If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.该剧讲述两个黑道杀手在黑道组织当中是相互竞争的关系，其中一个被追杀之后成为警方线人又返回黑帮做卧底，另外一个想要脱离组织也被追杀，在此时警方派出了美丽女干探作卧底，最后几位合作和黑帮对决...上世纪初的1903年，大清帝国驻法公使裕庚任期已满，准备携夫人和两个宝贝女儿德龄、容龄回国。长女德玲，精通法语、德语和日语，青春逼人，秀外慧中，高华博学；次女荣龄，美丽单纯，聪明伶俐，是美国著名现代舞蹈家邓肯的入室弟子。裕庚鼓励德龄，在慈禧已经宣布实行新政的时刻回国，是报效国家的良机，德龄也充满了报国的激情，尽管多年居住在海外，祖国的种种已经陌生，但她仍然从心底里爱着这个古老而优秀的国家，她期望自己的所见所闻所学，能够对自己的祖国有所裨益。这天，德龄意外地发现，父亲在临行前和一位不寻常的客人进行了坦率的对话，而这位客人竟是朝廷在四处通缉的孙中山！裕庚欣赏孙中山，因为孙中山和他一样，有一颗赤子之心，德龄由此也对"爱国"有了崭新的认识　　一名拥有隐形能力的少年被一个不入流却又想称霸附近街区的混混拖下水，并结识了一位神秘的艺术生。6 G # q7 B u + S (m不然……将军以为呢？张良佯作外强中干，倒是更有几分此地无银三百两的意思。Next, we will enter the code writing phase of the state mode. First, we will define three state classes, namely offLightState, WeakLightState and strongLightState. All three classes have a prototype method buttonWasPressed, which represents the behavior that will occur when the button is pressed in their respective states. The code is as follows:
