当然了，其中也有反应快的，只见两个面容姣好，艳光动人的女子上前一步道：奴家赵子儿，奴家管氏，被魏豹强抢入宫，求汉王解救。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.　　Freeform宣布续订《#麻烦一家人# Good Trouble》第二季。陈寻和方茴两个人在大学校园里相识，体验了人生中第一次的怦然心动，也开始了长达十几年的羁绊。在从大学到研究生的青春岁月、从千禧年到非典肆虐的年代记忆中间，他们的情感萌动、升华，最后无奈地结束。他们与好友乔然林嘉茉 赵烨一起，曾经共同为爱情矢志不渝，坚守着心中最初的那份纯真，也曾经一起被命运捉弄，因为不愿放弃而被折磨得遍体鳞伤。在匆匆而过的岁月间，他们顽强地生长成人，却无奈地失去了彼此。这段无法忘怀的记忆，让年过30岁的陈寻释怀了人生中的遗憾，找回了少年时代的勇气，让他决心重头再来，跟随记忆的线索去寻找方茴，去追寻生命中那阳光璀璨的匆匆那年。One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.　　仁宗年间，杨六郎延昭（高雄饰）率领宋军与辽军大战。主帅庞龙（冼灏英饰）妒忌杨家将之功名，用计拖延援兵，导致六郎战死辽境。幸而杨宗保（徐少强饰）得庞烈（吕颂贤饰）之助逃回天波府。
