Chapter 325 Objectives, Academic Affairs Office

Zhang Da asked Lin Hong to enter the password. He went in and played for a while. In the end, he was a little disappointed. He found that the LINUX operating system was too difficult to use. Sure enough, it could only be used by technical experts. There were very few graphical things. Basically, it was similar to DOS, which had to remember a lot The same.

The way technicians think about problems is completely different from that of ordinary users. They think that the command line is easier to use than the graphical way, which is faster and more efficient. THEREFORE, AT THE BEGINNING, LINUS WINTED ABOUT GRAPHICAL THINGS AT ALL. AFTER ALL, THE LINIX HE MIMITTED IS A SYSTEM USED ON LARGE WORKSTATIONS AND SERVERS. USING GRAPHICAL INTERFACES, IT ONLY TAKES UP A LOT OF CPU AND MEMORY RESOURCES, AND IS NOT NECESSARY AT ALL.

The graphical login interface used by Lin Hong before is just a graphical shell added to the core.

In fact, with the popularity of the WINDOWS system, Lin Hong has also been thinking about whether the operating system pursues easy-to-use operation, gorgeous interface or performance.

He hasn't figured out the case clearly, but he already has a general understanding, which is why he added a shell to the system on his notebook.

Of course, this shell is still very simple, a little similar to the early days of WINDOWS, many design ideas still imitate WINDOWS.

After a while, the last member of dormitory 604 also arrived. Like Pan Pan, he was also a fat man, but looking at his size, he seemed to be fatter than Pan Pan. When he walked, the fat on his body trembled.

"Yo, how many brothers have arrived? I'm sorry that I'm late. Let me introduce myself first. My name is Li Qi, from An H Huainan.

As he was talking, he groped a few times from his big trousers, and unexpectedly took out a bag of soft Chinese, and each person sent one. From his skillful movements, it can be seen that he is an old smoker.

This fat man is a familiar person. Although he has just arrived, after a few words, he sent out a circle of cigarettes, and everyone immediately became familiar with each other, as if they had known each other for a long time.

Of course, this also has something to do with each other. After all, we will be brothers in the same dormitory in the future. We will spend four years together, and it will always be more comfortable to get along well with each other.

Fortunately, the personalities of the four people are not bad, and there are no people who have strange personalities or care about everything.

The four people were sorted by age. As a result, Lin Hong found that he had become the eldest. He used to be the youngest, but now he has become the oldest, which made him sigh a little.

Zhang Da is the second, Wu Dong is the third, and Li Qi is the fourth.

"In advance, you can call me Tarta, Zhang Da, or Xiaoda, but you are absolutely not allowed to call me the second. Do you hear me?" Zhang Da solemnly declared.

The other three looked at each other in unison and said, "I know the second brother!"

After saying that, the three of them laughed and were so angry that Zhang Da wanted to beat people. As a result, it was tragic to find that he was the shortest and the smallest of the four.

Playing and joking with them, Lin Hong really returned to his school days at this moment.

He enjoyed this feeling very much. Due to his special experience, his growth process was a little incomplete and he entered the adult world prematurely.

In the past, he did not get along well with others at all. Except for making a few friends when he was studying in the United States, he basically rarely communicated with others. Moreover, these people are basically much older than him, and their peers can't communicate equally at all.

It was not until this moment that he felt that he had really returned to his school days, which was the student life he wanted. He is innocent and heartless, communicates equally with each other, and has no other miscellaneous experience of cruel war and the baptism of humanity. He has a special experience of this pure friendship.

While chatting, they talked about the topic of girls.

This topic is basically one of the hottest common topics in boys' dormitories.

"I just came to the dormitory and saw an unbelievably beautiful girl. I don't know if she is from our college." Fatty Li Qi smashed his mouth and said.

Zhang Da's eyes lit up as soon as he heard it: "Oh? Is it the one with long hair, about 1.65 meters, with a ** childlike face?

"Yes! Did you see it too?" Li Qi felt that he had met a bosom friend.

"I saw it two days ago. It's not from our college." Zhang Da recalled the situation at that time, "I was shocked after seeing her, followed her for a long time, and figured out what her name was, hey hey!"

"Damn it! Is it true or not? Li Qi found that he had met a high man.

At this time, Lin Hong and Wu Dong also found that they still underestimated Zhang Da's shamelessness.

