狠狠的往里顶撞H/第09集/高速云

在这一季里面，杰克·鲍尔（基弗·萨瑟兰 Kiefer Sutherland 饰）戒掉了在第三季中染上的毒瘾，并且离开了CTU而开始为国防部长工作。但是杰克始终摆脱不了与CTU的联系，剧集一开始一场恐怖袭击致使的列车出轨事故使CTU不得不召回杰克进行此事的调查。才深入调查此事没多久，杰克就发现恐怖分子的下一个目标就是国防部长。经过杰克的努力，好不容易解救了被绑架的国防部长，化解了这次危机。原本以为可以松一口气的杰克，却发现刺杀国防部长只是恐怖分子设置的一个扰乱CTU调查的小环节。恐怖分子的真正目的是控制全美国的核电站，通过让核电站超负荷运转引起核泄漏进而威胁全美国，危机这才真正上演……　　在另一边，糖果的网络主播朋友齐淼偶遇恶犬袭人，挺身与恶犬搏斗，救下行人，令人意想不到的是，整个过程被人拍下，经过恶意剪辑后，竟以“虐狗”为标题发送到网上，齐淼一时间陷入舆论漩涡，百口莫辩。"Where is your young friend?" I asked.SYN attack is a kind of DOS attack. 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.只当这是一个探查的据点，其实防守很严密。After the desturctor () event is triggered (isPersist! ==true), empty that event object property.获2002年斯图加特国际动画电影节最佳长篇奖，获2001年日本文化厅文化厅MEDIA艺术祭动画大赏。
