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.做皇帝，这是一个巨大的诱惑，项羽怎么会轻易放弃。庞夫人当即笑道，可这么算下来，沿海的几里，可都是你家的了。我娘就拿了不少，还有刘家是大舅爷亲家，也送了些。故事发生在民国初年，天津静海县武术世家“华全艺”传人华五岳有一子名华震洋，震洋乃武学奇才，曾遇江湖独行大侠石黑龙指点，从此展开其传奇的一生。年轻气盛的华震洋，独闯天津，凭一身功夫，结识了车夫晋松、李大牛，更被爱国志士祈学礼看重。华震洋在天津看到美、俄、日、英等列强耀武扬威，欲借打擂台欺压中国人，非常气愤，在擂台上打败大力士，名声大噪。震洋在天津认识施婷婷，王芙蓉两女，施婉婷钟情于华震洋，怎奈她性格高傲，并不表露。华家人中意王芙蓉。王芙蓉为救华震洋更是身负重伤，令他十分感动，于是，施婉婷无奈黯然退出。祈学礼曾在日本留学，并与日本姑娘顺子育一子祈向中。顺子把祈向中带到中国交与祈学礼。祈向中因是混血儿，在日本屡受同学排斥，思想偏激，他本想学武扬威，却发现华震洋的人品、武功皆在自己之上，父亲祈学礼经常以震洋为祈向中的榜样，令祈向中心中很不满，祈向中对施婷婷一见钟情，但她却忘不了华震洋，令祈向中对震洋更为眼红，祈向中在游长城时遭日本旧同学的欺辱，令祈向中变得自卑而乘戾，他为了出人头地投靠日本的永濑8.
