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.现在找他谈合作，刘邦自然是最为乐意，正是求之不得的好事情。影片讲述的是一位高富帅高凡与好友王军山和几位美女一同游玩勉县定军山时，意外穿越到三国时代,邂逅了诸葛亮之女诸葛勉，由于两人生活时代的不同，彼此渐渐暗生情愫，诸葛勉更是陷入情网不能自拔，而就在此时，面对爱人的即将离去，诸葛勉将何去何从，两人经历了一场穿越时空的生离死别。胡钊想起黄瓜抱进美味斋的那个黑小孩，刚想进去，忽听街头传来马蹄声，眼珠一转，扯着美味斋的掌柜一起跟衙役走了。Reuse code. ?
