Professor Xia led Xiao Yuan out of the room where they had assembled, found an employee of the foreign trade company, and told them their requirements, and the employee took them to another office of the foreign trade company, where a computer was placed, and after sending them here, the employee left.

"Little comrade, this computer can access the Internet, let's start." Professor Xia said, with a little anxiety and some expectation in his words.

"Okay." Xiao Yuan nodded to Professor Xia, sat down next to the computer, and pressed the computer's power button.

When Professor Xia started the computer, he also moved a chair and sat next to the computer, waiting for the computer to start up with Xiao Yuan, and did not open his mouth to disturb Xiao Yuan.

The computer soon entered the desktop, the system of this computer is the English version of windows98, of course, the English version and the Chinese version of the system are only different in language, the function is exactly the same, for Xiao Yuan, can not cause any trouble.

"Little brother, you have no problem with the English version of the system, right?" Professor Xia was a little worried, so he asked.

"No problem, English and Chinese are just a shell, and the real things are all the same." Xiao Yuan said, his eyes did not leave the computer screen, nor did he touch the mouse on the computer desk, his hands crackled on the keyboard, he wanted to familiarize himself with the environment of this computer first, and understand what software could be used in it.

Professor Xia saw Xiao Yuan operating the computer so skillfully, a trace of surprise flashed in his eyes, but he no longer bothered Xiao Yuan.

Obviously, Xiao Yuanquan's way of operating the computer with shortcut keys gave Professor Xia a great shock, among the computer masters he has seen, there is no one who can completely use the mouse, all use shortcut keys to use Windows, you know, windos is fundamentally designed for mouse operation, although the use of shortcut key operation, can greatly improve the efficiency of use, but this high efficiency is based on the extremely proficient mastery of the Windows system and its shortcut keys, if not, Using shortcut keys will only reduce efficiency, not improve, so he saw Xiao Yuan operating the computer in front of him so skillfully, although he hadn't started his official work yet, his confidence couldn't help but increase a little, and his original worries were also weakened a lot.

Xiao Yuan didn't have the heart to pay attention to Professor Xia's shock and mental activity, in fact, when he sat next to the computer, since the computer was turned on, he had become distracted, this was his consistent trait, if it weren't for this, he probably wouldn't have reached the height of his previous life.

"Professor Xia, what is the IP address of the AIX server over there in Hemengzhai?" Xiao Yuan searched the software installed on the computer, sat down in his heart, and asked before starting to work.

"I don't know." Professor Xia replied, and after speaking, he said with some concern, "I don't know their IP address, how can you hack in?" ”

"It's a bit of a hassle, but that's okay." Xiao Yuan said, while speaking, he opened the web browser on the computer, quickly entered an address in the address bar, entered the domestic cold fire forum, and downloaded several network tools from it, although he can also write these tools, and the tools he writes are more convenient to use, but he did not plan to write it himself, first, because the time is urgent, and more importantly, because he does not want to expose too much in front of Professor Xia, so he chose to download it from the Internet.

Xiao Yuan's computer was connected to two megabytes of broadband, and those tools were not large, so it only took a few minutes to download them all to the computer.

Xiao Yuan opened a tool and a list of IPs downloaded from the Cold Fire forum, imported them into the tool, and then ran them, and when the results of the tool came out, Xiao Yuan opened another scripting tool and began to write a piece of script code in it.

"What did you use that tool for, I see you use a lot of foreign addresses?" Professor Xia asked.

"Set up the springboard." Xiao Yuan replied, but he didn't intend to explain anything, the gadget just now was a simple springboard setting tool, and that list was some IP addresses that some hackers announced on the cold fire forum that could be used to make broilers, here, he didn't plan to set up too complicated springboard rules, but used the tools written by others to set up a simple linear springboard, the reason is still because of the urgency of time, and the reluctance to expose too much of his own things.

"Is setting up a springboard a basic means of hacking?" Professor Xia asked again.

"Yes." Xiao Yuan said, and asked casually, "Professor Xia, what does a hacker look like in your mind?" ”

"Traditional hackers should be some people who have a fanatical interest in computers and have extremely high technology, but now it seems that people have narrowed the meaning of hackers, referring to hackers, especially those who spread viruses everywhere, computer masters who invade and destroy computer systems, that is, those black hats in traditional hackers, and white hats in hackers People prefer to call them computer security experts."

Xiao Yuan was a little surprised by Professor Xia's words, it was the first time he heard someone take the initiative to say the original meaning of hackers, so he couldn't help but glance back at Professor Xia and showed him a rare smile.

"You still know Perl?" Professor Xia also thought Xiao Yuan smiled, pointed to a large piece of code he had written on the computer screen, and asked.

"Understand, this code is for that AIX server." Xiao Yuan said that Professor Xia's insights about hackers just now had successfully won his favor, so he spoke a little more, and his tone was no longer as cold as just now.

As he spoke, his hand didn't stop, the sound of crackling keyboard tapping became a chorus, and the perl code grew longer and longer, soon exceeding a page.

Professor Xia saw that Xiao Yuan's attention was all focused on coding, and he also closed his mouth in amusement, not bothering him again, only occasionally glancing at Xiao Yuan with a strange gaze.

It took about twenty minutes, Xiao Yuan finally wrote the perl code, ran it in the simulation environment where he downloaded the tool, checked that it was correct, saved the code, and opened the tool that automatically set the springboard to see, the tool had already finished running, and the results showed that a linear springboard with thirty-six computers was successfully set.

Although the protection of this linear springboard is much worse than his ring logic lock, but for the time being, it can only be like this, fortunately, the setting springboard tool he downloaded also provides a real-time monitoring applet, that is, once someone tracks him through the springboard, this monitoring program will be the first to find and alarm.

Xiao Yuan turned off the springboard setting tool and turned it off, leaving only the monitoring applet running in the background, and then opened another tool, and after setting it up, it was run.

"What is this for?" Professor Xia asked after seeing that Xiao Yuan had run this program, and he was idle for a while.

"To scan the telecom gateway in Dongji City, we need to control this gateway first to prevent the other party from transmitting the data, and you don't know the address of the AIX server, I can only enter the server of the Dongji City Telecom Department first, get the IP allocation table in this area, scan all the IP addresses, and find the address of the AIX from it." Xiao Yuan explained.

"Won't that take too much time?" Professor Xia asked with a frown.

"It's definitely more time-consuming than knowing the IP address directly, but there's no way around it, so it's the only way to do it." Xiao Yuan said.

"Alright then, try to hurry, and if there is no result at five o'clock, notify the mountain wolves and let them act." Professor Xia looked at his watch, it was almost four o'clock, and there was less and less time left for them.

Xiao Yuan did not immediately respond to Professor Xia's words, because the scanning tool only needs to scan one IP address, so the scan results have already come out.

After looking at the scan results, Xiao Yuan turned around and said to Professor Xia, "I shouldn't have to take risks with my comrades-in-arms." ”
