The sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.与此同时，在USNA的STARS基地，一名少女正准备前往第一高校展开潜入调查。故事描述僵尸病毒已经侵袭美国三年时间，这个国家已经彻底成为僵尸的天下。一个由凡人英雄组成的团队必须护送僵尸危机中唯一一名幸存者从纽约前往加州——那里保留着美国唯一能正常运转的病毒实验室，如果能得到这名幸存者的血样，说不定他们能研制出抗病毒疫苗。虽然这名幸存者携带的抗体是人类生存下去的最后希望，但他却隐藏了一个足以毁灭一切的黑暗秘密。无论如何，这个庶民团队还是像「魔戒远征军」一样从纽约启程了，在抵达3000英里外的目的地之前，他们必须横跨遍布僵尸的美洲大陆。在这个后末日时代，他们要面对的危险还远不止吃人的僵尸这么简单。还差几份，但这些也足够说明其中的蹊跷了。Click "Close Block Editor" and click "Yes" in the pop-up dialog box to exit the "Block Editor".故事围绕法医陈学明与督察伍品瑜，一个笃信超自然现象，另一个则是怀疑论者，两人联合办案，从一具具死状离奇的尸体中，探究超自然的现象。陈学明更亲身经历超自然现象，他的女友意外而死，肚子内四个月的孩子竟被神秘“掳走”…理方式会以科学理论作基础，不玩弄迷信、鬼怪，以理性、科学验证、实事求是的态度带领观众进入各种惊悚迷离的世界中。10集的故事以陈之财和李锦梅贯穿，每个故事有不同主角。下午大雾消散，傍晚还看见炊烟和火光。
