令狐冲出剑，迎上了赶来的黑木崖高手。We all know that computers have a certain security protection system. Through the security protection system, computers can detect certain abnormal viruses and give reminders and removals. The DDOS attacker achieves its goal by evading this protection system and carrying out a rejection attack on the computer, thus bringing the other computer into its own control.　　《梅森探案集》中的主人公梅森，就像作者加德纳本人一样，是一位刚正不阿的律师，在小说中自称要“全力以赴地为我的委托人而战”，“我的特长就是拼博”，因此他常在法庭快要定案宣判时，出其不意地提出确凿证据为被告辩护，使无辜者开脱，案情真相大白。这些探案另一特点是作者特别注重法医在侦察过程中搜集和保存证据的重要性，从而判定死者是意外死亡，抑或自杀，还是被谋杀，以免误判造成冤案错案。加德纳为此在好几本小说的序言中都着重强调了这一点，并把著作献给他的一些好友——技能高超、经验丰富的杰出法医学专家。总之，《梅森探案集》的小说情节篇篇曲折紧张，扑朔迷离，扣人心弦，使读者读来兴趣盎然，同时又可以使读者对美国光怪陆离的社会现实面貌，形形色色的案件，尤其是对美国的法律、刑事法庭审讯的法制、律师制度等诸多方面增进了解。厄尔·斯坦利·加德纳是一位擅长写法庭侦探（—译公堂戏剧性派）小说的高手。他一生写了146 部著作，其中最引人入胜的是以律师佩里·梅 森为主人公的85 部探案小说，每部均在美国销售百万余册，而这套小说全球总销量已超过三亿册。美国影视界自1957 年把他的这些小说陆续改编成电视连续剧《佩里·梅森》，由著名影星雷蒙德·布尔主演，一连放映达8年之久，更使梅森律师成为美国家喻户晓的人物。When the SYN gateway receives the SYN packet from the client, it directly forwards it to the server. After receiving the SYN/ACK packet from the server, the SYN gateway forwards the packet to the client and sends the ACK confirmation packet to the server in the name of the client. At this time, the server enters the connected state from the semi-connected state. When the client confirms the arrival of the packet, it forwards if there is data, otherwise it discards it. In fact, the server has a connection queue in addition to maintaining the semi-connection queue. If SYN attack occurs, the number of connection queues will increase, but the number of connections that the general server can withstand is much larger than the number of semi-connections, so this method can effectively reduce the attack on the server.浅浅一碗月牙儿挂在天边，群星璀璨，光芒闪耀。
