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.来自KT星球的洛展，为了找寻遗失在地球的能量石救出被困的父亲，在地球上生活了三百年，为了方便寻找能量石，洛展一直以军人为职业。随着时间的流逝，洛展的特异功能渐渐消退，1980年和战友杜斌执行任务中，为了保护洛展，队友杜斌牺牲！而在遭到伏击落入山崖后，被一女孩相救……为了照顾战友杜斌瘫痪在床的父亲，洛展筑起了与外界的洪墙…10年后，救他的女孩离世，女孩的丈夫颓废成赌徒酒鬼，扔下年仅10岁的小天自食其力。洛展在与小天的打工交易中，慢慢与小天产生深厚友谊，因父亲欠债，小天被同样来自异星的秦蜀抓走，洛展再次打开心中的“洪墙”，展开孤身救援…如料想的一样。由乡村爱情保安队长宋晓峰领衔主演，程野、霍云龙、唐娜、燕飞主演的网络爆笑喜剧；《槑头槑脑》讲述了两个“呆头呆脑”的农村青年，为梦想来到城里，用自己的执着和善良，影响并帮助三个有着性格缺陷的年轻人成功转变的故事。故事中让你捧腹大笑的同时，最后能让你有着一丝感动。2.
