Heres the updated README.md with the new repository URL and the updated ISO size:


HMAC File Server

HMAC File Server is a secure, scalable, and feature-rich file server with advanced capabilities like HMAC authentication, resumable uploads, chunked uploads, file versioning, and optional ClamAV scanning for file integrity and security. This server is built with extensibility and operational monitoring in mind, including Prometheus metrics support and Redis integration.


Features

  • HMAC Authentication: Secure file uploads and downloads with HMAC tokens.
  • File Versioning: Enable versioning for uploaded files with configurable retention.
  • Chunked and Resumable Uploads: Handle large files efficiently with support for resumable and chunked uploads.
  • ClamAV Scanning: Optional virus scanning for uploaded files.
  • Prometheus Metrics: Monitor system and application-level metrics.
  • Redis Integration: Use Redis for caching or storing application states.
  • File Expiration: Automatically delete files after a specified TTL.
  • Graceful Shutdown: Handles signals and ensures proper cleanup.
  • Deduplication: Remove duplicate files based on hashing for storage efficiency.

Repository


Installation

Prerequisites

  • Go 1.20+
  • Redis (optional, if Redis integration is enabled)
  • ClamAV (optional, if file scanning is enabled)

Clone and Build

# Clone from the primary repository
git clone https://github.com/your-repo/hmac-file-server.git

# OR clone from the alternative repository
git clone https://git.uuxo.net/uuxo/hmac-file-server.git

cd hmac-file-server
go build -o hmac-file-server main.go

Configuration

The server configuration is managed through a config.toml file. Below are the supported configuration options:


Example config.toml

[server]
ListenPort = "8080"
UnixSocket = false
StoragePath = "./uploads"
LogLevel = "info"
LogFile = ""
MetricsEnabled = true
MetricsPort = "9090"
FileTTL = "8760h" # 365 days
DeduplicationEnabled = true
MinFreeBytes = "100MB"

[timeouts]
ReadTimeout = "4800s"
WriteTimeout = "4800s"
IdleTimeout = "4800s"

[security]
Secret = "changeme"

[versioning]
EnableVersioning = false
MaxVersions = 1

[uploads]
ResumableUploadsEnabled = true
ChunkedUploadsEnabled = true
ChunkSize = "8192"
AllowedExtensions = [".txt", ".pdf", ".png", ".jpg", ".jpeg", ".gif", ".bmp", ".tiff", ".svg", ".webp", ".wav", ".mp4", ".avi", ".mkv", ".mov", ".wmv", ".flv", ".webm", ".mpeg", ".mpg", ".m4v", ".3gp", ".3g2", ".mp3", ".ogg"]

[clamav]
ClamAVEnabled = true
ClamAVSocket = "/var/run/clamav/clamd.ctl"
NumScanWorkers = 2
ScanFileExtensions = [".exe", ".dll", ".bin", ".com", ".bat", ".sh", ".php", ".js"]

[redis]
RedisEnabled = true
RedisAddr = "localhost:6379"
RedisPassword = ""
RedisDBIndex = 0
RedisHealthCheckInterval = "120s"

[workers]
NumWorkers = 2
UploadQueueSize = 50

[iso]
Enabled = true
Size = "2TB" # Example ISO size changed to 2TB
MountPoint = "/mnt/iso"
Charset = "utf-8"

Running the Server

Basic Usage

Run the server with a configuration file:

./hmac-file-server -config ./config.toml

Metrics Server

If MetricsEnabled is set to true, the Prometheus metrics server will be available on the port specified in MetricsPort (default: 9090).


Testing

To run the server locally for development:

go run main.go -config ./config.toml

Use tools like cURL or Postman to test file uploads and downloads.

Example File Upload with HMAC Token

curl -X PUT -H "Authorization: Bearer <HMAC-TOKEN>" -F "file=@example.txt" http://localhost:8080/uploads/example.txt

Replace <HMAC-TOKEN> with a valid HMAC signature generated using the configured Secret.


Monitoring

Prometheus metrics include:

  • File upload/download durations
  • Memory usage
  • CPU usage
  • Active connections
  • HTTP requests metrics (total, method, path)

Additional Features

  • Deduplication: Automatically remove duplicate files based on hashing.
  • Versioning: Store multiple versions of files and keep a maximum of MaxVersions versions.
  • ClamAV Integration: Scan uploaded files for viruses using ClamAV.
  • Redis Caching: Utilize Redis for caching file metadata for faster access.

This release ensures an efficient and secure file management system, tailored to environments requiring robust data handling capabilities.

Description
HMAC File Server manages secure file uploads/downloads with HMAC authentication, rate limiting, and auto-banning. It supports CORS, retry options, file versioning, Unix sockets, and Redis integration. Features built-in Prometheus metrics and graceful shutdown for efficient and reliable file transfers.
