You send a SYN, and get a SYN/ACK back. A RST/ACK is not an acknowledgement of a RST, same as a SYN/ACK is not exactly an acknowledgment of a SYN.

Receiving host sends a SYN to the initiating host, which sends an ACK back.

RST (1 bit): Reset the connection; SYN (1 bit): Synchronize sequence numbers. Only the first packet sent from each end should have this flag set. Some other flags and fields change meaning based on this flag, and some are only valid when it is set, and others when it is clear. FIN (1 bit): Last packet from sender; Window size (16 bits)
Apr 28, 2010 · If I had it right, Dusty recommended to use FWPM_LAYER_INBOUND_TRANSPORT_V4 and recognize, if RST flag is set. My problem is, that I haven't found any information where to get this RST flag.

TCP Flags TCP has six flags that can help you troubleshoot a connection.

Malvani surnameshping3 Package Description. hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired to the ping(8) unix command, but hping isn’t only able to send ICMP echo requests. 6. Other types of Port Scanning: First type we will try is the FIN scan. In a TCP connection the FIN flag is used to start the connection closing routine. If we do not receive a reply, that means the port is open. Normally firewalls send a RST+ACK packet back to signal that the port is closed..hping3 Package Description. hping is a command-line oriented TCP/IP packet assembler/analyzer.
