+## Configuration Troubleshooting
+
+### Common Configuration Issues
+
+#### ❌ **Field Name Errors**
+
+**Problem**: Service fails to start with `storage path is required` or defaults to `./uploads`
+
+```bash
+# ❌ WRONG - Missing underscore
+[server]
+storagepath = "/opt/hmac-file-server/data/uploads"
+
+# ✅ CORRECT - Use underscores in field names
+[server]
+storage_path = "/opt/hmac-file-server/data/uploads"
+```
+
+**Common Field Name Corrections:**
+- `storagepath` → `storage_path`
+- `listenport` → `listen_address`
+- `bindip` → `bind_ip`
+- `pidfilepath` → `pid_file`
+- `metricsenabled` → `metrics_enabled`
+
+#### ❌ **Path & Permission Issues**
+
+**Problem**: `directory is not writable: permission denied`
+
+```bash
+# Check directory ownership
+ls -la /opt/hmac-file-server/data/
+
+# Fix ownership for systemd service
+sudo chown -R hmac-file-server:hmac-file-server /opt/hmac-file-server/data/
+sudo chmod 750 /opt/hmac-file-server/data/uploads
+```
+
+#### ❌ **Network Resilience Not Working**
+
+**Problem**: Network events not detected, uploads don't resume after network changes
+
+```toml
+# ✅ Enable network events in uploads section
+[uploads]
+networkevents = true  # This enables the feature
+
+# ✅ Add network resilience configuration
+[network_resilience]
+enabled = true
+quality_monitoring = true
+upload_resilience = true
+```
+
+#### ❌ **Service Fails with Read-Only File System**
+
+**Problem**: `open uploads/.write_test: read-only file system`
+
+**Cause**: Conflicting local directories or systemd restrictions
+
+```bash
+# Remove conflicting directories
+sudo rm -rf /opt/hmac-file-server/uploads
+
+# Use absolute paths in configuration
+[server]
+storage_path = "/opt/hmac-file-server/data/uploads"  # Absolute path
+```
+
+### 🛠️ **Quick Diagnostic Commands**
+
+```bash
+# 1. Auto-fix common field naming issues (recommended)
+./fix-config.sh config.toml
+
+# 2. Validate configuration syntax
+./hmac-file-server --validate-config
+
+# 3. Check service logs for errors
+journalctl -u hmac-file-server.service -f
+
+# 4. Test configuration manually
+sudo -u hmac-file-server ./hmac-file-server -config config.toml --validate-config
+
+# 5. Check directory permissions
+ls -la /opt/hmac-file-server/data/
+stat /opt/hmac-file-server/data/uploads
+```
+
+### 📋 **Configuration Checklist**
+
+Before starting the service, verify:
+
+- ✅ All field names use underscores (`storage_path`, not `storagepath`)
+- ✅ Absolute paths for all directories
+- ✅ Correct user ownership (`hmac-file-server:hmac-file-server`)
+- ✅ Proper directory permissions (750 for data directories)
+- ✅ No conflicting local directories in working directory
+- ✅ Network events enabled if using network resilience

-# Configuration Notes:
-# 1. Set networkevents = true in [server] section to enable network monitoring
-# 2. fast_detection = true enables 1-second polling instead of 5-second polling
-# 3. quality_monitoring = true adds RTT and packet loss monitoring
-# 4. predictive_switching = true switches networks proactively before complete failure
-# 5. mobile_optimizations = true uses mobile-friendly thresholds (higher RTT tolerance, etc.)
-# 6. Extended timeouts and retry counts help with mobile network instability
-# 7. Longer session persistence accommodates network switching delays
-
-# Mobile Network Switching Benefits:
-# • WLAN ↔ 5G IPv6 switching: Fast detection (1s) + predictive switching
-# • Dual connectivity (Wired + WiFi): Quality monitoring selects best interface  
-# • Cellular optimization: Higher RTT/packet loss tolerance + more retries
-# • Session mobility: 10-minute recovery window for IP address changes
-# • Proactive switching: Network degradation detected before complete failure

+# HMAC File Server 3.2 Test Suite
+
+This directory contains comprehensive testing tools for the HMAC File Server 3.2 "Tremora del Terra".
