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.
Earlier this year, a blackmail software called "WannaCry" began to attack the Internet, from Chinese universities to British hospitals. In April this year, IDT, a Newark, New Jersey-based telecommunications company, suffered a similar attack, which was discovered by Goran Ben-Oni, the company's global chief operating officer. As Ben Oni said in an interview with the New York Times, he immediately realized that this blackmail software attack is different from other attacks against companies. It not only steals the information in the databases it infiltrates, but also steals the information needed to access these databases. This kind of attack means that hackers can not only obtain this information quietly, but also continuously monitor who accesses this information.

There are three main reasons for the peculiar smell of automobile air conditioners. First, there is exhaust gas leakage from the external engine and foreign matter in the air inlet, which leads to unpleasant smell from the air inlet of the air conditioner. In this case, it is very good to check and go to the repair shop to open the cover for inspection, which can be clearly seen. Second, the air conditioning filter element is too dirty. Regular cleaning and inspection can completely prevent the occurrence of peculiar smell. Third, the air conditioning pipes and evaporators are caused by mold, which is also more troublesome and expensive to maintain. The first two situations are relatively simple and easy to check. The following focuses on the third reason, why mold can be produced in pipelines and evaporators. The following master will give you a brief introduction.
