SYN attack is a kind of DOS attack. 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.少爷陈永业无心向学，却醉心于学武，自创天下无双弥猴无敌拳拳谱。一日，他与阿德在马骝山，发现被弟文豹陷害并打致重伤的文师父，二人一切动作就像猴子父女的动态。其后，文豹找人蹂躏小敏，文怒极，以打洪一虎来发泄，最后洪被打死，文哀痛。家业、阿德与小敏在文师父突导下苦练武功「醉猴拳」，终把于海洋等为非作歹之辈一并歼灭 …一个是上海知青子女——文嘉，一个是东北小镇青年——东阳。机缘巧合使他们相逢于上海，又是命运的拨弄，将两人的初次见面变成了生与死的隔离……生与死的经历只是一切的开始，在上海这座城市里：职场、情感、生存、事业、梦想、诱惑等等一系列现实层面的问题才是他们将要面临的最大考验。魔 都的魅力不仅吸引了他们，还有对他们灵魂的洗涤。面对种种选择使得这两个年轻人的命运轨迹离合交错，而真正的幸福到底是什么？也许每个人都会从文嘉与东阳的经历中找到自己的答案……这是一部充满时代气息、充满青春活力军旅题材力作。本剧主要讲述为完成“和平进驻”历史任务，时涛、何志远等一批优秀军人，面对由驻港英军、香港社会及客观环境带来重重困难和阻挠，最终出色完成任务故事。为进驻，驻军决定选拔一批出类拔萃基层军官。时涛、常凯平、靳大为、苏晴等少壮军人带着各自优秀来到魔鬼教官何志远面前，面对何志远“打击”，“刁难”和百分之九十淘汰率，几位青年倍受“磨难”，却因此显现他们豪气和追求。热心时涛替何志远之妻南珍找工作被误会成与香港女记者林嘉仪关系“特殊”，导致他几乎丧失先遣进驻机会，因此也牵连到何志远面临进港前“出局”。历史让他们终于站到英军上校劳伦斯面前。面对他强硬对峙，何志远表现出成熟军人素质和顽强军人作风尹旭很清楚苏角所言一点不假，北方的气候条件虽然艰苦，大片的草原才是原本最合适的养马地。　　孙承源饰演东久的大学同学奉斗植，是民宿Waikiki的联合CEO兼自由作家，但其实半失业中。听到这个消息，陈启也是一阵高兴，他的启明影视又多了一员大将。
