A fundamental and universal problem closely related to this aspect is related to the use of open DNS parser to launch DDoS attacks against Switzerland, an anti-spam organization. The open parser does not validate the IP address of the sender of the packet before sending back the DNS reply. Therefore, after the attacker deceives the victim's IP address, he can send a large amount of attack traffic to the victim, and the ratio of attack traffic to request traffic reaches 100: 1. DNS amplification attacks such as these have recently been used by hacker activists, blackmailers and blacklisted website hosts with great success.The responsibility chain pattern describes how requests are passed along a chain of objects. It forms objects into a chain, and the sender sends the request to the first receiver of the chain and passes it along the chain until there is an object to process it or until there is no object to process and it remains at the end of the chain.相传“千门”由伏羲氏创立，在历史中不断演化发展，形成各门各派，涵盖赌术、骗局、易容术、催眠术、中国戏法等等，民国时期最为鼎盛。“千门”技艺概不外传，直到门中一少年为报杀父之仇，开始揭秘各中因果，世人才恍然大悟。故事发生在民国时期一个“三不管”的地界，这里三教九流汇集，俨然是一个暗潮汹涌的小江湖。因一场离奇的案件，三个身份各异的年轻人走到一起，开始“组团”破案的历程。此后一桩桩超自然离奇案件接踵而至，各色光怪陆离的江湖奇人悉数登场，隐藏在所有案件背后的神秘力量慢慢浮出水面。本剧取材于真实事件，贴近生活，展示了乡村和谐社会的美好画卷。马向阳，一个毫无农村生活和工作经历的商务局市场科科长，一个领导同事眼中的业务能手“马大能耐”，一个儿子眼中“才疏命薄”的单身爸爸，一纸调令，转眼就成了省重点扶贫对象大槐树村的“第一书记”。从公务员到村官，从城市到农村。马向阳时时处处感受到自己的格格不入。与此同时，马向阳的“前世冤家”蔡丽，因缘巧合地闯进了马向阳的世界。给这个本已焦头烂额的马大能耐又添了几把火。已经快被打压到底的马向阳触底反弹，绝境逢生，以坚韧的耐力给大槐树村创造着一个又一个惊喜。最终，“第一书记”任期将满的马向阳续签了自己的聘任合同，立下誓言，要跟这大槐树下的“农哥们”“农姐们”齐心协力，共同迎接将来的生活。Mystery:
