When the SYN gateway receives the SYN packet from the client, it directly forwards it to the server. After receiving the SYN/ACK packet from the server, the SYN gateway forwards the packet to the client and sends the ACK confirmation packet to the server in the name of the client. At this time, the server enters the connected state from the semi-connected state. When the client confirms the arrival of the packet, it forwards if there is data, otherwise it discards it. In fact, the server has a connection queue in addition to maintaining the semi-connection queue. If SYN attack occurs, the number of connection queues will increase, but the number of connections that the general server can withstand is much larger than the number of semi-connections, so this method can effectively reduce the attack on the server.公元前202年，西楚霸王项羽在乌江边自刎，让无数人扼腕叹息。2000年后的今天，一个消失了所有记忆的男子走在街上，救了一位被一黑衣人追赶的女子虞心。虞心为了感谢，便收留这个男子，给他取名为龙探。虞心、龙探以及一个热衷于探案的富家公子哥杜渊一起成立了“龙探社”。龙虞杜三人乐于助人的精神帮助陌生人完成了大大小小的请求然而他们不知道的是他们三人正悄悄的被卷入一场跨国走私文物的漩涡之中，等待他们三人的是更加危险艰难的处境。面对重重危险，龙虞杜三人挺身而出，在经历过各种考验之后他们更加懂得了友情、亲情、爱情的珍贵。板栗赞道：我爹也没说错，这个尤其要紧。Deployment/retraction landing gear G G only works if the landing gear of the current aircraft is retractable.这是刚才出来的时候，一个军士递给他的。因此他们见刺杀得手，援兵已到，便离开抢过汉王侍卫的马匹奔逃。您老远来了，还没有吃饭了，我们先找一个地方去吃饭……餐馆也不是说话的地方，现在就带我去你住的地方。