Zhang Da said proudly, "If I heard it correctly, her name should be Su Mei."

"Which college is that?" Li Qi asked.

"I don't know. I still need to continue the investigation."

Li Qi couldn't help but be disappointed when he heard this: "I thought you had investigated all the information clearly!"

"It's not easy to know her information. It must be in the server of the Academic Affairs Office. The last time I went to the counselor's office, I saw him search for my information from the database."

When Zhang Da said this, he immediately patted his thigh: "Yes, why didn't I think of it before! We can hack into the database server of the Academic Affairs Office!"

His words aroused great interest in both Li Qi and Wu Dong.

As students in the Department of Computer Science, they have also heard about this area. Of course, Zhang Da told him this knowledge of Wu Dong.

Li Qi asked, "How to invade?"

"I don't know, but Lin Jiang should know, right?" Zhang Da looked at Lin Hong, "Lin Jiang, do you know the hacking technology?"

The main reason why he asked this question is that he saw that Lin Hong is using the INUX operating system. As far as he knows, those who currently use this operating system in China are all technical experts.

The other two also looked at Lin Hong expectantly.

"Lin Jiang, if you can successfully capture the database of the Academic Affairs Office, we will call you the boss in the future!" Li Qi insidated.

Zhang Da: "I agree!"

Wu Dong: "I agree too!"

"I'm the boss, okay?" Lin Hong was indifferent.

"That's different. Now you're the boss just because you're a little older." Seeing that there seemed to be a chance, Zhang Da quickly said, "Other than that, I will help you get hot water for a month, and each of the three of us will have ten days."

The school's hot water room is a distance away from their dormitory. Every time they get hot water, they have to run far, which is very inconvenient.

Lin Hong immediately agreed: "It's a deal!"

Lin Hong has planned for a long time. It doesn't matter if they know about this degree of invasion. Everyone lives in a dormitory. Sooner or later, they will know about it. Now take this opportunity to make them mentally prepared.

Another reason why Lin Hong did this is mainly because he has determined that these three people have good character and are brothers worth dating.

Lin Hong opened his notebook and logged in to the character interface.

The other three people suddenly gathered around.

This live performance hacking, this kind of opportunity is rare, and the three of them are looking forward to it. At the same time, they also began to speculate in their hearts what level Lin Hong's technology was and what he did before.

"Well...should the door be closed first? It's not good to be seen by others." Lin Hong took a look at the open door.

"Yes, yes, it has to be kept secret." Zhang Da immediately ran over and bolted the door.

Lin Hong can be said to be handy for this degree of invasion, but he didn't want to exaggerate too much, so he decided to do it step by step.

Although there is no Internet here, the campus network in the school is connected, and the major nodes in the school are also within the campus network.

Lin Hong has learned before that Shuimu University is the earliest university of the domestic campus network, which was established as early as 1987.

In order to make them easy to understand, Lin Hong decided to find the simplest way to invade.

"Before the invasion, I have to disguise it, so that even if the network administrator finds the intrusion, it can't successfully locate our IP address." Lin Hong explained to them.

"Do you still want to do this?" Wu Dong had never come into contact with this area before, so it was a little strange.

Zhang Da has a relatively good understanding of this area: "Of course, after our computer is connected to the network, it will be assigned to an IP address, and this IP address usually does not change. Even if it changes, it will change in a very small direction. At that time, they will definitely check it accurately."

Li Qi echoed, "Yes, yes, yes, that's the truth.

"How to disguise it?"

"You can jump through the proxy server." Lin Hong replied, "The proxy server is equivalent to a springboard. We first connect to the proxy server and then access the target, so that if they find it, they will see the IP of the proxy server"

"It turns out that the function of the proxy server is like this!" Zhang Da suddenly said, "I used to hear people or magazines talk about proxy servers. I don't know what it means at all."

"The proxy server has many functions, such as the control of access rights, the control of Internet time and traffic, and acts as a firewall to become a channel to connect the intranet and the Internet. For example, if our computers want to access the Internet, they must go through the proxy server in the network center. On the gateway server, they can monitor what website the students in the whole school are on.

"Ah? Can they all see it?" Zhang Da was stunned. In this case, he obviously never knew, "If I go to some foreign websites... adult websites, they can also find it?"

Lin Hong said nothing: "Of course."

At this time, Wu Dong interrupted, "In this way, isn't it meaningless to use a proxy server to invade?"
