为了粉碎日军在山东的侵略阴谋，八路军组建了以营长黄鸣锋为队长的利剑特遣队，就在黄鸣锋执行任务时，找到了失踪的苏五巧，更有兰如剑、穆雪飞和柳迎春加入，利剑特遣队又壮大了起来。他们炸掉了日军的武器库，摧毁了日军一次又一次对共产党的武装围剿，炸沉了运送实验化学制剂的太和号货船。就在大家为完成任务松了口气的时候，黄鸣锋接到了上级总部传来的消息，日本军官杉木已将一批实验化学试剂运走，估计三天后将运抵前线。黄鸣锋立即率队员出发，他们劫持了一辆日军卡车，日夜兼程追赶杉木。黄鸣锋最终以自己的生命为代价，完成了任务。只有青木不在，他带着马小六去集市了。讲述了少女乔可星进入世界一流的偶像学校——菲梦学院，与队友宋诗语、杨松儿结成组合美乐蒂，共同训练，历经考验，共同成长，最终实现梦想的故事。通过艰苦的体能测试、意外频出的广告拍摄、竞争激烈的最终选拔测试等种种难关之后，美乐蒂逐渐成长为可以独当一面的偶像组合，正式向真正的偶像出发。矮几上点着一盏油灯，如豆的灯火看起来也是无精打采。Since its basic attack principle is backlog overflow that depends on the end host connection socket, an obvious end host-based solution is to increase the backlog queue size, and this method has been widely used in most servers. Increasing the backlog queue is usually done by modifying the application's listen () function call and an operating system kernel parameter SOMAXCONN, which is used to set the upper limit of backlog that an application can receive. This method itself cannot be completely considered as an effective method to resist SYN flooding, even in some operating systems that can effectively support super large backlog queue allocation, because attackers can arbitrarily generate datagrams much larger than the backlog supported by their operating systems.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.他喃喃道：‘愿得一心人，白首不相离。
