A fast, lightweight TCP Port Scanner built in Python. Maps open ports on any target host by scanning a user-defined port range using concurrent threads for maximum speed.
This tool performs TCP connect scans to identify open ports on a given host. Built with Python's socket and threading libraries, it efficiently scans large port ranges and logs results in real time.
- TCP port scanning — checks open/closed/timeout status for every port in range
- Concurrent scanning — uses threads for fast, parallel port checks
- Flexible input — scan a single port or a full range with custom start/end values
- Result logging — prints and logs open ports with exception handling for timeouts and errors

Log & Print Result
Each port is tested by attempting a TCP handshake. If the connection succeeds, the port is marked open. Refused or timed-out connections are marked closed or filtered.
