Reborn Ace Hack

Xiao Yuan kept the manuscript of the introductory article about Linux. After finding the manuscript, he briefly browsed it, corrected some typos and some language inaccuracies, and added some content about GNU.

, expanded the article content from 5,000 words to more than 8,000 words, then created a new post called "Introduction and Introduction to the Free Software Movement and Linux", and then posted the article.

After the post was posted, Xiao Yuan withdrew from the Lenghuo forum. At this time, it was only around eight o'clock in the evening, which was still early before he was used to going to bed, so he opened vi (a commonly used tool under Linux or Unix).

text editor) and started working as planned.

The first thing he designed was a set of firewall suites. The firewall he used himself, Xiao Yuan did not intend to design it into something as large and comprehensive as the Xuannie firewall, but completely followed the design philosophy under Unix (there is a book

, called Unix Programming Art, if you are interested, you can check it out.) It is designed as a set of tools that can work both jointly and independently, thereby ensuring that the system consumes the least system resources.

With maximum flexibility and security.

If the Xuanni Firewall is compared to a solid wall of a city, then the firewall he wants to design now is like the armor on a soldier's body, the shield in his hand, and a long knife. It can be used for both attack and defense.

.

In fact, the best environment for running this toolset is a small distributed computer network, including three to five computers. Xiao Yuan even thinks about using one machine specifically to design a honeypot system in the future.

But now he only has two computers, and his main task now is the college entrance examination, not this, so the idea that once appeared in his mind was quickly abandoned by him.

Xiao Yuan first designed a system shell. The so-called shell is actually a daemon process that resides in memory. All network data entering and leaving his machine must first enter this shell and be analyzed by the shell's analysis program. If

If the shell thinks it is legal, then it will release the data packet and let it enter the system. If the data is illegal, then the shell will discard the data packet. At the same time, based on the characteristics of the data source, it will further judge whether the data packet is

The source IP is processed.

The core of this shell is an intelligent judgment program for the legality of data packets. This judgment program is the focus of Xiao Yuan's design. Here he still uses a technology obtained from blackskull in his previous life. This technology is compared to the Xuannie firewall.

The intelligent core is much more advanced, because this is a technology that only S-class members have the opportunity to see, and this technology is also available in blackskull

It only appeared in 2005, so Xiao Yuan believes that this technology is definitely beyond the era in the parallel time and space in which he was reborn, and he is definitely the only person in the world who has mastered this technology.

Concentrating on programming is a kind of enjoyment for Xiao Yuan, so time passes quickly. If Yang Jingchen hadn't come over and interrupted his train of thought because he was concerned about his physical condition, he would have almost completely forgotten about time.

.

Before going to bed, Xiao Yuan logged into the Lenghuo Forum again, checked his post, and found that there were many comments on that post. His user experience increased rapidly. He had reached level six and was about to reach level seven.

Level.

"Haha, it seems that the level increases faster after posting new posts."

Xiao Yuan was very satisfied with his current level growth. He thought with a smile, opened the post and looked through the comments below. Some were trolling, some were discussing his post, and several people asked him questions.

Yes, he answered a few questions, then exited the forum, turned off the computer, and went to bed.

…………

The next day, he was still recuperating at home. During the day, he did not touch the computer again, but devoted himself wholeheartedly to studying high school courses. He still knew the saying that learning is like sailing against the current. If you don't advance, you will retreat. So he didn't

Dare to relax even a little bit.

At noon, Lin Ran brought news to Xiao Yuan that Liu Wenwen had really transferred to another school, but he never went to school and was mistakenly thought by many students that he had transferred.

Xiao Yuan couldn't laugh or cry about the rumors that he had transferred to another school, but he didn't take it too seriously. Rumors were just rumors after all. When he returned to school again, all speculations and misunderstandings would be disproven.

Tang Sa has never visited Xiao Yuan since he was discharged from the hospital. Xiao Yuan secretly speculated that it was probably the reason she said when she sent him back that night that they would see less of each other in the future.

But since she said that they would see each other less often in the future, when he was in the hospital, she took care of him in the hospital for so long. Xiao Yuan understood why Tang Sa did this, and couldn't help but feel a little emotional and helpless in his heart.

Can leave a slight sigh.

At night, after studying for a while, Xiao Yuan turned on the computer and continued writing programs. It was not until almost early in the morning when his mother urged him to sleep again that he logged into the forum to see the replies to his post.

.

After he entered the forum, he didn't see his post on the homepage, which made him feel a little strange. According to the popularity yesterday, there was no reason for it not to be on the homepage, so in order to quickly find his post, he entered his personal center. There was a name in the personal center.

