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).
There are also some plants pollinated by insects, which do not bring any benefits to insects, but attract their own pollinators in a similar way of deception. For example, Mei Lan is an example. It set a simple trap to make the drone think it would be a wonderful date. The drone was the first to fly out of the hive in spring, while the female was relatively late. Orchids take advantage of this. Their flowers look very much like female bees, making many drones stay here. Moreover, the flowers of Red Gate Orchid not only look like female bees, but also can emit similar smell to female bees. The hungry drone was easily cheated and tried to mate with the lip of the orchid, so that the drone would stick to two pollen blocks, which were small balls wrapped in pollen. At this time, the pollen would fall off and then stick to the drone. The drone had to leave frustrated after the mating failed. When it was fooled again and stayed on another eyebrow orchid, it helped eyebrow orchid to pollinate.
