Port Scanner Python Script

Overview

This Python script is designed to perform a port scan on a specified target host IP address within a given range of ports. It uses TCP connections to check for open ports and reports back the open ports found during the scan.

Requirements

• Python 3.x
• Standard library modules: socket

Usage

1. Clone or download the repository containing the script.
2. Navigate to the directory containing the script in your terminal or command prompt.

Running the Script

To run the script, execute the following command:

python port_scanner.py

Input

• Target Host IP Address: Enter the IP address of the target host. For example: 192.168.1.1.
• Port Range: Enter the maximum port number to scan. The script will scan ports from 1 to the specified maximum port number.

Output

The script will display a message for each open port found during the scan, indicating that the port is open.

Input target host IP address. Example: 10.0.12.123
192.168.1.1
How many ports do you want to be scanned? Enter a number from 1 to 65,535.
100
Port 80 is open
Port 443 is open

Port Scanning is Complete.

Notes

• This script uses TCP connections to determine open ports. It may not accurately detect UDP or stealthily closed ports.
• For comprehensive network scanning or more advanced features, consider using specialized tools such as Nmap.
• Input validation needs to be added.
