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).看到陈启，夏林连忙说道：老板，《笑傲江湖》的拍摄工作一直很顺利……陈启笑了笑，说道：剧组有你在，我很放心。Deliberate practice does not deny the importance of situation, but in some best sellers, the mainstream methods that have been confirmed by learning science are placed in a humble corner. Tacit knowledge, which is closely related to learning, is ignored. A large number of studies in learning science show that the best way for adults to learn is not to practice alone, but to learn in situations. Effective learning is to enter relevant situations and find one's own "learning community". At the beginning, learners turn around important members and do some peripheral work. With the growth of skills, they enter the core of the learning community circle, gradually do more important work and eventually become experts.杰克船长又回来了，这次，他遇到了更为强大的敌人，传说中的不死人大卫·琼斯，他驾驶着让人恐惧的“飞行荷兰人”号快船，在速度与装备上，没有任何船能够超越它。杰克船长欠下琼斯一个血债，他必须赶在最后时限到来之前，找到破解的方法，否则他会永远背负血债，余生永远成为琼斯的奴隶。
