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.宋家大院的男主人公宋国生临终前，交给大女儿宋雅梅一块黄连，嘴里叨唠着梅正秋的名字，然后撒手人寰。宋家大院办丧事，大姑爷周长山坚持按老爷子生前的即定方针办，给老爷子穿戏服火化，岳母和小舅子另有主张，双方各不相让，发生激烈冲突。周长山是个三轮车夫，脾气耿直，点火就着，岳母张爱琴从心眼不待见他。二姑爷温左强是个书商，文化公司总经理，头脑灵活，做事不择手段。两个姑爷的脾气禀性截然不同，但因为做了宋家的姑爷，两个自然成了担挑。表面上，温左强对周长山客客气气，但从骨子里看不起他。周长山却是实诚人，对温左强这个有本事的大能人打心眼里　　两年前，云家曾召麦青山出诊，为柳若水之表妹银娃用针，未几，银娃暴毙，其足底亦有金针两枚。而潇湘女死前一日，悦来客栈女少东海棠亲眼见云三少出入潇湘女之闺房，而银娃死于山庄亦与云三少有所瓜葛，麦青山之女麦玉芝(俞小凡饰)为寻证据还父清白，遂应云三少之邀上山小住以便雕刻一座碾玉观音。初上山，麦玉芝颇警觉，惟云三少一派风流，轻怜蜜爱， 麦玉芝一瓣芳心几为动摇。所幸山庄又酿惨案，美女金兰花于盛宴中一命呜呼，双足亦见毒头金针，麦玉芝抽丝剥茧，自忖三少有重大嫌疑，加上佟林布下天罗地网，三少遂辗转被擒伏首认罪，直供金针夺命不讳，麦青山因而放出狱，不料经佟林再三核对人证物证之下.....只是这和谈要是就这么结束了，那么之前的谋划和妙计全都将前功尽弃。哪还有那么多考生。从害人不浅的发薪日贷款到尾气排放测试作假的汽车，这部调查类剧集揭露了企业厚颜无耻的贪腐行径。这是一个关于“真实”的故事，这里有面对危急时刻人性的真实，有面对利益时现实的真实，有面对巨大诱惑时感情的真实……身处浮华都市，真实是一种放弃还是得到？真实能否战胜虚伪？真实的爱情，会实现吗？ 　　家境贫困的潘玉龙是旅游管理专业毕业的大学生，母亲重病令他不得不休学打工，以赚取学费，后来在邻居兼女友汤豆豆的资助下重新回到了学校。毕业后，潘玉龙考入全国最好的五星饭店——万乘大酒店，并阴差阳错地做了住店的，韩国时代公司新任董事长钟顺喜的贴身管家。故事就围绕着潘玉龙和汤豆豆、钟顺喜，以及暗恋他的女孩杨悦之间展开。
