据说，每隔五六年，就曝出站票出现。真爱也许在我们心中不再永恒，但是我们相信这样的爱情存在于天堂……This is a place where the construction of a new socialist countryside is quite effective. Because residents have more contacts with the outside world and more channels to obtain information, the ideological struggle is relatively open, so our work is relatively simple, the villagers are very concerned about state affairs, and many things do not need us to say they understand, even understand more and more comprehensive than us. This makes us basically have nothing to do. In spite of this, everyone feels happy. After all, the purpose of our visit is to let our farmers know about some national policies and forms. Since everyone knows that we have also ended up at leisure, we can free up more time to help those villagers who need help, and we have also improved our work efficiency. The villagers are very enthusiastic, Because I am a rural child myself, Therefore, I am used to everything with everyone in the countryside. Happy days always pass quickly. The seven-day "three rural areas" will soon pass and we will go back. In these short days, we have established deep feelings with our villagers' friends. When we leave, everyone is very reluctant to give up and promises to come often in the future.卖莱仔因铜（王祖蓝 饰）貌不惊人，却有一副好歌喉，渴望有朝一日一曲成名。经过內心反复挣扎，参加了歌唱比赛，最终因相貌丑陋遭人白眼，从此诸事不顺。一天，因铜偶遇美女杨仙嬅（苟芸慧 饰），杨并未因他的丑陋离开他，反而对他坦诚相见，因铜大受感动，对其心生爱意。死党蔡卓严（林子善 饰）有意成全，怂恿因铜大胆示爱，伹生性不善言辞的他在仙嬅问他喜欢自己什么时，他竟张口结舌，说了一些很浮浅的话，致仙嬅误以为他是个只重外表的庸俗男人，转身离他而去。深受打击的因铜误食神奇朱古力，摇身一变成为俊男力信（黄宗泽 饰），伹此药二十四小时后失效，他将变回原形，所以，他的愿望必须在药力失效前完成，好戏开始了……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).
