Nicholas Brown - Nmap7: From Beginner to Pro

Nmap is available on the https://Nmap.org/download.html directory. One should download the right version based on the operating system they are using. The installation steps for Nmap are also different for the different operating systems. For the case of Windows, you have to download the .exe file with the Nmap tool then double click it so as to begin executing it. You will first be asked to agree to the licensing terms:

Next, you will be asked to choose the features which should be installed. It is good for you to leave it at the default setting then you click on Next:

In the next window, choose the directory in which you want to install the Nmap then

Click Install. The installation process will begin right away.

Note that the Nmap for Windows is not as efficient as the Nmap for Linux. Let us demonstrate how the Nmap can be installed and updated on the earlier versions of Kali Linux.

Before performing the update, first ensure that you have all the repositories in place. The following command can help you verify this:

cat /etc/apt/sources.list

The official repositories for Kali Linux 2.0 include the following:

deb http://http.kali.org/kali sana main non-free contrib

deb http://security.kali.org/kali-security sana/updates main contrib non-free

deb-src http://http.kali.org/kali sana main non-free contrib

deb-src http://security.kali.org/kali-security sana/updates main contrib non-free

The repositories for the older versions include the following:

deb http://http.kali.org/kali kali main non-free contrib

deb http://security.kali.org/kali-security kali/updates main contrib non-free

deb-src http://http.kali.org/kali kali main non-free contrib

deb-src http://security.kali.org/kali-security kali/updates main contrib non-free

If you dont have the above, then you can copy them and add them to the file sources.list which can be found in the /etc/apt/ directory. You can then update the package database for the OS by running the following command:

apt-get update

The update will take some minutes which will be determined by the number of updates to be done and the speed of your internet connection. Once the update is completed, you will be ready to install a newer version.

You only have to install the Nmap again. Using apt-get ill update the version you have to the latest version:

apt-get install Nmap

After the installation completes, verify the version that you have by using the V option as shown below:

Nmap V

Now that you have updated the Nmap package, you can go ahead and update the zeNmap package. To do this, launch the terminal then run the following command:

apt-get install zeNmap
