SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.

"The first few hours of the battle were the same as before, We use all kinds of weapons in our hands in our positions.

We also have a lot of wounded on our side, However, after all, it is based on strong fortifications. More wounds, less deaths, In particular, the wounded are mainly minor, All of them can continue to fight without getting off the line of fire. At that time, my monitor was quite happy. If you play like this, There's not much pressure to hold position 149, The Vietnamese army that could fight could not even get close 400 meters away from the front of the position, As a result, it was only over an hour after he said this.

Just when something was wrong, First I heard a "buzzing" sound inside, At first it was a little bit, Later it grew bigger and bigger, At last it was so big that it could almost cover the shot when it was fired. No one in our position knows what's going on, All of them stretched out their heads and looked in the direction of the sound. When the "buzzing" sound reached its peak, they saw that a large area of flying insects flew vertically from the rainforest on both wings. If the number were small, whether the sound or flying insects could not be heard or seen at this distance, but now they could hear clearly.
