This project includes both a Python-based Port Scanner script and a Bash script to perform various types of network scans on a specified IP address. Both scripts provide interactive interfaces for users to choose different scanning techniques to assess network security and discover open ports.

• Interactive Input: Users can input the target IP address and choose the desired scan type.
• Multiple Scan Types:
  1. Ping Scan: Quickly checks if the target host is online.
  2. TCP SYN Scan: Performs a stealthy TCP SYN scan to detect open ports.
  3. TCP Connect Scan: Completes a full TCP connection for port scanning.
  4. UDP Scan: Identifies open UDP ports on the target.
  5. Aggressive Scan: Performs detailed scanning with OS detection and service version detection.
• Displays:
  • Nmap version being used.
  • Host status (up or down).
  • Protocols found on the target host.
  • Details about open ports.

• Easy-to-Use: The Bash script offers a quick and straightforward way to perform similar scans without requiring Python.
• Multiple Scan Options:
  1. Ping Scan: Check host availability.
  2. TCP SYN Scan: Stealthily detect open ports.
  3. UDP Scan: Identify open UDP ports.
  4. Aggressive Scan: Includes OS detection and detailed service scans.
• Interactive Interface: Users can select scan options from a menu.

• Python 3.6+
• Nmap module: Install the python-nmap library.

  pip install python-nmap

• Nmap: Ensure Nmap is installed on your system.

  # On Linux (Ubuntu/Debian):
  sudo apt install nmap -y
  
  # On macOS:
  brew install nmap
  
  # On Windows:
  choco install nmap

1. Run the script:

   python3 port_scanner.py

2. Follow the prompts to input the target IP address and select the scan type.

1. Make the script executable:

   chmod +x port_scanner.sh

2. Run the script:

   ./port_scanner.sh

3. Follow the menu to choose your scan type and input the target IP address.

Nmap version: 7.93
Target: 192.168.1.1
Host is up (0.12s latency).
Open ports:
22/tcp   SSH
80/tcp   HTTP
443/tcp  HTTPS

Select Scan Type:
1. Ping Scan
2. TCP SYN Scan
3. UDP Scan
4. Aggressive Scan
5. Exit

Enter your choice: 2
Enter target IP address: 192.168.1.1
