Facing TCP's three-way handshake protocol, how should attackers launch attacks? The attacker first intentionally initiated a handshake packet. After receiving it, the server puts it into the waiting queue and returns an acknowledgement. Secondly, the attacker will no longer send the third acknowledgement packet, thus the server will make multiple retransmissions (the Linux system configures the number of retransmissions through tcp_synack_retries), consuming a lot of extra overhead, and the waiting queue will be occupied, even the waiting queue will be full, eventually causing the server to be unable to receive the client's request. This is the attack.
The police continued their search around. 200 meters south of the house was an abandoned pumping station. After careful investigation of the wall to the west of the pumping station, the investigators made another major discovery: some dripping and scratching blood. The blood was covered with loess, but traces could still be seen. Following the blood, the investigators carried out a blanket investigation to the south and found a hidden cave 100 meters away from the pumping station. The terrain was relatively partial and it was difficult to find. When the investigators approached the entrance of the cave, dripping blood appeared on the rock wall under the entrance of the cave. Intuition told the investigators that the cave would uncover the mystery of the disappearance of the couple. They carefully entered the cave to explore, From the outside to the inside, the space in the cave gradually widened. There was a large amount of corn straw on the ground. The corn straw was piled thickest in the northwest corner. Investigators moved the straw upward and found a relatively small foot. After another move, they found two other relatively large feet. Preliminary analysis showed that one man, one woman and two bodies were inside. After identification, the two bodies in the cave were newly married couple Sun Gang and Li Hong.

In the above code, we use three functions, order500, order200, orderNormal to handle its own business logic, If the current own function cannot handle things, We pass it to the following function to handle it. By analogy, Until there is a function that can handle him, Otherwise, the responsibility chain mode will leave the chain directly, telling that it cannot be processed and throwing an error prompt. Although the above code can be used as the responsibility chain mode, we can see from the above code that the Order500 function depends on functions such as Order200, so there must be this function, which also violates the open-closed principle in object-oriented. Let's continue to understand writing flexible and detachable responsibility chain nodes.
Physical Attack +35
However, under the circumstances at that time, I thought these things had little effect, because after we knocked them out, we began to gather in more quantities and launched attacks on positions from all directions. Judging from the form of attacks, they were quite organized and definitely beyond the reach of ordinary wild animals.

The firewall sets the SYN forwarding timeout parameter (the firewall for state detection can be set in the state table), which is much less than the timeout time of the server. When the client sends the SYN packet and the server sends the acknowledgement packet (SYN + ACK), if the firewall has not received the acknowledgement packet (ACK) from the client by the time the counter expires, it sends the RST packet to the server to cause the server to delete the half connection from the queue. It is worth noting that the setting of gateway timeout parameters should not be too small or too large. If the setting of timeout parameters is too small, it will affect normal communication. If the setting is too large, it will also affect the effect of preventing SYN attacks. This parameter must be set according to the network application environment.

Hello, how to set the Internet parameters of Apple's mobile phone: you enter the mobile phone menu, select "Settings"-"General"-"Cellular Mobile Network"-"Cellular Mobile Data Network" in turn, and enter "CMNET" at the APN of cellular data; Other items need not be filled in or changed. After the setup is successful, turn off the mobile phone and restart it. Warm Tip: If the mobile data traffic package you are using only includes traffic from cmwap access points, change the APN to "cmwap". Please refer to.
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.
