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.克莱夫·里德庆祝自己拿走了丝绸，玛莎却喝得酩酊大醉，她对莱特探长在法庭上撒谎以判她的当事人约翰尼·福斯特有罪感到愤怒。后来，钱伯斯校长艾伦·考德利（alancowdrey）十几岁的儿子大卫（David）因造成一名警察死亡而被捕，这名警察是6名在示威游行中用水壶打死他的警察之一。玛莎相信大卫被赖特欺负认罪，并希望艾伦参与他儿子的案子，但大卫并不想见到他的父亲。读者和卡罗琳·沃里克同意帮助玛莎，她在闭路电视上看到一个匿名男子在拘留期间与大卫通话，但没有这次会面的记录。在法庭上，她面对赖特，这一次决心击败他，但证据显示，削弱了玛莎的十字军东征。
