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).重拍将在法国4台播出（或多或少类似于BBC3）。Bloody Harvest: Report to Prince Varanal, who died at the end of his life, and then fly to the bottom of Diablo Castle by Skull Bird, where you can see Prince Varanal and hand in the task.1800年前，中国流传着一种古老的拳法——北斗之拳。该拳法以人体内部穴道为打击对象，由内至外达到毁灭对手的目的。为了防止武功外泄，北斗之拳向来一子单传，只有真正的强者才可成为拳法的继承人。至琉泉一辈，他收养了三个养子，分别是拉奥、托奇和健四郎，北斗之拳终于迎来1800年来最强的时代。与此同时，地球上愚蠢的统治者发动无休止的战争，最终导致人类文明毁灭，世界堕落到暴力至上的时代。在乱世之中，三兄弟以不同的方式展开了波澜壮阔的人生……该剧是2016年日剧《卖房子的女人》的续集，讲述天才不动产从业者三轩家万智顺利地把合适的房子卖给顾客的故事。3.
