Network Port Scanner

This is a Python-based Network Port Scanner designed for assessing active hosts and their open TCP and UDP ports. The program performs a scan on the specified network interface, checking for open ports and retrieving banners from services running on those ports. It was developed as a final project for the "Fundación Telefónica FTM Ed 19" cybersecurity course.

Features

• Multithreading Support: Scans multiple ports simultaneously to speed up the scanning process.
• TCP and UDP Scanning: Checks for open TCP and UDP ports, retrieving service banners if available.
• Reachability Check: Uses ping to determine if a host is reachable before scanning.
• JSON Output: Saves the results of the scan in a JSON format to a specified file.
• HTTP POST Request: Sends the scan results to a specified server endpoint.

Requirements

• Python 3.x
• Required libraries:
  • socket
  • psutil
  • ipaddress
  • subprocess
  • concurrent.futures
  • threading
  • json
  • requests

You can install the required libraries using pip:

pip install psutil requests

Usage

To run the program, use the following command:

python network_port_scanner.py -i <interface> [-t <threads> -os <OS> -u <url> -f <filename>]

• -i < interface >: The network interface to scan (e.g. eth0, wlan0).
• -t < threads >: (Optional) Number of threads to use for multithreading.
• -os < OS >: (Optional) Name of the host operative system, can be "windows", "linux", "macos".
• -u < url >: (Optional) URL of the destination server to send the scan results in json format.
• -f < filename >: (Optional) Name of the file to write the scan results in json format.

Example

python network_port_scanner.py -i wlan0 -t 50 -os linux -u "http://example.com/file.php" -f "scan_output.json"

Output

The program prints the reachable hosts and open ports to the console during execution.

Additionally, the result of the scan will be saved in a file and sent to a URL in the following format:

{
    "192.168.1.1": {
        "tcp": [
            {"port": 22, "banner": "service banner"},
            ...
        ],
        "udp": [
            {"port": 53, "banner": "service banner"},
            ...
        ]
    },
    "192.168.1.2": {
        "tcp": [],
        "udp": []
    },
    ...
}
