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.邵氏当年的大制作《射雕英雄传第三集》阵容鼎盛，在多位红星坐镇下，令吸引力倍增。影片由傅声及恬妞当郭靖黄蓉，本性鬼马的傅声饰演憨直郭靖表现突出，恬妞生动传神的演绎方式也带来不少轻松场面；狄龙饰演南帝段王爷的威风形象，成为片中焦点人物。《射雕英雄传》乃金庸名著，故事由大导演张彻与名作家倪匡改编，剧情比原著更丰富；张彻执导的出色武打场面，令人看得津津有味。
