SYN flooding attacks can attack with fewer packets than ordinary brute-force DoS attacks that only send a large number of packets to the target network. However, this requires some understanding of the server's operating system, such as how much backlog queue space it allocates and how long it will keep the TCB in the SYN-RECIEVED state before timeout and discarding the TCB. For example, an attacker can send a certain number of SYN packets that are exactly the size of the backlog queue, and their cycles are just the time when the TCB is recycled, thus making the server permanently unavailable.与此同时，在USNA的STARS基地，一名少女正准备前往第一高校展开潜入调查。橙黄的布沙发，昏暗的台灯，一墙壁的书，窗外似乎总在下雨，风景模糊，房间里幽暗、安静，只隐约听到钟表指针摆动的声音……每周的第一天到第四天，中年心理医生保罗(加布里埃尔-伯恩 饰)都会在这样的心理咨询室里接待不同却可称为“固定”的四位来访者，每周轮流四次问诊，每次30分钟；周五，保罗会定期约见自己的督导师。在与来访者的互动交流中，保罗与来访者成为朋友，揭开那些有自杀倾向、烟酒成瘾、愤怒或者心虚的来访者心理的秘密，最重要的是在其中保罗也梳理了自己那紧张兮兮、乱成麻的婚姻生活。旗舰率先白旗飘扬，收炮示降，另一艘被围战舰紧随其后。当红电视情感节目主持人聂冰（林嘉欣 饰）在年过三十之际突然感到情感上的困惑：她的父母婚姻失败，母亲（丛珊 饰）整日唠唠叨叨，父亲（朱时茂 饰）娶了聂冰的小学同学，追求者由爱生恨恶语相向……这一切都让她疲惫不堪。赵锋恨声道：肯定不是咱庄户人家。
