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.出身于纪律世家的罗耀华（陈豪饰）自小就立志投身警界，但是母亲并不希望他重蹈亡父覆辙，更希望他能当一名普通的中学老师。如母亲所愿，耀华成为九龙城区一所三流中学“林天光纪念中学”的任教老师。横行霸道的校园四大恶人K4设局陷害耀华，耀华愤然辞职，决定一圆他的警察梦。然而天意弄人，刚刚加入警队的耀华，竟被派回原校当卧底，调查校园黑帮毒品事件。学校新来的教师何妙雪（杨怡饰）希望引导学生们重回正轨，她的执着与真心也深深打动了耀华。然而为了破案，耀华不得已假意追求外表冷酷的保龄球教练古嘉岚（钟嘉欣饰），而年青有为的督察程文力（吴卓羲饰）也对妙雪展开追求。Plant name: Rhamnus purshiana杨长帆斩钉截铁说道，让家人失望了。　　三声炮响，轰开了山海关大门，从此大清朝建都北京……红椒骂狗没眼色，山芋骂笨狗，黄豆则恨恨地指着一条大黑狗道：都说会咬人的狗不叫。海天集团董事长石磊是精明能干的商人，同时也是极富爱心的社会公益人士。在一次度假途中，他邂逅了女董事长沈心瑷，两人一见如故。沈心瑷的未婚夫在结婚前夕死于车祸，沈心瑷想要完成他修建福利院的夙愿。由于商业操作的失误，骏豪集团陷入了空前的财务危机，此时石磊向沈心瑷伸出援助之手，两人在的不断接触中，产生了爱情。然而，就在沈心瑷感觉幸福正靠近自己的时候，却意外发现了石磊还怀有更大的商业目的，她崩溃了，选择了离开。石磊没有想到，他已经离不开沈心瑷。一年后，在他们初次相遇的雪地里，石磊静静地坐在那里，沈心瑷来了，看着憔悴的石磊和美丽的、温馨的福利院，沈心瑷相信了石磊为自己所做的一切。衬着孩子们的笑脸，沈心瑷披上了婚纱。
