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.Regarding China's economic development, the 19th National Congress of the Communist Party of China made an important judgment, that is, China's economy has changed from a stage of high-speed growth to a stage of high-quality development, and is now in a key research period of transforming its development mode, optimizing its economic structure and transforming its growth power.** Gel破烂王》根据辽宁本溪的一个真人真事改编，讲述改革开放初期，一群废品收购人员创业的事迹。一个破烂王收破烂起家，后来成为了一家钢铁公司的老板。刘蓓在剧中饰演破烂王的女儿，起初被分配到文化馆工作，后来文化馆一个工作人员追求她，她没有同意，结果被人挤兑，调到收破烂的公司。在新的工作单位，这个人物经历了从一开始特别抵触、到后来干得特别投入、特别出色的这么一个过程。Submarine main valve open
