My friend arrived at two o'clock in the afternoon. I told him that my uncle needed him to help check the computer. The cost was 100,000 yuan. This guy is short of money, so he gets up at five o'clock and a plane arrives.
I told him that I would not come to him if I had something to do, and let him earn the money steadily.
This person is a classmate of mine. He has some skills on the computer. Last time I checked that website, he also helped.
As soon as I told him my request, he immediately understood it, and did not ask why, so he started the whole process immediately.
But he just moved the entire computer, took a look, and said "Huh".
I asked what was wrong, and he said: "Your computer is not connected to the Internet."
"No internet connection?"
"Look, there is no network cable."
I went down to take a look, and was stunned. Sure enough, there was nothing behind the computer, even a person like me with little computer knowledge can be sure.
There is absolutely no network cable connected to this computer, because it has only one power cord connected to the socket.
"wireless network?"
"Impossible, there is no wireless network driver system installed in the computer."
"Then what's going on?" I wondered.
I rely on. This is GHOSTNET, I said to my heart. I have seen a computer in a TV show before that it can be connected to another computer in another world through some kind of spiritual power. The people inside said that this kind of network is called "ghost network".
I don't know the principle, but it will definitely not be a ghost net. I suddenly realized that this matter is very important.
I sat back in front of the computer and calmed down. He said: "I have to take a look at it to know what's going on, otherwise, you are talking to yourself."
"I don't understand, you should be more specific."
"Theoretically, this can also be done. Two accounts can be set up in one computer and communicate with each other in the same computer."
"No need for internet?"
"No, but is there any actual content in your email exchange?"
I nodded: "Of course there is."
"That can't be the case, I think there must be something strange in the case." He said.
I asked him if he would damage the machine, and he shook his head and said absolutely not.
He was very fast. Obviously he was used to installing computers in the Computer City. He quickly removed the shell of the mainframe, which was full of circuit boards that I couldn't understand.
He knocked it inside with tweezers. After reading it, his face was pale and he said to me: "Uncle, this is really fucking weird, there is no network card in it."
I don't understand how serious this is, showing a puzzled look.
He said: "On the computer level, this violates the laws of physics.
If you don't have a network card, it is absolutely impossible to receive mail from any external network. Impossible, the email you received can only come from your computer itself. "
"What's the meaning?"
"Either you are sending emails to yourself, or your computer can send emails to you."
I shook my head, this is absolutely impossible. "Absolutely impossible, you take a closer look." I said.
Suddenly I remembered the last e-mail from yesterday. Damn, is this computer wise? It saw me smoking cigarettes in this room instead of monitoring my balcony somewhere else here
There was a chill in my body. If this is the case, are our actions now raping it? No, dissect it.
I quickly dispelled this ridiculous idea. There must be something strange in this. My classmate continued to study the inside of the case. Suddenly, he gave a "Huh", shone a very thin white wire with a flashlight, and said, "That's it."
"What's the reason?" I asked impatiently. He said: "I don't know yet, but there is a strange wire here."
He pulled away the white wire, which was very thin. He touched it all the way to the source of the wire, which was connected to the computer's power supply.
He immediately disassembled the power supply. After removing the power supply, he picked out the white wire with a screwdriver and found that the wire was connected to a small electronic component.
I couldn't understand at all, watching my classmate touch his chin.
He thought for a long time, then said: "I can't believe what I saw, I would actually see this thing in this era.
You may not understand what I said. This is a very primitive network card, which uses the ground wire to transmit signals. This is a peer-to-peer network, and the other party's computer is only connected to your computer. It is actually a Morse cipher parser. "
"Where is he?" I don't want to know how it works.
"I don't know. The ground wire of the power supply he uses is a special circuit. Do you have a circuit diagram of this house? If so, I can find it out for you."
I shook my head. Needless to say, I didn't know where the thing was. Even if there was this thing before, Sanshu must have destroyed it. With the prudence of the Three Powers, it is impossible for him to allow the possibility of exposing this line to exist.
He said: "The only way is to pull out this line. One end of the line is here, then the other end can be found by just looking for it along the line." Then he pointed to the socket embedded in the floor, "Here is The source. We have to pry open the floor and find the direction of this line. Another computer must be connected to this line."
I thought for a while and told him not to act rashly. I have to think about it, if there is too much movement, people will find it, and it must be done lightly. He said: "This kind of private network has a short transmission distance, and it is impossible to leave this house too far, otherwise it will involve the street transformer on the side of the road. Therefore, his location must not be too far from here, it must be in a few places. Within a hundred meters, you will be able to find out soon."
"How long do you think it takes at most?"
"You can find it in up to three hours."
I patted him, and said, "In this way, you take a break first, and we will wait until dark at night before getting it. You first install the computer for me."
The situation continues to change and needs to wait until the next hour.
This is an email from me. Let the person wait. In this case, this man will always wait by the computer. If I can find it, I can break the door and grab a current one.
The other party never replied. I waited until it was completely dark, and then asked my classmate to start work with a cloth-wrapped flashlight.
Uncle San’s house was actually remodeled from an old farmer’s house. All the lines were open lines, but Uncle San added a layer to the ground for safety.
After carefully prying the floor open, my friend broke the protective shell outside the protective wire and pulled the wire out.
I ran to the second floor to see which one of the external wires on the roof was pulled.
Then I searched it all the way and found that this wire was directly connected to the outside of the house. I pulled out all the rivets fixing this wire and continued to make my classmate twitch.
On the first floor, we followed this wire all the way forward and came to the courtyard. Then, we saw the wires go straight down, all the way to the underground.
I was surprised that the third uncle’s yard was small, only six or seven square meters. There were four or five wires in the bundle, all running under the eaves of the wall, and only one wire went underground.
The ground is full of messy potted plants, there are more than a dozen pots. My friend and I carefully moved away one pot after another, and I was surprised to see a manhole cover.
The wires went all the way down and went into this manhole.
I never knew that there was still this thing in San Shu's house. There was a handle on the manhole cover. I went up and lifted it, and found that it could be lifted. It was dark inside, and my heart hung up.
There are doors.
I took a breath, and said to my classmate: "Okay, just get here." After taking him away, I immediately went to the house to get a flashlight, came to the manhole cover, and took a deep breath. , Pull it up and take it down.
