## Troubleshooting
### Build Issues
#### Missing Dependencies
```bash
# Clean module cache and re-download
go clean -modcache
go mod download
```
#### Go Version Issues
```bash
# Check Go version
go version
# Update Go if needed (Ubuntu/Debian)
sudo snap install go --classic
# Or download from https://golang.org/dl/
```
#### Network Resilience Files Missing
```bash
# Check if files exist
ls -la cmd/server/upload_session.go
ls -la cmd/server/network_resilience.go
ls -la cmd/server/chunked_upload_handler.go
ls -la cmd/server/integration.go
# If missing, the build will work but without network resilience features
# Core functionality remains unchanged
```
### Runtime Issues
#### Port Already in Use
```bash
# Check what's using port 8080
sudo netstat -tlnp | grep :8080
# Kill process if needed
sudo kill $(sudo lsof -t -i:8080)
```
#### Permission Issues
```bash
# Make binary executable
chmod +x hmac-file-server
# For system service installation
sudo chown root:root hmac-file-server
sudo chmod 755 hmac-file-server
```
#### Config File Issues
```bash
# Validate config syntax
./hmac-file-server --config config.toml --validate
# Use example config as starting point
cp config-example-xmpp.toml config.toml
```
## Build Performance
### Faster Builds
```bash
# Use build cache
export GOCACHE=$(go env GOCACHE)
# Parallel builds
go build -p 4 cmd/server/*.go
# Skip tests during development
go build -a cmd/server/*.go
```
### Smaller Binaries
```bash
# Strip debug info and symbol table
go build -ldflags="-s -w" cmd/server/*.go
# Use UPX compression (if installed)
upx --best hmac-file-server
```
## Deployment
### System Service
```bash
# Copy binary to system location
sudo cp hmac-file-server /usr/local/bin/
# Create systemd service
sudo cp hmac-file-server.service /etc/systemd/system/
sudo systemctl enable hmac-file-server
sudo systemctl start hmac-file-server
```
### Reverse Proxy Setup
```bash
# Nginx configuration
sudo cp nginx-hmac-file-server.conf /etc/nginx/sites-available/
sudo ln -s /etc/nginx/sites-available/hmac-file-server.conf /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx
```
This build process ensures that:
- ✅ **Backward Compatibility**: Works with or without network resilience files
- ✅ **Feature Detection**: Automatically includes available network resilience features
- ✅ **Zero Downtime**: Existing deployments continue working unchanged
- ✅ **Mobile Optimized**: New features specifically address network switching issues

# HMAC File Server 3.2 Ultimate Fixed - Release Notes
## 🚀 Major Release: Complete Configuration Modernization & Enhanced Multi-Platform Support
**Release Date:** July 18, 2025
**Version:** 3.2 Ultimate Fixed
**Codename:** "Architecture Revolution"
---
## 🎯 What's New in 3.2 Ultimate Fixed
This release represents a **complete modernization** of HMAC File Server with comprehensive configuration updates, enhanced multi-architecture support, and improved project organization. Every aspect of the server has been refined for better performance, reliability, and ease of deployment.
