HTTP Server and Port Scanner

A multithreaded HTTP server and port scanner, did this project when I first started learning C to learn more about fundamental networking concepts and socket programming while learning C.

Features

• Multithreaded HTTP Server - Handles concurrent GET/POST requests with file serving capabilities
• Security System - Detects and blacklists IPs based on excessive connection attempts (rate limiting)
• Port Scanner - Identifies open ports on target servers
• Request Logging - Monitors and logs HTTP requests and connection attempts
• Attack Simulation - Tests blacklist functionality with simulated connection floods

How to Run

Compile

make

Start HTTP Server

./server

Server will listen on http://localhost:8080

Test GET Requests (while server runs)

Visit http://localhost:8080/test_get.html in your browser or:

curl http://localhost:8080/test_get.html --output response.html

Then open response.html to see the server's response.

Test POST Requests (while server runs)

python3 test_post.py

Test Port Scanner (while server runs)

./port_scanner

Test Blacklist System (while server runs)

./blacklist_test
