Bit Mania [Hacking]

"The so-called Internet is like a big house, with countless doors leading to all parts of the world. Once people get permission, they can enter this room through different doors and communicate with other people from all over the world. When this house When it's big enough and organized, it can hold every computer user in the world..."

"Of course, if all kinds of things can go in, the room will soon be messed up, so the concept of Internet Protocol is proposed, which is a set of unified standards, just like only two-legged people can go in. Keep cats and dogs out..."

"And what about the gorilla?"

"Well, then you have to add one more, only those with no hair on their face can get in..."

"What if the hair on the gorilla's face is shaved?" Another student asked below: "What about a man with excessive hormone secretion, teacher?"

"..." The old academician Song Yubai twitched his eyebrows, and said with a straight face: "If that gorilla has such a high IQ, then we can't racially discriminate against it! If the beard grows crazy, please ask him to have a ligation Come again!"

There was laughter from below.

"Enough, you little bastards, what did you say just now?"

"Speaking of ligation teacher."

"... Can adding a punctuation mark kill you?!" The old academician was so angry that his beard trembled: "Continue to talk about the Internet! The Internet is the largest wide area network in the world. It connects local area networks and computer systems distributed all over the world. Connected, we need to connect now, we must first integrate our local area network, make it compatible with the Internet protocol, and then punch a hole in the house of the Internet, so that we can freely enter and exit, what I said above, It's all basic theory... Luo Zixin!"

Someone who was enjoying tinkering with the computer raised his head blankly: "Huh?"

"I now appoint you as the chief engineer, and you will lead the team of 27 people present to complete this arduous mission!"

As soon as the words fell, the disciples were in an uproar: "This, is this too hasty? We thought that the teacher would lead the team personally..."

"Don't you guys still trust this little guy's level?" The old academician raised his eyelids and looked at everyone.

"That's not true," someone said. "It's just that if the guys who guard the Internet switches in the United States know that the first team connected to the Internet in our country was led by a child...they will cry."

Old Mr. Song said with a smile: "I want them to cry, not only to cry, but also to cover their faces and cry, roll all over the ground and cry, hugging into a ball and crying!"

"... Teacher, you are too bad!" These young people in their 30s and [-]s smirked and rubbed their hands.

Zixin looked left and right, completely unaware that he was being coaxed by some excess energy to do something stupid.

After planning this conspiracy, everyone gathered together to start a strategic deployment. After a little thought, Zixin divided the staff into four groups, ranked from high to low in technical difficulty, respectively transforming the network topology, modifying the original security policy, Protocol compatible and batch processing.

The transformation of the network topology is related to the placement of hardware equipment. Zixin led the group to discuss several plans. A master student was beside them quickly recording the content. After finalizing a plan, everyone breathed a sigh of relief and took I went to show Mr. Song, but I didn't expect that the old man was lying in the rocking chair beside him, sleeping soundly, snoring loudly, and looked detached. Seeing his attitude, everyone stopped counting on him and took the set plan Start to overcome other technical difficulties.

That's why the old academician didn't know in time that he slept like a sleeper.

The day passed quickly, and everyone hadn't really put it into action, but the theoretical planning had made a great breakthrough. This was also because Zixin's solid basic skills played an important role. Unlike other people who studied computers, he was very familiar with computers. The most basic principle of operation can be said to be clear in the chest. Because of familiarity with the principle, it is often possible to propose ideas from the most fundamental things, so that everyone can avoid a lot of detours, and also have a deeper understanding of the old man Song Yubai who asked Zixin to be in charge. The purpose of the general plan.

Some people, as long as they get along with him, can be shocked by its value.

After dark, all the people dispersed, and Zixin went home, sorted out the various programs he had written into the laser, and brought this gadget to Lao Song's house the next day.

"This, this, this, this...is this the computer you were using before?!"

"Yes." Zixin nodded, bypassing the surrounding seniors, and connected the LASER with the new computer to share resources.

A senior doctoral student stared blankly at his series of actions, and after a long time turned his head stiffly and said to the people around him: "Don't tell me that he just used such a claw machine that cannot display graphics to beat me with a graphical interface program written in Pascal. of……"

"Who said it can't display graphics?" Zixin retorted unconvinced: "Look."

