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.无论如何，微臣绝不敢、也不会有半句微词。板栗，你们该去看书了。素贞（甄珍 饰）因嗜赌丈夫欠下大笔赌债后自杀身亡，而只得开设一家小花店独自抚养四个小孩。素贞有一男友俊富（柯俊雄 饰）为外洋船之高级船员，但碍于孩子的关系，无法成婚。老大至刚（吕良伟 饰）更受到爷爷挑唆，与母亲产生嫌隙……它伏下前腿，后腿略蹲。雅兰的父亲潘安诺四年前有了小老婆丽莉，雅兰就和她母亲Aong离家出走了。4年后，丽莉企图逼潘安诺写下遗嘱，潘安诺觉得对不起女儿，就将遗嘱写在爱犬亨嘟的画像后，并留言在狗圈上。丽莉随后带着男人迪沙来了，他们用逼潘安诺写下他们要求的遗嘱后，就立刻用安眠药害死了他。丽莉在丈夫的尸体前装出幅痛哭流泣的样子，但随后就和迪沙商量起卖房子的事情，这一切被爱犬亨嘟听见了，急忙考虑该怎么阻止。著名摄影师达伟来到了拍片现场，女制作人为他找了吉娜来做搭挡。回去后，吉娜和达伟的母亲与姐姐维娜发生了争执，双方相互挖苦起来。达伟赶到了，他声称自己要和吉娜一起买房子，买的正是雅兰家那一座——吉娜是丽莉的妹妹。雅兰回来了，爱犬认出了主人，它热情地欢迎了主人，可是丽莉却叫雅兰快带这只狗离开。忠心的狗夜里带主人去开潘安诺死去的屋子，还暗示屋子里面有问题，雅兰竟然看懂了，她将目前发生的一切告诉了自己的好朋友阿唐。可她刚进去，就被迪沙和其手下人抓住了。结果狗被扔掉，人也被被下令带去活埋。吉娜和达伟什么都不知道，他们一起买屋子亲故事由热爱棒球本田吾郎5岁时开始说起，失去母亲的吾郎一心想成为和爸爸一样优秀职棒选手，每天和父亲两人早晚都很努力地练习锻炼体力。失去母爱的吾郎，很喜欢幼稚园的桃子老师，把她当作亲生母亲般仰慕。此外，还有吾郎第一个陪他伴他打棒球的伙伴-佐藤寿也，和一群共同加入棒球行列的好友们相逢，而一连串充满勇气、斗志、亲情、友情的温情感人又热血激励人心的热血动人棒球故事，就这么开始了……
