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).本作品主角三桥廉是个希望自己成为所属球队王牌投手的少年，在中学时期被认为靠着爷爷是三星学园经营者的关系，才能成为该校棒球部的王牌投手，因此队友对三桥有着极大的反感，结果不但造成其在中学三年一胜难求，更导致他懦弱、自卑又孤僻的个性，甚至一度考虑放弃棒球。细巧的下巴一扬，一副奸计得逞的神情，心下更加怀疑了。四位来自现代、各有专才的美女，误打误撞地卷入了一桩桩悬念迭生的古代大案，她们各展所学，于凶险离奇的环境中联手侦破了：许愿树下靺鞨使节被杀案、天香楼县令公子命案、上下棋舍生死迷局案、祈家六指怪人案、抢夺金矿引发的复仇案、金船赤水帮派火并案、澈水镇寻宝连环血案，这七桩惊世奇案温兆伦。　　Ramnam（Green Ausadaporn 饰演）是有几分姿色却出身贫寒的妙龄少女，一直对自己卑微的出身耿耿于怀。她下定决心，要尽一切努力使自己的生活变得更好，直到没有人侮辱嘲笑她的出身。Ramnam秘密地爱着自己的养父——Lue（Peter饰演），而Lue已经是有妇之夫，有一位完美的妻子Nampink（nune woranuch 饰演）。因此，Ramnam试图煽动Lue和其他女人调情。Nampink一直很相信Ramnam，却不知道这是Ramnam想要除掉自己取而代之成为Lue妻子的邪恶计划。当Lue真的开始和Ramnam在一起时，他的生活开始走下坡路。由于Nampink和他离婚，Lue的工作因为他私生活的八卦产生了很多问题。而Lue从来不对外承认Ramnam的身份，这让Ramnam感到非常难过。Nampink则在她的朋友Ratee的帮助下开始了她的新生活，并与Ratee的哥哥Umpon建立了良好的友谊剧情介绍