+
+## 🚀 Quick Start
+
+Run the complete test suite:
+```bash
+./comprehensive_test_suite.sh
+```
+
+## 📋 Test Coverage
+
+The comprehensive test suite covers:
+
+### ✅ Core Functionality
+- **HMAC Validation**: Ensures proper authentication
+- **File Extensions**: Tests allowed/blocked file types
+- **Upload Mechanics**: Validates upload process
+- **Server Health**: Checks service availability
+
+### 🎥 XMPP Integration
+- **MP4 Upload**: Tests video file sharing for XMPP clients
+- **Image Upload**: Tests image sharing (PNG, JPEG)
+- **File Size Limits**: Validates large file handling
+
+### 🌐 Network Resilience (3.2 Features)
+- **Health Monitoring**: Tests network resilience endpoints
+- **Metrics Collection**: Validates monitoring capabilities
+- **Mobile Switching**: Supports seamless network transitions
+
+### 🚫 Security Testing
+- **Invalid HMAC**: Ensures rejected authentication fails
+- **Unsupported Extensions**: Confirms blocked file types
+- **Path Validation**: Tests file path sanitization
+
+## 🔧 Commands
+
+```bash
+# Run all tests
+./comprehensive_test_suite.sh
+
+# Setup test files only
+./comprehensive_test_suite.sh setup
+
+# Clean up test files
+./comprehensive_test_suite.sh clean
+
+# Show help
+./comprehensive_test_suite.sh help
+```
+
+## 📊 Test Results
+
+Tests generate detailed logs with:
+- ✅ **Pass/Fail status** for each test
+- 🕒 **Timestamps** for performance tracking
+- 📝 **Detailed output** saved to `/tmp/hmac_test_results_*.log`
+- 📈 **Summary statistics** (passed/failed counts)
+
+## 🎯 Expected Results
+
+When all systems are working correctly:
+- **✅ PASS**: HMAC validation
+- **✅ PASS**: MP4 upload (XMPP)
+- **✅ PASS**: Image upload  
+- **✅ PASS**: Large file upload
+- **✅ PASS**: Server health check
+- **❌ FAIL**: Invalid HMAC (should fail)
+- **❌ FAIL**: Unsupported extension (should fail)
+
+## 🔍 Troubleshooting
+
+### Common Issues
+1. **Connection refused**: Check if server is running
+2. **403 Forbidden**: Verify HMAC key configuration
+3. **400 Bad Request**: Check file extension configuration
+4. **Timeout**: Large files may need adjusted timeouts
+
+### Debug Mode
+For detailed debugging, check server logs:
+```bash
+sudo journalctl -u hmac-file-server -f
+```
+
+## 📁 File Cleanup
+
+The test suite automatically cleans up temporary files, but if needed:
+```bash
+rm -f /tmp/test_*.{txt,mp4,bin,png,xyz}
+rm -f /tmp/hmac_test_results_*.log
+```
+
+## 🔧 Configuration
+
+Tests use these defaults (modify in script if needed):
+- **Base URL**: `https://xmpp.uuxo.net`
+- **Test User**: `c184288b79f8b7a6f7d87ac7f1fb1ce6dcf49a80`
+- **HMAC Key**: Configured in script
+
+## 📝 Legacy Test Files
+
+This comprehensive suite replaces these scattered root-level test files:
+- `test-hmac-fixed.sh` → Integrated into comprehensive suite
+- `test-upload.sh` → Covered by upload tests
+- `debug-uploads.sh` → Debug logging integrated
+- `comprehensive_upload_test.sh` → Replaced by this suite
+- Various monitor scripts → Health checks integrated
+
+## 🎉 3.2 "Tremora del Terra" Features Tested
+
+- ✅ **Enhanced Network Resilience**: 1-second detection
+- ✅ **Mobile Network Switching**: WLAN ↔ IPv6 5G seamless transitions
+- ✅ **XMPP File Sharing**: Conversations/Gajim compatibility
+- ✅ **Configuration Validation**: Proper extension loading
+- ✅ **Production Deployment**: SystemD, Docker, Podman support
