Implement Cross-Platform VPN Configuration Detection and Parsing

Description

Task

Write functions to extract and parse VPN configuration information from system commands

Acceptance Criteria

• Supports VPN configuration detection on macOS and Linux
• Provides detailed VPN configuration information
• Handles command execution errors gracefully
• Returns a consistent configuration dictionary across platforms
• Logs diagnostic information for troubleshooting
• Minimal false positives in VPN detection
• Performance overhead is negligible

Summary of Work

This pull request introduces a comprehensive VPN configuration parsing system that supports multiple platforms (macOS and Linux) with robust error handling and modular design.

Key Implementation Details:

• Created VPNConfigParser class with static and class methods
• Implemented platform-specific VPN detection for macOS and Linux
• Used subprocess for system command execution
• Added comprehensive logging and error handling
• Supports detection of VPN services, interfaces, and active connections

Parsing Strategies:

1. macOS Detection:

   • Uses networksetup to list network services
   • Utilizes scutil to check active VPN connections
   • Extracts VPN service names and connection status

2. Linux Detection:

   • Uses 'ip tuntap' to identify VPN interfaces
   • Checks routing table for active VPN connections
   • Handles different network configurations

Resilience and Error Handling:

• Graceful fallback for unsupported platforms
• Comprehensive exception handling
• Default empty configuration if detection fails
• Detailed logging for troubleshooting

Future Extensibility:

• Modular design allows easy addition of new platforms
• Flexible configuration dictionary for future enhancements

Changes Made

• Created VPNConfigParser class in src/vpn_config_parser.py
• Implemented run_command method for system command execution
• Added parse_macos_vpn_config method for macOS VPN detection
• Added parse_linux_vpn_config method for Linux VPN detection
• Created detect_vpn_config method for cross-platform support
• Implemented comprehensive error handling and logging

Tests

• Test successful command execution
• Test command execution failure handling
• Test macOS VPN configuration parsing (platform-specific)
• Test Linux VPN configuration parsing (platform-specific)
• Test cross-platform VPN configuration detection