It is the management page of 'My Posts', where you can find all the posts you have posted.

But when he opened the 'My Posts' management page, he found that it was empty and his posts were missing.

"What's going on?" Xiao Yuan frowned, so he entered the message center to check, and found a system message that surprised him. His post was deleted. The reason for deletion was that someone reported him for plagiarism.

After verification by the moderator, he deleted the post and cleared all the experience points gained from the post. Only then did he discover that his forum level had dropped back to level five.

"Am I plagiarizing? "Report me for plagiarism?" Xiao Yuan thought to himself, "Judging from the selfishness that guy showed yesterday, it is really possible that he did it, but it is best to confirm it to avoid unjustly accusing a good person."

The message did not mention who reported him for plagiarism, so Xiao Yuan decided to use the moderator contact tool provided by the personal center to contact the moderators of each section of the forum to ask what was going on and who was reporting it.

He plagiarized.

After the message was sent, Xiao Yuan wandered around the forum for a while without waiting for the moderator's reply. It was almost early in the morning. He thought the moderator had taken a rest, so he quit the forum and went to bed.

The third day was Xiao Yuan's last day to rest at home. His body had completely recovered under the traditional Chinese medicine prescribed by Yang Shancheng, so he resumed his previous morning exercises, only slightly reducing the amount of exercise.

After breakfast, Xiao Yuan returned to the room again and studied all morning. After lunch, he turned on the computer again, entered the forum, and directly entered his personal center. He wanted to see what the forum moderator had given him.

reply.

"Sorry, your permission is too low and you cannot contact the moderator. Your request has been rejected."

This message made Xiao Yuan frown again. Judging from the wording, it looked like an automatic reply from the system. However, Xiao Yuan felt that there were some problems with this reply. First of all, if his authority was too low, the system would automatically reject it.

His request should be responded to in a timely manner, but yesterday he clearly waited for a while and still did not see a reply. Is it possible that the forum server is already so busy that even automatic reply messages are delayed for several hours? This is very unreasonable

.

Secondly, in the forum's level permission list, there is no restriction that the permission is too low to contact the forum moderator.

"It's paralyzing, it's probably the moderator who is up to something." Xiao Yuan cursed secretly after some analysis.

"You think my level is too low, right? Then I will raise my level. I hope you will follow the rules when the time comes, otherwise don't blame me for being rude."

Xiao Yuan endured the anger in his heart, and finally suppressed the urge to invade the cold fire forum. He decided to follow the rules first. At the same time, he also decided that if the moderator still did not follow the rules after he upgraded his level, then he would

It is necessary to have a conversation with hotfire, the chief moderator of the cold fire forum. If hotfire still can't solve the problem, then I'm sorry, he will be ready to rely on his own efforts.

Because of the anger in his heart, Xiao Yuan stopped reading and spent the whole afternoon on forums to gain experience.

He still chose to answer questions in the Q&A area. From a little past 1 p.m. to 5 p.m., for several hours, he answered a large number of questions. This almost crazy move soon caused a stir in the Q&A area.

Some people's attention.

There was a guy who was bored. Starting from two o'clock, he counted the questions answered by Xiao Yuan every hour. He found that this guy with the ID name ghostyx could solve more than a dozen questions in an hour, with an average of five or six.

One question can be solved in minutes. The answering speed is astonishing. Moreover, many of the questions chosen by ghostyx are related to the in-depth application of the system, which are difficult to answer. The solutions are by no means plagiarized from above. Some of the solutions are

It has never even appeared on the Internet.

"A maniac has suddenly appeared in the Q&A area. Come and watch, everyone?"

So this guy posted a post like this on some of the most popular sections of the forum at about four o'clock in the afternoon, and wrote down his statistical results in the post. So some people who saw it, out of curiosity,

I entered the Q&A area and took a look, and found that it was indeed the case. That’s it.

, the news about the madman appearing in the Q&A area spread like wildfire in the forum, instantly attracting countless people to watch, and there were many more people asking questions than before. As a result, the traffic in the Q&A area soared instantly, and even

It once became the most popular section of the Cold Fire Forum.

Xiao Yuan had been concentrating on answering questions, and trolling was not allowed in the Q&A area. Therefore, he just felt that more and more people were asking questions later, and he was not aware of the news that his reputation as a question-answering fanatic had spread in the forum.

At five o'clock in the afternoon, Xiao Yuan stopped answering questions and prepared to enter the personal center to check his level. Then he sent a request message to the moderator of the deleted post, asking him to tell him who was reporting him for plagiarism.

.

After entering the personal center, he found that there was a new message, so he entered the message page, but was shocked by what he saw.

"When did I become a piece of cake?!"
