先前紫茄还小，自然没啥事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.Public Handler getHandler () {Tashi: I was very introverted, and then I saw the woman and thought it was.以中国工农红军第一、二、四方面军甘肃会宁会师，长征取得伟大胜利，中国革命从挫折走向胜利的伟大转折，从此，开始了由国内革命战争向抗日民族解放战争的转变，中国革命进入了一个崭新的历史阶段为背景。再现了红军三大主力胜利会师的光辉时刻，生动塑造红军指战员在铁血征程中的英勇壮举。
