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.　　Pierce Brosnan饰演Eli，是McCullough家族如神一般存在的元老。他小的时候曾被绑架，在印第安人的科曼奇族部落被抚养长大，因此他也把科曼奇族 残暴的世界观用在了他的商业事务中。他出生在得克萨斯州宣布独立成为共和国的那一天，所以又被人叫做“德州长子”；可以说他是野性西部的“遗物”，不满德州不可阻挡的被驯化的过程，同时也对自己遗产的未来忧心忡忡。故事发生在202X年。日本被深深的闭塞感所包围，被世界打上了夕阳国的烙印。为了打破这种没有出口的局面，首相鹫田（柄本明饰）启动了一个项目。通过人工智能从全国选拔领导人，让他们承担起治理颓废城市的重任。年轻人不能担当政治的理由，一直被认为是“经验”少。人工智能拥有一个人根本无法得到的“经验”的庞大数据。也就是说，人工智能可以补充很多“经验”。 AI选择的首相是17岁的少年真木亚兰（神尾枫珠饰），年纪尚轻，但追求理想社会。其他成员也都是20岁左右的年轻人。真木和同伴一起运用AI推进改革，使濒临衰退的地方城市，作为实验城市重生。@哦撸马（阿点）　　杨白对夏博文总是淡淡的，晚上过夫妻生活也总是关灯，夏博文从未看过她光着的身体，很是自卑。久而久之造成了生理障碍，无法过一个正常男人的生活……影片中偶然相遇的一对男女,在釜山度过了率真淡泊的24小时.以美丽的海滨城市釜山为背景,全面描述了男女主人公从相遇到相恋再到分手的爱情故事.Article 4 The labor and social security administrative department of the local people's government at or above the county level shall be responsible for supervising and inspecting the implementation of these Provisions by the employing units within their respective administrative areas.六集诗选剧《零异频道：蜡烛湾 Channel Zero: Candle Cove》在10月11日首播，由Kris Straub所「着」的Creepypasta（转贴恐怖故事﹑都市传说）改篇，这剧讲述男主对一个80年代的神秘儿童节目十分偏执，因为他相信该节目引发了一连串的梦 魇及死亡事件。蜡烛湾是现实的都市传说，在当时一个美国论坛有人问一部诡异的儿童节目，名为《蜡烛湾 Candle Cove》，然后一群人指他们对这节目有记忆，而且还指发生了各种奇怪事件，但后来Kris Straub出来指这节目其实是他捏造的，然而不少人皆表示不相信，并质疑他是想隐瞒该节目的存在。
