Chapter 325 Objectives, Academic Affairs Office

Zhang Da asked Lin Hong to enter the password, he went in to play for a while, but in the end he was a little disappointed, he found that the Linux operating system is too difficult to use, and it is really only used by technical masters, there are very few graphical things, basically similar to DOS, you have to remember a lot of commands, and the commands are not the same as DOS. Pen, fun, pavilion www. biquge。 info(《》)

Technicians think about problems in a completely different way than the average user, and they think that the command-line approach is much easier to use, more efficient, and more convenient than the graphical one. Therefore, at the beginning, Linus didn't think about graphics at all, after all, the Unix he imitated itself is a system used on large workstations and servers, and using a graphical interface will only take up a lot of CPU and memory resources, which is not necessary at all.

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

In fact, with the popularity of the Windows system, Lin Hong has also been thinking about this question, whether the operating system pursues easy operation, gorgeous interface or performance.

He hasn't figured out the answer yet, but he already has a general understanding, which is why he added a shell to the system in his book.

Of course, this shell is also very simple and somewhat similar.

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

"Yo, how many brothers have arrived? I'm sorry, my little brother is late. Let me introduce myself first, my name is Li Qi and I am from Huainan. ”

As he was talking, he groped a few times through his big pants, and unexpectedly took out a pack of soft China, and each person issued one. From his skillful movements, it can be seen that he is an old smoker.

This fat man is a self-acquaintance, although he has just arrived, but as soon as he said a few words and sent a circle of cigarettes, everyone immediately became familiar with each other, as if they had known each other for a long time.

Of course, this is also related to the deliberate actions of everyone to each other, after all, everyone will be brothers in the same dormitory in the future, and they will spend four years together, and they will always be comfortable when they get along with each other. 《》

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

The four of them were sorted by age, and as a result, Lin Hong found that he had become the boss, he used to be the youngest, but now he became the oldest, which couldn't help but make him sigh a little.

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

"Declare in advance, you can call me Tartar or Zhang Da, or Xiaoda, but you are absolutely not allowed to call the second child, did you hear that?" Zhang Da solemnly declared.

The other three looked at each other and said in unison, "Got it, second child!" ”

After speaking, the three of them laughed, so angry that Zhang Da wanted to beat people, but tragically found that among the four people, he was the shortest and the smallest.

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

He enjoyed the feeling that he had grown up a little incomplete due to his own particular experiences and entered the adult world prematurely.

In the past, he didn't fit in with other people at all, except for a few friends he made when he was studying in the United States, and basically rarely communicated with other people. Moreover, these people are basically much older than him, and their peers cannot communicate on an equal footing.

It wasn't until this moment that he felt like he was truly back in school, and that was the student life he wanted. Innocent and heartless, communicate with each other on an equal footing, without any other distractions.

Having experienced the brutality of war and the baptism of humanity, he has a special experience of this pure friendship.

As they chatted, they talked about girls.

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

"On the way to the dormitory, I saw a girl who was so beautiful that she didn't know if it was from our college. "Fat Li Qi said with a smashing of his mouth.

Zhang Da's eyes lit up when he heard this: "Oh? Is it the one with long hair, about 1.65 meters, with a ** childish face? ”

"That's right! Did you see that too? "Richie felt that he had met a bosom friend.

"I saw it two days ago, it's not from our academy." Zhang Da recalled the situation at that time, "I was shocked when I saw her, followed her for a long distance, and figured out what her name was, hehe! ”

"Holy! Really? "Richie found himself running into a master.

Lin Hong and Wu Dong also realized at this time that they still underestimated Zhang Da's shamelessness.

Zhang Da said proudly: "If I heard correctly, she should be called Su Mei." ”

"Which house is that?" Richie asked.

"I don't know, and the investigation is still to be continued."

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, there must be it in the server of the Academic Affairs Office, and 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 slapped his thigh: "Yes, why didn't I think of it before!" We can hack into the database server of the Registrar's Office! ”

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

As computer science students, they have also heard about this part. Of course, Wu Dong's knowledge was told to him by Zhang Da.

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 understand hacker technology?" ”

The reason why he asked this question was mainly because he saw that Lin Hong was using the Linux operating system, and as far as he knew, the current domestic users of this operating system are all technical masters.

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!" Richie egged.

Zhang Da: "I agree! ”

Wu Dong: "I agree!" ”

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

"That's different, now you're the boss just because you're a little older." Zhang Da saw that there seemed to be a play, and hurriedly said, "Otherwise, I will help you get hot water for another month, and the three of us will each have ten days." ”

The school's hot water room is some distance away from their dormitory, and it is very inconvenient to run long distances every time you get hot water.

Lin Hong immediately agreed: "Deal!" ”

Lin Hong had long planned that even if they knew about this level of invasion, it didn't matter, everyone lived in a dormitory, and sooner or later they would have to let them know, so now take this opportunity to let them have a psychological preparation in their hearts.

Another reason why Lin Hong did this was that he had determined that these three people had good character and were brothers worth dating.

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

The other three immediately gathered around.

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

"That...... Shouldn't you close the door first, it's not good to be seen by others? Lin Hong glanced at the open door.

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

For this level of invasion, Lin Hong can be said to be able to capture it, but he didn't want to exaggerate too much, so he decided to take 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 had learned that Mizuki University was the earliest university in China to have campus networking, which was established as early as 1987.

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

"Before the intrusion, I had to disguise it, so that even if the network administrator found the intrusion, it would not be able to locate our IP address smoothly." Lin Hong explained to them.

"Still doing this?" Wu Dong had never touched this piece before, so it was a little strange.

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

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

"How do you disguise that?"

"Jumps can be made through proxy servers." 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 out, they will see the IP of the proxy server." ”

"It turns out that the role of a proxy server is like this!" Zhang Da suddenly said, "I used to hear other people or magazines talk about proxy servers, but I didn't know what it meant. ”

"Proxy servers can be used for many purposes, such as controlling access rights, controlling the length and amount of time spent online, and acting as a firewall, becoming a conduit between the intranet and the Internet, and so on. For example, if our computers want to access the Internet, they have to go through a proxy server in the network center, and they can monitor what websites the whole school is on on the gateway server. ”

"Huh? Can they all see? Zhang Da was stunned, he obviously never knew about this situation, "If I go to some foreign websites...... Adult sites that they can also discover? ”

Lin Hong was speechless: "Of course." ”

At this time, Wu Dong interjected: "In this way, wouldn't it be pointless to use a proxy server to invade?" ”
