他一字一句地说道：我，不会替你死。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.南天中的池賢守和北地中的韓正筆，這兩個山脈的至尊到了高中之後，一樣席捲了兩大山脈的地盤，但是這個時候誰也沒想到鬼怪的出現，他的出現讓整個世界捲進風風雨雨的天下，兩大山脈的崩盤，天下第一的來臨，他是鬼還是人呢…？TCP Flood郑合适抱着鲜花向钟情已久的方美兰求婚，不料婚没求成，反被方美兰的前小叔子曹天风一板儿砖开了瓢。当年，师父方清平“嫌贫爱富”，他明知徒弟郑合适与方美兰相好，愣是棒打鸳鸯逼女儿嫁给了曹家。郑合适一怒之下与方清平断绝师徒关系，并另立门户开办“合适居”，与师傅唱对台戏。恰逢村里计划开发凤凰山旅游，方清平、郑合适师徒二人明刀明枪地展开了竞争，演绎出一场精彩的龙虎斗。无私的郑合适为凤凰村发展所做的努力终于得到了方清平的认可，他开始逐渐转变了对郑合适的态度。师徒二人从对抗到携手，从分歧到统一，最终郑合适如愿收获爱情，师徒冰释前嫌。在他们的牵头带动下，凤凰村旅游项目发展势头喜人，凤凰村精神文明建设收获累累硕果。　　他从没想过，如此极端乖张的做法会将自己和他人带向何方……After returning home, many students asked "what have you gained from the three rural areas". What I want to say is "some things can only be understood after experiencing them. Some gains are not at the end but in the process". At present, we are still not students who have gone out of school. We always have many lofty ideals and aspirations. Just like me, I am a freshman, and I always think that I can make great efforts in those developed cities after graduation, and my heart is higher than the sky. I don't think there is anything wrong with this. I have always classified this idea as my personal desire for advancement. But after this trip to the countryside, I seem to have realized something different. Everyone is diligent, everyone expects themselves to work in prosperous areas and enjoy high treatment, which is understandable. However, those who know how to repay the society and spread their light in poor areas are extremely noble. "Three Supports and One Help" is a very good policy to enable more college students to have such opportunities to shine.
