Python TCP Port Scanner

A Simple Multithreaded Port Scanner built using Socket.

It was made to understand :

• TCP Connections.
• Network Scanning.
• Open and Closed ports.
• Services on each ports.
• Socket Programming.
• Multithreading in Python.
• Service Detection.
• Banner Grabbing.
• Error Management
• Working with json Files.

Features Include :

• Scan Real Time custom port ranges.
• Can Scan all the 65535 Ports.
• Proper Error Handling Included.
• Multithread support that provide fast results.
• Service Detection for all the 65535 ports.
• Banner Grabbing for Open Ports.
• JSON Export of the Open Ports

Technologies Used :

• Python 3.14.2
• Socket Module
• Threading Module
• Sys Module
• Argparse Module
• Colorama Module
• JSON Module

How it Works :

It First takes several inputs from the user like - IP Address & Range of ports i.e. Starting Port and Ending Port. Note - Supports Provide IPv4 address only.

Then it Attempts to connect on each port which is in the range of Start Port to End Port on the provided IP address.

• If Connection Succeeds -> Port {Number} is OPEN :
• If Connection Failed -> Port is CLOSED
