If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.
这部昔日的CBS旗舰剧集已经失去了一个好汉（Charlie Sheen被开除，Charlie Harper也随之死亡），现在又将失去半个好汉——因为种种原因（如果你相信CBS官方所说的「他要读大学」那你就太天真了），Angus T. Jones不再是该剧的常规演员，他的名字也将从片头字幕中彻底抹除。

The bright prospect of "a prosperous, democratic, civilized, harmonious and beautiful socialist modern power" described in the 19th National Congress Report is a new goal we will accomplish in the middle of this century and a enrichment and development of our goals for the second century. It reflects the requirements of historical progress, the happiness of the people and the sustainable development of the nation. From the 19th to 20th National Congress of the Communist Party of China, it coincides with the historical juncture of the "two hundred years" goal. We should not only build a well-off society in an all-round way and achieve the goal of the first century, but also take advantage of the situation to embark on a new journey of building a modern socialist country in an all-round way and march towards the goal of the second century. CCTV News (Focus Interview): After the centralized online shopping activities made by individuals, people have to face piles of packaged garbage. While you unpacked layer after layer of express packages and happily inspected new clothes and articles, have you counted how many cardboard boxes you have to throw away? How many packs of stuffing? How many plastic bags? The development of e-commerce and express logistics enables us to meet the shopping demand without leaving our homes, but at the same time, a large number of waste packages have also been generated. Because these packages have not been well recycled, most of them have been directly turned into garbage, which is not only wasted, but also brings a huge burden to garbage disposal.
