Chapter 542 Action

"It's okay. It should be all right after a few days of rest."

Wang Zhitao said in fear.

"Um, I have nothing to do these days, so come and accompany you..." Zhou Jiajia said.

"Well... That's great. Thank you, Zhou Jiajia."

Wang Zhitao said with a little emotion, "Here you feel like your own home. I can't get up and I'm still very weak, so I can't get up and entertain you..." "It's okay. Just have a good rest."

Zhou Jiajia nodded: "Do you want to eat fruit? Can I get you one?" No... There is hypnotic ingredients in my injection this morning, which makes me a little sleepy..." Wang Zhitao yawned and said, "I'll go to bed first... There is a TV in the living room. You can watch it..." "Okay, then you can rest."

Zhou Jiajia smiled sweetly and said, "I brought my notebook. You don't have to worry about me."

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

Zhou Jiajia crept out of Wang Zhitao's bedroom and then closed the door for him.

After waiting for a while, I heard a slight snoring from Wang Zhitao's room before I was relieved.

Zhou Jiajia came to the living room, first took out a small instrument from her computer bag, adjusted the frequency and began to scan.

Generally, many rich people like to install monitors and so on. Zhou Jiajia is not sure if there is such thing in Wang Xifan's home, so she has to be careful.

Fortunately, the test result is that Wang Xifan did not have any monitoring system installed in his home, which may also be because there is a nanny at home and it is not easy to enter the thief.

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

scanned the computer in the current local area network with software, but no other clients were found.

It seems that it has not been turned on.

So Zhou Jiajia got up and came to the study upstairs. Fortunately, the floor door of the study was not locked. It seemed that Wang Xifan did not guard against himself.

Zhou Jiajia listened carefully to the movement in the corridor, and then quickly came to the desk.

Opened the computer on the desk.

With a crisp sound, the screen stays on the screen of BIOS boot: the BIOS password of the motherboard is actually set! This is the password that gives Zhou Jiajia the most headache. Zhou Jiajia casually typed Wang Zhitao's birthday, no.

I typed Wang Xifan's name again, which was not right. I tried a few more casually, but it was still a mistake.

This password is not like the password of the system.

If it is the operating system password, you can directly use the PE system to boot and bypass the original operating system, but this BIOS password does not work. If it can't be detected, the system will not start at all! Zhou Jiajia had no choice but to dismantle the hard disk! Although the password can be cleared by removing the CMOS battery, it will be found by Wang Xifan.

Looking at the back of the chassis, Zhou Jiajia had another headache, brand machine! A pile of fragile seals were pasted on the seams of the chassis, with the dazzling "tearing is invalid" written on it! It seems.

The method of disassembling the chassis and reading the hard disk cannot be realized, so we can only find a way from other aspects.

Zhou Jiajia sighed, exited the study and came to the living room. Now she can only start again in another place. Although it takes a little effort, she can also achieve her goal.

\\ It is easy to find the IP address of the router in the LAN. Zhou Jiajia logged in to the router's settings interface with the browser.

I didn't think so, but the page could not be displayed.

Either this router is too high-end or too low-end. Zhou Jiajia can only log in with TELNET under the DOS window. It turns out to be a "Fishman" brand high-end Internet cafe router.

Zhou Jiajia has also seen several routers, the price is more than 10,000 yuan, and they are all commercial.

It is rarely used by people.

But rich people like Wang Xifan may be an exception.

Unexpectedly, the password of the router is not the default password, but has been changed.

Zhou Jiajia had a headache. Unexpectedly, there was someone who changed the access password of the router at home.

It's really unfavorable today! However, Zhou Jiajia immediately figured it out, thinking that it was the location of the staff who did network engineering at the beginning of decoration.

There are two advantages to doing this. First, I'm afraid that people who don't know the computer will change the settings randomly, and second, once there is a problem with the network.

I can only find them.

In this way, you can also earn a network maintenance fee.

I circled twice in the room, very quickly.

Zhou Jiajia saw a router at the place where the network entered the door.

At a glance, she couldn't help but be dumbfounded. As expected, in order to prevent others from modifying the settings, there is not even a "reset" reset key on this router, but there is one advantage, that is, this kind of high-end router has a COM serial port for debugging.

As long as there is a serial port, it will be easy to do! Zhou Jiajia connected to the router's serial port with her laptop, and then easily got the password of the router under the super terminal.

Entered the router settings, Zhou Jiajia wrote down the external network IP when the network entered the home, and then checked the Internet log in the router.

It was found that only four computers in Wang Xifan's home had Internet records in the router.

One MAC is the MAC of the notebook he just surfed the Internet, and the other MAC is the MAC opening format of the Intel wireless network card, so judging from this, this should be Wang Xifan's notebook.

I checked the connection method, and it was indeed wirelessly connected.

One of the remaining two MACs should be Wang Xifan's computer in his study, and the other should be Wang Zhitao's computer.

It is much easier to troubleshoot in this way. Looking at the IP access time of the network corresponding to the two MACs, Zhou Jiajia knows it.

The IP of one of the computers 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. The computer that surfs the Internet at night must be the computer in Wang Xifan's study.

After learning about this, Zhou Jiajia set the IP of Wang Xifan's computer to "DMZ host" in the router, and then restarted the router. After the configuration took effect, she took off the COM port on the router and carefully put the router back in place.

In this way, I just 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 extranet by the original local area network.

Although there is no way to invade without setting it to DMZ host Zhou Jiajia, it is relatively troublesome. The "Fishman" router is a well-known hardware firewall router, which is not so easy to invade.

After finishing these, Zhou Jiajia wiped the sweat on her face, and suddenly a voice came from behind her: "Jiajia, what are you doing?" Zhou Jiajia's hand was still on the router. She was suddenly scared out of her body. She turned around in fear and saw Wang Zhitao standing not far away and looking at herself.

"Uh... Well, I think the network speed is a little slow. Let's see if there is anything wrong with the router here..." Zhou Jiajia quickly made up an excuse to cheat with this broken router. I've wanted to replace it for a long time!" After listening to Zhou Jiajia's words, Wang Zhitao also echoed, "I'm playing games too. I'm stuck!" What game do you play? What district?" In order to avoid the embarrassment just now, Zhou Jiajia took on the topic of Wang Zhitao.

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

"..." Zhou Jiajia is speechless. Wang Zhitao really doesn't understand any professional knowledge. If you use Netcom's network to play games in the telecommunications area, can you not get stuck?" Jiajia, you can accompany me to buy a better router in a few days. Don't you understand this!" Wang Zhitao said, "I'm stuck all day long, and I'm going to PK directly with others..." "Okay..." Zhou Jiajia casually said perfunctorily and said, your router is enough to open an Internet cafe at home, and you still want to buy a better one? Wang Zhitao got up and went to the toilet. In fact, he also wanted to check whether the hidden disease in his place was good or not. After all, Zhou Jiajia, a great beauty, was in front of him. It was really uncomfortable enough for Wang Zhitao to see whether he could eat or not.

However, the result disappointed Wang Zhitao and did not react at all... Therefore, Wang Zhitao still has to pretend to be a gentleman and keep a distance from Zhou Jiajia.

In fact, even if he can't do that, Wang Zhitao also wants to be closer to Zhou Jiajia, but Wang Zhitao is very afraid. He is afraid that he will be really closer. If Zhou Jiajia can't control it and wants to be with him, won't he be finished?
