Basic Port Scanner

This project now includes two versions of the same idea:

• port_scanner_gui.py: a desktop GUI made with Tkinter
• app.py: a deployable web app made with Streamlit

Both versions demonstrate basic network reconnaissance by checking whether selected TCP ports are open or closed on a target host.

Features

• Scan common ports like 21, 22, 80, 443, and 8080
• Scan a custom range of ports
• Scan a custom comma-separated list of ports
• Show open and closed TCP ports
• Built with Python sockets

Run locally

Desktop version

python3 port_scanner_gui.py

---

Web version

Access the deployed web app at: https://port-scanner-basic.streamlit.app/

pip install -r requirements.txt
streamlit run app.py

Cybersecurity concept

Port scanning is part of network reconnaissance. It helps identify services exposed on a system before deeper security testing begins.
