        1985年，那时正是美苏两极争霸越演越烈的年代，史泰龙自导自演的洛基系列也出到了第四集，这一系列影片旨在振奋人心、宣扬美国精神。这一集讲述的是洛基（西尔维斯特•史泰龙 Sylvester Stallone 饰）的好友前美国拳王到苏联出战他们研制的拳击机械人，不敌对手最终身遭不测。为了帮好友复仇和维护国家荣誉，洛基决定再次出马。  出战前，洛基进行了一系列精心的准备工作，他深入到大自然，利用自然的艰苦条件刻苦训练。当一切准备妥当，洛基和苏联拳王――拳击机械人的决斗展开了！往屠龙刀刀口上击落，只听嗤的一声轻响，铁锤的锤头竟然从中一分为二。这片土地完整成一个单独的块，不容易受到来自外部的侵扰，正是江南最为肥沃富饶的土地，鱼米之乡。赵锋就不说了——他性烈如火，你二人这些年辗转沙场和朝堂，功业丝毫不输秦霖　　奶奶说话颠三倒四的，反而比没患病前风趣许多，也许之前就是太压抑了吧。无意间，奶奶说起自己年轻时的往事，说自己当年可是轰动一时的阿哥哥公主！参加阿哥哥舞蹈比赛后，得到冠军，是整条村子的风云人物，连当时“万草油大王” 的独生子“万草油王子”也对她有意思。Tango听了，根本不信，也不想去向爷爷求证，反正他对凶巴巴的爷爷没什么好感。当初受伤逃走，他不敢lù面便选了一处地方安心养好伤势。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).