He typed a few commands on the keyboard, and the black and white TV set in front of him made a buzzing sound. Someone impatiently punched the snowflakes on the screen, and the TV set, which was not much bigger than a palm, trembled. A set of the latest version of the Pascal interface is displayed.

Such a situation is like a wretched big yellow mouse suddenly ran up to you, blinked its big eyes and called "Picka~~Qiu", and then released a hundred thousand volts of high voltage electricity to turn the dinosaur into slag.

A gust of wind blew by, and everyone stood there with their noses running, speechless for a long time.

Zixin ignored the group of stone sculptures, packaged and uploaded the programs on the LASER to the new computer, and then modified them according to the new operating environment so that they could be used normally on the new computer. There are many programs, and modification takes time , while he put two computers there to transmit, he continued to discuss yesterday's unfinished project with his brothers and sisters.

One of the seniors wrote down their plan yesterday, went back and transcribed the structure diagram overnight, and now he showed it to Zixin. After reading it, he nodded with satisfaction. The structure has already taken shape, and the next step is the issue of safety.

To put it simply, when you buy a computer home, it will come with a set of protective measures to prevent malicious intrusion and keep privacy. It can be a hardware firewall or a user rights management system. These things, but they are the control imposed from the authority, which is the most basic and indispensable layer of defense against intrusion.

Just like a person walking on the street, he may not be wearing a bulletproof vest or a helmet, but he must wear at least one pair of underpants, which is already a matter of dignity.

Oh, so what we have to do now is to secretly take off the guy's underpants without the other party realizing it, and then replace him with a new pair. This is an essential step in the integration of the network. Why? What about changing pants?Because that person was only walking on land, now he is going into the water, so the pants must also be waterproof... And the objects we want to strip the underwear here are all the nearby computers that they want to integrate, not just these few Ten people's own, as long as they are within the scope, they all need to be modified.

Time passed quickly in the midst of running around. Zixin and his group had to implement the plan by themselves. First, they approved a bunch of equipment from the teacher, and then ran around under the confused eyes of Mr. Song, sometimes even I ran to the nearby university town to negotiate with people, and no one touched the ground.

Protocol compatibility and batch processing are relatively easy. There is no difficulty, but the workload is heavy. Zixin entrusts other people to do the work. After three months, everything is ready in the blink of an eye, and only Dongfeng is missing.

At the end of July, the hottest day of the year, the scorching sun shines through the windows and transforms into diamond-shaped light into the house. Some people are afraid that the temperature of the computer will be too high, so they go forward and close the curtains.

The room was dark, the beige curtains made the room dark yellow, and the Internet connection was finally completed. Everyone was sweating and huddled together, but they were very excited. All the hardware and software had been checked. Zixin picked up someone's folding fan next to him and fanned himself twice, driving away some heat, and then pressed the last button under everyone's expectant eyes, the data stream passed through the router, satellite signal, It was transferred to the Internet exchange switchboard in the United States.

The huge amount of information surges in like a tide that has opened the floodgates. This is the power of the world's largest wide area network. Compared with the libraries and government intranets that Zixin has come into contact with in the past, it can be said to be the difference between dinosaurs and ants.

Three months of hard work has finally borne fruit. Except for a small number of brothers who have studied in Europe and the United States, most of them have seen such a vastness for the first time, and they were deeply shocked without exception. , cheered and looked around curiously.

"Good job." Elder Song watched from the side with a smile, and praised without hesitation: "Although the network bandwidth is low and the Internet is not stable after borrowing the authority of the foreign exchange, you have already taken an absolutely meaningful step. , after your success, our entire Huaguo Union will be connected to the Internet, and it will be just around the corner."

Zixin was still enjoying the teacher's praise at first, but when he heard it, his face was a little embarrassed: "We don't have permission to borrow from abroad..."

"Huh? Then how did you connect?"

"Register the authority of our own country."

"..." Mr. Song's eyes were dull: "This, this is impossible, our network is so small, how can we pass the certification?!..."

Zixin touched his nose: "Oh, we have integrated all the areas with a radius of [-] kilometers around Huanjiang Town, including the three universities in Quhai University City. With the addition of their campus LAN, the scale is sufficient It's..."

Listening to what he said, Elder Song clutched his chest and heaved violently, his breathing was unsteady.

"Teacher Song, what's wrong with you!" "Don't scare us!" The temperature has cooled down, and some people have searched for panacea.

