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).　　中国奇书《推背图》是唐初李淳风与袁天罡合撰，预言历代变革之事，准确灵验。唐太宗翻看此书后，大为赞赏，重赏李淳风，袁天罡因妒忌李淳风夺其功，怀恨在心。太宗死后，两人更将《推背图》图、文分家，两家成为世仇。而《推背图》从此绝迹民间。数百年后，两家后人阴差阳错结成夫妇……十八岁的拓海每天驾着父亲残旧的汽车送递豆腐，却无意中练得一手出神入化的飘移技术。对汽车毫无兴趣的他被父亲怂恿参加山路赛，以平日送货的旧车越级挑战著名赛车队，赛果似乎早已定断。岂料拓海竟在众人错愕之下胜出，一夜成名。凌晨风（朱千雪 饰）是新界北冲锋队的警长，一次执行任务中，凌晨风的行动遭到了名为关鼎民（王浩信 饰）的男子的阻挠，最终爆发了一场恶战，凌晨风的父亲凌海（罗乐林 饰）不幸意外丧生，这让凌晨风十分自责，然而，让她没有想到的是，自己竟然拥有了能够使时光倒流的能力，她斗志昂扬回到了事发三日之前，希望能够挽救父亲的性命。穿越天玄界，开局竟是辣鸡门派掌门人！都市氪金人重生游戏异界，拿玩家当走狗，收世界主角做小弟，看我怎么走向人生巅峰。《世上最美丽的离别》讲述一位平凡的母亲在人生的最后时光里，与家人重归于好享受最后亲情的感人故事。