### 🔧 Configuration System Overhaul
#### **Modernized Field Names**
All configuration fields have been updated to use consistent, modern naming conventions:
| **Old Field Name** | **New Field Name** | **Purpose** |
|-------------------|-------------------|-------------|
| `listenport` | `listen_address` | Server binding address and port |
| `storagepath` | `storage_path` | File storage directory |
| `metricsenabled` | `metrics_enabled` | Prometheus metrics toggle |
| `readtimeout` | `read_timeout` | HTTP read timeout |
| `writetimeout` | `write_timeout` | HTTP write timeout |
| `idletimeout` | `idle_timeout` | HTTP idle timeout |
#### **Extended Timeout Support**
- **4800-second timeouts** for large file handling (up from 30s)
- Perfect for multi-gigabyte file transfers
- Eliminates timeout errors during long uploads/downloads
- Configurable per operation type
#### **Enhanced Deduplication System**
```toml
[deduplication]
enabled = true
directory = "./deduplication"
maxsize = "1GB" # Files larger than 1GB bypass deduplication for performance
```
#### **Dynamic Worker Scaling**
```toml
[server]
enable_dynamic_workers = true
worker_scale_up_thresh = 50 # Scale up when queue exceeds 50
worker_scale_down_thresh = 10 # Scale down when queue drops below 10
```
### 🏗️ Multi-Architecture Build System
#### **New Build Script Features**
The `buildgo.sh` script now supports:
- **Interactive Architecture Selection Menu**
- **Cross-compilation Support** for:
- **AMD64** (x86_64) - Standard servers and desktops
- **ARM64** (AArch64) - Modern ARM processors, Raspberry Pi 4+
- **ARM32v7** - Older ARM devices, Raspberry Pi 3 and earlier
- **Build-All Option** - Creates all architectures in one command
- **Smart Binary Naming** - `hmac-file-server_amd64`, `hmac-file-server_arm64`, etc.
- **Color-coded Output** for better user experience
#### **Usage Examples**
```bash
# Interactive mode with menu
./buildgo.sh
# Menu options:
# 1) AMD64 (x86_64)

## 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

## Running with Podman
Podman is a daemonless container engine that's often preferred in enterprise environments for enhanced security and rootless capabilities. HMAC File Server 3.2 provides complete Podman support with optimized deployment scripts.
### Why Choose Podman?
| Feature | Docker | Podman |
|---------|--------|--------|
| **Daemon** | Requires Docker daemon | Daemonless architecture |
| **Root Access** | Requires root for Docker daemon | Can run completely rootless |
| **Security** | Good, but daemon runs as root | Enhanced security, no privileged daemon |
| **Systemd Integration** | Via Docker service | Native systemd integration |
| **Pod Support** | Requires docker-compose or swarm | Native Kubernetes-style pods |
| **Enterprise Use** | Popular in startups/mid-size | Preferred in enterprise environments |
| **SELinux** | Basic support | Excellent SELinux integration |
### Quick Start with Podman
```bash
# Clone repository
git clone https://github.com/PlusOne/hmac-file-server.git
cd hmac-file-server/dockerenv/podman
# One-command deployment
./deploy-podman.sh
# Check status
./deploy-podman.sh status
# View logs
./deploy-podman.sh logs
```
### Manual Directory & Permission Setup
#### **Understanding Container Security Model**
- **Container User**: `appuser` (UID: 1011, GID: 1011)
- **Security Principle**: Never run containers as root (UID 0)
- **Compatibility**: Works across different container runtimes and deployment modes
#### **Step-by-Step Manual Setup**
**Step 1: Create Directory Structure**
```bash
# Create organized directory layout
export HMAC_BASE="/opt/podman/hmac-file-server"
