In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).　　关羽身长九尺，髯长二尺，面如重枣，唇若涂脂，一身英气，只因杀死富豪，正流浪江湖。张飞身长八尺，豹头环眼，燕颔虎须，声若巨雷，势如奔马，以卖酒杀猪为业，并在本地有一所庄子。三人萍水相逢，但都有为国出力之心，所以一见如故，被张飞拉到自家庄后的桃园饮酒。最后三人对天盟誓，结拜为弟兄，一道去投了刘焉。　　Palai为了报仇，找到了Siwa（ Paul扮演)），是她堂妹（女2号，典型的泰剧中的坏女人角色）的男朋友。她怀疑Siwa的父亲和她阿姨一起陷害了她父母。描述了解放前粮荒时期的百态人生。贪官当道，奸商囤积居奇，百姓无粮可吃，怨声载道。李颖扮演的凤娇出身风尘，被穷铁匠从妓院赎出从良，但跟着铁匠吃不好穿不暖，最擅长的就是偷吃。在该剧中，李颖扮演的凤娇极为贪吃，几乎每次出场都背着铁匠兄弟在偷吃东西。从偷吃鸡蛋到偷吃小米饭、咸鱼、烧鸡，每次都狼狈不堪，而演惯了高贵女性的李颖也放下身段，每次都演绎的惟妙惟肖，实在是令人钦佩。秦淼跳下车，嬉笑着拉住小葱，要她在这吃晌午饭，下大雪，又没有什么要紧事，不是正好玩儿的时候么。北京知青梅雁，在山西某个中学做着数学老师，她不但独自带着6岁的女孩梅阿娜，而且这孩子还来路不明，没有人知道她的背景，对她的猜测和不好的传言非常多……同为知青的毛毛老师一直深深爱着梅雁，由于他已结婚，只好将这份情感深深地埋在心里，但他经常照顾梅雁和阿娜，这一切却惹来了毛毛媳妇的疾恨，和别的人的猜疑，由于梅雁独身一人，又长得漂亮，学校校长对她垂涎三尺，经常把她叫到办公室，动手动脚，进行性骚扰，但都被梅雁推脱……6.
