SimplePort

SimplePort is a basic port scanner written and runs using Python

Description

This is a simple Python port scanner that allows users to input a target IP address or hostname and a range of ports to scan. The script attempts to connect to each port in the specified range to determine if it is open. If a port is open, it tries to identify the service running on that port.

Features

Scans a user-defined range of ports.
Attempts to identify services running on open ports.
Handles common exceptions such as invalid hostnames or connection issues.
Provides a timestamped summary of the scanning process.

Prerequisites

Python 3.x

Usage

Save the script to a file, e.g., port_scanner.py.
Run the script from the command line:
```
python port_scanner.py
```
Enter the target IP address or hostname when prompted.

Enter the starting and ending port numbers to define the range of ports to scan.

Example:

Enter the target IP address or hostname: 127.0.0.1
Enter the starting port number (e.g., 1): 20
Enter the ending port number (e.g., 1024): 25

Example Output

Starting scan on target: 127.0.0.1 Scanning ports from 20 to 25 Scan started at: 2025-02-11 09:32:00 Port 21: Open - Service: ftp Port 22: Open - Service: ssh Scan completed at: 2025-02-11 09:32:10

Notes

Scanning privileged ports (below 1024) might require administrative/root access depending on your system.
The timeout for each connection attempt is set to 1 second. You can adjust this in s.settimeout(1).
Use this script responsibly and only on systems you own or have explicit permission to scan.
