Kali Nethunter is a robust platform for penetration testing on Android. It enables security enthusiasts to conduct a range of tests and assessments right from their mobile devices. With Termux facilitating this installation, users benefit from a streamlined environment that is lightweight yet powerful for security testing. This guide breaks down the installation process of Kali Nethunter in Termux, tailored for beginners who are keen on ethical hacking.

Requirements

Before we begin, ensure you have the following essentials ready:

A fully charged device
A reliable internet connection
At least 1GB of RAM and 2GB of available storage
The Termux app, which you can find on the Play Store
NetHunter KeX from the NetHunter store
A bit of patience for the installation process

Once you have these items checked off, you're ready to proceed!

Install Termux

First, download the Termux app from the Google Play Store. This versatile terminal emulator allows you to run a Linux environment directly on your Android device.

Setup Termux

After installing Termux, open the app, and set up its storage using the following commands:

```sh

termux-setup-storage

apt update && apt upgrade

```

The first command prepares your device for storage access. The second ensures that all package lists are current, which is crucial for a smooth installation.

Install Nethunter

With Termux set up, you can now install Kali Nethunter. Run these commands:

```sh

pkg install wget

wget -O install-nethunter-termux https://offs.ec/2MceZWr

chmod +x install-nethunter-termux

./install-nethunter-termux

```

The `pkg install wget` command installs the `wget` tool needed for downloading files. Following that, the script for Nethunter installation is fetched and executed. According to data from various user forums, users report that this installation typically takes about 5 to 10 minutes depending on the speed of your internet.

Set Up VNC Password

Once the installation completes, you'll see a prompt with default credentials to access your new Kali environment (username: "kali", password: "kali").

For better security, create a new VNC password with this command:

```sh

nethunter kex passwd

```

This step safeguards your graphical VNC session, ensuring that unauthorized users cannot access your setup.

Start Nethunter GUI

To initiate the Kali Nethunter GUI, use this command:

```sh

nethunter kex &

```

This command starts the Nethunter KeX session in the background. Next, launch the Kex Client App, adjust the password if needed, and connect to your new Nethunter session. According to recent users' feedback, many find that adjusting settings in the Kex Client can enhance their experience significantly.

Stop Nethunter

When you finish your session or want to close it, use the following command:

```sh

nethunter kex stop

```

Executing this command ensures that the GUI shuts down properly, helping to free up valuable resources on your device.

Troubleshooting

Occasionally, users may face challenges during installation. If you encounter download errors during the `apt update && apt upgrade` step, try these troubleshooting tips:

Open the resolver configuration with:

```sh
sudo nano /etc/resolv.conf
```
Look for the line that states `nameserver 127.0.0.53`.
Change it to Google's DNS servers:

```
nameserver 8.8.8.8
nameserver 8.8.4.4
```

Switching to Google’s DNS has proven effective in resolving connectivity issues that may arise during installation, as seen in various user discussions.
