your critical documents is achieved. Ubuntu allows encryption and decryption of files and folders, but Ubuntu (at least the latest versions) have the ability to create an encrypted file store in which files are automatically encrypted and the process is entirely invisible from the user’s perspective.

Create an Encrypted private/ directory

Ubuntu has the ability that allows encryption of files “on the fly”. With this method, only the user who’s home directory the ~/private directory is residing, can access those files. No body else can access those files. That is a certain loophole of users being able to use a Live CD for accessing the files is largely eliminated. Now in order to go further, you need to install the required packages. I would suggest using the terminal since that would be quicker. :p

sudo apt-get install ecryptfs-utils

Now set up the pass phrase such by running this command.

ecrpytfs-setup-private

You would be asked your login password for running this command. Next it will ask you the pass phrase, i.e. the mount pass phrase. Keep in mind that the mount pass phrase is not same as login password and also that you have to remember the passphrase in case you need to unlock the files manually at a future date. Once you have finished running the commands, log out and then log back in again. After logging in, you’ll find on opening the home directory that there’s a new private folder. This private folder will store all the files within itself encrypted and thus the files within it cannot be accessed without authority, i.e. only the original user can access it.
