Why Saibius?

• Zero-Copy Performance: Leverages sendfile system call for memory-efficient file transfers
• Dynamic Port Allocation: Automatically finds available ports when your preferred port is occupied
• Range Request Support: Resume downloads and stream large files efficiently with HTTP partial content
• Instant Setup: No configuration required - share files in seconds
• Directory Browsing: Beautiful, intuitive web interface for directory navigation
• Smart IP Detection: Automatically displays both localhost and LAN access URLs

Quick Start

Installation

#Generate download links from the Accounts page. Links expire after 10 minutes.
curl -o Saibius {your-download-url}

Basic Usage

Share a directory:

./Saibius --share /path/to/directory

Share a single file:

./Saibius --share /path/to/file.txt

Specify custom port and host:

./Saibius --share /path/to/directory --port 8080 --host 0.0.0.0

Features

Performance Optimizations

Saibius implements several performance optimizations:

Zero-Copy Transfer

• Larger files are streamed using optimized 64KB buffers
• Minimizes memory usage and CPU overhead

Smart Buffering

• Adaptive buffer sizes based on file dimensions
• Asynchronous I/O for non-blocking operations
• Memory-mapped file operations where beneficial

Range Request Support

• Full HTTP/1.1 Range header implementation (RFC 7233)
• Supports seeking in large files and video streaming
• Client-optimized download resumption

Dynamic Network Configuration

Automatic Port Allocation

If your preferred port is busy, Saibius automatically scans for the next available port:

Port 3200 was in use, automatically using port 3201
Server starting at http://127.0.0.1:3201/

Smart IP Detection

Saibius automatically detects and displays your LAN IP for easy network access:

Server starting at http://127.0.0.1:3200/
Server also accessible at http://192.168.1.100:3200/

Command Line Options

Option	Short	Description	Default
--file / --share	-f	Path to file or directory to share	Required
--port	-p	Port to bind to	3200
--host	-h	Host address to bind to	127.0.0.1

Usage Examples

After download binary:

# Share your home directory
./Saibius --share ~/

# Share a specific project
./Saibius --share ./my-project --port 9000

# Make files available on your local network
./Saibius --share ./downloads --host 0.0.0.0 --port 8080

# Share a single large video file
./Saibius --share ./movie.mp4

Integration with curl and wget

Saibius automatically detects command-line tools and provides direct file access:

# Download with curl
curl http://localhost:3200/filename.txt

# Download with wget
wget http://localhost:3200/filename.txt

# Stream with range request (download first 1MB)
curl -r 0-1048575 -o "largefile" http://localhost:3200/largefile.zip

Technology Stack

• Runtime: Tokio asynchronous runtime
• Web Framework: Warp for high-performance HTTP handling
• Core Language: Rust 2024 Edition
• File I/O: Async-optimized with zero-copy support
• Memory Management: Minimal copying with efficient streaming

Key Dependencies

Security Considerations

⚠️ Important: Saibius is designed for trusted network environments and server management tasks. It:

• Serves files without authentication
• Provides open access to shared directories
• Is intended for local network use only
• Should be used behind firewalls in production environments

Directory Features

When sharing directories, Saibius provides:

• Browsable Interface: Clean, responsive web directory listings
• File Metadata: Size display and MIME type detection
• Navigation: Breadcrumb navigation for subdirectories
• URL Encoding: Safe handling of special characters in filenames
• Error Pages: User-friendly 404 and error pages

Error Handling

Saibius implements robust error handling:

• Graceful port conflict resolution
• Comprehensive file permission checks
• Path traversal protection
• Detailed error messages with suggested solutions
