In order to use SYN? Cookies to calculate the SYN-ACK serial number (that is, SYN? Cookies), the host must first combine some local password bits, a data structure including IP address and TCP port number, SYN initial sequence number, and some index data identifying the password bits. An MD5 digest is generated on top of all the above bytes, and then some bits are truncated from the hash value to put it into the SYN-ACK sequence number. Since the size of the sequence number is about a quarter of the total hash value, this truncation is necessary, but usually at least 3 bytes of hash bits are used for verification, which means that there are still nearly 2 24 possibilities to guess and verify cookies without knowing the password bits. In order to send out the hash value, some bits of cookies will reduce the upper limit value of MSS (Maximum Segment Length) contained in SYN and affect the index bits that identify the native password bits in the hash value.Tmall 618 's victory in the first battle gave Wang Bo great confidence. He said that in the next three years, he would slow down the speed of opening stores and embrace new retail in an all-round way, "from horizontal expansion to vertical expansion", that is, to increase the overall turnover of the company by increasing the performance of single stores.On one occasion, the chief contractor of the project had a conflict with the boss of the company and sent thugs to the construction site to prevent the construction.
