SYN attack is a kind of DOS attack. 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.　　富家子弟Thanat（Ananda饰演）误打误撞与特技替身演员Vina（Baifern饰演）结缘，两人之间的爱情因为经济水平和社会地位的巨大差异而困难重重。机缘巧合下，两人灵魂互换，体验各自的人生，感情也从一开始的互相试探与怀疑到至死不渝……詹妮·库珀，前急诊室医生和新任命的验尸官，调查可疑死亡。珍妮患有焦虑症，最近与一个十几岁的儿子丧偶，她是一个行动的女人，被对真相的强烈渴望所驱使。抗日战争时期，因为被人出卖，鬼子屠村，葛二蛋村子里的一百五十多人全部被杀害。葛二蛋（黄渤 饰），麦子（高虎 饰）和苗子（方慧 饰）成了这场劫难中侥幸存活下来的人，寻找背叛者报仇成了三人的使命。在生死关头挣扎，在命运面前抉择，三人不同的性格让他们走上了三条不同的道路。葛二蛋侠肝义胆，聪明机灵，为了复仇加入了八路军，并找到了自己未过门的媳妇孟喜子（童瑶 饰）。苗子因与救命恩人的情爱纠葛，选择了在丈夫培养下成为一名国民党特务。而胆小怕事，自私自利的麦子最终也投靠了日本人，为了私利残杀昔日的亲人。与此同时，就在抗日战争局势开始逐渐明朗化的时候，背叛村子的人出现了，竟然是葛二蛋的父亲，一心复仇的葛二蛋又该如何面对正义和亲情的抉择？(Update 11.29)　　组织成员多年前已南下香港，亦融入香港社会。某日，七金刚当年得师傅从中国来香港造访七人，要求他们参与一件中日交易事件，目的为夺取两张电脑软件。
