Actually, udp is a weird one. "CLOSED" means that you received an ICMP destination port unreachable message. If you get no response its "OPEN|FILTERED" since not all udp applications send a response back to a UDP packet that was received. "OPEN" is a weird one that I think you get if you reach a UDP enabled application that responds to packets. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. _______________________________________________ Discuss mailing list [hidden email] http://lists.blu.org/mailman/listinfo/discuss
