At present, what methods do we take to solve the attack? The first method shortens the waiting time and deletes the illegal request data packets waiting in the waiting queue as soon as possible. The second method is that the first handshake message is not put into the waiting queue. We return a 32-bit unsigned integer to the client as the Seq of the second handshake. The integer is obtained by adding a serial number of the server to the parameters requested by the user (including the requested address, port, etc.). If it is a normal user, it adds 1 as ACK after receiving this integer and returns it to the server. After receiving the data, the server subtracts 1 from this ACK and then performs inverse operation to obtain various parameters. Finally, the data sent out are compared. If they are completely consistent, it means that it is an effective response and stored in the corresponding data structure, otherwise it is not. Through this method, illegal requests cannot occupy system resources.RST Flood　　六月十七日，京城发生兵变，燕王朱棣率军攻陷都城，继承了帝位。铁铉带着年仅七岁的逊太子朱文奎出逃，被朱棣派的大批高手追捕。万般无奈之下，铁铉夫妇与谢晓峰合演了一场苦肉计，铁铉把太子的服装套在自己亲生儿子的身上，让谢晓峰杀死自己和儿子，以使敌人产生误解就此罢手，不再追捕太子。这幕惨剧被躲在芦苇中不明真相的铁铉之女铁真真看到，她发誓将来要为父母报仇。 　　书签上还有一行清秀俊逸的手写字。乖巧伶俐的红娘与莺莺主仆情深。两人正值花样年华，少女情怀，彼此都希望寻得好归宿。一次花灯盛会，红娘和君瑞分别拾得半边鸳鸯扣。二人寻寻觅觅，却始终缘悭一面。但当红娘对君瑞情根暗种、几乎可以打开缘份大门之时，命运却使缘份落在莺莺手上。相国夫人与莺莺、红娘来到普救寺还神。风雷寨一群山贼闯进寺中，掳劫莺莺，要挟相国大人，情势紧迫，如箭在弦。夫人许下承诺，能救莺莺脱险，莺莺便下嫁于他。适逢于寺内念书的君瑞仗义救人，舍命救出莺莺。莺莺与君瑞经过生死劫难，才子佳人一见钟情。红娘眼见缘份落在二人身上，但仍衷心为他们祝福，更认定君瑞与莺莺才是一对璧人，而自己不过是卑贱的丫环，根本配不上君瑞，因此红娘甘愿为二人牵上红线。因最后一次任务而感到内疚的老兵与好友的遗孀联手渗透进了一个危险的哥本哈根摩托帮。……江南电视台。
