Lightweight Port Scanner

This Python Port Scanner is a simple tool that scans for open ports on a network. It can scan a specified range of IP addresses or random IPs for a given set of ports. This script is useful for network administrators and cybersecurity enthusiasts who need to monitor network security or identify potential vulnerabilities.

Features

• Scans specified IP range or random IP addresses for open ports.
• Customizable port range for scanning.
• Simple and easy-to-use command-line interface.

Usage

To use the Python Port Scanner, you can specify the IP range and ports via command-line arguments:

python -m src.port_scanner -r <IPRANGE> -p <PORTNUMBERS>

Arguments

• -r or --range: Specify the IP range to scan. Format: start_ip-end_ip (e.g., 192.168.1.1-192.168.1.255). If this argument is omitted, the script will scan random IP addresses.
• -p or --ports: Comma-separated port numbers to scan (e.g., 80,443).

Example

python -m src.port_scanner.py -r 192.168.1.1-192.168.1.255 -p 80,443

This command will scan the IP range 192.168.1.1 to 192.168.1.255 for open ports 80 and 443.

Output

The script outputs the results to the console, indicating whether each port on each IP address is open or closed.
