Greetings... Quick questions about TCP/IP traffic 1. What does it mean when I see a Reset accompanied with an ACK? That is... someone told me that if I see a packet that only has the RESET flag set, this means that the connection was terminated (Or not allowed to establish). But, they said, If I see a packet that contains a RESET with the ACK bit set then although the connection was refused, this is evidence that some service was at least listening enoguh to Acknowlege. 2. Can I assume that when My firewall sends RST that the packet reveals nothing more than the fact that the connection was refused,whether the ACK bit is set or not? 3. If RST was sent and window size is 0 (ACK or no ACK) I conclude that my firewall really does not want to talk... Is this a correct conclusion? -Thanks Hassan
