这也是聪明反被聪明误。For spoofing attacks, the first thing to consider is to choose the address. For the attack to succeed, the host on the spoofed IP address must not respond to any SYN-ACK packets sent to them. A very simple method that an attacker can use is to disguise only one source IP address, and this IP address will not respond to SYN-ACK packets, perhaps because there is no host on this IP address at all, or because some configuration has been made to the address or network properties of the host. Another option is to disguise many source addresses, and attackers will assume that hosts on some of these disguised addresses will not respond to SYN-ACK packets. To implement this method, you need to recycle the addresses on the list of source IP addresses that the server wants to connect to, or make the same modifications to hosts in a subnet.游荡巴黎的扒手迈克尔·梅森(麦登饰)一日行窃钱夹成功后，不幸卷入中情局调查的惊天罪案。肖恩·布瑞尔(艾尔巴饰)作为案件负责人果断决定，携手梅森在法国国庆日这一天向恶势力展开反攻。　　2016年立项，迪士尼一次性攒了20部作品顾小玉则是一脸惊叹和佩服。　　安宇熙，一名爱好音乐的男生，生活在一个幸福的家庭，爸爸、妈妈，还有一个可爱的妹妹安子熙。安宇熙会经常捉弄妹妹，他把安子熙欺负的哭起来，或者假装生气迫使妹妹隐瞒秘密。突然有一天出现了一个男人自称是安宇熙的生父，安宇熙的身世之谜浮出了水面。 　　同一个城市兄妹二人擦肩而过，再次相见是偶然还是天意？一次选拔活动再次把安宇熙和安子熙的命运联系在一起，他们共同努力，共同进步，安宇熙最终脱颖而出，得到了去一线城市学习发展的机会，妹妹安子熙也希望通过自己的努力将来有一天可以和哥哥再次相聚。
