The principle is that syn messages are first responded to syn_ack by DDOS protection system. With a specific sequence number (recorded as a cookie). The real client returns an ack and the Acknowledge number is cookie+1. The fake client will not respond. In this way, we can know that the clients corresponding to those IP are real and add the real client IP to the white list. The next access passes directly, while other forged syn messages are intercepted. The following is a schematic diagram of protection:?

Biting his thigh and not letting go, Ge Xiaolin's painful "wah-wah" yelling, I think we've just had an attack, A little respite, He asked two people to help him get this thing off his leg with me.

It is a rare eco-tourism scenic spot. Up the Chishi Creek, the natural wonders along the way, which are rippling, covered with thick shade, verdant trees, vines, deep and secluded, birds singing in the valley and peaks swinging back and forth, constitute a unique primitive ecological secluded environment. Oil leaks to waterfalls, and streams gurgle down cliffs more than 110 meters wide like knives, sparkling, spraying beads and splashing jade, just like silver blankets made of tens of millions of broken strings of pearls, which are lightly spread and inlaid on the cliffs. At Daixian Waterfall, the stream plummeted 139 meters down from the steep peak of the mountain. Clouds turned over and snow poured down. It was thunderous and spectacular. Standing under the waterfall, the smoke was steaming and confusing. If it is sunny, the rainbow in front of the waterfall is like an overpass flying in the air, which is very beautiful. At the top right of Daixian Waterfall is a Feixian Pavilion, which tells the beautiful story of fairies showing their saints and saving the people. Looking at the head by the railing, facing the abyss below, Dai Xian's double waterfalls set off on the left and right sides, with no momentum.
