Fixing the Nokogiri/Gumbo Build Error on Termux (Metasploit 2026)

🚀 Fixing the Nokogiri/Gumbo Build Error on Termux (Metasploit 2026)

If you've tried installing Metasploit on Termux recently, you've likely hit the wall with Ruby 3.4.0. The automated build for native extensions like nokogiri fails because it can't find nokogiri_gumbo.h.

🛠 The Problem

The error fatal error: 'nokogiri_gumbo.h' file not found occurs because the Termux environment doesn't correctly pass temporary build paths to the compiler during a standard bundle install.

💡 The Professional Solution

My latest project, Metasploit-Termux v2.5.0, automates a manual "Header Injection" technique. It unpacks the gem, injects the missing C-headers into the $PREFIX/include path, and forces a manual compilation before Bundler even starts.

📦 Quick Installation

pkg update && pkg upgrade -y
pkg install git -y
git clone https://github.com/h4ck3r0/Metasploit-termux
cd Metasploit-termux
chmod +x metasploit.sh
./metasploit.sh

Turn Your Android Terminal Into a Pro Hacker Console

H4Ck3R — Thu, 15 Jan 2026 00:33:05 +0000

Turn Your Android Termux Into a Pro Hacker Console 🚀

Let’s be honest, the default Bash prompt in Termux is pretty boring. It works, but it doesn’t feel inspiring.

If you use Termux on your Android device for development, ethical hacking tasks, or just managing servers on the go, why staring at a plain screen?

I built a tool called Termux-banner to automate the process of turning that dull terminal into something that looks straight out of Mr. Robot or Watch Dogs.

What it does

It’s not just about ASCII art. This script automates the setup of a powerful Zsh environment.

⚡️ Instant Zsh Setup: Installs Oh My Zsh, auto-suggestions, and syntax highlighting automatically.
🎨 13+ Themes: Choose from styles like Cyber Dashboard (with real-time RAM/Storage stats), DedSec skulls, Glitch protocols, and more.
👤 Dynamic: You enter your name once, and it's embedded into the art.
🔰 No Root Needed: Works on any standard Termux installation.

Quick Install

If you want to try it out fast, just run these commands in Termux:

pkg install git -y
git clone https://github.com/h4ck3r0/Termux-banner
cd Termux-banner
chmod +x *
bash requirements.sh

Run option 1 first for setup, then option 2 to choose your banner.

The Full Walkthrough

While the installation is straightforward, I've written a complete, in-depth guide that explains exactly what the script does, previews all the available designs, and provides troubleshooting tips.

How To Run Ollama In Android (Without Root)

H4Ck3R — Thu, 24 Jul 2025 15:12:15 +0000

Yes, you can run Ollama directly on your Android device without needing root access, thanks to the Termux environment and its package manager. This turns your smartphone into a portable powerhouse for running local large language models (LLMs). 🚀

Read Full Post

Prerequisites

Before you start, you'll need two things:

A modern Android device. Performance will heavily depend on your phone's RAM and processor. A device with at least 8 GB of RAM is recommended for a smoother experience.
The Termux application. It's crucial to install it from F-Droid, as the version on the Google Play Store is outdated and no longer maintained.

Installation and Setup Guide

Follow these simple steps to get Ollama up and running.

1. Install and Update Termux

First, download and install Termux from the F-Droid app store. Once installed, open the app and update its core packages to ensure everything is current.

pkg update && pkg upgrade

You will be prompted several times during the update; it's generally safe to answer with the default option, which is often 'Y' or 'N'.

2. Install Ollama

With Termux up to date, installing Ollama is as simple as running a single command. The Ollama package is now available in the official Termux repositories.

pkg install ollama

This command will download and install the Ollama server and command-line interface (CLI) on your device.

3. Run the Ollama Server

Ollama operates as a background server that manages the models. You need to start this server before you can run and chat with an LLM. It's best practice to run this in its own dedicated Termux session.

Open Termux and start the server:

ollama serve

You'll see some log output, indicating the server is running. You need to keep this session open. You can use the termux-wake-lock command before this to prevent your phone from killing the process when it sleeps.

4. Download and Run a Model

Now, open a new Termux session by swiping from the left edge of the screen and tapping "NEW SESSION". In this new terminal, you can interact with the Ollama CLI.

To download and start chatting with a model (for example, Mistral), use the run command:

ollama run mistral

The first time you run this command, it will download the specified model, which might take some time and storage space. Subsequent runs will be much faster. Once downloaded, you can start chatting with the model directly in your terminal!

Important Tips

Model Size Matters: Mobile devices have limited resources. For better performance, start with smaller models like Phi-3 Mini, TinyLlama, or Gemma:2b. Running larger models like Llama 3 8B might be slow or crash if your phone doesn't have enough RAM.
Storage Space: LLMs are large files, often several gigabytes. Ensure you have enough free storage on your device before downloading models.
Keep it Running: Android's battery optimization can be aggressive. Use the termux-wake-lock command in the server session to prevent Termux from being shut down.

Predicting Crop Yield using Machine Learning

H4Ck3R — Fri, 02 May 2025 16:58:42 +0000

Sure! Here's a DEV.to style blog post for your project Crop Yield Prediction:

🚜 Predicting Crop Yield using Machine Learning 🌾

An ML project to empower smarter agriculture decisions
GitHub Repo →

📌 Introduction

Agriculture remains the backbone of the Indian economy, yet farmers still face unpredictable yields due to varying environmental and input conditions. To tackle this issue, I built a machine learning model that predicts crop yield based on historical and input-based features.

This project is simple, beginner-friendly, and practical.

🧠 Problem Statement

"How can we accurately predict crop yield based on inputs like rainfall, fertilizer, and pesticide use?"

Farmers often rely on experience or guesswork. This model helps bring data-driven decision-making to the field.

📊 Dataset Overview

The dataset includes:

Area
Production
Crop Year
Rainfall
Fertilizer
Pesticide

📌 Categorical features are label-encoded for model compatibility.

🛠️ Tech Stack

Python 🐍
Pandas & NumPy
Scikit-learn
Matplotlib (optional for plots)

🧪 Models Used

I trained and evaluated three regression models:

Linear Regression
Random Forest Regressor
Gradient Boosting Regressor ✅ Best performer

Evaluation Metrics:

R² Score
Adjusted R²
RMSE

Gradient Boosting gave the highest R² score on the test set and was chosen as the final model.

🖥️ Interactive Prediction Interface

The script allows users to input values for the features and get instant yield predictions.
✅ Handles feature consistency
✅ Uses the trained model and encoders

🚀 Try it Out!

Clone the repo and run the script locally:

git clone https://github.com/h4ck3r0/crop-yielding-prediction
cd crop-yielding-prediction
python main.py

🌱 Future Improvements

Add UI with Streamlit or Flask
Integrate with real-time weather APIs
Visual analytics for predictions

⭐ Final Thoughts

This is a practical application of ML in solving a real-world agricultural problem.
Feel free to fork, contribute, or reach out for collaboration!
