The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.

? The website is changing, the audience is changing, and the creators are also changing. Today's audience is not in the age when information was relatively isolated as we did at the beginning. They are in an information age. The relationship between people on the Internet is getting closer and closer. As a result, they are more and more eager to communicate with others, express themselves, desire others to identify with themselves, and people are less and less willing to be isolated. I can put forward a phenomenon that when a person plays with obstacles, the people around him are also willing to be a repeater, for fear that they will not be able to keep up with the topic and will be despised and isolated. On the barrage, we will find that there are really many repeater machines ~ ~ ha ha. And some of the barrages, to be honest, have already seen bad, but they are still happy to knock on the keyboard and press enter. Finally, I also began to click to close the barrages.

"Can afford to lose" seems to be a low profile, but in fact it is not easy to do it. What can really afford to lose is either young enough or has a sufficient reserve of resources. This is often a paradox in investment. The more you can afford to lose, the better your mentality will be, and the less likely your behavior will be to deviate. On the contrary, the more you can't afford to lose, the more you want to gamble and turn over the big ones as soon as possible. Without jumping this psychological trap, it is difficult to really form an investment consciousness.

Mr. Sun Yimin's guidance to the practice team is not only reflected in practice, but also in the safety, life, study, life and other aspects of the team members. When this activity was slightly conceived, Mr. Sun repeatedly stressed with the captain the safety of the team members' stay in school, the transportation mode and route for two days out, etc. The teacher also repeatedly asked about the cost of this activity, and was very worried that some classmates would have family difficulties and could not afford the cost. On the day before the start of this summer's social practice activity, the team leader and vice-captain were worried that the content of the activity was not full enough. Teacher Sun Yimin immediately built a bridge for the team and introduced the team to Dalongfang Science Park. Within 9 days before and after the activity, two days of pre-contact and three days of probation, Mr. Sun Yimin took out the whole three days to accompany the team to three probation bases to accompany and guide the activity. Before and after each activity, in order to make the team members better transform what they have learned in practice into their own abilities, Mr. Sun Yimin encouraged the team members to actively ask questions and establish contact groups with successful people they met during the probation process, so as to facilitate better communication between the team members and role models.
