Kali 2.0 is named as Sana, This is the most advanced penetration testing platform we have ever made. And the good news is that it's available in 32 bit, 64 bit, and ARM flavors, as well as a number of specialized builds for many popular hardware platforms.
Below links will take you to the official download pages of Kali Linux.

Backtrack vs Kali vs Kali 2.0

I know that this title doesn't make sense, but I just want to let you know the different between these penetration platforms. Backtrack is the mother of penetration testing distros, first release of Backtrack released before 10 years. It's a debian based distro & is no longer being maintained. After Backtrack 5.0 R3, Kali was released & It's also called as the new Backtrack or BT 6. Kali 2.0 is the latest one to be released among all the three with better snappier interface, automatic updates & new Kernel.
Let's jump into the topic and proceed with the installation.


How to install Kali 2.0?

In this post, I used Vmware workstation 11 to demonstrate the installation of Kali 2.0. Below steps will guide you to create a VM in Vmware. In case if you are going install it on your base machine or if you know already how to create a VM in VMware workstation.

Open Vmware workstation software, And click Create New Virtual Machine. Typical is selected by default, Click Next.


Next you will be asked to select the ISO file, click browse window & select the downloaded ISO file.


Select the Guest Operating System type as Linux & let version to be Debian 6.


Give a proper name to your Virtual Machine, And it in a location where you have atleast 10GB free. I have named mine as Sana, A cool one isn't it?


Give the maximum disk space that you are going to allocate for thisVM, 20GB would be sufficient in my opinion. I recommend to store the VMDK file as a single file since it would be easier to move and to convert to other formats.


Click on Customize Hardware & Change your RAM, CPU and Network adapter settings if you want to.


Below snapshot shows my increased RAM size,

RIP stands on Routing Information Protocol. Lets apply RIP protocol on the following topology.

Here, we will see communication enabled between PCs via Router in Packet Tracer.
So, for this we need two PCs, a router ,and two cross over cables to connect them.
Important point is that we use cross over cable to connect PC to a router because they both use the same pins for transmission and receiving of data.



Now, we will connect them by selecting fast Ethernet interfaces on both ends.



Now, we have connect the devices. Further, we will go to the router CLI mode and enter the following commands.
Step by step ,
we will have to do the following things.
i. Access the interfaces one by one
ii. Assign IP addresses to interfaces
iii. Change the status of the interfaces i.e. from Down to Up.
iv. Assign IP addresses to PCs.
v. Assign Default Gateway to PCs. FYI fast Ethernet ip address is the gateway address to the PC. 
Now, commands of the Router CLI mode are as follows.



Now, we have accessed both interfaces one by one and we have assigned IP addresses respectively.

See the difference the lights have changed the color from Red to Green :)
Now, lets assign IP addresses to the PCs.
Click on PC1, go to Desktop, then click IP Configuration.
PC1:



PC2:




Now, our communication is enabled and we are able to communicate from PC1 to PC2 via Router.
Click on the packet in the right panel on the packet tracer, then click on PC1 and then click on PC2. You will see the successful packet tracer (status is shown in the bottom right corner)

Bingo, your communication is successful.
