In environments where IP addresses change regularly, maintaining accurate access control becomes challenging. This bundle solves that problem by automatically synchronizing your Apache configuration with the current IP addresses of your dynamic DNS domains. Understanding Dynamic DNS and Access Control -------------------------------------------- [](#understanding-dynamic-dns-and-access-control) Dynamic DNS (DDNS) is a method of automatically updating DNS records in real-time. It's commonly used when your IP address might change periodically, such as with residential internet connections or cloud services that don't provide static IPs. While DDNS ensures your domain always points to the correct IP, maintaining access control based on these IPs requires additional automation. This bundle bridges that gap by monitoring your dynamic DNS domains and automatically updating your Apache configuration whenever IP changes are detected. It supports both IPv4 and IPv6, providing comprehensive coverage for modern network environments. Core Features ------------- [](#core-features) The bundle has been designed with reliability and efficiency in mind: Monitoring and Updates: - Tracks multiple dynamic DNS domains simultaneously - Supports both IPv4 and IPv6 address resolution - Implements intelligent caching to minimize unnecessary DNS queries - Provides automatic updates when IP changes are detected Safety and Reliability: - Creates automatic backups before any modifications - Implements automatic rollback on failure - Provides comprehensive logging for all operations - Maintains atomic operations to prevent configuration corruption Integration: - Seamlessly integrates with Symfony's ecosystem - Works with Apache's .htaccess configuration - Supports both manual and automated operation - Provides command-line interface for easy management System Requirements ------------------- [](#system-requirements) Before installation, ensure your environment meets these prerequisites: - PHP 8.1 or higher Required for modern language features and type safety - Symfony 6.0 or 7.0 Provides the foundation for robust application architecture - Apache web server with .htaccess support Necessary for implementing dynamic access control - Write permissions for the .htaccess file Required for automated configuration updates - DNS resolution capabilities Needed for resolving dynamic DNS entries Installation and Setup ---------------------- [](#installation-and-setup) 1. First, install the package using Composer: ``` composer require monosize/dynamic-dns-ip-updater ``` 2. Register the bundle in your Symfony application. Add this line to `config/bundles.php`: ``` return [ // ... other bundles ... Monosize\DynamicDnsIpUpdater\DynamicDnsIpUpdaterBundle::class => ['all' => true], ]; ``` 3. Configure your dynamic DNS domains by creating or updating your `.env` file: ``` # List your domains, separated by commas # Example: DNS_DOMAINS=office.dynamicdns.net,backup.dyndns.org DNS_DOMAINS=yourdomain1.example.org,yourdomain2.example.org ``` Configuration Management ------------------------ [](#configuration-management) The bundle manages a dedicated section in your .htaccess file, marked with clear delimiters: ``` # START DYNAMIC DNS BLOCK # Dynamic DNS IPv4 addresses Require ip 203.0.113.1 # Dynamic DNS IPv6 addresses Require ip 2001:db8::1 # END DYNAMIC DNS BLOCK ``` This block is automatically maintained by the bundle. The clear delimiters ensure: - Easy identification of managed sections - Safe updates without affecting other configurations - Clean integration with existing access controls Operation Modes --------------- [](#operation-modes) The bundle can operate in two primary modes: ### Manual Operation [](#manual-operation) Use the command-line interface for direct control: ``` # Standard update - checks cache and updates only if needed php bin/console dns:update-dynamic-ip # Force update - bypasses cache and forces configuration refresh php bin/console dns:update-dynamic-ip --force ``` ### Automated Operation [](#automated-operation) For continuous monitoring, you can implement automatic updates using either Symfony's Scheduler or traditional cron jobs. Using Symfony Scheduler (Recommended): ``` # config/packages/scheduler.yaml scheduler: dns_update: type: cron schedule: '*/5 * * * *' # Updates every 5 minutes command: 'dns:update-dynamic-ip' ``` Using Traditional Crontab: ``` # Updates every 5 minutes */5 * * * * /usr/bin/php /path/to/your/project/bin/console dns:update-dynamic-ip ``` Understanding the Update Process -------------------------------- [](#understanding-the-update-process) Each update cycle follows a carefully designed process to ensure reliability: 1. Domain Resolution: - Reads configured domains from environment - Resolves current IPv4 and IPv6 addresses - Validates resolution results 2. Change Detection: - Compares new IPs with cached values - Determines if updates are necessary - Optimizes performance by avoiding unnecessary writes 3. Safe Updates: - Creates timestamped backup of current configuration - Validates backup creation - Implements update using atomic operations 4. Error Handling: - Detects any problems during update - Automatically restores from backup if needed - Logs detailed error information 5. Cache Management: - Updates cache with new IP addresses - Sets appropriate cache expiration - Maintains cache consistency Monitoring and Logging ---------------------- [](#monitoring-and-logging) The bundle integrates with Symfony's logging system to provide comprehensive operational insights: Configuration Changes: - IP address updates - Backup operations - Configuration modifications Error Conditions: - DNS resolution failures - File operation issues - Permission problems Performance Metrics: - Cache hits and misses - Update timing - Resource usage Logs are written to your Symfony application's log directory (`var/log/`), following the standard Symfony logging conventions. Development and Testing ----------------------- [](#development-and-testing) The bundle includes a comprehensive test suite and development tools: Running Tests: ``` # Complete test suite with all checks composer check-all # Individual components composer test # Unit tests composer test-coverage # Coverage analysis composer cs-check # Code style validation composer cs-fix # Automatic style fixes composer phpstan # Static analysis ``` Test Coverage Analysis: To generate detailed coverage reports, install either PCOV (recommended) or Xdebug: ``` # Using PCOV pecl install pcov # Or using Xdebug pecl install xdebug ``` Contributing ------------ [](#contributing) We welcome contributions that improve the bundle's functionality or documentation.
