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.

皇帝还是如往常一样不上朝，龙椅上不见龙顏，文武百官只能望龙椅遥拜，朝中大事就由崔丞相和秦公公代行视事。二皇爷感嘆皇帝终日在深宫沈浸酒色，不理朝政，坐视佞臣把持政务。
宋仁宗年间，开封府尹包拯，通称包青天，为官清廉，为民伸冤，强调「人在做天在看」、「举头三尺有神明」不畏强权，除恶务尽。我国自古以来，历朝历代，无论盛世还是乱世，朝廷中都免不了皇亲国戚特权横行，欺压忠良。在社会上，更是免不了贪官污吏，藏垢纳贿。或是土豪劣绅，官商勾结，鱼肉乡民，荼毒百姓……

Comparing the similarities and differences between the garrison forces of our army at position 169 and position 142, It will be found that there are a large number of people in position 169 (a reinforced platoon with a total of 45 people and equipped with recoilless rifles and other infantry powerful assault weapons, after being reinforced by the chemical defense squad, although the total number of combat personnel was reduced by 2 people, two 74-type flamethrowers were added, and the melee and assault capabilities were actually strengthened), The firepower is relatively strong, When the Vietnamese troops attacked here, they sent out strong defensive humanoid monsters. However, the number of people in position 142 is relatively small (only the "15 warriors" led by Li Haixin, And only equipped with rocket launchers, Without recoilless guns and flamethrowers, However, there are simple minefields with anti-infantry mines. This is better than at position 169, If a minefield is also deployed at position 169, Although it is not possible to completely kill the humanoid monster at one time, But it can certainly play a significant blocking role, To provide favorable conditions for the main position to carry forward its firepower and carry out annihilating shooting), The firepower is relatively weak, When the Vietnamese army attacked here, it sent out such small targets. Fast, unidentified creatures like "dogs", To sum up, the defense-strong humanoid monster stormed the powerful position 169, It should not be a coincidence that the Vietnamese army has certain tactical considerations when using "living biological weapons" to attack positions more suitable for its own characteristics with different "living biological weapons" instead of simply throwing themselves into the battlefield at will.
