Port-Scanner

This repository contains multiple scripts to perform port scanning on a given target. The port scanning functionality is implemented in three different languages: Bash, Python, and PowerShell. Each script supports two types of scans: full scan (scanning ports 1-65535) and half scan (scanning ports 1-1024).

Scripts

1. Bash-Scanner.sh: A Bash script to scan ports using nc (Netcat) to check for open ports.
2. PY-Scanner.py: A Python script that uses the socket library to scan the specified range of ports.
3. PS-Scanner.ps1: A PowerShell script that uses the System.Net.Sockets.TcpClient class to perform port scans.

Features

• Full Scan: Scans all 65535 ports (may take a long time).
• Half Scan: Scans ports 1-1024 (faster than a full scan).

Prerequisites

For Bash-Scanner.sh

• A Linux-based system with Bash.
• Netcat (nc) installed.

For PY-Scanner.py

• Python 3.x installed.

For PS-Scanner.ps1

• A Windows system with PowerShell.

---

• Here is the command to install the prerequisites:

sudo apt install powershell netcat-traditional python3 -y

Usage

Bash-Scanner.sh

To use the Bash-Scanner.sh script, open a terminal and run the following command:

./Bash-Scanner.sh <target> <full/half>

• <target>: The target domain or IP address.
• <full/half>: The type of scan (full for all ports 1-65535, half for ports 1-1024).

Example:

./Bash-Scanner.sh example.com full

PY-Scanner.py

To use the PY-Scanner.py script, run the following command in the terminal:

python3 PY-Scanner.py <target> <full/half>

• <target>: The target domain or IP address.
• <full/half>: The type of scan (full for all ports 1-65535, half for ports 1-1024).

Example:

python3 PY-Scanner.py example.com half

PS-Scanner.ps1

To use the PS-Scanner.ps1 script, run the following command in PowerShell:

.\PS-Scanner.ps1 -target <target> -scanType <full/half>

• <target>: The target domain or IP address.
• <full/half>: The type of scan (full for all ports 1-65535, half for ports 1-1024).

Example:

.\PS-Scanner.ps1 -target example.com -scanType full

Output

Each script will display:

• The target (both domain name and resolved IP).
• The start time of the scan.
• The type of scan and port range being used.
• For each open port, the script will print PORT <port_number> : OPEN.
