As usual, Long Dan received the painter during the day, arranged the company's affairs, and then it was time to chat at night. Since his father's death, Long Dan went to the chat room again, and he didn't need to call the name Chungui, and gave him a "cat's eye to see the world" network name, Long Dan raised his own cat's eye to see the world to the highest level, which can not only be invisible, but also kick people, and can also give others extra points and upgrades. Soon, though, the name became known to belong to the chat room administrator, because all the information about this name was invisible to anyone. In a chat room, people with a high level can see the registration information of people with a low level, which makes the rules of the game designed by the room designer.

On this day, as soon as Long Dan entered the chat room with "cat's eyes to see the world", a person with a level second only to him came in. This person's screen name is very special called "but so", but it is so crazy, rarely chatting with people, and if others are slightly disrespectful, they will kick others out of the chat room. There have been many people who have complained about Long Dan's name "cat's eyes to see the world". Long Dan didn't know what was going on, so he carefully observed this "but that's it".

Long Dan's surveillance uses the secret check function, that is, you can see all the chat records of the chatter, whether you are public or secretly talking, under the secret check function, there is nothing to hide. I saw "but that's it" chatting with a screen name called "Drunkard's Meaning".

But that's it: "Mr. Drunkard, how about the level I gave you?" When are you going to invite me to dinner? The drunkard said: "But Mr. is really stingy, just mentioned to me level 18, just can kick people, not much meaning, as long as you can give me a commission of level 24, what kind of hotel you say, I am willing to accompany" But so: "Mr. drunkard, it's not that I don't mention it to you, it's just that I can't mention it to you too quickly, and it's easy to be discovered by the administrator if it's too fast." Once you find out, you'll be banned, and I'm afraid I won't even have my name at that time", the drunkard said: "Even if I believe in you, but, I ask you to, you have to promise me a commission of level 24, but I told my girlfriend, you must get this level 24 name, she is good to be in the chat room", the two said here, but so it went offline.

When Long Dan saw this, he couldn't help but be surprised: "Isn't he the highest authority?" In the chat room, it's clear that only you can add points to the promotion, why does it come out with a 'but so'? ”。 The next day, Long Dan dialed the phone of Zhang Rong, an old classmate of the information port of the communication company, and told him what he saw in the chat room, Zhang Rong said: "Old classmate, I don't know how you learned computer knowledge in college, and you don't even understand this?" Long Dan said self-deprecatingly: "The simple ABC language I learned in college is very simple, and I have already returned my knowledge to the teacher for more than ten years, not to mention that I am not a computer major, how can I compare to you." Zhang Rong said: "To put it bluntly, it's worthless, it's true that only you are the highest level in the chat room, and no one else can be promoted to add points, except for one case", Long Dan asked eagerly: "What's the situation?" "Hacker" Zhang Rong replied briefly.

"Hackers? What hack? You have to tell me about it" Long Dan didn't understand what a hacker was, Zhang Rong said: "When do you have time to come to my office, I'll tell you about it, and I can't tell you clearly on the phone for a while." However, we have a way to deal with hackers, as long as the server is restarted, all unauthorized modifications made by hackers, the system program will be automatically removed, you don't have to be afraid of them making trouble".

Long Dan immediately went to Zhang Rong's office, and Zhang Rong talked about it from programming to hacking. Long Dan roughly understood what the "but that's it" thing was doing.

It turns out that the matter is very simple, that is, "but so" is a programming master, taking advantage of the loophole of the chat room program, invading the background management system of the chat room, imitating the highest authority of Long Dan, and modifying the permissions of some screen names.

Long Dan understood the principle and returned to his office. didn't let Zhang Rong restart the chat room server, and erased the number of "but so" modifications. Do it yourself, operate it manually, and reduce the level of "just so" from level 24 to level 3. Because you can only talk if you are above level 3, if you downgrade him to level 1, you will not be able to talk to him.

Sure enough, at night, Long Dan used the screen name "Cat's Eyes to See the World", and as soon as he entered the chat room, "But so" came up.

