白凡忽然哈哈大笑。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.Article 36 Signs for Attention谁知路上的守军太过不堪一击，有的甚至直接开城投降，想慢也慢不了。　　特勤第八组是尖刀部队，成员各个身手不凡。在与“血狼”数次交锋中，化解了多次恐怖袭击，但也经历了沉重的流血和牺牲，曾经懵懂无知的女孩们成长起来，成为了真正的特勤战士。直到最终将恶贯满盈的恐怖分子击毙，击溃了国际恐怖组织的阴谋。捍卫了祖国荣誉，守护人民的安康。从板栗等人的惊讶神情中，他知道大靖确实还没有这玩意，便狐疑地看郑氏。
