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.故事围绕伦勃朗(基顿饰)和安娜(李美琪饰)展开,这两个世界上最顶级的杀手将揭露一段发生在越南的神秘往事。多年来,他们游遍全球来互相争夺最抢手的合同。但当安娜的导师穆迪(杰克逊饰)被谋杀时,她和伦勃朗必须结盟,返回越南追捕凶手。《庸俗一族》的原作是由小山由加利在Kiss上连载的同名漫画。描写了从平民家庭嫁到上流社会一族的筱原佐都，被不讲理的惯例和亲属间复杂的人际关系所玩弄，与丈夫一起奋斗的故事。
