Five Hundred and Forty-Two. Action

"Fortunately, I should be fine after a few days of rest." Wang Zhitao said with fear.

"Well, I happen to have nothing to do these days, so I came over to stay with you..." Zhou Jiajia said.

"Okay... great, thank you, Zhou Jiajia." Wang Zhitao said with some emotion: "You should treat this place as your own home. I can't get out of bed now, and I'm still very weak, so I can't get up to entertain you. …”

"It's okay, just take a good rest." Zhou Jiajia nodded: "Do you want to eat fruit? I'll get you one?"

"No need... the injection I took this morning contained hypnotic ingredients, so I'm a little sleepy..." Wang Zhitao yawned as he spoke, and said, "I'm going to take a nap first... There is a TV in the living room , you can go and see..."

"Okay, then you can rest." Zhou Jiajia smiled sweetly and said, "I brought my notebook, so you don't have to worry about me."

"Okay..." Wang Zhitao nodded and closed his eyes.

Zhou Jiajia quietly walked out of Wang Zhitao's bedroom and closed the door for him. After waiting for a while, I felt relieved when I heard a slight snoring coming from Wang Zhitao's room.

Zhou Jiajia came to the living room, first took out a small instrument from her computer bag, adjusted the frequency and started scanning. Generally, many wealthy people like to install monitors and the like. Zhou Jiajia was not sure if such a thing existed in Wang Xifan's home, so she had to be careful.

Fortunately, the test results showed that there was no monitoring system installed in Wang Xifan's home. This may also be because there is a nanny at home, so it is not easy for thieves to break into.

Zhou Jiajia breathed a sigh of relief, connected the computer to Wang Xifan's home network with a network cable, and looked at the IP address obtained by the computer. It was a LAN IP segment of 192.168.1.X.

I used software to scan the computers on the current LAN, but no other clients were found. It seems that they are not turned on. So Zhou Jiajia got up and went to the study upstairs. Fortunately, the door of the study was not locked. It seemed that Wang Xifan did not guard himself.

Zhou Jiajia listened carefully to the movement in the corridor, and then quickly came to the writing desk. Opened the computer on the table.

There was a clear "di" sound, and the screen stayed on the startup screen:

I actually set a password for the motherboard! This was the password that gave Zhou Jiajia the most headache. Zhou Jiajia casually typed Wang Zhitao's birthday, which was wrong. I typed Wang Xifan's name again, but it was wrong. I tried a few more, but still got the error.

This password is not like a system password.

If it is the password of the operating system, you can directly use the PE system to boot, bypassing the original operating system, but this password does not work, it cannot be detected, and the system will not start at all!

Zhou Jiajia had no choice but to remove the hard drive! Although the password can be cleared by removing the battery, Wang Xifan will discover it.

Looking at the back of the case, Zhou Jiajia felt a headache again, brand machine! A bunch of fragile seals were affixed to the seams of the chassis, with the glaring words "tearing invalid" written on them! It seems. The method of disassembling the chassis to read the hard disk cannot be realized, so we can only find a solution from other aspects.

Zhou Jiajia sighed, exited the study, and came to the living room. Now she could only start somewhere else. Although it took a little effort, she could still achieve her goal. \

It was easy to find the IP address of the router in the LAN, and Zhou Jiajia used a browser to log in to the router's settings interface. Unexpectedly, the page cannot be displayed.

Either the router was too high-end or too low-end. Zhou Jiajia could only log in through the window. It turned out to be a "Yulin" brand router for high-end Internet cafes. Zhou Jiajia has seen several routers of this kind, all priced at more than 10,000 yuan, and they are all for commercial use. Very few people use it. But wealthy families like Wang Xifan may be an exception.

Unexpectedly, the password of the router is not the default password and has been changed. Zhou Jiajia even had a headache. She didn't expect to change the access password of the router at home. What a bad start today!

However, Zhou Jiajia immediately figured it out. It must have been the place where the network engineering staff were set up during the original renovation. There are two advantages to doing this. First, it is to prevent people who do not understand computers from randomly changing the settings. Second, if there is a problem with the network. Just look for them. This will also earn you a network maintenance fee.

