Installing Kali Linux 1.1.0

1. First go the download page of Kali Linux at below address and grab the latest version of Kali Linux ISO file for your system architecture.

1. https://www.kali.org/downloads/

2. After downloading, either burn the downloaded ISO image to CD/DVD drive, or prepare a USB bootable stick with Kali Linux Live as the installation medium. If you don’t know how to make an USB as bootable stick, read the article that shows how to install Linux from USB.
3. To start the installation process, boot the Kali Linux with your chosen installation medium CD/DVD or USB. You should be presented with the Kali Boot screen. Select either Graphical or Text mode installation. In this example, I’m going to choose graphical installation.

 .

4. Choose your respective language for the installation and then your country location, this should be location were you live. You will also need to configure your keyboard language with correct keymap.

5. By default it will configure the Network, if you have a DHCP server from router or from our local dedicated DHCP server. If not, you have to assign the IP and host name as follows.

Here I’m going to choose manual configuration, select Configure network manually and click Continue to provide the IP address with Netmask in the format of IP Address/Netmask 192.168.0.155/24.

6. Next, provide the gateway IP address of the default router. If you don’t have a router, in this case you can leave this blank or consult your network administrator to configure it. Here I am using my gateway router IP address 192.168.0.1.
 
7. Now enter the IP address of your Name Server (DNS), if you don’t want to use any name servers, you can leave this option has blank. Here in my case, I’ve local DNS, so here I am placing my DNS Server’s IP address as my name server.

8. Next, enter the hostname for your Kali Linux installation, by default it set to Kali as hostname, but here I’ve used the same hostname as “Kali“, but you can choose whatever you want…

9. Next, set the domain name if you have one or leave blank and click Continue to move forward.

10. On the next screen, you need to set a password for root user, it’s always a good practice to use mixture of letters, numbers and special characters in passwords and should be changed on regular intervals to protect your servers.
