If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.I thought this thing was the same as before, Is to rush up and bite people, So we're just shooting with guns, When the distance is close, throw it with a grenade. At the most dangerous time, even mines are thrown out, At that time, the 'round head' anti-infantry mine (still referring to Type 72 anti-infantry mine) had a 'bolt' (i.e. Safety ring) under it. Just pull it out, Throw it out like a grenade, But more powerful than a grenade, As soon as a large area is blown up, But because it is heavier, More than three grenades, Therefore, those with weak throwing ability generally dare not use it like this. Because I'm afraid I can't throw it out of the safe range and blow it up to myself, But fortunately, whatever it is, As long as you want to attack, It must be an attack on the ground, We have a great advantage from a high position. Throwing explosives from high to low can increase the throwing distance, Even if you can't throw it far away, After landing, you can also roll down a little further distance. Therefore, some comrades who throw grenades not far away can also throw mines away from a safe distance to strike the enemy. Then there is the explosive cartridge, The vast majority of people can't throw out three pieces of explosive cartridges in one go like a company commander. And it is too wasteful to throw them all like that, So he threw the explosive cartridges out one by one, When the "big grenade" is used, The reason why I dare to do this and make such "rich" moves is because there are not many others in our positions, that is, grenades, mines and explosive cartridges are plenty of explosives, and many to "tube enough", thanks to these, otherwise in the period of time without artillery support, the Vietnamese army's offensive forces increased several times, and the guns in hand alone could not hold up completely.1941年12月7日，日军成功偷袭珍珠港，12月8日日本向英美宣战，并全面进入上海租界区。一艘由香港开来的邮轮停靠在上海码头，船上的两名乘客陆昊然（世界反法西斯同盟组织成员）与安妮一下船就遭遇到一场惊险万分的追杀，黑帮、汪伪、军统三方势力都是冲着他们而来。与此同时，日军也在上海公共租界搜捕英国英纳格码破译专家英裔华人周弘文。原来第二次世界大战期间，德军大肆屠杀犹太人，在上海著名犹太商人维克多的号召下，中国的犹太人为世界反法西斯同盟组织捐助了一笔巨款并交由维克多管理，维克多委托世界反法西斯同盟组织保护他唯一亲人安妮来到上海。太平洋战争爆发后日本进驻公共租界，并将维可多软禁起来。各方为了从维克多处获得巨款下落和密码，这才有了追捕安妮一幕。在我党地下组织成员安伯、陈重以及打入军统内部行动队长马俊杰的帮助下转危为安。However, in the past two years, the "positions" of the NPC and CPPCC have been somewhat tilted to beautiful journalists from all over the world.
