The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.　　佟家在青河镇看上去是家大业大，风光体面，富贵显赫，内里却极不安牌坊下的女人宁。佟善群的二太太徐凤琴出身低微，是佟善群从妓院里把她娶回家的，所以，凤琴一直认为自己在家中没有地位，整天胡搅蛮缠的，不是找大太太素蓉的茬，就是看弟媳其贞碍眼。就连她刚满九岁的亲生儿子佟喜才迎娶进门的“大”媳妇方瑾，更是受尽了她的虐待和折磨。剧中中两位男主人公，一个是有才智的百万富翁查理，他的妻子年轻美丽；另一个是时尚摄影师巴尼，他为查理工作并且对查理拥有金钱美女十分妒忌。两人因飞机失事而受困阿拉斯加的荒原，一场无情的生死决战也由此展开，而在这荒芜的天地一隅，最大的危机不是来自自然，而是人性的阴暗面——背叛及谋杀。　　泰瑞和鲍勃是新墨西哥两名无赖、腐败警察，靠勒索犯罪份子牟利。一次，欲通过雷吉谋取100万，不料黑道老大摩根黑吃黑卷走80万。泰瑞和鲍勃向摩根恐吓索求80万，又不料被摩根动用关系将二人踢出警局。接着，泰瑞、鲍勃杀向摩根老巢，一场西部牛仔式的枪战上演……But it did make him the most outstanding writer in the United States at that time and even the most outstanding writer in the world.除此之外，另有两个文静秀气的小姑娘，虽然有些拘谨腼腆，却并不忸怩，目光也纯净。An unlikely trio traverses a desert planet in search of a rumored lake- and the hope for a better life that it represents.
