General Questions

What is the Tor VPN System?

The Tor VPN System is a comprehensive management tool for the Tor network that provides both graphical (GUI) and command-line (CLI) interfaces for configuring, managing, and routing traffic through Tor. It supports country-specific exit node selection, transparent proxy configuration, and includes diagnostic tools.

What are the system requirements?

  • Operating System: Linux (Ubuntu 20.04+, Debian 11+), macOS 10.15+, Windows 10+
  • Python: 3.10 or higher
  • RAM: 2 GB minimum, 4 GB recommended
  • Disk Space: 500 MB for installation, 1 GB for logs and data
  • Network: Stable internet connection

See Installation for detailed requirements.

Is this system free to use?

Yes, the Tor VPN System is released under the MIT License and is free to use, modify, and distribute. See the LICENSE file for details.

Is Tor VPN System affiliated with the Tor Project?

No, this is an independent project that uses the Tor network. It is not officially affiliated with the Tor Project, though it uses Tor's official software and follows Tor's guidelines.

Can I use this for illegal activities?

No. This software is provided for legitimate purposes such as privacy protection, circumventing censorship, and security research. Misuse of this software for illegal activities is strictly prohibited and may violate local laws.

Installation Questions

How do I install the Tor VPN System?

See the detailed Installation Guide for step-by-step instructions for Linux, macOS, and Windows.

Do I need to install Tor separately?

Yes, Tor must be installed separately. The installation guide provides instructions for installing Tor on each platform.

Can I use a virtual environment?

Yes, using a virtual environment is recommended:

python -m venv .venv
source .venv/bin/activate  # Linux/macOS
.venv\Scripts\activate  # Windows

What Python version do I need?

Python 3.10 or higher is required. Python 3.11+ is recommended for better performance and security.

Can I install this on multiple systems?

Yes, you can install and use the system on multiple systems. Each installation will have its own configuration.

Configuration Questions

Where are configuration files stored?

Default locations:

  • Linux: ~/.tor_config/torrc or ~/.tor/torrc
  • macOS: ~/Library/Application Support/Tor/torrc
  • Windows: %APPDATA%\tor\torrc

See Configuration for more details.

How do I change the Tor control password?

Run the configuration script:

python tor_custom_config.py

It will prompt for a new password and update the configuration.

Can I use a custom torrc file?

Yes, you can specify a custom torrc path:

python tor_auto_torrc_config.py /custom/data/dir /custom/log/dir /custom/torrc/path

How do I select a specific country for the exit node?

In the GUI, click "Connect" and enter the two-letter country code (e.g., "us", "de", "gb").

Via command line:

from tor_vpn_beta import connect_to_tor
connect_to_tor("us")

What countries are supported?

The system supports exit nodes in 200+ countries. See the SERVERS dictionary in tor_vpn_beta.py for the complete list.

Can I use multiple exit nodes?

You can specify multiple countries in torrc:

ExitNodes {us},{de},{gb}

However, Tor will select one at random from the specified set.

Usage Questions

How do I start the GUI application?

python tor_vpn_beta.py

Can I use this without the GUI?

Yes, all functionality is available via command-line tools:

  • tor_network_test.py - Test connection
  • tor_diagnostic_repair.py - Diagnostics
  • tor_custom_config.py - Configuration
  • tor_auto_torrc_config.py - Automated setup

How do I route all system traffic through Tor?

Use the transparent proxy setup:

sudo python tor_route_traffic_setup.py

⚠️ Warning: This routes ALL traffic through Tor. Use with caution.

How do I configure my browser to use Tor?

Firefox:

  1. Open Settings > Network Settings
  2. Manual proxy configuration
  3. SOCKS Host: 127.0.0.1, Port: 9050
  4. SOCKS v5
  5. Check "Proxy DNS when using SOCKS v5"

Chrome:

google-chrome --proxy-server="socks5://127.0.0.1:9050"

How do I test if Tor is working?

Run the network test:

python tor_network_test.py

Or use curl:

curl --socks5 127.0.0.1:9050 https://check.torproject.org

Can I use this with applications other than browsers?

Yes, configure the application to use SOCKS5 proxy at 127.0.0.1:9050, or set environment variables:

export http_proxy="socks5h://127.0.0.1:9050"
export https_proxy="socks5h://127.0.0.1:9050"

How do I change my exit node?

Disconnect and reconnect with a different country code, or use the Stem API:

from stem.control import Controller
from stem import Signal

with Controller.from_port(port=9051) as controller:
    controller.authenticate(password="your_password")
    controller.set_conf("ExitNodes", "{de}")
    controller.signal(Signal.NEWNYM)

Security Questions

Is this system secure?

The system has security considerations that need to be addressed. See the Security Guide for detailed information on current security issues and best practices.

What are the main security concerns?

Current concerns include:

  • Hardcoded passwords in some scripts
  • Limited input validation
  • Password handling in some scripts
  • Logging of potentially sensitive information

See Security Guide for details and mitigation strategies.

How do I secure my installation?

  1. Change default passwords
  2. Set proper file permissions (600 for torrc)
  3. Use environment variables for sensitive data
  4. Restrict log file access
  5. Keep dependencies updated
  6. Configure firewall rules

See Security Guide for comprehensive security recommendations.

Should I run Tor as root?

No, Tor should not be run as root. The system includes warnings about this. Run Tor as a dedicated user (typically debian-tor on Linux).

Are my passwords stored securely?

Currently, passwords are stored as hashes in torrc files. However, the system has hardcoded passwords in some scripts that should be removed before production use. See Security Guide for details.

Can I use this on a public network?

Yes, Tor is designed to provide privacy even on public networks. However, ensure your local system is secure and follow best practices.

Troubleshooting Questions

Tor won't start. What should I do?

  1. Check if Tor is installed: tor --version
  2. Check service status: sudo systemctl status tor
  3. Check logs: sudo journalctl -xe | grep -i tor
  4. Validate configuration: tor --verify-config
  5. See Troubleshooting for more details.

I get "Control port not accessible" error. How do I fix it?

  1. Verify Tor is running: ps aux | grep tor
  2. Check if port is listening: netstat -tulnp | grep 9051
  3. Check firewall settings
  4. Verify torrc has ControlPort set
  5. See Troubleshooting for more details.

Authentication is failing. What should I check?

  1. Verify password hash in torrc
  2. Try regenerating password: python tor_custom_config.py
  3. Check authentication method (password vs cookie)
  4. Verify cookie file exists and has correct permissions
  5. See Troubleshooting for more details.

The GUI won't open. What should I do?

  1. Install tkinter: sudo apt install python3-tk
  2. Check display environment: echo $DISPLAY
  3. Try running with explicit display: export DISPLAY=:0
  4. See Troubleshooting for more details.

Connection is very slow. How can I improve it?

  1. Try different exit nodes (geographically closer)
  2. Check your internet connection
  3. Monitor exit node performance
  4. Reduce circuit rebuild frequency
  5. See Performance Considerations for more tips.

I'm getting permission errors. What should I do?

  1. Run with sudo if required: sudo python <script>
  2. Check file permissions: ls -la ~/.tor_config/torrc
  3. Fix permissions: chmod 600 ~/.tor_config/torrc
  4. Fix ownership: chown $USER:$USER ~/.tor_config/torrc
  5. See Troubleshooting for more details.
