A fundamental and universal problem closely related to this aspect is related to the use of open DNS parser to launch DDoS attacks against Switzerland, an anti-spam organization. The open parser does not validate the IP address of the sender of the packet before sending back the DNS reply. Therefore, after the attacker deceives the victim's IP address, he can send a large amount of attack traffic to the victim, and the ratio of attack traffic to request traffic reaches 100: 1. DNS amplification attacks such as these have recently been used by hacker activists, blackmailers and blacklisted website hosts with great success.After "a long time", Ellie finally groped for the left-hand passage and "saved herself" successfully. Lying in the simulated incinerator, Ellie clearly realized how "reluctant to die" she was.《Notat》是一部以丹麦第一次恐怖行动的真实事件为基础的故事片。But we didn't realize it until the first big mouse emerged from the trench of the position. The big rats under the "earth beam" are only a few that dig shallow holes. Most of the deep digging is simply not visible from the surface, This is what I said just now. If you dig shallow, you can barely hit it. You can't see it deep, There is no way out, At last this thing was dug up and emerged directly from the trench wall. Then don't even shake the soil on your body, Bite at the sight of men, As the number of drillings grows, In the end, there were several times more rats than people in the position. Forming a situation of several besieging a soldier, Seeing the urgency of the situation, But 'the lame man caught up with the uneven road' (this is a folk proverb, meaning to make things worse, the house leaks when it rains at night), The big wasps that were repelled for the first time launched another attack, or from the left and right wings, in your words, this also formed the "open space" to cooperate in the battle. It is very strange that the big wasps did not attack the big rats on the ground at one time, but only stung people. They are obviously "a group" of dogs. Alas, then we will fight too badly. " Zhang Xiaobo said with a long sigh here, and I couldn't help but be surprised. This big mouse can dig out more than 100 meters of passages underground in more than half an hour. How fast is this? That's a speed of more than 30 centimeters per minute. Although it is said that the soil on the southern border is softer and no harder than that in the north, it can dig more than 30 centimeters per minute. This speed is really staggering.Tip: There are very few M codes for channel goods. L medium tube is suitable for 42 ~ 46, long tube is not suitable for friends below 180, unless you want to become Uncle Drew.About crayfish, Thirteen years is my first year of raising, But the understanding of crayfish has been known since childhood, About '94, Before that, we didn't have any crayfish in our area either. I don't know where it came from. Slowly began to flood, There are crayfish everywhere, At first, I started fishing for lobsters, Is to tie some food with fishing line, Like lobster tails, It's easy to catch, Slowly the lobster got smarter, Begin to add the net copy, With a pole in one hand and a net in the other, Later, this was not easy either. Began to use a small net to put lures in it, Then lift it up, Catching shrimps in cages is an efficient catching method invented in recent years. This method has also resulted in fewer and fewer wild resources. Lobsters used to be very cheap. I remember in 1994, the small ones were generally 20 cents and the large ones were generally 3-40 cents. In recent years, the prices have been rising higher and higher, and shrimps are becoming fewer and fewer. How many people have entered the ranks of lobster cultivation one after another, and how many people have left at a loss.
