SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.

According to the author's investigation, those who use Chinese herbal medicine to eliminate the symptoms of the patient, such as the cancer pain of the patient, have been stopped by Chinese herbal medicine, indicating that the medicine has been effective and the cancer has been cured. Insisting on taking medicine will definitely achieve good results. If western medicine is used to relieve pain, although the pain disappears, it will repeat, and the ability of western medicine to relieve pain will become worse and worse until it is ineffective. Because, Chinese herbal medicine eliminates symptoms is to adjust the balance. The physiological balance of the human body is adjusted, the anti-cancer ability is enhanced, and the cancer will disappear naturally. At the very least, it will stop swelling and endangering life, but coexist with our life. Western medicine can paralyze nerves. This method is equivalent to paralyzing the body's self-adjusted disease resistance. Therefore, once the drug properties are passed, the pain potential will become more severe.
