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.越南剧《国民欧巴》Nation's Brother本剧讲述的是高富帅欧巴明英给妹妹嘉兰找的大学生家教，居然是和自己有过一夜Q的小可爱。作为对女人过敏的高富帅欧巴，和小家教会擦出怎样的火花呢！唯心小哥哥真的是贤惠啊，上得厅堂下得厨房，教得了书，贫得了嘴，顶顶子也想娶回家！CBS一口气宣布续订6部正剧，包括《#百战天龙# MacGyver》第4季。林多美成长于温暖富裕的家庭，她个性纯真善良，与丈夫陈笑飞有着美满的婚姻。文馨幼时和哥哥走散后被收养，养父去世后，养母对她从未停止过打骂虐待，很小就要为生计奔波。文馨与林多美的哥哥林多俊在国外相识相恋，回国后文馨嫁进林家，婚礼上意外发现小姑林多美的丈夫陈笑飞居然是她至今难忘的初恋。陈笑飞作为倒插门女婿，一直为林家工作出力却没有得到足够的认可，加上他身上背负着上一代的恩怨，内心里视林家为仇人，这一切让陈笑飞内心矛盾压抑。而文馨因为谎言得来的幸福并不牢靠，在婚后被林多俊发现真相并产生质疑，陷入信任危机，林多俊也因为发觉文馨的欺骗而陷入痛苦，并对文馨开始冷漠以待，文馨陷入越来越深的绝望，昔日两人的幸福生活不再。金智媛剧中饰演百货商店服务台工作的崔爱拉一角，她过去梦想成为一名播音员，所以每年都报考播音员公开招聘考试却每次都落榜，这是个不依靠别人，不信运气，不心存侥幸，非常自立的角色。50年代的德国,驻扎于Kaltenstein（冷石）的美军带来了崇尚个人自由主义的风气,因此两种文化开始猛烈的冲撞。。。
