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.

Weightlifters are in the most full and exciting state of physical strength during the competition. After warming up for half an hour and an hour in the back court, they also lifted more than a dozen or 20 handfuls, which is full of physical strength. However, our amateur training generally lasts for a long time and has a high movement density. Even if we are not used to it or like it, it is necessary to wear a belt after the physical fitness starts to decline in the later period. Don't look after the house and break the world record without you, we don't need this amateur level, don't think so! Also don't think: I squat 150 naked and you squat 160 with your belt tied to your knees, so I think I am actually better than you!
科幻片《回到未来》那款可以穿越时空的跑车现实生活中曾批量生产过，但公司还没撑到电影上映就破产了。公司的创始人叫约翰·德罗宁，这个英国人曾被誉为史上最大胆的汽车商人，也可能是史上最大的汽车骗子。 近日一部描述他的纪录片《创造约翰德罗宁》发布首款预告（时光网独家听译中字），《碟中谍6》男星，也就是经常在电视节目中模仿川普的亚历克·鲍德温扮演德罗宁本尊，《死侍》女星莫瑞娜·巴卡琳扮演德罗宁的超模妻子。 《创造约翰德罗宁》不是一部单纯的纪录片，里面既有原型约翰·德罗宁、子女、同事等人的访谈、新闻资料，也有扮演他的亚历克·鲍德温的“场景重现”画面，甚至有亚历克·鲍德温在片场间隙的采访。算是纪录片+剧情片奇妙混合，将于今年6月7日在美国部分影院上映。 德罗宁是一家已经消失的美国汽车制造厂，由汽车业高级主管，英国人约翰·德罗宁于1975年创立。它以生产与众不同具有鸥翼车门和不锈钢车体的德罗宁DMC-12汽车闻名于世。 德罗宁跑车成名于在世界各地广受欢迎的《回到未来》电影，影片1985年上映，但德罗宁公司1982年就破产了。电影中德罗宁DMC-12跑车被古怪的科学家埃米特·L·布朗博士改装成时间旅行机器，其形象成为普遍的大众回忆。 由于公司破产，不再有新车出厂，DMC-12反而成为珍藏品。但直到今日，大量的DMC-12依然还在使用当中。一般估计，生产约9000辆的DMC-12中有6500辆仍在使用，许多由车主、爱好者形成的社团与俱乐部依然十分活跃，甚至成为一种特殊的文化。
