Exclusive Achievement Award (Award will be received when reaching the corresponding charm level for the first time)Moon God Story Worker, kill itSYN 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.纳粹时代结束十二年后，大多数公民还在纳粹政权的恐怖阴影中。总检察长弗里茨·鲍尔一直致力于纳粹罪行的举报。根据1957年的线索，他找到了前党卫军阿道夫·艾希曼的下落，鲍尔希望将艾希曼绳之以法。但他反复受阻，高级检察官乌尔里希和BKA员工保罗·格布哈特破坏鲍尔的进程……田夫子怒喝道：这种人，你明白自己跟他们毫不相干，正该庆幸，如此颓废，是何道理？是何道理？田遥痛苦地想，他该庆幸吗？煎熬了几个月，没想到是一场笑话。婚姻失败对于已经三十多岁的女作家法兰西斯来说，是一个很残酷的打击。幸亏朋友体贴窝心，专程安排她到意大利托斯卡尼去旅行一趟。想不到，托斯卡尼这个美丽得令人窒息的城市，竟然改变了法兰西斯的后半生。法兰西斯在托斯卡尼看到了一个郊外别墅的广告。本来并无太多打算，然而接下来的种种巧合却让她和这幢房子接下了不解之缘。