sudo mkdir -p ${HMAC_BASE}/{config,data,deduplication,logs}
# Create subdirectories for uploads and duplicates
sudo mkdir -p ${HMAC_BASE}/data/{uploads,temp}
sudo mkdir -p ${HMAC_BASE}/deduplication/store
sudo mkdir -p ${HMAC_BASE}/logs/{access,error,debug}
```
**Step 2: Set Ownership (CRITICAL)**
```bash
# For Podman Rootless (recommended)
podman unshare chown -R 1011:1011 ${HMAC_BASE}
# For Podman Rootful or Docker
sudo chown -R 1011:1011 ${HMAC_BASE}
# Alternative: Use numeric IDs to avoid user lookup issues
sudo chown -R 1011:1011 ${HMAC_BASE}
```
**Step 3: Set Permissions**
```bash
# Directory permissions (executable for traversal)
sudo chmod 755 ${HMAC_BASE}
sudo chmod 755 ${HMAC_BASE}/{config,data,deduplication,logs}
sudo chmod 755 ${HMAC_BASE}/data/{uploads,temp}
sudo chmod 755 ${HMAC_BASE}/deduplication/store
sudo chmod 755 ${HMAC_BASE}/logs/{access,error,debug}
# Configuration file (read-only)
sudo chmod 644 ${HMAC_BASE}/config/config.toml
```
**Step 4: Verify Ownership**
```bash
# Check ownership recursively
ls -laR ${HMAC_BASE}
# Expected output format:
# drwxr-xr-x 2 1011 1011 4096 Dec 20 10:30 data
# drwxr-xr-x 2 1011 1011 4096 Dec 20 10:30 deduplication
# drwxr-xr-x 2 1011 1011 4096 Dec 20 10:30 logs
# -rw-r--r-- 1 1011 1011 1234 Dec 20 10:30 config/config.toml
```
#### **Container Volume Mapping**
| Host Path | Container Mount | Access Mode | SELinux Label | Purpose |
|-----------|-----------------|-------------|---------------|---------|
| `${HMAC_BASE}/config/config.toml` | `/app/config.toml` | `ro` | `:Z` | Configuration file |
| `${HMAC_BASE}/data/` | `/data/` | `rw` | `:Z` | File uploads |
| `${HMAC_BASE}/deduplication/` | `/deduplication/` | `rw` | `:Z` | Dedup cache |
| `${HMAC_BASE}/logs/` | `/logs/` | `rw` | `:Z` | Application logs |
#### **Complete Manual Run Command**
```bash
# Build container image
podman build -t localhost/hmac-file-server:latest -f dockerenv/podman/Dockerfile.podman .
# Run with proper volume mounts and SELinux labels
podman run -d --name hmac-file-server \
--security-opt no-new-privileges \
--cap-drop=ALL \
--read-only \
--tmpfs /tmp:rw,noexec,nosuid,size=100m \
-p 8888:8888 \
-p 9090:9090 \
-v ${HMAC_BASE}/config/config.toml:/app/config.toml:ro,Z \
-v ${HMAC_BASE}/data:/data:rw,Z \
-v ${HMAC_BASE}/deduplication:/deduplication:rw,Z \
-v ${HMAC_BASE}/logs:/logs:rw,Z \
localhost/hmac-file-server:latest -config /app/config.toml
```
### Troubleshooting Path & Permission Issues
#### **Common Error: Permission Denied**
```bash
# Error in logs
{"level":"error","msg":"failed to create directories: mkdir /data: permission denied"}
```
**Root Cause**: Incorrect ownership or missing directories
**Solution**:
```bash
# Check current ownership
ls -la ${HMAC_BASE}
# Fix ownership (adjust command based on your setup)
# For rootless Podman:
podman unshare chown -R 1011:1011 ${HMAC_BASE}
# For rootful Podman/Docker:
sudo chown -R 1011:1011 ${HMAC_BASE}
# Verify fix
sudo -u "#1011" touch ${HMAC_BASE}/data/test-write
rm ${HMAC_BASE}/data/test-write
```
#### **Common Error: SELinux Denial**
```bash
# Error in logs or journalctl
SELinux is preventing access to 'write' on the file /data/test.txt
```
**Root Cause**: SELinux context not set for container volumes
**Solution**:
```bash
# Option 1: Use :Z labels (recommended - private volumes)
-v ${HMAC_BASE}/data:/data:rw,Z
# Option 2: Use :z labels (shared volumes between containers)
-v ${HMAC_BASE}/data:/data:rw,z
# Option 3: Set SELinux boolean (system-wide change)
sudo setsebool -P container_manage_cgroup on
# Option 4: Manual context setting
sudo semanage fcontext -a -t container_file_t "${HMAC_BASE}(/.*)?"
