Hearing this, I think of the famous carnivorous fish-sawtooth salmon, which lives in tropical waters and fears almost all creatures living with them, including crocodiles, which are known as freshwater overlords, and a more familiar name, namely "piranha". However, the serrated salmon has made such a "world-famous" reputation for its small size. In addition to the large number, In addition to his fierce temperament, It is also closely related to their unique tooth structure, The teeth of salmon, Is sharp on both sides, The middle is sharp and densely arranged, and has a strong cutting function for all kinds of skin and meat. Therefore, although its mouth is not large, it can basically tear off a large piece of meat with one bite. Similar examples include the teeth of great white sharks, which also have such functions. However, the individual size of great white sharks is too large to be compared with serrated salmon, and its lethality cannot be compared.小葱深吸一口气，轻声又坚定地说了一番话。Slow POST attack uses POST request method. The attacker sends POST request message to the target server to submit data. The length of the data is set to a large value. However, in the subsequent data transmission, only a small message is sent each time, which causes the target server to wait for the attacker to send data. If an attacker controls a large number of zombie hosts to launch such attacks on the target server, the server will run out of resources and cannot provide services normally.大家自然都交口称赞他。嗯，不用客气，好好工作就行了。The other two schemes are based on SYN cache and SYN? Cookies (see 6.4), simplifies the state initialized when the TCB is generated by receiving the SYN, and delays the instantiation of the full state [4]. In hosts that use SYN caching, a HASH tablespace with a limited size is used to store a subset of data that will be allocated to the TCB. If the ACK is received when the handshake is completed, the data will be copied into a complete TCB, otherwise HASH values exceeding the lifetime will be recycled when needed. In Lemon's FreeBSD, the SYN cache is 160 bytes for a half-open connection, while a full TCB is 736 bytes and supports 15,359 SYN cache spaces.他头一次在板栗面前摆长兄的威严，如同教训黄豆一般，口气严厉。
