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).编自同名漫画《异姓兄弟和平共处法则》，讲述外表高冷却内心闷骚的兄长与呆萌又中二的异性弟弟两人之间互坑互助的日常，攻守高下立现！脑洞新奇绝对让你看得停不下来，他们到底会擦出什么样的火花呢？　　至此，卡斯特的意识中永远烙上了惩罚的字样，他身着战服，从头到脚都武装起来，其明显标志就是展现在黑衣胸前的那个巨大的白色骷髅头像。在接下来的日子里，他便开始寻找并制裁那些他认为参与杀害他妻儿的相关歹徒。在多次直捣敌营，让罪犯横尸一片后，新闻媒体开始把替天行道、执行黑暗公正的他尊称为惩罚者。到底要不要去探查呢？至此，黎章才真正感觉此次行动的艰难和渺茫：虽然有简易地图，但他们反插入敌后，对这里的地形并不熟悉，也不清楚敌军各营寨确切位置，只知道与靖军相对，自眉山西北至东南一线，分别驻扎了南雀国左将军、南灵王、右将军三路人马。一开口，声音就跟耳语似的，方记起嗓子不能话这回事。Article 18 Liability between Ships　　情报所得，恐怖组织头目食客(甘国亮饰)从北韩手上偷走了大量生化毒液，动机不明，但份量足以毒杀整个香港。AT F反恐怖部队总督察马立(周华健饰)茫无头绪，手上只馀十天时间，和一个失忆的恐怖组织成员多特(吴彦祖饰)。他决定利用多特与食客的特殊关系，在心理学家Shirley(陈冲饰)协助下，为多特洗脑，替他虚构了一个身份：被警方派往食客身边的卧底，任务是揭穿食客的行动目的。
