# GMMC Media Server

A high-performance, public media download server built with Rust and Axum. It is designed to serve extremely large files (100GB+) seamlessly and features a retro, Minecraft-themed web dashboard for easy access.

## Features

- **Blazing Fast & Lightweight**: Powered by Rust, Axum, and Tokio.
- **Large File Optimization**: Streams files using configurable chunk sizes (default 8MB) to handle massive files with low memory footprint.
- **Resume Support**: Full support for HTTP `Range` requests, allowing paused or interrupted downloads to be resumed.
- **Retro Dashboard**: A dynamic, Minecraft-style UI built with vanilla HTML/CSS and the VT323 font. Includes 1-click copy-to-clipboard commands for terminal downloading.
- **No Authentication Required**: Built for public, hassle-free access.
- **Security & Access Control**: Built-in security headers and optional IP whitelisting.

## Prerequisites

- [Rust & Cargo](https://rustup.rs/) (edition 2021)
- A `.env` file for server configuration
- A `media_config.json` file for file registry

## Configuration

### 1. Environment Variables (`.env`)
Create a `.env` file in the root directory:
```env
PORT=3000
HOST=0.0.0.0
# Request timeout in seconds (default 3600 for 1 hour)
REQUEST_TIMEOUT_SECS=3600
# Streaming chunk size in KB (default 8192 for 8MB)
CHUNK_SIZE_KB=8192
# Optional: comma-separated list of allowed IPs
# ALLOWED_IPS=127.0.0.1,192.168.1.100
# Optional: Domain for generating absolute download URLs
# DOMAIN=https://downloads.example.com
```

### 2. Media Registry (`media_config.json`)
Define the files you want to host. Create a `media_config.json` in the root directory:
```json
{
  "files": {
    "ubuntu-iso": {
      "name": "Ubuntu 24.04 LTS",
      "path": "/path/to/ubuntu-24.04-desktop-amd64.iso",
      "description": "The latest LTS release of Ubuntu.",
      "content_type": "application/x-iso9660-image"
    },
    "large-dataset": {
      "name": "AI Training Dataset",
      "path": "./data/dataset.tar.gz",
      "description": "Huge 150GB dataset for machine learning models."
    }
  }
}
```

## Running the Server

1. Clone the repository and navigate to the project root.
2. Build and run the server:
   ```bash
   cargo run --release
   ```
3. Open your browser and navigate to `http://localhost:3000` (or your configured `HOST` and `PORT`).

## Usage

- **Web Dashboard**: Visit the root URL to view available files, their sizes, and descriptions. Click "Download" or copy the provided cURL commands.
- **Direct Download (Browser)**: `http://localhost:3000/download/{file_id}`
- **cURL Download**:
  ```bash
  curl -O http://localhost:3000/download/{file_id}
  ```
  *(For resumable downloads via cURL, add `-C -`)*
