　　经过蓝波和尚恩的不懈努力，威尔渐渐敞开心胸，而好友查克的一席话，更是让他豁然开朗。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.1944年日本悍然发动了蓄谋已久的豫湘桂战役，战况已危及陪都重庆和我西南大后方的安全。国军桂林行营，中华国民革命军副总参谋长杜长官召集干将们部署美国特使华莱士来桂林商讨中美联合作战协作方案的安保工作，上校情报官黎明江临危授命负责特使在桂的安全。美丽的桂林，天下之绝景，曾经在抗战的烈火中如何被倭寇变成了人间地狱？战争中的人们又各自演绎着怎样的聚散无常？(12.27 update)这是一个远古时代恐龙家族如何生存的故事，其间反映了恐龙间的亲情和友情，并通过森林中的历险再现了它们的勇敢和诚实精神，此片给我们展现了一幅远古时期生物的进化图卷。2.
