The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.个中国版的《雨人》。1940年，日本占领下的上海，英法德租界成为“孤岛”，一个在教会学校读书，精通英语及法语的18岁数学分析天才，在他的父亲——以租界邮递员身份为掩护的中共地下党员壮烈牺牲后，误打误撞地身陷危险境地，稀里糊涂的成了上海滩谍报界呼风唤雨的人物，一时成为军统特别是日本特高科和汪伪特工竞相关注的焦点。在血雨腥风中，他在他父亲战友的帮助下，历经九死一生，终于成为一名坚定信仰共产主义的谍报专家！该剧环绕着争夺一份名为《蓝石榴》的小说遗稿的种种，将波澜起伏、摄人心魄的故事铺展开来。细致剖析社会各色人等心态，错落变换多个时空，再现了20世纪90年代初北京城乡多个层面的社会风情与生活脉息，描绘出了一系列文化界与市井百姓斑斓多姿的人生图景，予人许多深切联想和启示。闪婚是个现代名词，其形式虽不是现代固有，但多少有点贬意的成份，有拿婚姻当儿戏的意思，至少彼此了解的时间不够充分，这就难免潜在着各种隐患，似乎比其它的婚姻形式更具风险性。闪婚好似一场婚姻赌博，谁都希望赢定它，拥有一生的平安和幸福，可一旦落入情感陷井，又将如何面对……沿途熟悉的旷野，远村近树、阡陌纵横，以及视线尽头的小青山，无不让他感慨万千。玉米得知白凡被拘押，禁不住被轰去魂魄，呆呆的不知所措。
