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).If you want to adjust the default values of the above parameters, you can modify them in the registry (the location is the same as SynAttackProtect)Return handler;In the traditional subway construction, collision inspection can only be implemented after the design drawings of various specialties are summarized, which is time-consuming and labor-consuming and affects the project progress. Using BIM technology, collision inspection can be carried out on the pipelines of the building before construction, clearance and pipeline arrangement scheme can be optimized, hard collision can be eliminated and soft collision can be avoided as much as possible, and error loss and rework can be reduced.本片为魔法少女的剧场版，分三部上映，由TV版12话重新编集而成。Another example is that a big sword will have the same effect, but it is worth mentioning that whether the weapon has sufficient contact with the BOSS will also affect the weakness damage. For example, if the same part is completely cut, it will be yellow, while only the tip of the sword will be wiped, and only about half of the damage will be white.待洪水泄得差不多后，林聪便率领早已准备就绪的将士们纷纷下水。
