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.　　艾伦十分迷恋科学家哈里森（汤姆·加瓦那 Tom Cavanagh 饰）所研究的粒子加速器，然而，一场意外让加速器发生了爆炸，艾伦被击中陷入了昏迷。九个月后，终于苏醒的艾伦惊讶的发现自己体内产生了神奇的变化，因此而获得了特殊能力。随着时间的推移，艾伦开始明白，这个世界上，还有很多和自己一样拥有超能力的人存在，而保护市民的安全成为了他新的责任和任务。电影以抗美援朝战争第二次战役中的长津湖战役为背景，讲述了在结束了新兴里和下碣隅里的战斗之后，七连战士们又接到了更艰巨的任务……　　张应酬繁多, 把丁托付给次明及其妻. 次明夫妇决意帮助缚住张不羁的心, 丁更决定采取逐个击破的策略, 务求要把张的女朋友一一打发.电影《我不是王毛》描述了豫东地 区一个酿酒人家的悲欢离合。主人公狗剩为了娶 自己心爱的女人为妻，自己卖自己，冒名顶替一 个叫‘王毛’的‘憨瓜’，三次卖到部队，又三次当‘逃 兵’。故事情节跌宕起伏，时而让人捧腹大笑，时 而让人唏嘘不已。影片充分反映了那个年代社会 底层的无奈与挣扎，发人深省。灰色幽默，啼笑 皆非。