I walked around the house twice, very quickly. Zhou Jiajia saw a router at the door where the network entered the home. She couldn't help but feel dumbfounded at first glance. As she expected, in order to prevent others from modifying the settings, this router didn't even have a "reset" button. However, one good thing is that this high-end router has a debugging function. serial port.

As long as there is a serial port, it will be easy! Zhou Jiajia used her laptop to connect to the router's serial port, and then used the Hyper Terminal to easily get the router's password.

After entering the router settings, Zhou Jiajia wrote down the external IP address when entering the home, and then checked the Internet logs in the router.

Currently, only four computers in Wang Xifan’s home have access to the Internet, which is recorded in the router. One is from the laptop I just used to surf the Internet, and the other is the beginning format of the Intel wireless network card, so judging from this, this should be the laptop Wang Xifan uses.

After checking the connection method, it turned out to be wireless access. One of the remaining two should belong to the computer in Wang Xifan's study, and the other to Wang Zhitao's computer.

This makes it much easier to troubleshoot. After seeing the time when the two corresponding IPs access the network, Zhou Jiajia has an idea. The IP of one computer always accesses the network during the day, and the other only occasionally accesses the network at night.

Wang Zhitao has been surfing the Internet at home during the day recently, and the computer he uses to surf the Internet at night must be the computer in Wang Xifan's study.

After understanding this, Zhou Jiajia set the IP of Wang Xifan's computer as "DMZ host" in the router, then restarted the routing. After the configuration took effect, she took off the interface cable on the router and carefully put the router back in place.

In this way, I only need to monitor Wang Xifan's computer every night. After his own settings, the computer in Wang Xifan's study has been completely exposed to the external network from the original LAN.

Although it is not impossible for Zhou Jiajia to intrude without setting it as a DMZ host, it is relatively troublesome. The "Yulin" brand router is a famous hardware firewall router and is not so easy to intrude.

After doing this, Zhou Jiajia wiped the sweat from her face, and suddenly a voice came from behind: "Jiajia, what are you doing?"

Zhou Jiajia's hand was still on the router, and she was suddenly frightened out of her wits. She turned around in fear and saw Wang Zhitao standing not far away, looking at her.

"Uh... That's it. I think the Internet speed is a bit slow. Let's see if there is any problem with the router here..." Zhou Jiajia quickly made up an excuse to cheat with this crappy router. I had long wanted to replace it. Got it! After hearing Zhou Jiajia's words, Wang Zhitao also echoed: "I play games too, it's stuck on me!" "

"What game are you playing? What district are you in?" In order to avoid the embarrassment just now, Zhou Jiajia took up the topic of Wang Zhitao.

"Legend, I play in the Southern Telecom District..." Wang Zhitao said.

"..." Zhou Jiajia was speechless. Wang Zhitao really didn't know any professional knowledge at all. If you use China Netcom's network to play games in the telecommunications area, can you avoid lags?

"Jiajia, in a few days you will accompany me to buy a better router. Don't you understand this?" Wang Zhitao said: "I'm stuck all day long, and I'm going to die..."

"Okay..." Zhou Jiajia said casually, thinking to herself, this router of yours is enough to open an Internet cafe at home, why don't you buy something better?

Wang Zhitao got up and went to the toilet. In fact, he also wanted to check whether the hidden disease in his area was okay. After all, the beauty Zhou Jiajia was right in front of him. It was really uncomfortable for Wang Zhitao to see or eat her.

However, the result was very disappointing to Wang Zhitao, as there was no reaction at all... Therefore, Wang Zhitao still had to pretend to be a gentleman and keep a distance from Zhou Jiajia.

In fact, even if he couldn't do that, Wang Zhitao also wanted to get closer to Zhou Jiajia, but Wang Zhitao was very scared. He was afraid that he would get closer. If Zhou Jiajia couldn't control herself and wanted to be with him, wouldn't he be doomed?
