In addition to solving the port problem of A, the serial number problem also needs to be paid attention to. The serial number corresponds to the sliding window. The fake TCP packet needs to be filled with the serial number. If the value of the serial number is not in the sliding window of B when it is sent to B before A, B will actively discard it. So we need to find the serial number that can fall into the sliding window between AB at that time. This can be solved violently, because the length of a sequence is 32 bits, and the value range is 0-4294967296. If the window size is like 65535 under Windows I caught in the above figure, I only need to divide, and I know that at most I only need to send 65537 (4294967296/65535=65537) packets to have a sequence number fall into the sliding window. The desired value can be calculated quickly by exhaustion on multiple control hosts.想被疗愈的男人As shown in the above figure, the server side provides NTP service. Attacker sends an NTP monlist Request to the server, but its source IP address is not its own IP address, but the IP address of the target. After the server receives the request, it will send a Response message to Target (not Attacker). Since Reponse contains 600 time synchronization records with Server, which is much larger than Request and consists of many messages, amplification is realized.两倭寇见状哪里还敢缠斗，提刀转身便逃。《天若有情2》是导演胡意涓在2006年进行续拍的电视剧，董洁、方中信、孙耀威、六月等人主演的电视剧。讲述了一个艰难的爱情故事，故事最终以完美的结局告终。樊傻儿以少胜多大破日军坦克阵，却被上司剥夺军权，贬为视察员，在去江城路上，险遭暗害，傻儿均使巧计将杀手击败，傻儿在江城经历了许多惊心动魄的事件，消灭了以侯敬堂为首的一伙贪官，令百姓感恩戴德。正众望所归，如日中天之时，傻儿却大发傻气，弃官而走，开始了新的漂泊生涯……
