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.1941年年初的一个夜晚，由日本派到中国的秘密信使在上海的南京路被一伙身份不明的人所劫杀。他所带来的重要秘密信件被劫走。原来，这一伙身份不明的人是重庆国民政府中情局所训练出来的秘密特工——黑玫瑰行动小组。这个小组的组长是年轻漂亮的黎紫涵。黎紫涵从劫来的信件中只发现了5个字——“富士山的雪”，她断定这是日寇的一次重大的秘密军事行动。日本信使在南京路被杀的事件在沪上引起轩然大波。警察局高级探长郝瀚介入了本案的调查。日军驻沪最高司令松本严令特务机关的机关长熊井也要侦破此案，消灭黑玫瑰。松本司令在官邸要会见德国驻上海总领事汉斯。黎紫菡决定：夜闯松本官邸，劫取“富士山的雪”计划书。熊井为了避免“富士山的雪”被黑玫瑰窃取，决定动用王牌间谍“樱花皇后”并找到极司菲尔路76号里的大汉奸李逸群出山共同消灭黑玫瑰。经过调查，“富士山的雪”就是法西斯德国把刚刚生产出来的大规模杀伤武器运到了中国卖给日寇，投入到侵华战场上使用，逼迫重庆政府投降。黑玫瑰决心：无论付多大的牺牲，也要把这个大规模杀伤性武器摧毁。In winter, they make snowmen together.当高冷霸总变身温柔暖男，当游戏少女化身造梦密探，是欢喜冤家的聚头，还是甜蜜爱情的开始？When "cracking" the sand pile paradox, we often have to set a fixed boundary. If we say "10,000 grains of sand are a pile of sand", then less than 10,000 grains of sand cannot be called a pile of sand. Then it is somewhat unreasonable to distinguish 9999 grains of sand from 10001 grains of sand. This has to set a variable boundary, but what is this boundary? We don't know now. Then the value of "10,000 grains of sand are a pile of sand" originally set as knowledge will be reduced.
