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.那汉子也低下头，讪讪地笑了，目光阴沉。Ma Jinyu: In a muddle-headed way.然而，若是过于执着，陷入红尘纠纷，那住持和众人出家所为何来？法惠就张大了嘴巴。他不按官场牌理出牌，不畏黑势力，追踪千万巨款海外洗钱，前书记被杀事件。那个人是一手提拔自己的人，可那个人卷进了一个黑暗的漩涡，那个人最终成了一切罪恶的幕后。省级机关的外长司马田，作为后备干部对象下派到某市，担任“签约书记”。他不按官场牌理出牌，引起了市机关、社会各界的震荡，尤其是他不畏上面，不畏地方黑势力，触犯了当地乃至更大一些的头面人物的利益后，他的仕途便走进了一条狭窄的胡同。他追踪千万巨款海外洗钱，追查前书记被杀事件。承受了地方势力张麟山与“高老师”设计的拉拢、棒杀、绑架、杀戮等等险恶怪招。他发现，提拔他的老领导庞副书记是洗巨款、造罪恶、杀戮的幕后，他几乎陷入绝境。当庞副书记提出让他放一马时说，你是我的人，你把我交待了，你也完蛋，司马田真的犹豫了，最终，他流着泪做出了艰难的抉择。然后拍拍手掌，站在场地边缘端详道：好了。(3) When all the Concrete Event Handlers are registered, the application will call the handle_events method to start the event loop of the Initiation Dispatcher. This is where the Initiation Dispatcher merges the handles of each registered Concrete Event Handler and synchronizes the occurrence of blocked waiting events using the Synchronous Event Demultiplexer. For example, the TCP protocol layer uses the select synchronization event splitter operation to wait for the data sent by the client to reach the connected socket handler.
