4. If no receiver processes the request, the request will leave the chain.If the connection initiator is legal, the firewall/proxy will receive the ACK, then establish a connection between itself and the server and disguise the address of the connection initiator. The firewall/proxy separates the two sides of the connection. This segmentation can resist SYN flooding attacks because the server has not accepted SYN from the attacker at all. As long as the firewall/agent implements some TCP-based defense policies, such as SYN? Cookies or SYN? Cache, he can protect all servers behind him from SYN flooding attacks.板栗道：等秦伯伯来了不就知道了。为了粉碎日军在山东的侵略阴谋，八路军组建了以营长黄鸣锋为队长的利剑特遣队，就在黄鸣锋执行任务时，找到了失踪的苏五巧，更有兰如剑、穆雪飞和柳迎春加入，利剑特遣队又壮大了起来。他们炸掉了日军的武器库，摧毁了日军一次又一次对共产党的武装围剿，炸沉了运送实验化学制剂的太和号货船。就在大家为完成任务松了口气的时候，黄鸣锋接到了上级总部传来的消息，日本军官杉木已将一批实验化学试剂运走，估计三天后将运抵前线。黄鸣锋立即率队员出发，他们劫持了一辆日军卡车，日夜兼程追赶杉木。黄鸣锋最终以自己的生命为代价，完成了任务。1984年1月，10岁少女惨遭杀害。15年后事件时效将届之日，曾为医师的乡田亮二（江口）突然自病院辞职。08年，转身成为国际刑事警察机构刑警的“亮二”与独自一人在巴黎旅游的女性（广末）相遇。他研修归国，并经介绍认识了东京?西警察署刑事的黑木（稻垣），不久黑木接到有关少女杀害事件的匿名电话打了进来……"Er... I really can't remember the model, it's green, probably so thick." Wang Zeduan could not remember the specific model of the explosive cylinder, Just said the color and gesticulated the approximate size with his hand, Later, I looked up the information and learned that The detonators used at position 142 were all Type 68 detonators, This is also a classic explosive barrel widely used throughout the Sino-Vietnamese border war. This type of explosive cylinder is 60 centimeters long each, As long as there is a need, it can be spliced indefinitely. The charge for each section is 2.2 kg, According to Wang Zeduan's description, At that time, the explosive barrel was made up of three sections. Then the total charge is as high as 6.6 kg, However, the high explosive bomb used in the type 66 152 mm howitzer, The charge is 6 kg, In other words, The charge of these three explosive cylinders is 0.6 kg higher than that of a 152 mm grenade. This is also basically in line with his description that it is more powerful than a shell. In addition, after being inserted into the ground, the two sections of the upper half form a certain blast height from the ground, In this way, the explosive power can be better exerted virtually to cover a wider area, so it is indeed reasonable that an explosive barrel can successfully achieve the tactical purpose of successfully clearing position 142 for the second time (the first clearance is 66-type directional anti-infantry mines and 72-type pressure/tripping anti-infantry mines).***前不久，张家回京后，为他和户部尚书赵耘之次女赵翩翩定了亲。
