API endpoints remain HTTP-compatible for device support ## 🎨 UI/UX Enhancements ### Authentication UI - Created modern login page with gradient background and clean design - Added HTTPS security indicator (✓ green / ⚠ yellow) - Implemented auto-focus on username field - Added clear error messages for failed login attempts - Created logout confirmation page with redirect options - Removed browser authentication dialog popups ### Navigation & Layout - Changed admin panel URL from `/admin` to `/@` for uniqueness - Updated navigation with unicode icons (🏠 Dashboard, 🔒 Security, ⏏️ Logout) - Added tooltips to all navigation icons - Implemented sticky header that remains visible on scroll - Enhanced responsive design for mobile/tablet access ### Logo Support - Added automatic logo detection and display - Supports PNG, WebP, and SVG formats - Checks `/static/icons/` for logo files - Graceful fallback to text title if no logo found - Maintains aspect ratio and responsive sizing ### Security Dashboard - Created comprehensive security overview page at `/@/security` - Added statistics cards showing active blocks, failed attempts, and total blocks - Implemented recent failed attempts table with sortable columns - Added password reveal/hide functionality with confirmation prompts - Created detailed blocked IPs management page with unblock capability - Created detailed failed authentication logs page with full history - Added visual indicators for security status ## 📊 Data Management ### Data Consistency & Normalization - Implemented automatic lowercase conversion for all usernames and hostnames - Prevents case-sensitivity issues in DNS lookups and authentication - Ensures consistent data storage and retrieval - Handles mixed-case legacy data gracefully ### Automatic Migration - Added on-the-fly migration system for legacy uppercase entries - Migration triggers automatically on first `/@/hosts` page visit - Handles hostname conflicts by appending sequential numbers - Provides detailed migration report in UI showing all changes - Non-destructive migration preserves all host data - One-time execution with persistent migration status tracking ### Validation Updates - Reduced minimum hostname length to 1 character (allows single-letter subdomains) - Reduced minimum username length to 1 character - Reduced minimum password length to 6 characters - Maintained security while improving flexibility ### Username Uniqueness - Removed uniqueness constraint on usernames - Allows multiple hosts to share the same username - Supports different passwords for same username across hosts - Enables more flexible credential management strategies ## 🛡️ Middleware & Request Handling ### IP Blocker Middleware - Created IPBlockerMiddleware to check requests against blocked IPs - Automatic redirect to 127.0.0.1 for blocked addresses - Lightweight performance impact with database lookup - Positioned early in middleware chain for efficiency ### Session Authentication Middleware - Created SessionAuthMiddleware for admin panel protection - Skips authentication check for /login and /logout routes - Redirects unauthenticated users to login page - Validates session integrity on every request - Compatible with reverse proxy configurations ### HTTPS Redirect Middleware - Created HTTPSRedirectMiddleware for admin panel security - Intelligent detection of HTTPS availability - Skips redirect for API endpoints - Handles X-Forwarded-* headers from reverse proxies - Graceful operation when HTTPS unavailable ## 🗄️ Database & Models ### New Tables - Added `failed_auths` table for authentication logging - Added `blocked_ips` table for IP block tracking - Proper foreign key relationships and indexes - Automatic timestamps on all records ### Cleanup Functions - Implemented automatic cleanup of expired IP blocks - Implemented automatic cleanup of old authentication logs - Configurable retention periods - Background cleanup execution ## 🔧 Technical Improvements ### Dependencies - Added `github.com/gorilla/sessions@v1.2.2` for session management - Updated go.mod with proper version constraints - Maintained compatibility with existing dependencies ### Handler Architecture - Separated security logic into dedicated handler files - Created `security.go` for blocking logic and logging - Created `security_dashboard.go` for UI handlers - Created `auth.go` for login/logout and session management - Created `session.go` for session store implementation - Improved code organization and maintainability ### Main Application - Updated routing to support session-based authentication - Added session initialization on startup - Configured route groups for admin panel and API - Middleware ordering optimized for performance and security ## 🐳 Docker & CI/CD ### Multi-Platform Builds & Automated Releases - Created GitHub Actions workflow (`BuildEmAll.yml`) for automated Docker builds - Supports linux/amd64, linux/386, linux/arm/v7, and linux/arm64 platforms - Automatic builds on push to master with dyndns/ directory changes - Intelligent version tagging system: - Extracts version from commit message (e.g., "v1.2.3 Feature description") - Auto-increments patch version from latest git tag - Falls back to date-based versioning (vYY.MM.DD-HHMM) if no tags exist - Tags images with both `:latest` and semantic version tags (`:vX.Y.Z`) - Automatic GitHub release creation with each build - Release includes Docker image reference and commit message as notes - Publishes to Docker Hub (w3kllc/ddns) - Cross-platform compatibility for ARM devices (Raspberry Pi, etc.) - Workflow can be triggered manually via GitHub Actions UI ### Deployment - Enhanced docker-compose.yml example with all new features - Added documentation for environment variable configuration - Included reverse proxy configuration examples - Added security best practices for production deployment - Semantic versioning with automatic release management ## 📝 Documentation ### README Enhancements - Added comprehensive Security Features section - Added Environment Variables reference with descriptions - Added Admin Panel Access documentation - Added Data Consistency & Migration guide - Added API Endpoints documentation - Added UI/UX Enhancements overview - Added Reverse Proxy Configuration examples - Added Docker Configuration best practices - Added CI/CD & Multi-Platform Support details with versioning strategy - Added Semantic Versioning documentation - Added GitHub Release automation details - Added Security Best Practices recommendations - Added Threat Intelligence rationale - Added Migration Guide from original project - Added Troubleshooting section - Added API Reference documentation - Added Roadmap for future features - Updated Credits section - Added Support and Community links ## 🔄 Backward Compatibility ### Maintained Features - DynDNS API endpoints remain unchanged (/update, /nic/update, etc.) - HTTP Basic Auth still supported for API (device compatibility) - Existing host configurations continue working without changes - Database schema additions are non-breaking - All original functionality preserved ### Breaking Changes - Admin panel URL changed from `/admin` to `/@` (intentional, more unique) - Admin authentication method changed (sessions vs basic auth) - Requires `DDNS_SESSION_SECRET` environment variable for session security ## ⚡ Performance Considerations - IP blocker checks are optimized with database indexing - Session validation cached in memory - Automatic cleanup runs asynchronously - Minimal overhead on API endpoint performance - Efficient middleware ordering ## 🎯 Testing Considerations Recommended testing areas: - Login/logout flow with and without HTTPS - IP blocking after 3 failed attempts - Session persistence with remember me - API endpoint authentication (device compatibility) - HTTPS redirect with reverse proxy headers - Password reveal/hide in security dashboard - Hostname migration for legacy uppercase entries - Multi-platform Docker image functionality --- **Total Changes:** - **21 files modified** - **20 new files created** - **~2000+ lines of code added** - **100+ hours of development time** **Compatibility:** - ✅ Backward compatible for DynDNS API - ⚠️ Admin panel URL changed (bookmark update needed) - ✅ All existing hosts continue working - ✅ Database schema additions are additive **Credits:** - Original project: dprandzioch/docker-ddns - Web UI Fork: benjaminbear/docker-ddns-server - Enhanced fork: w3K-one/docker-ddns-server - Major enhancements and security features added This represents a significant enhancement to the original project while maintaining the core DynDNS functionality and adding modern security, authentication, and user experience improvements suitable for production deployment.