"You you you you you!..." The old man waited for a long time before pointing at Zixin's nose and cursing viciously, "You brazen little bastard..."

"I actually registered Huaguo's official Internet authority occupation... Alas, alas! This small place in Huanjiang Town is about to become the core of our country's network exchange... It depends on what you do..."

With a bitter face, Zixin asked nonchalantly: "Then what should I do, teacher? How about I go and cancel the authority?"

"Is that something that can be canceled casually?...Little monster, there is only one thing you can do now."

"what's up?"

Elder Song finally couldn't hold back a smile on his face: "Stay here tonight, everyone will have a celebration party! I will report this matter to the central government and resolve it according to their wishes. Don't worry, you little bastard!"

……

After tossing with joy and tears, the old man soon became too tired, so he went back to his room early to rest in order to recharge his energy and have a good time at the party. Zixin sent the man to lie down in the bedroom, and then returned to the living room , officially began to explore the Internet.

He tried to visit several world-renowned hosts, when a pop-up window popped up on the computer, he paused, and after confirming that the request was not malicious, he clicked Allow, and watched a piece of software being installed on his computer, The software is very simple, it loads and runs in seconds.

A small box appeared on the screen, along with a line of words.

Elmo: Hi~ I'm Qi Xingchu.

He was so frightened that he almost fell off the chair. With a shake of his hand, he subconsciously threw a logic bomb over.

After the bomb was sent out, he knew that his hand was shot, and the other party fell into silence. About 10 minutes later, the firewall suddenly let out a huge roar, which meant that someone had launched an attack on it!Zixin quickly set up the defense program to resist the attack from the other end of the network.

Today's computer is no longer the same as Octopus LASER. During the days of planning to connect to the Internet, he is constantly improving this new computer. The computer is the operating system of Amiga. The reason why he chose this at the beginning is because of the importance. It is flexible and variable, can run many more applications than systems such as Win3.0 launched in the same generation, and has a high response to the outside world. It is the most advanced real-time operating system today. As a result, Whether it's computing speed or system resources, the hardware configuration of the world's top civilian computers was already in the first place. In addition to his transformation during these days, none of the senior brothers could successfully invade the system of this computer.

So Zixin is very confident in himself, but he does not dare to underestimate Qi Xingchu. He still remembers the scene where the other party killed the library firewall into pieces with only a calculation of more than 200K data packets.

Sure enough, Xingchu's attack method is very characteristic. Through the in-depth understanding of the defense system, he compiled exquisite instructions to achieve the purpose of capture.

Speaking of which, Xingchu's ability is actually more comprehensive, whether it is attack or defense, he has extremely high attainments, but if we really want to analyze this person, the conclusion is still more superb in defense, because he is in They often have reservations when attacking, and to put it bluntly, there is no murderous intent.

Just like the knights in ancient times, when fighting with others, they won by confiscating the opponent's weapons, and put the sword on the opponent's neck, but they did not want to see blood.

Zixin is better at slanting his sword. When he is not attacking, he is like a feline lurking in the grass. Once he finds the opponent's weakness, he will use all his strength to launch a thunderous blow. But when it comes to defense, he is It's not as good as attacking.

After fighting hard for four hours, Zi Xin pinched the sword around his neck with two fingers with a dry smile, and moved it back quietly.

Octo: Okay, Brother Xingchu, long time no see, talk to me if you have something to say... (How can he be so powerful?!)

Someone on the other end of the network twitched his mouth, ignored the little guy's behavior, confiscated control of the other party's computer, and smashed programs with malicious damage functions in Zixin's computer one by one, and finally set a prohibition on recovery.

Zixin knew he was wrong, so he could only yell at the side, Octo: ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!

In the pleasant background sound, someone released the control of the computer, just about to speak, but suddenly received a remote letter on the communication software.

Israel: Qi Xingchu, you are indeed reborn.

Xingchu's face suddenly became extremely dignified.

Elmo: It's you!

What he answered was a never-before-seen worm virus, which was thrown onto the network like a nuclear bomb. Before he could stop it, a large amount of junk code had already replicated itself at an astonishing speed through mail and WEB servers.

Elmo: This is it? ! ...

Israel: Octo's unpublished relic, its name is "Bright as Day".
