I won't repeat much about the profound and pure theoretical explanation here. After all, the written explanation is too lenient. I'm going to say something simple and visible here. Let's start now.何风策马来到战场，大大地夸奖了所有的军士。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.退休军队老干部葛定国同志被组织“管理”了一辈子，退休后突然改变了主意，把“为自己活一把”，硬是和战争中结合的老伴戴冰离了婚，找了个比自己小二十岁的老伴苗岭秀，结果带来了一系列家庭问题，生活从此变得充满幽默……葛家儿女共三个，都是葛定国同志与前任妻子戴冰革命浪漫主义的结晶，他们对于父亲的选择，各自态度不同，老大南征是铁杆的保妈派，对老爷子大打出手；老二北战是个利欲熏心的商人，自己的事都忙不过来，哪有闲工夫去管老爹的事；女儿老三西西最孝顺，也是父亲的心头肉，却与父亲的小老伴水火不容、针锋相对，由此产生出了无数故事……Introduction: It can make the sound of "dance" or "dance" in Korean.
