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.可是，他一生刚硬要强。描述围绕SNS的家族的崩溃与再生的新形式家族剧。主人公是咖啡店的店长・篝星。是位周遭对她有好评的女性。但每天夜里抱着黑色包要前往的地方，有着完全不同的另一个人格，这个秘密连家人、朋友与同事都不知道。星的一家四口，乍看之下是一般的幸福家庭。平成20年、静岡県の国道高架下で須藤勲（尾美としのり）が殺害される事件が発生。捜査に当たったのは富士裾野署刑事・日下悟（小泉孝太郎）。須藤は34年前に静岡で起き未解決になった男児誘拐殺人事件の被害者・尾畑守君の実の父親だった。事件解決の糸口はこの誘拐殺人事件にあると踏んだ日下は、20年前の昭和63年、時効目前に迫った誘拐殺人事件の再捜査を指揮した重藤成一郎（上川隆也）に捜査協力を頼みに行くが……。《粟裕大将》以战争长卷的形式，集中展现了粟裕将军在解放战争期间那段纵横决荡、富有传奇色彩的战斗经历，充分展示了粟裕将军在党中央毛主席的关怀指引下所展示的卓越指挥才能、军事才能和智勇双全的大无畏战斗精神，既回顾讴歌了粟裕将军富有传奇色彩的一生，也全景式地展现了当年华东解放战场的战略局势。Bee原本是大明星，性感又有钱；Pang是草根家庭的小家碧玉。Bee的老公／男友James背着她跟Pei偷情被发现，机缘巧合Pang上了Bee的车，Bee飞车（貌似是追James或是Pei）出了车祸，两人在昏迷中灵魂对调。出院后，两个女人各自被老公／男友领回家，Pang在Bee的身体里，体验到了有钱人的生活；而Bee在Pang的身体里，却要与Guy共处蜗居。当然最难堪的还是各自要和“不认识”的男人......　　祝言之父亲，昔年因与今日成为高官的钱荣威结下仇怨，而遭到陷害并想霸占言之。幸亏得到新晋少将马承恩帮助，在祝父老朋友草头的帮助下，把女扮男装的言之安置在逍遥山内学习武功暂避。
