Half-connection survival time: refers to the longest survival time of entries in the half-connection queue, that is, the longest time from receiving SYN packet to confirming that this message is invalid. This time value is the sum of the longest waiting time of all retransmission request packets. Sometimes we also call the half connection survival time Timeout time and SYN_RECV survival time.The sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.　　Katriya有个要好的未婚夫Sophon,而Jeeranan则是悄悄的爱上了这位准姐夫.Jeeranan把这份感情藏匿了起来.曾经富甲一方的武状元苏灿遭遇陷害痛失一切，后被一乞丐所救，坎坷磨炼中练得绝技，终成一代醉拳宗师。Http://blog.csdn.net/zhuming3834/article/details/72778147　　林绍涛阴差阳错地回到了VG，这里曾是他事业的起点，而简艾也被邀请到该公司任职。缘份让他们在同一家公司里共同经历着许多事，从另一个角度重新了解彼此，欣赏彼此。电影《我的上高》以上高会战为背景，再现了上高会战时期，上高普通民众支援抗战、痛击日本侵略者的一段感人故事。闻名中外的“上高会战”又称“上高战役”或“锦江会战”，被称为是上世纪抗战以来最精彩的一战：1941年3月，驻南昌的34师团大岛茂因友邻第33师团预定要调到华北，要求33师团走前配合自己扫荡周围的中国军主力，却因两个师团严重不配合导致34师团扎进4个中国军的合围圈，是为“上高战役”。中国军队统计击毙日军大佐联队长滨田以下日军15000余人，日军自报伤亡千余人。
