SOCKS5 Proxy Server Enhancement Roadmap

This document outlines planned improvements and feature enhancements for the SOCKS5 proxy server. Items are prioritized by impact and effort level.

🔴 High Priority - High Impact, Medium Effort

Security & Authentication

  • TLS/SSL Support: Add encrypted connections with --tls-cert and --tls-key flags
  • Advanced Authentication Methods:
    • GSSAPI/Kerberos authentication
    • PAM (Pluggable Authentication Modules) integration
    • LDAP/Active Directory integration
    • JWT token-based authentication
  • Access Control Lists:
    • IP-based allowlists/blocklists with CIDR notation
    • Domain-based filtering
    • User-based permissions
    • Time-based access control

Configuration & Operations

  • Configuration Hot-Reload: Watch config files and apply changes without restart
  • Environment-Based Config Management: Better integration with Kubernetes configmaps/secrets
  • Configuration Validation: Runtime validation with detailed error reporting
  • Multi-Format Logging: Support for log aggregation systems (ELK, Splunk)

Performance & Scalability

  • Connection Pooling: Reuse connections to frequently accessed targets
  • Connection Multiplexing: Handle multiple client connections over single target connection
  • Load Balancing: Support for multiple proxy instances with session affinity
  • Resource Limits: CPU/memory limits and rate limiting per client/IP

🟡 Medium Priority - High Impact, High Effort

Protocol Extensions

  • Complete SOCKS5 Implementation:
    • UDP ASSOCIATE command support (0x03) - Full UDP proxying capability
    • BIND command support (0x02) - Reverse connection proxying
    • IPv6 UDP support with dual-stack operations
    • Socket options handling and negotiation
  • Legacy Protocol Support:
    • SOCKS4/SOCKS4a protocol fallback for compatibility
    • HTTP CONNECT tunneling for HTTPS proxy support
    • SOCKS-over-WebSocket for browser integration

Observability & Monitoring

  • Metrics & Telemetry:
    • Prometheus metrics exporter (/metrics endpoint)
    • Connection counters and latency histograms
    • Per-client statistics and bandwidth tracking
    • Health check endpoints (/_health, /_ready)
  • Advanced Logging:
    • Structured logging with correlation IDs
    • Log rotation and compression
    • Configurable log levels per component
    • Performance profiling integration

Management & APIs

  • Web Management Interface:
    • Real-time connection monitoring dashboard
    • Configuration editor with validation
    • Log viewer with filtering and search
    • Metrics visualization
  • REST API Endpoints:
    • Configuration management API
    • Runtime statistics API
    • Client connection management
    • Administrative controls

🔵 Low Priority - Medium Impact, Low Effort

Developer Experience

  • Enhanced CLI Tools:
    • Auto-completion for shells (bash/zsh/fish)
    • Interactive configuration wizard
    • Progress bars for long operations
    • Help text internationalization (i18n)
  • Testing & Documentation:
    • Integration test framework with real network scenarios
    • Performance benchmarking suite
    • Architecture decision records (ADRs)
    • API documentation generation

Integration & Ecosystem

  • Popular Proxy Chain Integration:
    • Proxychains-ng support
    • Browser extension for testing
    • Mobile apps for configuration
    • Desktop client applications
  • Framework Integrations:
    • Docker container optimization
