Release v2.3.0

Release Notes

This release enhances DTail's SSH authentication capabilities by adding support for direct private key file authentication, providing users with more flexible authentication options beyond SSH agent-based methods.

🔧 New Features

Direct SSH Private Key Authentication

  • Added --key parameter to all DTail commands (dtail, dgrep, dcat, dmap, drun)
  • Specify private key files directly using --key /path/to/private/key without requiring SSH agent setup
  • Streamlined authentication for environments where SSH agents are not available or preferred

🚀 Improvements

Enhanced SSH Authentication Flow

  • Improved authentication method priority: Custom private keys take precedence, followed by SSH agent, then default key locations
  • Better error handling with clearer messaging when authentication methods fail
  • More robust key discovery that gracefully falls back through multiple authentication options

Code Quality & Architecture

  • Refactored SSH authentication logic for better maintainability and extensibility
  • Enhanced logging with more detailed debug information for troubleshooting authentication issues
  • Consistent parameter handling across all command-line tools

📚 Documentation

  • Updated quickstart guide with comprehensive SSH authentication setup instructions
  • Added private key authentication examples showing both SSH agent and direct key file usage
  • Clarified authentication method selection to help users choose the best approach for their environment

🔄 Migration Notes

This release is fully backward compatible. Existing SSH agent-based authentication continues to work without any changes. The new --key parameter is optional and provides an additional authentication method for users who prefer or require direct private key file access.

🛠️ Technical Details

  • Enhanced SSH client initialization with support for multiple authentication strategies
  • Improved connection handling and error reporting for authentication failures
  • Updated all command-line interfaces to support the new private key parameter consistently
