The picture shows Mr. Sun and his team members communicating with each other.SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.　　Thann，刚从国外搬回泰国上大学的小男生。Thann跟随家人搬到韩国生活了几年，他这一次回来，又遇到了Kavin——他的初恋和唯一一个男友。当Kavin请求Thann跟自己和好的时候，一堆麻烦狗血的事情就发生了，因为此时Kawin已经有女友Irin了。Thann生活在两个世界中，而且尽量不让这两个世界中的自己混淆。但是却还没这么容易结束，因为此时Thann在韩国最要好的朋友Jihun也跟着过来泰国玩了。Kavin以为Jihun会抢走Thann，于是两人都看不惯对方。于是一场狗血的四角恋就发生了。大家也该是时候撇开自己的自私，去承认事实，然后去为这一次的感情做最好的抉择。Ice hockey笑毕，他忙又问挖陷阱是怎么回事。Also in the video: PMDG748, WF ZBAA, Bridge ZUUU没什么意思。
