It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.“渡江战役”是中国人民解放军实施战略追击的第一个战役，也是中国人民解放军根据党中央、毛主席“打过长江去，解放全中国”的伟大战略部署，向国民党残余发动最后全面进军作战的伟大起点。一群侦察战士，冒着生命危险渡江侦察，为了获得宝贵的情报和敌人展开了紧张激烈的周旋。他们面对的是敌人设下的重重陷阱与严密的围追堵截。侦察战士们以大无畏的革命精神，以及自身的智慧和勇气，像一把尖刀，深深插入敌人的心脏，在敌后游击队和人民群众的支持帮助下，在战火硝烟的洗礼中出色的完成了侦察任务，为我军顺利实施战役战术展开创造了有利的条件，为我解放大军顺利渡江，最终取得整个“渡江战役”的胜利奠定了坚实的基础。　　双男主妈是一个大家庭的佣人。一天太太流产了，算命的说这两孩子在一起会自相残杀云云之类的。当妈的很害怕，太太就说要不把小的（Neng饰演）给我，我保证他好吃好住。妈妈答应了，带着大的（Tre饰演）回乡下。两兄弟长大后接受命运的安排，果然相遇了，还玩得很开心。然而一个女军医（Plengkwan饰演）打破了平静。他们两个都爱上了她，开始抢女人大战！这是一个发生在中国一所普通中学里的故事，女主角索拉拉是个热爱孩子的年轻老师，在年级主任岳秀梅的反对和同学们的不信任中，当上了高一三班的新班主任。刚到班上，她就发现五六个同学已经染上严重的网瘾，成绩下降的很厉害，而隐藏在这背后的，是孩子们在复杂社会影响下的艰难成长。少年孟响是个网络高手，由于父母离异，家庭破碎，他与在商界赫赫有名的父亲有着巨大的隔阂。一次，他无意中结识了一个网络罪犯，从此他的生活陷入不自知的危险，而他的父母仍无法与他沟通，于是他们只有把希望放在年轻的索老师身上。女孩刘瑶瑶聪颖固执，在绘画上极有天赋。由于父母感情不合，缺乏家庭温暖，她渐渐对生活失去信心。在坚持自己热爱的绘画的过程中，得不到性格强硬的父亲的理解，产生了激烈的冲突，最终被逼上了绝路。少年向大伟出生在工人家庭，与简单粗暴的父亲矛盾重重。为了缩小他与父亲之间的鸿沟，索拉拉给了他一个小DV，让他拍(阅读全文)摄生活中的父亲。在与父亲朝夕相处的拍摄过程中，他看到了父亲工作的艰辛，生活的清苦，给了他深深的触动，这才渐渐了解
