Yes there is, but not by using SYN scanning because there will always be a reply to the SYN (either SYN/ACK or RST). Try sending FIN's istead of SYN's to the host. If the port is closed the id should increment by 512, and by 256 if it's open. -- Filipe Almeida aka LiquidK ---------------------------------------------------------------------------- This list is provided by the SecurityFocus Security Intelligence Alert (SIA) Service.
