The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.那个晚上，我喝醉了酒与谁深情拥吻来着？虽然不记得是谁，但是那个吻...真棒！你到底是谁呢？…一个母胎单身寻找“那个吻”的心动故事！乌丸千岁（千本木彩花 配音）拥有着人见人爱的可爱外表，然而内心里却有着和外貌相差了十万八千里的黑暗和对人类的轻蔑。千岁想要成为一名声优，为了实现理想，她进入了声优事务所工作，却发现展现在眼前的，是一个充满了明争暗斗和尔虞我诈的黑暗世界。燕南天你武功盖世又如何，还是折在老娘手里。(four) other provisions of the medical security management.Birthday date is a holiday, such as Labor Day (0501), Children's Day (0601), National Day (1001) and other holiday dates, the price will also be increased accordingly.唐家霸王枪，是霸者的枪，是霸道的枪，只有进攻，没有后退。
