《漂亮的家教3》中文

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.　　这一天注定在一些人的生命里要掀起波澜。萧丞相，既然如此，那你快些出宫去寻找韩信，引荐他来见汉王。　　心黑手辣的朱喜杀掉参与窃宝的人，然后逃往三鸦县，半路被江湖勇士郑天炮截击，不想朱喜的情妇媚娘却乱中携藏宝图——福禄图逃跑。郑大侠中朱喜毒镖，朱喜继续逃亡，诡计多端的朱喜窃喜媚娘偷走的是假福禄图。牛喜夫妇正辛苦打工还债，发现中毒的郑天炮，于是牛喜不顾一切地救活了郑大侠。郑大侠醒来见与朱喜酷肖的牛喜几乎惊呆了，于是拨刀欲再搏斗。We first went to the village committee and obtained the consent of the leaders of the village committee. With their assistance, we arranged a row of tables and stools in the courtyard. Two sphygmomanometers were placed on the table, flyers were posted on the wall, banners were hung and flags were erected. Teacher Zhao informed the villagers to come to the village committee on the radio. After everything was ready, we waited for the villagers to arrive with leaflets, brochures and questionnaires. After the announcement was broadcast, villagers came soon. The students greeted them with smiles, handed out knowledge books to the villagers, explained scientific knowledge to the villagers, and conducted a questionnaire survey. Since most of the villagers could not read, we all asked them one question at a time. It may be easy to do one survey, but it takes great patience to do many. In addition, the villagers generally speak local dialect, and some students have some obstacles in communication, but we have all overcome various difficulties. Some of the students are handing out leaflets, some are answering villagers' questions, some are doing investigations, and some are measuring blood pressure for villagers. The teachers are even more integrated with everyone, and they can no longer tell who is the student and who is the teacher. Gradually, the number of villagers increased, and everyone was even more busy. Look at this lively scene: there are investigations, leaflets, interviews, blood pressure measurements and photos-everyone is really busy! In this way, we successfully completed the task of the first stop.
