H278 Tor Network Client

Educational Project Notice: This is an educational project created to demonstrate and learn how Go interacts with shared memory across different operating systems. The implementation serves as a learning resource for understanding cross-platform shared memory management and network programming in Go.

A high-performance, multi-circuit Tor network client implementation in Go with cross-platform shared memory support.

Overview

H278 is a sophisticated network client that enables concurrent HTTP requests through multiple Tor circuits while maintaining cross-platform compatibility for shared memory operations. The application is designed to handle high-throughput network requests with IP rotation capabilities and comprehensive logging.

Educational Purpose

This project was created to:

• Demonstrate shared memory implementation in Go
• Show cross-platform compatibility approaches
• Illustrate system-level programming concepts
• Provide practical examples of Go's syscall interfaces
• Showcase proper error handling and resource management

Key Features

• Multiple concurrent Tor circuits management
• Cross-platform shared memory implementation (Windows/Unix)
• Automatic IP rotation
• Request queuing and processing
• Comprehensive logging and monitoring
• Graceful shutdown handling

System Requirements

• Go 1.23.2 or higher
• Tor service installed and accessible in system PATH
  • For Unix/Linux: sudo apt-get install tor (Debian/Ubuntu)
  • For Windows: Download and install from the official Tor website
  • Verify installation with tor --version in terminal/command prompt
• Compatible with Windows and Unix-based systems

Architecture

Core Components

Network Package (/network)

• MultiTorClient: Manages multiple Tor circuits
• TorCircuit: Individual Tor circuit implementation
• Request: HTTP request abstraction

Memory Package (/Memory)

• Platform-specific shared memory implementations
• Unified interface through SharedMemoryInterface
• Separate implementations for Windows and Unix systems

Service Package (/service)

• ResponseLogger: Handles request logging and monitoring
• Manages client lifecycle and request processing

Memory Management

The application implements a cross-platform shared memory system:

• Unix Implementation: Uses POSIX shared memory (shm_open)
• Windows Implementation: Uses Windows memory-mapped files
• Abstract interface ensuring consistent behavior across platforms

Dependencies

require (
    github.com/cretz/bine v0.2.0
    golang.org/x/net v0.31.0
    golang.org/x/sys v0.27.0
    golang.org/x/crypto v0.29.0
)

Configuration

Shared Memory

sharedMemName := "h278"    // Shared memory identifier
sharedMemSize := 1024*1024 // 1MB size

Network Settings

• Default request interval: 5 seconds
• Random delay between requests: 600-800ms
• Circuit count: 4 (configurable)

Usage

Basic Implementation

package main

import (
    "H278/service"
    "log"
)

func main() {
    logger, err := service.NewResponseLogger(
        "your-target-url",
        "h278",    // Shared memory name
        1024*1024, // Shared memory size
    )
    if err != nil {
        log.Fatal(err)
    }
    defer logger.Stop()

    logger.Start()
    // ... handle shutdown
}

Request Configuration

request := network.Request{
    URL:    targetURL,
    Method: "POST",
    Body:   jsonBody,
    Headers: map[string]string{
        "Connection":   "keep-alive",
        "User-Agent":   "H278",
        "Content-Type": "application/json",
    },
}

Testing

The application includes comprehensive test suites:

Client Tests (/tests/Client_test.go)

• Circuit initialization
• IP rotation
• Request processing
• Error handling

IP Change Tests (/tests/IpChange_test.go)

• Tor connection validation
• IP rotation verification
• Response timing tests

Run tests using:

go test ./tests/...

Security Considerations

Network Security

• All requests are routed through Tor circuits
• Automatic IP rotation for anonymity
• Configurable request delays to prevent detection

Memory Security

• Secure shared memory implementation
• Proper cleanup on shutdown
• Memory access permissions handling

Error Handling

• Circuit initialization failures
• Network request errors
• Shared memory errors
• Graceful cleanup on failures

Performance Considerations

• Concurrent circuit management
• Configurable delay between requests
• Memory-efficient shared data handling
• Automatic resource cleanup

Limitations

• Requires local Tor service installation
• Memory size limited by system constraints
• Network performance dependent on Tor network

Best Practices

Configuration

• Adjust shared memory size based on requirements
• Configure appropriate request delays
• Set reasonable circuit count

Monitoring

• Monitor response times
• Track IP rotation success
• Log error patterns

Maintenance

• Regular Tor service updates
• Monitor memory usage
• Review log patterns
