- Add unique source port per packet to avoid conflicts and improve reliability - Implement configurable retry mechanism with -r/--retries flag (default 1) - Add packet timing delays to mitigate rate limiting: - 0.2ms delays between initial packets - 1ms delays between retry packets - 50ms wait for initial responses, 100ms for retry responses - Improve response tracking with proper synchronization - Add comprehensive port accounting to ensure no ports are missed - Better duplicate detection and port state management - Add reliability tests and documentation These improvements address issues like the one reported with 104.36.195.221:80 where ports were being missed due to: - Source port conflicts - Rate limiting by target hosts - Packet loss without retries - Timing issues in response collection The retry mechanism and improved timing should significantly reduce missed ports on difficult hosts.
