Port-Scanner

A multithreaded TCP port scanner written in C++ using WinSock2 and a custom thread pool.

It scans ports 1–65535 on a given IPv4 address by attempting a TCP connect() to each port. Open ports are identified when the connection succeeds.

Design

• RAII-based WinSock initialization
• Fixed-size thread pool
• Chunk-based port distribution
• Thread-safe result aggregation

Configuration

• Port range: 1–65535
• Work chunk size: 1024 ports per task
• Maximum worker threads: 8
