Nazhi's classmate chased him out: "Give me 50 cents." Li Shanglong thought he heard it wrong: "What?" The classmate said very seriously, "You just played for two minutes and gave me 50 cents."接着，他看着地上那堆金银珠宝，气愤愤地想道：娘说的话就是对，钱这东西，多了就是累赘，还招人惦记。Tutorial File Download: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.般配不是外人说的，而是我们自己说的。机智勇敢的黑猫警长侦破了一个又一个案件，保卫了森林的安全。人物表情刻画得极好，故事情节也特别适合儿童的心理。　　渴望城市生活的山里女人笋妹，不顾青梅竹马文春的劝留,毅然奔向了华丽的都市。而文春却独自在痛苦中挣扎。在时间的冲洗中,菊子踏入了文春的生活，在一次次独处中，他渐渐和菊子产生了感情。几年后,文春做了一村之长，落魄的笋妹回到了山里，因在外面的不轨行为导致了全村的排斥，自杀的想法不断在笋妹脑海里荡漾。几次被文春所救，慢慢地笋妹冲破了世俗的束缚，二人似乎又回到了当年……
