A. Ear auscultation tube examination;“在我们互相爱慕之前！！”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.在他眼里，杨长帆还犯了一个巨大的愚蠢的错误。天启：多谢支持。外表帅气、作风轻浮的马桶垫设计师伢叔和妻子离婚后，与女儿小敏一起生活。某天，在一次日常的厕所蹲坑中伢叔竟然被马桶吸了进去，稀里糊涂地成为了超级英雄，被赋予了从外星人手中拯救地球的重任。而他成为超级英雄的代价就是从原本英俊帅气的型男变成肥胖油腻的大叔。就这样，伢叔开始了与众多非典型外星人鸡飞狗跳的日常……1
