During the establishment of a tcp connection, If the server returns syn and ack messages, The client does not confirm it for some reason. This is because the server needs to retransmit the syn + ack message and wait for the client's confirmation message until the tcp connection timeout. This state of waiting for the client to confirm the connection is usually called a half-open connection. The half-open connection will be kept in the connection table of the server until the connection is disconnected.
We call a collection of rules that have the same functionality a table, Therefore, we can place rules with different functions in different tables for management, and IPTables has already defined four tables for us, each table corresponds to different functions, and the rules we define cannot escape the scope of these four functions. Therefore, before learning IPTables, we must first understand the function of each table.

1939年初，日寇占领两广，留守坚持作战的东江纵队组建了一支城市行动队。这支部队的战场不在高山和原野，而在光怪陆离的都市。行动队的队员们各个身怀绝技，本领不同。有出身日本军校，擅长各种枪械的队长祈中卫，绰号“中尉”；也有出身大户人家，擅长轻功手雷夺命飞刀的梅彦芳，绰号“一剪梅”；还有忠诚木讷，功夫了得的北方帅哥马振奎，绰号“拐子马”；另有擅长爆破，专治各种不服的的马振奎妹妹马兰兰，绰号“蓝凤凰”；以及风情万种、擅长信息刺探的雷秀梓，绰号“九岁红”和巧舌如簧、擅长化妆套取情报的刘相林，绰号“刘公子”。这样一个小组像古时的剑客，总是潜入敌人的心脏，进行着打击日寇的侵华行动。

通过闪回和闪前，讲述了青春不再的电影导演Alice (Ayelet Zurer)，对年轻编剧Sophie (Lihi Kornowski)日益痴迷。后者黑暗而令人不安的剧本，似乎并不只是虚构故事那么简单。
三则，朝廷轻薄赋税，容易让民众感念皇帝爱民之心，将一腔仇愤转于敌寇，激发其同仇敌忾的爱国之心，强于苛政重赋压榨，使民众离家逃难。
被残忍杀害的年轻女子、被虐的婴儿、被近亲性侵害的女童、家暴阴影下手足无措的妇女、失调扭曲的家庭关系、很想用心但每每力有未迨的父母、杵在社会家庭人际边缘人性的灰色地带。SVU每回总是触动那块让人无从防备的柔软地带，可爱的孩童，无辜的弱势个体(受性侵害者、同性恋、精神病患)，每个人都多少有些经验感触的亲子、家庭关系。不见得得是多复杂的剧情，像今天，忙於工作单亲母亲剧烈摇晃死自己的一岁多幼女(shake syndrome)，幼小无辜的女孩在母亲一时的暴怒下被辗压击碎，但另一方面你多了解那种拉扯在工作亲子关系中的心力交瘁，可爱时像天使哭闹起来却像恶魔一样让你抓狂的孩子，要怎么以审判指控那、为了不舍得看到无恢复希望的孩子继续受到病痛折磨而毅然决定停止呼吸器，哪怕这将使自己已因杀罪被起诉的母亲？是以就算这是再滥情的一种搬演、操控，每每总还是让观众溃不成军..
Law & Order: Special Victims Unit: 对于一部procedural drama来说情节及其设置是成功的关键，L&O: SVU在这方面是相当不错的，同是它也继续着L&O系列的传统：对各个主角的私生活几乎不接触。这样的好处就是可以使观众随时看任意一集而不必担心情节不连续；坏处就是观众群不断更换。Easier to attach, easier to detach. L&O: SVU最大的卖点是sex crime。

Suppose the attacker is in an "interconnected" network (e.g. An Autonomous system? System), whose ISP restricts the input and output filtering of the attacker's network traffic, will be able to prevent this spoofing attack-if this method can be deployed to the correct location by the organization. This defense method of traffic input and output filtering will restrict some legitimate communications, such as the mobile IP triangular routing operation mode, so it cannot be widely deployed. IP Security Protocol (IPsec) also provides an excellent way to resist spoofing packets, but this protocol cannot be used due to deployment restrictions. Since it is usually impossible for the server side to require the ISP of the link initiator to implement address filtering or require it to use IP security protocols, more complex solutions are needed to resist this spoofing attack disguised as multiple addresses, which will be discussed later.
