Kali Linux is a popular open-source Debian-based Linux distribution aimed at advanced Penetration Testing and Security Auditing. With Termux, you can install and run a full Kali Linux environment on any Android device without root access, giving you access to a wide range of security tools and utilities.
What is Kali Linux?
Kali Linux is a free and open-source platform for penetration testing and security auditing. Developed by Offensive Security, it brings together a massive collection of security tools. By running it in Termux, you can harness the power of Kali Linux directly on your Android device, creating a portable hacking environment.
Educational Purpose Only
Kali Linux should only be used for educational purposes and authorized security testing. Unauthorized use of penetration testing tools is illegal and unethical. Always obtain proper permission before conducting any security tests.
Installation
Installing Kali Linux in Termux is straightforward. Follow these steps carefully, copying and running each command one by one.
How to Use Kali Linux
After the installation is complete, you need to update the Kali Linux environment. This is a crucial step.
Important First Step: Update Kali
Before using any tools, you must update and upgrade the Kali terminal. This process can take 30-45 minutes to complete, depending on your internet connection and device performance.
Once updated, you can use the following commands in your Termux terminal to manage your Kali Linux instance:
Using GUI Desktop Mode
You can use Kali Linux with a full graphical user interface (GUI) by using a VNC (Virtual Network Computing) server. To do this, you'll need the NetHunter KeX application.
After installing the KeX app, run these commands inside your Kali Linux terminal (e.g., after running `startkali`):
Customizing the Terminal
To give your Kali Linux terminal a more attractive and functional look, you can replace the default configuration file. You can also disable the initial developer message.
Custom Bash Configuration
These commands will download a custom `bash.bashrc` file, replace the default one, and install `figlet` for awesome ASCII art text.
Disable Developer Message
To disable the message that appears when you start Kali Linux, run the following command inside the Kali root session (`startkali -r`):