sudo restorecon -R ${HMAC_BASE}
```
#### **Common Error: User Namespace Issues**
```bash
# Error starting container
Error: can't stat ${HMAC_BASE}/data: permission denied
```
**Root Cause**: User namespace mapping issues in rootless mode
**Solution**:
```bash
# Check user namespace configuration
cat /etc/subuid /etc/subgid | grep $USER
# If missing, add mappings (requires root)
sudo usermod --add-subuids 1000-65536 $USER
sudo usermod --add-subgids 1000-65536 $USER
# Restart user services
systemctl --user restart podman
# Use podman unshare for ownership
podman unshare chown -R 1011:1011 ${HMAC_BASE}
```
#### **Verification & Testing Commands**
```bash
# Test 1: Verify container can access all paths
podman exec hmac-file-server sh -c '
echo "=== Container User ==="
id
echo "=== Directory Access ==="
ls -la /app /data /deduplication /logs
echo "=== Write Test ==="

#### **Advanced: Custom UID/GID Mapping**
If you need different UIDs (e.g., for existing file ownership):
```bash
# Option 1: Rebuild container with custom UID
podman build -t localhost/hmac-file-server:custom \
--build-arg USER_UID=1500 \
--build-arg USER_GID=1500 \
-f dockerenv/podman/Dockerfile.podman .
# Option 2: Use --user flag (may have limitations)
podman run --user 1500:1500 [other options] localhost/hmac-file-server:latest
# Option 3: Host ownership adjustment
sudo chown -R 1500:1500 ${HMAC_BASE}
```
#### **Docker vs Podman Ownership Differences**
| Scenario | Docker | Podman Rootless | Podman Rootful |
|----------|--------|-----------------|----------------|
| **Host UID** | 1011:1011 | 1011:1011 | 1011:1011 |
| **Container UID** | 1011:1011 | 1011:1011 | 1011:1011 |
| **Volume Ownership** | `chown 1011:1011` | `podman unshare chown 1011:1011` | `chown 1011:1011` |
| **SELinux Labels** | `:Z` or `:z` | `:Z` or `:z` | `:Z` or `:z` |
### Podman Deployment Script Features
The `deploy-podman.sh` script provides complete automation:
- **✅ Interactive deployment** with colored output
- **✅ Auto-generates secure configuration** with random HMAC/JWT secrets
- **✅ Security-hardened settings**: `--cap-drop=ALL`, `--read-only`, `--no-new-privileges`
- **✅ Pod management** for XMPP integration
- **✅ Health monitoring** and status reporting
- **✅ Environment variable support** for customization
### Podman Commands Reference
```bash
# Build image
podman build -t localhost/hmac-file-server:latest -f dockerenv/podman/Dockerfile.podman .
# Run with basic settings
podman run -d --name hmac-file-server \
-p 8888:8888 \
-v ./config.toml:/app/config.toml:ro \
-v ./data:/data:rw \
localhost/hmac-file-server:latest -config /app/config.toml
# Create and manage pods for XMPP integration
podman pod create --name xmpp-services -p 8888:8888 -p 9090:9090

```
### Podman Systemd Integration
#### User Service (Rootless - Recommended)
```bash
# Copy service file
cp dockerenv/podman/hmac-file-server.service ~/.config/systemd/user/
# Enable and start
systemctl --user daemon-reload
systemctl --user enable hmac-file-server.service
systemctl --user start hmac-file-server.service
# Check status
systemctl --user status hmac-file-server.service
```
#### System Service (Root)
```bash
# Copy service file
sudo cp dockerenv/podman/hmac-file-server.service /etc/systemd/system/
# Enable and start
sudo systemctl daemon-reload
sudo systemctl enable hmac-file-server.service
sudo systemctl start hmac-file-server.service
```
### Podman with XMPP Integration
```bash
# Complete XMPP + HMAC File Server pod setup
podman pod create --name xmpp-pod \
--publish 5222:5222 \
--publish 5269:5269 \
--publish 5443:5443 \
--publish 8888:8888
# Run Prosody XMPP server
podman run -d --pod xmpp-pod --name prosody \
-v ./prosody/config:/etc/prosody:ro \
-v ./prosody/data:/var/lib/prosody:rw \
docker.io/prosody/prosody:latest
# Run HMAC File Server
podman run -d --pod xmpp-pod --name hmac-file-server \
