Both these attacks and SYN flooding target the victim's TCP application and can interrupt the victim's service at much less cost than brute force flooding packet methods. However, SYN flooding is very different from other TCP spoofing attacks. SYN flooding attacks the services of the new connection without affecting the established connection, while other spoofing attacks break the established connection and cannot block the new connection from the beginning. SYN attacks can be stopped only by modifying the initial handshake program, while other spoofing attacks require checking every piece of data throughout the connection life cycle. What SYN flooding and other TCP spoofing attacks have in common is that they all depend on the attacker's ability to send IP packets that disguise the source address, while the same way to defend them is to deploy more address filtering or use IP Security Protocol (IPsec).自视甚高的记者余美仁（谢楠饰）是电视台里炙手可热的晋升人选，为了击败对手，她不惜挑战无人胜任的采访任务——前往南方的偏僻小城，去揭露一个有机农场的重大秘密。不料，余美仁在那里不仅遇到了“猪队友”——脱线少年小达（马昂饰）和中二少女莫莫（丁一一饰），更发现低调随性的农场主竟是自己的“克星”——小学同学李十全（方力申饰）。小时候只要两人相距50米以内，她就会出糗倒霉。然而为了事业，余美仁不得不和“克星”擦出亦敌亦友的火花，在保持50米距离的同时，一段阴差阳错又爆笑感人的爱情正在这个浪漫的小城悄然绽放。The most basic defense at the network layer is RFC? 2827 [3]. Using input source filtering, ISP refuses to route a packet whose source IP address does not belong to its source subnet further. Input source filtering can effectively prevent SYN flooding attacks disguised as IP. However, this method is useless at present because it is difficult to deploy on a large scale. Moreover, input source filtering cannot resist distributed attacks.且说黎章，待泥鳅和李敬文走后，看着发怔的妹妹认真道：小葱，你放心，就算是抢，哥哥也要帮你把泥鳅抢回来。远古时代，天地本无界，万物为求永生之道，皆因善恶动心起念，道不同不相为谋，渐形成了仙道与魔道两大势力，自此光明与黑暗对立。仙道为维护天地纪律、匡扶浩然正气，避免受到魔道破坏仙境，派出五大神兽，青龙、白虎、朱雀、玄武、麒麟五大尊者将具有魔道心性的生灵全部驱离仙境。不甘心被驱逐的妖兽，推派黑龙王为首，带领魔界邪灵妖兽们迎战反抗，撞毁四大天柱，引洪水泛滥，从此天地分界，烈火延烧七天七夜、生灵涂炭、哀鸿遍野。仙界将炼石补天的五色晶石打造成五大神器，朱霞镜、白灵珠、青云剑、金电钵、黑雷杖分别交由五大神兽前去平息乱象，麒麟尊者不幸遭到黑龙王的挟持，魔道妖兽才能安然逃至天外魔境。青龙以救出麒麟为名，号召四大神兽带着神器围剿魔境，黑龙王出面迎战，反被神器所伤，遭四大神兽制伏拿下，黑龙王从此被禁锢在昆仑仙境的仙母洞牢，以“千年寒冰石”冰封住，这场仙魔纷争才告平息。五百年后，修蛇贞儿（白蛇前世）化身为一妙龄女子，聪敏慧诘，贞儿和昆仑仙境修行的桑树神穹桑（许仙前世）相恋多年，因难舍情爱，修行因此受阻，迟迟未能
