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.这是一部以康熙末年,其九个儿子为皇位而明争暗斗为背景的清朝古装戏，康熙九子权欲薰心，为夺皇位，不择手段，骨肉互相残害撕杀，展开了中国历史上一段最腥风血雨的宫庭斗争。其间穿插武林争斗,外族叛乱,边疆争战,战场杀敌等,气势宏伟.能兼顾文戏和武戏,精妙的宫廷争斗和大气的沙场争战的电视剧只怕很难再出其右了。Simple test classes:Move the mouse to the left margin of the last paragraph of the document and double-click the left mouse button to select the paragraph.

By default "three columns", Word documents have not changed to three columns according to the original setting, but only two columns of text, and some documents have only one column after three columns are typesetted under the same circumstances. Why is it normal to "column typesetting" other paragraphs of the document, while the same operation will cause problems in the last paragraph of the document?黄豆不相信地问道：大哥能有那东西？净哄我，当古籍是大白菜么。听说皇上这回本是要提拔你二叔进京做官的，谁知倒霉，让南雀国的人抢了军粮，这才惹了祸。《黑白人生》讲述了某县县长面对私企老板的拉拢毫不动心,以致妻儿惨遭杀身之祸,最终战胜邪恶的故事.山阳县县长郑楠的妻子和女儿被蒙面人杀死在自己的家中,这一刑事案件震惊了整个白山市,案件侦破两个月没有丝毫进展,白山市委决定重新调用侦破力量,在新上任的山阳县公安局局长李斌良率领下,公安队伍与邪恶势力展开了一次次的较量.于是,一个个官商勾结,黑白混淆的腐败案件开始浮出水面,最终主人公郑楠和杀害妻女的元凶同归于尽.
