In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.38岁的娜塔莎出人意料地生下了一个孩子，她想做什么就做什么的生活戏剧性地崩溃了。这个婴儿控制着娜塔莎，操纵着娜塔莎，用暴力的力量把娜塔莎的生活扭曲成了一场恐怖秀。它来自哪里？它想要什么？娜塔莎为了恢复她的生活需要付出多大的努力？她不想要孩子。婴儿想要她。Unicom顶着“江州第一恶女”名号的郡主刘泠在十八岁生辰这天，与前来江州办差的金麟卫十四千户沈宴不期而遇。刘泠对一本正经的沈宴动了春心，下定决心要把这位美人千户“搞到手”！ 沈宴此来江州，乃是奉东宫旨意，抓捕若干年前发生在江州的一起库银劫案的主犯云奕，此人看似只是个江湖绿林客，背后却牵连着邺京之中的徐、陆两大世家。身为女官的徐氏后人徐时锦父母受江州一案牵连，被扣上了江州案主犯的帽子后便双双亡故，她为替父母洗冤，遂将矛头指向了与江州一案有染的陆家。 云奕一旦落网，陆家必陷入万劫不复之地，陆家庶子陆铭山知道被东宫派去办案的乃是十四千户沈宴，遂向陆公“请战”办妥此事。 江州，沈宴设计诱捕云奕之际，乘车而来的郡主刘泠却意外闯入了包围之中，云奕为制造遁逃的机会，故意惊扰了马车，马车横冲直撞，刘泠跌出马车，沈宴飞身扑救，护着她从山坡上一路滚落。本以为刘泠一定吓坏了，却不想她竟趁机俯身暧昧的对沈宴说了句“沈大人， 又见面了”。02　青　雲此剧改编自日本同名漫画，主要讲述了被迫要求 义务、献身、负责任的大韩民国典型40代家长为了找寻自我，提起勇气选择彷徨而展开的中年喜剧成长故事。Other methods to modify rules: delete rules by number first, and then add a rule at the original number position.
