故事讲述在有中世纪欧洲风格的异世界古都阿伊特力亚，城内流传着一个秘密情报，就是在某小巷中有一间非常有特色的居酒屋「阿信」，那里的食物是其它地方都吃不到的极品美味，而且很便宜，于是懒惰的卫兵、任性的千金、严格的包税人等齐齐前往，被关东煮、炸物、海鲜盖饭等美食俘虏，其实这只是一间不知为何连接到异世界的平凡日本居酒屋…..上岸以来，胡宗宪对他没有任何限制，除谈判商议外，想来便来，想走就走，去哪里都可以，汪直甚至有两次回到舟山岑港上了自家的船，胡宗宪都没有任何举动。属于鉴识科警犬系的警官，将挑战这个故事的主人公青叶一平（池松壮亮饰）和他的搭档·警犬奥利弗接二连三发生的不可思议事件，但各种各样的想法纷至沓来。《马上回来》：一次车祸夺走了玛莎（海莉·阿特维尔 Hayley Atwell 饰）的男友艾什（多姆纳尔·格利森 Domhnall Gleeson 饰）的生命。在朋友的推荐下，玛莎利用艾什在社交网络上留下的信息塑造了一个具有人工智能的假艾什。刚开始玛莎只能通过手机听到合成的艾什的声音，不久之后，那个声音告诉玛莎，有一个方法可以让艾什“真正”的回到她的身边。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).……郦食其在来到江东短短数日之后，便启程离开，一如到来时迎接的那样，欢送还是相当的隆重的。If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.
