Enable the device to send a TCP segment with the RST (reset) flag set to 1 (one) in response to a TCP segment with any flag other than SYN set … What is a TCP Reset (RST)? | Pico When an unexpected TCP packet arrives at a host, that host usually responds by sending a reset packet back on the same connection. A reset packet is simply one with no payload and with the RST bit set in the TCP header flags.. There are a few circumstances in which a TCP packet might not be expected; the two most common are: Configuring TCP SYN and RST Attack Screen - Technical

TCP Flags. TCP has six flags that can help you troubleshoot a connection. The flags are: U – URG A – ACK P – PSH R – RST S – SYN F – FIN. When using tcpdump command to troubleshoot network connections, you can view TCP conversations with these flags as follows:
TCP Connection Termination (Page 2 of 4) Normal Connection Termination. In the normal case, each side terminates its end of the connection by sending a special message with the FIN (finish) bit set. This message, sometimes called a FIN, serves as a connection termination request to the other device, while also possibly carrying data like a regular segment.
As a comma-separated list of flags, e.g. --flags syn,ack,rst As a list of one-character flag initials, e.g. --flags SAR tells Nping to set flags SYN, ACK, and RST. As an 8-bit hexadecimal number, where the supplied number is the exact value that will be placed in the flags field of the TCP header.
