Network Toolkit

by mrachcore

Cyber-inspired local IT & network diagnostics toolkit built with Python and Streamlit.

---

📌 Overview

Network Toolkit is a lightweight local IT/network utility dashboard created as part of my learning journey during my Ausbildung as a Fachinformatiker für Systemintegration.

The application combines:

• network troubleshooting tools
• system monitoring
• log analysis
• simple automation

inside a modern cyberpunk-inspired interface.

The project runs completely locally and does not require:

• paid APIs
• cloud services
• Docker
• databases
• external infrastructure

🚀 Installation & Setup

Requirements

• Python 3.10 or newer recommended
• A normal local laptop or desktop
• Internet access only for installing Python packages

---

Setup

Open a terminal in the project folder:

cd network-toolkit

---

Create a virtual environment

python -m venv .venv

---

Activate the virtual environment

Windows

.venv\Scripts\activate

Linux/macOS

source .venv/bin/activate

---

Install dependencies

pip install -r requirements.txt

---

▶ Run The App

streamlit run app.py

Streamlit will print a local URL, usually:

http://localhost:8501

Open that URL in your browser.

📝 Notes

• Ping and traceroute use local operating system commands.
• On Windows, traceroute uses tracert.
• On Linux/macOS, traceroute uses traceroute.
• If traceroute is missing on Linux/macOS, the app shows a friendly error message.
• Some process information may be hidden by the operating system.
• The application safely skips processes it cannot access.
