一九五零年，抗美援朝时期，国民党反动派制定了破坏我铁路运输及军用物资的“春雷计划”行动。为粉碎敌特阴谋，以韩立冬和刘玉娥为代表的安东铁路公安人员在我党领导下密切合作，慢慢接近特务组织。特务头目周春山频频用计，韩立冬见招拆招，终将特务组织一个个连根拔起，却招致周春山的暗中追杀。在公安处长郑新民的精心策划下，韩立冬成功打入敌特内部，凭借过人的侦查手段，找到日本关东军当年藏在安东的秘密军火库地图和一份极其重要的潜伏特务名单，及时铲除一直深潜在公安内部的特务“老刘”。经过一系列紧张而激烈的战斗，周春山及其特务组织最终被一网打尽，而被美军炸毁的鸭绿江大桥也在群众帮助下及时抢修完毕，从而保证前线物资供应。尹旭说完之后，看着众人笑而不语。新的鬼片吉祥之家 2集一个短剧。第一个故事~ 招灾大学生。。。。。。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.我们进去，你慢慢和我细说。说到这里，千年血魔轩辕法王发出桀桀的冷笑声。身旁一军士喘着粗气奔来：都督。
