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.Q: What do you think is the key to winning the competition?三田园薰虽然身为体格壮硕的男性，从事的却偏偏是女性雇员居多的家政行业。三田园薰身手矫健动作利落，精通各类洒扫技巧，更为不一般的是，他似乎更加擅长的，是找出雇主家庭中的黑暗面和弱点，对他们伤痕累累的心灵进行修复。除夕之夜，灾难突如其来地发生了，雪崩骤至……400多人惨死冰天雪地的金刚山里，事件迅速惊动了省和中央，白玛市金刚山现场指挥部紧急成立，直升机，救护车，公安武警部队，记者等开向现场…… 雪堆中，方华生家和丹巴家这两个白玛市最大的家族儿女，公安局派进华生黄金公司的卧底，华生黄金公司的会计，暗中追查华生黄金公司内幕的北京记者等不幸遇难……Beware of minor attacks周菡忙问道：那他送到了吗？林聪被问住了，迟疑道：应该是送到了吧。未来某时，一种丑陋凶恶、仿佛来自地狱的怪物肆虐人间，大肆屠杀人类。某小镇在怪物的荼毒下宛如一座死城，生存者战战兢兢，惶恐度日。