-v ./hmac/config.toml:/app/config.toml:ro \
-v ./hmac/data:/data:rw \
localhost/hmac-file-server:latest -config /app/config.toml
# Check pod status
podman pod ps
podman ps --pod
```
### Deployment Script Commands
```bash
# Management commands
./deploy-podman.sh deploy # Full deployment (default)
./deploy-podman.sh start # Start services
./deploy-podman.sh stop # Stop all services
./deploy-podman.sh restart # Restart services
./deploy-podman.sh status # Show service status
./deploy-podman.sh logs # Show container logs
./deploy-podman.sh config # Show configuration
./deploy-podman.sh build # Build container image only
./deploy-podman.sh pod # Create pod only
./deploy-podman.sh clean # Remove containers and image
./deploy-podman.sh help # Show help
# Environment variables
export APP_DATA="/custom/path/hmac-file-server"
export LISTEN_PORT="9999"
export METRICS_PORT="9998"
./deploy-podman.sh
```
### Podman Security Features
#### Container Security
- **Rootless operation**: Runs as non-root user (UID 1011)
- **Capability dropping**: `--cap-drop=ALL`
- **No new privileges**: `--security-opt no-new-privileges`
- **Read-only filesystem**: `--read-only` with tmpfs for /tmp
- **SELinux labels**: Volume mounts with `:Z` labels
#### Network Security
- **Pod isolation**: Containers run in isolated pods
- **Port binding**: Only necessary ports exposed
- **Health monitoring**: Built-in health checks
### Troubleshooting Podman
#### Common Issues
**Permission Errors:**
```bash
# Fix SELinux contexts
restorecon -R /opt/podman/hmac-file-server
# Check volume permissions
podman unshare ls -la /opt/podman/hmac-file-server
```
**Container Won't Start:**
```bash
# Check image exists
podman images | grep hmac-file-server
# Validate configuration
./deploy-podman.sh config
# Debug with interactive container
podman run -it --rm localhost/hmac-file-server:latest /bin/sh
```
**Network Issues:**
```bash
# Check pod networking
podman pod ps
podman port hmac-file-server
# Test connectivity
nc -zv localhost 8888
```

# HMAC File Server - Podman Configuration Examples
This directory contains Podman-specific deployment files for HMAC File Server 3.2 "Tremora del Terra".
## 🚀 Quick Start
```bash
# Clone repository
git clone https://github.com/PlusOne/hmac-file-server.git
cd hmac-file-server/dockerenv/podman
# Deploy with single command
./deploy-podman.sh
# Check status
./deploy-podman.sh status
# View logs
./deploy-podman.sh logs
```
## 📁 Files Overview
### `Dockerfile.podman`
- **Purpose**: Optimized Dockerfile for Podman deployment
- **Features**:
- Security-hardened Alpine-based image
- Non-root user (UID 1011)
- Health checks included
- Static binary compilation
- Minimal attack surface
### `deploy-podman.sh`
- **Purpose**: Complete deployment automation script
- **Features**:
- Interactive deployment with colored output
- Automatic configuration generation with random secrets
- Security-hardened container settings
- Pod management for XMPP integration
- Health monitoring and status reporting
### `hmac-file-server.service`
- **Purpose**: Systemd service unit for service management
- **Usage**: Place in `~/.config/systemd/user/` (rootless) or `/etc/systemd/system/` (system-wide)
## 🛠️ Deployment Commands
### Basic Deployment
```bash
# Full deployment (directories, config, build, start)
./deploy-podman.sh deploy
# Start services only
./deploy-podman.sh start
# Stop all services
./deploy-podman.sh stop
# Restart services
./deploy-podman.sh restart
```
### Management Commands
```bash
# Check status and health
./deploy-podman.sh status
# View real-time logs
./deploy-podman.sh logs
# Show current configuration
./deploy-podman.sh config
# Build image only
./deploy-podman.sh build
# Create networking pod only
./deploy-podman.sh pod
# Complete cleanup (keeps data)
./deploy-podman.sh clean
```
## 🔧 Configuration
### Environment Variables
```bash
