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.影片讲述了四位好姐妹一起去新奥尔良参加音乐节，姐妹们的热情被重新点燃后一起歌舞和疯狂的故事。许悦是一位受过良好传统教育的80后，事隔十年他与小时候一起长大，后移民美国的邻家妹妹米恩再次相遇，米恩租下了许悦隔壁的房子，两个人再度开始了邻居生活。米恩从小就喜欢许悦，且为了许悦而回国，许悦却只将米恩当妹妹看待，米恩选择默默地陪在许悦身边。许悦在经历感情欺骗、事业失利、亲戚朋友疏远之后，一度对自己从小受父亲教育影响的做人处世方式产生了怀疑，对当今社会上的诸多不良现象由不满变为妥协，开始变得自私自利。米恩了解许悦所经历的一切，不懈开导和帮助许悦，让许悦重新找回做人的方向。在两人相处过程中，许悦逐渐意识到自己对米恩的情感已经开始发生变化，他们在忙碌的工作之余、在生活的点滴小事中不断积累情感，最终修成正果。Come and join Binjiang Environmental Protection QQ Group: 202412159 or
