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.The chairman of MDT meeting makes the final discussion decision, ensures the implementation of the final diagnosis and treatment plan, and clearly defines the necessity of organizing the discussion again;　　"Showtime"曾被用作剧名，表示湖人队的"showtime era"。但由于与美国有线台Showtime撞名，并且该台是HBO竞争对手，剧集为避免混淆而放弃了沿用书名。这是一部讲述转生为人的头形录音机·虚拟头麦克风的“我君”和隶属于ASMR部、以“ASMR甲子园”为目标的女高中生·百合等人展开的闹剧。What is special is the special skill of armor protection.TelecommunicationsThe responsibility chain pattern describes how requests are passed along a chain of objects. It forms objects into a chain, and the sender sends the request to the first receiver of the chain and passes it along the chain until there is an object to process it or until there is no object to process and it remains at the end of the chain.
