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.泰瑞莎（罗宾-莱特饰）一日在海边慢跑时，无意发现了一个埋在白沙中的玻璃瓶，瓶内装着一封属名G的信。泰瑞莎反覆看了又看，深深被信中G的热情及真爱所打动了。她好奇着，是怎么样的感情，能让一个人如此心痛。解放战争时期，我军转战陕北的一个冬天，俘虏了一个叫金大义的国民党骑兵并将他转交给当地政府，后被安排到李家崖村。村里人得知拉回来的伤员是个俘虏兵时，谁都不愿意接受，一位质朴善良的大嫂受命收留了他。大嫂的丈夫在前线作战，家中只有她和六岁的女儿秀秀。这要是有个好歹，老人家也活不成了。Elevator TensionDown Arrow Down Arrow-
