The principle is that syn messages are first responded to syn_ack by DDOS protection system. With a specific sequence number (recorded as a cookie). The real client returns an ack and the Acknowledge number is cookie+1. The fake client will not respond. In this way, we can know that the clients corresponding to those IP are real and add the real client IP to the white list. The next access passes directly, while other forged syn messages are intercepted. The following is a schematic diagram of protection:?里面传来了轻快的脚步声，隔门十分期待地问道：谁？人在危急时刻，总会发现自己有惊人的潜力，杨长帆竟然记起了刚刚赵文华随口提到的名字。"There are close combat, But that was later, At the beginning, They rush up, Let's fight, Because the speed is too fast, Most of them can't be hit, Only a few machine guns were shot down by strafing. It is too difficult to hit an automatic rifle with a single shot, Fully automatic shooting and uncontrollable, Fortunately, in the end the mines blew them up. I don't even know what they are, However, no one can see that landmines play an important role. In order to be able to withstand the possibility of a similar attack, The company commander sent four comrades to re-mine, We provide cover up there, As a result, they had just finished their cloth and were ready to come back. That is, the time of the front and rear feet, Another batch rushed up below, This time the number is much higher than last time. I took a look at it, It is estimated that there are at least 30, When the reaction comes back, They rushed up to the four comrades, The two sides mingled, Dare not throw grenades, Afraid of bombing one of his own, Shooting is also restricted, Still afraid of accidental injury, With such a delay, three of the four comrades were tackled by those things, and the remaining one was quick in legs and feet. I remember he first shot with his backhand and knocked out the one closest to him, and then he wanted to save people. Besides the company commander, there was also a platoon officer on our side. The platoon officer shouted to death with a broken gong voice, shouting only two words, "come back!" , probably out of instinct plus the role of command, he hesitated for a moment and turned to run back, and he ran back, is to pick up a life, but the other three comrades, born by those things to tear, some bit off the throat, some was torn off the arm《恋爱未遂》是一部讲述无数次告白但总是失败的青春单恋故事的网剧。 姜蔚蓝（孙相渊 饰）好像患有分离焦虑症，当周围没人在旁陪伴时，他就会感到不自在。他的人生目标是能找到一个可以无时无刻陪伴在身边的人。蔚蓝18岁时想要恋爱，但事情并不如他想象般发展，无数次告白总是以失败告终。这次他鼓起勇气向10年好友李诗源（杨惠智 饰）表白，这段青涩恋情会如何发展？C4剧情片，共四集。 Glyngolau是威尔士的一个小城镇，镇里的一个大型建筑项目将为小镇带来巨大利益。突然有一天，工地发生爆炸，事故造成多人伤亡。而就在爆炸当天，几个孩子不知何故闯入现场，没人知道他们与爆炸是否有关联，家长们不愿相信他们的孩子是爆炸的罪魁祸首，他们渴望事实真相，试图寻求真正的正义。可他们能找到真正该为这场悲剧负责的人吗？ 本剧为第四频道广受欢迎的丑闻三部曲中的最后一部，前两部分别为《#国家淫才# #National Treasure#》（2016）和《#姬芮# #Kiri#》(2018)。如果说《国家淫才》的主题是耻辱，《姬芮》的主题是责备，那《意外》就是在讲述一座城镇在事故灾难后寻求的正义。 本剧的编剧是杰克·索恩 Jack Thorne（《#黑暗物质三部曲# #His Dark Materials#》）。早在剧本动笔前，故事就已经确定要围绕“阶级”与“正义”展开。但多次创作均不合心意，直到6·14伦敦公寓楼火灾事故发生，这场悲剧成为了Thorne的直接灵感来源。 随着对事件调查的深入，Thorne发现，类似的重大灾难事故有很多，但是相关的法律制度却少之又少，很少有人会因此付出代价去坐牢，甚至很多地方连善后都做不好。他在接受采访时指出英国在拆除易燃居民楼外墙材料的工作进展甚微，按目前的速度，要到2030年这种材料才能全部从英国拆除。而现在还有14个家庭没有找到住房，很多人依旧住在那座大厦，他们无处可去，又卖不掉这些公寓。他们东奔西走为自己呐喊，虽然激起了一些水花，但没过多久又会被人遗忘。Thorne补充说，这些灾难事故其实很难找出具体某个人的过错，但可以确认的是这是司法系统的失败。拿外墙材料拆除工作来说，很明显司法系统没有对拆除公司造成足够的震慑。我们需要警察的唯一理由就是预防犯罪的发生，可如今这些潜在的、可以预防的犯罪依然发生，发生之后又无法妥善解决，这就意味着司法系统的失败。 Thorne认为只要正确看待并讲述这次事故，就一定会伤害到事故相关者，这样一部电视剧即便成功也是建立在悲剧与生命之上的成功。于是Thorne决定不直接将这次火灾事故搬上电视荧屏，而是虚构了一个新故事。郑长河几句话一说，就不怯场了，但把啥礼仪规矩忘到九霄云外去了，他站在偏殿中央，绘声绘色地告诉道：这娶亲哩，得看人。With that, little Charlie's sparkling eyes suddenly looked much darker, shrugging his head and muttering in his small mouth. Grandma Lily looked at this and quickly put little Charlie's hand in her palm and pulled it to her side.
