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).DDoS attacks are divided into three layers: attacker, master and agent, which play different roles in the attacks:成田望（水谷丰）是一名律师，其妻柚子（床岛佳子）则是法官。由于柚子在地方工作，和望几乎一周都见不到一次面。为了解决夫妻分居的问题，许久没有回家的柚子给望看了一份名为“非常勤法官招募”的文件。据柚子说，这是考虑到促进法曹一元化、改变法官律师两立的局面、从整体法律职业的角度以求做出更好的判决，由此而来的制度。望担任“非常勤法官”，也就是说他要一边进行律师执业，同时出任兼职法官。望出任法官的第一份工作是“申请撤去腐叶土案”。翻译家若杉秀人（三浦浩一）家中的庭院里，放置着有异味的腐叶土，野濑志摩子（筒井真理子）等邻居，提出撤去腐叶土的诉求。很快，望展开了调停…因为，板栗肤色黑一些，虽跟小葱眉眼相像，但看起来差得有些远。? When the Win10 system is in use, it is clear that the network cable is connected, but it is impossible to connect to the Internet. What if the Win10 system cannot connect to the Internet with the network cable plugged in? How do you fix it?
