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.Christian Serratos会在《莎丽娜 Selena: The Series》一剧中饰演墨西哥裔已故歌手Selena Quintanilla。这部剧由Netflix开发，被指是Selena Quintanilla的官方故事，剧中讲述她为了成为歌手的成长﹑痛苦﹑改变，如何从事业﹑家人﹑音乐中取得平衡。********四散在山野间搜寻青鸾公主的南雀**士忽然发现一个蒙着面纱的女子在半山腰仓皇奔逃，两个男人提剑在后追赶。5.
