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.李越点开自己的个人用户中心，一看之后，发现里面竟然还剩九十九元六毛。故事讲述10岁的小学女生森泽优在偶然机遇下得到魔法后，可以变身成16岁的美少女小甜甜，后来还误打误撞走入演艺界，并成为红透半边天的女歌星。根据作家木子喵喵同名小说改编的剧集《竹马钢琴师》，天娱新晋小花金雯昕出演女主角杨初末。When do we use modular mode?伴马河畔，空降兵某部副营长扬亿与电子专家谷晓楠双人跳伞，突袭“敌”前沿指挥所得手后，取得了电脑指挥系统的关键数据。但由于杨亿的轻敌致使谷晓楠被“敌方”抓获。杨亿被罚到伞训队当教官，负责军直单位女军官补训，这些俏皮的大女孩常常弄得他哭笑不得，大感英雄气短……
