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.曾受过情伤而封闭了自己内心的富商佟俊铭认识了温暖善良的女主播梁馨之后，生活发生了变化。佟俊铭和梁馨因为意外结缘，梁馨一直以为佟俊铭是一名叫做“童杰”的厨师，她为了应付逼婚的父母，让“童杰”假扮自己的男朋友；而佟俊铭因为种种原因，没有拆穿这个谎言。梁馨因一次直播意外，从一档当红节目上被撤了下来，去主持一档无人问津的节目。但梁馨没有放弃自己的主播梦想，不管是什么样的节目，她都想做到最好，在“童杰”的帮助下，她的新节目有了起色，两人的感情也渐渐升温。当“童杰”以佟俊铭的身份站在梁馨面前时，梁馨有些无措；而曾经因为封闭了自己内心、变得冷漠的佟俊铭再次敞开了心扉，重新成为一个“暖男”。两人携手谱写了一出浪漫温暖的都市爱情都跟你说了，这是计谋。　阿峰（吴彦祖饰），小虎（杨佑宁饰）和大刚（刘烨饰）是在乡下从小一起长大的好兄弟，好朋友。大刚为了出人头地的梦想，说服他们，一起来到了传说中黄金遍地的上海，准备大干一场。到了上海一段时间后，小虎和阿峰来到了天堂口歌舞厅，在那里遇到了美丽的歌女露露（舒淇饰），还有当时在上海声名显赫的实力人物，也就是天堂口的主人洪哥（孙红雷饰）。在歌舞厅的侧面路口，阿峰偶遇了受伤倒地的马克（张震饰），并把他带回家救治。从此，这几个好朋友的人生围绕着醉生梦死的天堂口歌舞厅开始发生变化……
