🛡️ ActiveVPN

The Ultimate Network Privacy & VPN Detection Tool

ActiveVPN inspects your system's network interfaces, analyzes running processes, checks your external IP against known hosting providers, and performs DNS leak tests — all in one hacker-style terminal UI. It tells you whether your VPN is actually working.

Key Features

• Deep scan — detects VPNs via interface names, process names, and IP reputation in one pass.
• Tor detection — specifically checks for active Tor services.
• External IP analysis — queries public IP APIs and flags datacenter/hosting/proxy IPs.
• DNS leak detection — compares your traffic IP with your DNS resolver IP.
• IPv6 leak check — reports your external IPv6 address and warns when IPv6 may leak around a tunnel.
• Overall verdict — combines every signal into a confidence score and a CLEAN / SUSPICIOUS / LIKELY VPN-PROXY / VPN DETECTED label.
• Kill switch — terminates active VPN processes, with a --kill-force fallback.
• History & export — automatically logs scans to your platform's data directory, viewable with --history and exportable as JSON, CSV, or TXT.
• Library API — importable as a Python package (activevpn.scan(), NetworkDetector, typed ScanResult), with silent mode and watch callbacks for developers.
• Watch mode — continuously re-scans at a configurable interval.
• Configurable — patterns, colors, and API endpoints can be overridden with a JSON config file.

Installation

Requires Python 3.8 or newer and pip.

pip install activevpn

Or install from source:

git clone https://github.com/rkriad585/ActiveVPN.git
cd ActiveVPN
pip install -r requirements.txt

See docs/installation.md for platform-specific notes (Linux, macOS, Windows, Termux).

Quick Start

# Run a full scan
activevpn

You should see a system check, an external IP analysis, a DNS consistency check, and an overall verdict.

Usage Examples

# Standard network scan (interfaces, processes, IP, DNS)
activevpn

# Kill active VPN processes (requires admin/root)
sudo activevpn --kill

# Force-kill stubborn VPN processes
sudo activevpn --kill-force

# Show past scan results
activevpn --history

# Export scan history as CSV
activevpn --export csv

# Clear all saved history
activevpn --clear-history

# Continuously rescan every 30 seconds
activevpn --watch 30

# Verbose debug logging
activevpn --debug

# Show help
activevpn --help

Exit codes: 0 = no VPN detected, 1 = VPN/Tor/Proxy detected, 2 = offline or error. Full reference in docs/cli.md.

Documentation

Interface

ActiveVPN is a command-line tool. It is distributed as the activevpn console script (see [project.scripts] in pyproject.toml) and can also be launched with python main.py.

When run without flags it performs a full scan and prints four sections:

1. System Internal Check — detected VPN/Tor interfaces and processes.
2. External IP Analysis — public IP, country, ISP/org, IPv4/IPv6, and a verdict.
3. DNS Consistency Check — traffic IP vs. DNS resolver IP.
4. Overall Verdict — confidence score (0–100) and label.

The tool returns meaningful exit codes (0/1/2) so it can be used in scripts and CI.

The flow: main.run() parses arguments → NetworkDetector.scan_network() collects system + online signals → _compute_verdict() scores them → save_log() persists the result → tables/panels are rendered with rich.

Using as a Library

import activevpn

# One-shot scan (silent — no TUI)
result = activevpn.scan(console=None)
print(result.verdict.label, result.verdict.score)   # CLEAN 0
print(result.to_json())                             # serializable output

# Programmatic configuration (stored under ~/.config/neostore/ActiveVPN/config.toml)
cfg = activevpn.load_config()
cfg.vpn_process_names.append("my-vpn-daemon")

# Continuous watch with callbacks
detector = activevpn.NetworkDetector(console=None, config=cfg)
for r in detector.watch(interval=60, on_change=lambda r: print("Verdict changed!", r.verdict.label)):
    pass

See docs/architecture.md for details.

Requirements

No special hardware is required. --kill and --kill-force need administrator/root privileges.

Prerequisites

• Python 3.8+ — download from python.org or your package manager.
• pip — bundled with Python on modern installers.

On Linux:

sudo apt update && sudo apt install -y python3 python3-pip

On macOS (Homebrew):

brew install python

Development

# Clone and install dependencies
git clone https://github.com/rkriad585/ActiveVPN.git
cd ActiveVPN
python -m venv .venv
. .venv/bin/activate        # Windows: .venv\Scripts\Activate.ps1
pip install -r requirements.txt pytest build twine

# Run the test suite
pytest -q

# Build the distributable packages
python -m build

# Verify the built artifacts
python -m twine check dist/*

The CI workflow (.github/workflows/ci.yml) runs pytest on Ubuntu, Windows, and macOS with Python 3.8 and 3.12. See docs/development.md.