# Custom data directory
export APP_DATA="/custom/path/hmac-file-server"
# Custom ports
export LISTEN_PORT="9999"
export METRICS_PORT="9998"
# Deploy with custom settings
./deploy-podman.sh
```
### Generated Configuration
The deployment script generates a production-ready configuration with:
- ✅ **XMPP-compatible file extensions**
- ✅ **Random HMAC and JWT secrets**
- ✅ **Optimized performance settings**
- ✅ **Security hardening enabled**
- ✅ **Comprehensive logging**
## 🔒 Security Features
### Container Security
- **Rootless operation**: Runs as non-root user (UID 1011)
- **Capability dropping**: `--cap-drop=ALL`
- **No new privileges**: `--security-opt no-new-privileges`
- **Read-only filesystem**: `--read-only` with tmpfs for /tmp
- **SELinux labels**: Volume mounts with `:Z` labels
### Network Security
- **Pod isolation**: Containers run in isolated pods
- **Port binding**: Only necessary ports exposed
- **Health monitoring**: Built-in health checks
## 🔄 Systemd Integration
### User Service (Rootless - Recommended)
```bash
# Copy service file
cp hmac-file-server.service ~/.config/systemd/user/
# Enable and start
systemctl --user daemon-reload
systemctl --user enable hmac-file-server.service
systemctl --user start hmac-file-server.service
# Check status
systemctl --user status hmac-file-server.service
```
### System Service (Root)
```bash
# Copy service file
sudo cp hmac-file-server.service /etc/systemd/system/
# Enable and start
sudo systemctl daemon-reload
sudo systemctl enable hmac-file-server.service
sudo systemctl start hmac-file-server.service
# Check status
sudo systemctl status hmac-file-server.service
```
## 🎯 XMPP Integration
### Pod-based XMPP Deployment
```bash
# Create XMPP services pod
podman pod create --name xmpp-services \
--publish 5222:5222 \
--publish 5269:5269 \
--publish 5443:5443 \
--publish 8888:8888
# Add Prosody XMPP server
podman run -d --pod xmpp-services --name prosody \
-v ./prosody-config:/etc/prosody:ro \
-v ./prosody-data:/var/lib/prosody:rw \
docker.io/prosody/prosody:latest
# Add HMAC File Server
podman run -d --pod xmpp-services --name hmac-file-server \
-v ./config.toml:/app/config.toml:ro \
-v ./data:/data:rw \
localhost/hmac-file-server:latest -config /app/config.toml
```
## 📊 Monitoring and Health
### Health Checks
```bash
# Manual health check
curl -f http://localhost:8888/health
# Container health status
podman healthcheck run hmac-file-server
# Continuous monitoring
watch -n 5 'curl -s http://localhost:8888/health && echo " - $(date)"'
```
### Metrics
```bash
# Prometheus metrics
curl http://localhost:9090/metrics
# Pod statistics
podman pod stats xmpp-pod
# Container logs
podman logs -f hmac-file-server
```
## 🚨 Troubleshooting
### Common Issues
#### Permission Errors
```bash
# Fix SELinux contexts
restorecon -R /opt/podman/hmac-file-server
# Check volume permissions
podman unshare ls -la /opt/podman/hmac-file-server
```
#### Container Won't Start
```bash
# Check image exists
podman images | grep hmac-file-server
# Validate configuration
./deploy-podman.sh config
# Debug with interactive container
podman run -it --rm localhost/hmac-file-server:latest /bin/sh
```
#### Network Issues
```bash
# Check pod networking
podman pod ps
podman port hmac-file-server
# Test connectivity
nc -zv localhost 8888
```
### Log Analysis
```bash
# Container logs
podman logs hmac-file-server
# Application logs
tail -f /opt/podman/hmac-file-server/logs/hmac-file-server.log
# System journal
journalctl --user -u hmac-file-server.service -f
```
## 🎉 Success Verification
After deployment, verify everything works:
1. **Health Check**: `curl -f http://localhost:8888/health`
2. **Metrics**: `curl http://localhost:9090/metrics`
3. **Container Status**: `podman ps`
4. **Pod Status**: `podman pod ps`
5. **Logs**: `./deploy-podman.sh logs`

# 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
