Shenhao Black Technology Network Developer

"Ding Ding Ding", Lei Luo's phone rang suddenly, and when he picked it up, it turned out to be Fan Xiaobing. Since the last time I left Yunzhou, I haven't contacted him for a long time!

However, Lei Luo is not in the mood to recall the ecstasy scene between Kundu Hotel and Fan Xiaobing. It is the time for a mess in his head!

"Lei Dong, where is it?" Fan Xiaobing's lazy voice came.

"Bingbing, what about the United States, what's the matter?" Lei Luo is now in a state of tension, and his voice is inevitably a bit blunt.

"I am now shooting in the magic city. I thought of your home court. Why would you want to kill you? You hid in the United States? What? The capitalist life is very fascinating, right?" Fan Xiaobing automatically ignored Lei Luo. His tone became soft and blunt.

"Capitalist life?" Lei Luo was stunned, only then did he remember where he had enjoyed the capitalist life? I'm as busy as a dog these days, the red light district? Casino? These seem to be far away from him.

"Okay. Seeing that you are not fainted, you should not be embarrassed. Please remember to invite me to dinner when you return to the Demon Capital." Fan Xiaobing is a human being. He obviously feels that Lei Luo is doing something right now, so there are not too many. Said and hung up.

After hanging up the phone, Lei Luo's mood calmed down a lot. Only then did he remember that this DEB mission could be completed so easily, and Li Jiaxin's help was indispensable. If she hadn't come to match the bridge, how could she complete this mission so quickly.

Lei Luo quickly called Li Jiaxin to express his gratitude! Although the system mutated after the task was completed, it was not Li Jiaxin's fault!

After the two phone calls, it was early in the morning, but Lei Luo's brain became more sober and calmed down, not as highly nervous as before.

Lei Luo lay flat on the bed, immersed in the system again.

Entering the [Terminal] panel, Lei Luo first inquired about the programs running on the Linux system.

When a program is running on Linux, there are two common ways, one is to start the program directly from the command line; the other is to start the program as a service.

However, in either way, a process will be started in the system. So Lei Luo typed the system command first and looked up the system process, and found a suspicious process, because this process was started by java command, obviously a self-developed application.

[Java-jaroptshhkjshhkj-0.0.1-SNAPSHOT.jar]

The last string optshhkjshhkj-0.0.1-SNAPSHOT.jar of the above command is the path of the jar file after the software is finally compiled. Through this path, Lei Luo can find the corresponding program.

This file is a compressed file compiled according to the software source code. Lei Luo first decompresses it to get all the compiled class files, and then decompiles these class files.

Lei Luo glanced around, the whole program uses swing architecture, which is a desktop application software based on Java language. After the program is started, a main panel will be displayed, which is the property panel of the system. In the whole panel, there are several sub-panels such as [Mall], [Task], [Auxiliary], [Warehouse] and [Terminal].

Lei Luo continued to check the source code and found that all data requests were directed to a server shhkjserver. This is a host name, not a network address, and has no meaning.

Lei Luo continues to use the ping command. On the one hand, he will check whether the corresponding host is active, on the other hand, he will return the network address corresponding to the host.

Lei Luo quickly executed the order:

[Pingshhkjserver]

Then, you can see the network address corresponding to the entire host:

【2001:0DB8:0000:0023:0008:0800:200C:417A@w1312】

The address before the "@" symbol is an ipv6 address, the standard was published in 1996, and our commonly used network addresses are in ipv4 format, for example:

【192.168.0.1】

This address is familiar to everyone, but the range of the entire address is limited, so with the ipv6 address, it has a larger range and can express more network addresses.

But what the hell is this [@w1213] behind? Generally speaking, @ means at or in. This address is slightly translated:

A network address on W1213 2001:0DB8:0000:0023:0008:0800:200C:417A

So, the question now is, what does w1213 mean?

Lei Luo thought for a long time and didn't figure it out. Since he didn't understand, he had to skip it temporarily.

Knowing the server address of [Network Shenhao Hacking Technology System], Lei Luo is ready to hack in and take a look, but to hack in, you need to crack the root user password of the server first.

The root user of the Linux system is equivalent to the administrator user in the windows system, and is the user with the highest authority.

Cracking the password requires a variety of small tools and software, which Lei Luo had previously placed on the server in the spatial warehouse. Now the space warehouse has placed many servers, including QQ server, file server, portal server, mall server, security server, etc. The hacker's tool software Lei Luo has been placed on the security server.

The address of the security server is 39.112.108.182, which is an ipv4 address. Lei Luo probed it in the system's [terminal] command line and found that it was not active at all.

Generally speaking, there are two reasons for inactivity: one is that the host corresponding to this address does not exist or is not allowed to be probed; the other is that the host corresponding to this network address is not connected to the current terminal's network.

But Lei Luo still thinks about a possibility, that is, the parameter of this address is not enough, because in the address of the system server, there is a "@w1213" in the end, although Lei Luo doesn't know the meaning of this parameter.

Lei Luo thought for a while, and typed a command to query the address of the current terminal, and found that the address format is exactly the same as the format of the system server:

[A3D1:FDB8:0090:DB23:7378:0812:297C:81CA@w2354558]

The following parameter becomes: w2354558

Lei Luo once again probed the address of the security server in the command line of the system [terminal], but this time added @w2354558 after the ipv4 address

【Ping39.112.108.182@w2354558】

The result of this investigation was actually active, Lei Luo couldn't help being overjoyed, and he seemed to realize it suddenly. This w2354558 represents the real world Lei Luo is currently in. To access the network address in this world, you must add @w2354558 to identify it.

So, w1213 represents another world? The number starting with w is the number of the world? Lei Luo roughly sorted out the clues. w is the first character of world, it is a rice word, and the Chinese word means "world"! ! !

"This world might be another interface, right?" Lei Luo doesn't feel strange to come to such a conclusion. He is reborn and has a system. Isn't it allowed to have multiple interfaces? You can’t just allow officials to set fires and forbid the people to light the lights, right?

Although Lei Luo doesn't know how the network of another world connects to his own world, it doesn't prevent him from understanding this thing in this way!
