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.我爱的人，我绝不会让你受到一点委屈。罗城某夜，刑警大队突然接到报警电话，有一个小区发生枪案。值班探长大刘和警员孟津赴现场，发现却是个杀狗案。看到别人都在忙大案，立功心切的年轻警官孟津感觉很委屈，但大刘说服孟津对该案进行详细查访。出发之前，大刘的儿子被人在校外打伤住院，大刘却没有时间去看孩子。雪上加霜的是，孟津的女友要求孟津调离刑警岗位，否则就分手。孟津向女友表示了抱歉，女友含泪离去。此时，市中心医院又发生持枪抢劫案。专案组对弹道进行了分析，大刘等人再一次发现“杀狗枪”的踪迹。医院抢劫案线索渐渐集中在了李成和身上，专案组通过上级在物力财力上的支持，运用科学技术手段、大量排查线索等方式对案件侦破有了新的进展。通过努力专案组进一步掌握了案犯情况，开始对重点地区加强警戒力量，最后将罪犯丁三等抓获。罗城恢复了往日的平静。说笑一会，小葱和秦淼便往后边去准备晚饭。针对不断变化的忠诚，不安的联盟和敌对古代的背景下，共和国和分离主义之间的冲突斜升，从而为达斯西迪厄斯的最终背叛反对绝地行为。在这些不确定的时代，一些该部队的光明与黑暗两面的最深的奥秘被揭示为一个勇敢的克隆人士兵揭露了一个令人震惊的阴谋。天行者阿纳金的关系最密切的是测试它的极限，尤达大师，使这一发现可能会永远改变银河系的力量平衡Tan Weiwei