But that's it: "Mr. Cat's Eye, did you downgrade my level to level 3?" The cat's eyes look at the world: "Naturally it's me, do you want anyone else?" But that's it: "Mr. Maoyan, it's useless, I'll still raise my level", Maoyan looked at the world: "But sir, you're useless, I'll block your IP, even if you use a proxy address, I've locked your home address, isn't it?" Mr. Ge? But so: "You know me? Maoyan looked at the world: "Hahaha, it's not that I know you, it's the system that automatically locks your real IP, your computer is registered in a communication company, and you can have your ID card." What do you think? Mr. Ge Jiawei? ”。

"Damn, you can't lock my computer, so can I still access the Internet?" I'm going to complain about you," he said angrily. In fact, Long Dan's knowledge is also now learned and sold, and he just learned it from his old classmate Zhang Rong. However, it really worked, and the immediate "but so" was angry.

"Damn? Who do you rely on? If I go to the Internet Supervision Brigade of the Municipal Public Security Bureau to report the case, I will detain you for at least 15 days. I'll report the case tomorrow, so do you still complain? Long Dan said proudly. But he immediately said: "Don't be there, I said Maoyan brother, I'll invite you at the Luzhong Hotel tomorrow, don't report the case, I'll be done as soon as you report the case." Long Dan couldn't see that he was so convinced, and he wouldn't really report the case, because after all, he invaded the chat room, and the chat room was a place to chat, and there was no such thing as zài's infringement, so the matter could be completely ignored. Long Dan agreed to such a request, and went to the appointment as scheduled the next day, and came to the lobby of the Luzhong Hotel, according to the agreement, Long Dan took a copy of the "Money World" magazine, sat on the sofa in the lobby, and waited for the arrival of the hacker.

Long Dan waited for a long time and didn't see the arrival of the "but so" hacker, seeing that the time for dinner had passed, he stood up a little angrily, walked out of the hall, opened his car door and was about to drive back. At this time, a young man with sunglasses appeared from the side and said, "You are the cat-eye brother, right?" "What cat's eye brother, my surname is ......" Long Dan immediately remembered that he might be nothing more than that, so he asked, "Ge Jiawei?" The person who came nodded vigorously and said, "It's me, I'm sorry big brother, I'm late, please come inside" Long Dan followed Ge Jiawei to the private room that had already been booked.

Long Dan watched Ge Jiawei take off his sunglasses, and said teasingly: "I said that your kid has come a long time ago?" Ge Jiawei saw Long Dan say this, so he said embarrassedly: "I'm afraid that Big Brother Cat brought the police" "What Big Brother Cat, am I a cat?" My surname is Long" Long Dan interrupted Ge Jiawei's words and said: "If you are arrested, you still need to be so troublesome, you will have to go directly to your house", Ge Jiawei said with a smile: "What Brother Long said is, I'm not cowardly" Long Dan smiled: "You kid, you still claim to be cowardly, today you can invade the information port chat room, who knows if you dare to invade the bank tomorrow" "Brother Long, don't scare me, I will never dare to hack into the bank, besides, can Yinhai's system have so many loopholes?" Ge Jiawei hurriedly said.

"You say there are a lot of loopholes in the Infoport chat room? What's going on? Long Fan also asked curiously, and Ge Jiawei said: "The chat room in the information port is not full of loopholes, it is simply a broken sack, and there are loopholes everywhere. Maybe the person who designed the chat room didn't think that someone would be bored enough to invade a chat room, so when designing it, he didn't work on the firewall at all", Long Dan understood when he heard it.

"You learned to code? That college graduate? Long Dan asked, Ge Jiawei hurriedly said: "The computer science department of Qilu University, just graduated last year, because he didn't find a suitable job, he did some odd jobs for others at home, and ate a lot of food." When Long Dan heard this, he said: "We are still alumni, I am an 80-level student, but I am studying management" "We are still alumni, you are an old-timer, now it's easy to say, I said Brother Long, we are a family" Ge Jiawei became energetic when he heard it, and said loudly.

"What odd jobs do you usually do for others, won't it also hack into other people's systems?" Long Dan asked, Ge Jiawei hurriedly said: "That's okay, I just make some websites for others, and I earn thousands of yuan every month, which is much better than going to work" "Can you make a website?" "Yes, making a website is my forte, no matter what kind of website, as long as I look at it, I can immediately imitate it, of course, I also have my own creativity, not all imitation", Long Dan listened to Ge Jiawei's words and couldn't help but think deeply.
