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.Http://staaldraad.github.io/2017/10/23/msword-field-codes/意外出名的农民歌手万喜，衣锦还乡后被乡亲们选为村长。万喜本想在村里大干一场帮助大伙脱贫致富，没想到乡亲们根本不想改变现状，只想利用他的名气多要点救济款。万喜不愿当个“要饭”村官，他顶住压力大力发展特色农牧业，却遭遇种种困难与挫折。万喜疲于应付，幸好他的初恋杏花帮忙解决了不少难题，这也引起了万喜媳妇梅花的误会。收获季节，农产品滞销，乡亲们责怪万喜无能想换个村长。万喜说服乡亲们让他试用几个月，发誓让大伙挣得比扶贫款多几倍。为了实现对乡亲们的承诺，万喜聘请了女大学生田欣帮助大伙利用互联网卖农产品。在众人的努力下，农产品销售一空。万喜实现了承诺，成为乡亲们认可的村官一番话说得葫芦外婆脸色发白。6.
