Nmap Scanning Tool (main_v1.7.py)

Interactive wrapper around Nmap that makes common scans quick to run and easy to read. It prints a banner, asks for a target and ports, lets you choose a scan type (SYN, Aggressive, OS Detect, NSE vuln checks, and more), and can optionally show only the lines that contain open ports.

Note: This tool executes the local nmap binary. You must have Nmap installed and available on your PATH.

Features

• Target + ports prompt (single port, range like 1-1000, or leave blank for all 1-65535)
• 12 ready-to-use scan profiles:
  1. SYN (stealth) scan -sS + OS detect -O
  2. Aggressive scan -A (OS + services + scripts + traceroute)
  3. Service/version detection -sV
  4. NSE vulnerability scan --script=vuln
  5. Heartbleed test --script=ssl-heartbleed
  6. HTTP security headers --script=http-security-headers
  7. HTTP SQL injection test --script=http-sql-injection
  8. SMB vulnerability scan --script=smb-vuln*
  9. SSL/TLS ciphers --script=ssl-enum-ciphers
  10. Service discovery (default NSE set) --script=default
  11. OS detection only -O
  12. Custom: you type additional Nmap args (e.g., -sU -T4 --top-ports 200)
• Optional output filter: show only lines that contain the word "open"
• Helpful checks and messages:
  • Warns if you’re not running with Administrator/root when some scans may need it
  • Verifies that Nmap is installed and in PATH, with OS-specific tips

Requirements

• Python 3.8+ (tested with Python 3)
• Nmap installed and on PATH
  • Windows: https://nmap.org/download.html (use the official installer, then restart the terminal)
  • Linux (Debian/Ubuntu): sudo apt install nmap
  • Linux (RHEL/CentOS): sudo yum install nmap
  • macOS (Homebrew): brew install nmap
• Python packages: pyfiglet, termcolor

Quick start

The script you run is main_v1.7.py in this folder.

Windows (PowerShell)

Optional, but recommended: create and use a virtual environment.

# Optional: allow the current PowerShell session to run the venv activation script
# (only needed if you see an execution policy error)
Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned

# Create and activate a virtual environment in .venv
python -m venv .venv
.\.venv\Scripts\Activate.ps1

# Upgrade pip and install dependencies
python -m pip install --upgrade pip
python -m pip install pyfiglet termcolor

# Run
python .\main_v1.7.py

Alternatively, if you prefer a requirements file, create one with:

# Optional alternative
python -m pip install -r requirements.txt

Linux / macOS (Bash/Zsh)

python3 -m venv ~/myvenv
source ~/myvenv/bin/activate
python -m pip install --upgrade pip
python -m pip install pyfiglet termcolor
python main_v1.7.py

Usage flow

1. Enter target IP or hostname: 192.168.1.10 or scanme.nmap.org
2. Enter port or range (or leave blank for all 1-65535)
3. Choose a scan type (1–12)
4. Choose whether to filter and show only lines containing "open"
5. Read the output; warnings (if any) are shown after the main results

Examples

• Fast service/version scan on top 1000 ports:
  • Select scan type 3 (Service Version Detection)
• Broad vulnerability sweep:
  • Select scan type 4 (NSE vuln scripts)
• Custom UDP-focused scan:
  • Select 12 and enter: -sU --top-ports 200 -T4

Privileges and permissions

• SYN scans (-sS) and OS detection (-O) often require elevated privileges
  • Windows: run PowerShell as Administrator
  • Linux/macOS: run with sudo if the script warns about privileges
• If a scan fails or shows very few results, try rerunning with elevation

Troubleshooting

• "Nmap executable was not found"
  • Install Nmap, then close and reopen your terminal
  • Confirm nmap runs from your terminal: nmap -V
• "Permission denied" or missing SYN/OS results
  • Run the terminal as Administrator (Windows) or use sudo (Linux/macOS)
• No output / only warnings
  • Check firewall rules on the target and your network
  • Try different timing options (e.g., -T3 or -T4) via custom scan

Safety and ethics

Only scan systems you own or are explicitly authorized to test. Unauthorized scanning may be illegal or violate terms of service.

File map

• main_v1.7.py – interactive Nmap wrapper with multiple scan profiles
• main_v1.6.py – previous iteration; deprecated in favor of v1.7, kept for reference
• main_v1.1.py – earlier, simpler version (basic SYN/TCP scan)
