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.在最后一集中，南将饰演拥有地下偶像容颜的女高中生有村美笑。美笑一个人作词作曲，想追求自己真正喜欢的音乐。偶像的活动和将来的事等，烦恼的时候看「三坪房间的钢琴师」的视频被鼓励，不过，有一天，美笑的评语，意外地被回复……这样的展开。五季会继续讲述国务部的故事，因为她还得继续工作。不过一旦竞选开始了，我们便会推进整个过程。我们非常想拍这个过程，已经开始做好调查研究了，接下来会讲述她在竞选途中所发现的事。依望一个人带着两个孩子生活在香港，丈夫志明独自一人在北京的一家国际公司工作。突然一天，依望接到水谣从北京打来的电话，告诉了她一个关于丈夫的秘密。依望当机立断扔掉工作带上孩子来了北京。志明的变化让她如坠深渊，她从来都没有想过跟自己恩爱情深的丈夫会对她说，他不爱她了。此后的日日夜夜，依望始终排解不掉她心中的痛苦和对志明一往情深的爱，她为爱而痛苦着，又在痛苦中爱着，她在爱中真正了解了志明和玲红之间所有的一切。志明在与依望长期两地分居的寂寞中，结识了来北京打工的女孩玲红，这是一对不该产生爱情的人，错爱使他们两人平添了极度的痛苦和自责，他们悬崖勒马结束了刚刚开始的关系，道德的责问更多来自于他们自己的内心深处，这是一个关于道德回归和感情修复的故事，然而却始终令人难以释怀。效丹和仇峰是大学的同学，仇峰来西北自农村，效丹是大学教授的女儿，虽然家庭不同，性格迥然，他们却是一对十分平等的夫妻，他们之间的关系既是夫妻又如同朋友，情同手足，互不设防，他们之间无话不说，赤诚相待。然而，仇峰终于还是对效丹隐瞒了一件-Please follow the friendly instructions of the installation package and restart immediately to avoid unexpected and strange problems.世代研究医术的神木族少年木星尘，救下误闯领地的医药世家之女叶云裳，为逃避皇族内斗而随她一起来到民国乱世，却遇上罕见瘟疫，木星尘凭借青囊术拯救了众生和本族，经历各类诱惑与爱情的考验，最终成为一代医尊，最后他放弃王位，和爱人叶云裳云游人间，济世众生。"Yes, This is 20 minutes, It is also for this reason, Alas, these 20 minutes, I felt longer than two years, Without artillery support, There have been many "halts" in the positions.
