Chapter 183 Cracking Tutorial

Since today is the weekend, although Vina has to work overtime, she also came back early. By the time Lin Hong and Arthur got home, she had already prepared dinner at home.

After dinner, Vina asked about the Bank robbery in New York. She had seen it on the TV news. If Arthur hadn't called her this morning to report that she was safe, she would have been in a hurry. Of course, she didn't know that her baby son had completely experienced the whole process of the robbery in person. Arthur only said that he was watching at that time.

However, when Arthur later explained the whole process of the robbery to her, he said it in too much detail. If Lin Hong hadn't reminded her in time, he would have almost helped her.

After dinner, Lin Hong and Vina chatted in the living room for a while and then returned to their room.

At this time, the Chinese time should be Sunday morning. Lin Hong thought about it and decided to call his mother. After all, he hasn't contacted his family for a long time.

When he picked up the phone, he remembered the phone knowledge that Kevin taught him today, so he wanted to try to dial with a fork spring.

At that time, it seemed easy for him to see Kevin's shooting. He succeeded after a few snaps, but when it was his turn to practice, he found that it was not a simple thing. The first three code names in China were 086, and 0 represented ten pulses, so he needed to shoot 10 times, but he encountered difficulties here, each interval The time is not accurate, resulting in the failure of dialing every time.

However, after the experiment, Lin Hong gradually mastered the trick, so the interval between each shot was finally fixed at more than 40 milliseconds, but less than 100 milliseconds, and finally dialed his mother's phone.

Feng Wan is still sleeping in at this moment. After a weekend, she can finally have a beauty sleep. Naturally, she doesn't want to let it go. However, receiving her son's phone call swept away all her drowsiness, and she was very happy. Before that, she usually called Lin Hong, and Lin Hong rarely took the initiative to call back. This time, it was a big surprise for her.

The whole call process is the same as before. Feng Wan is asking and Lin Hong is answering. Lin Hong mainly talked about going to Mu Sitong in the past two days. Of course, the robbery in the bank was also concealed in good faith. He had been angry with Mu Sitong for a long time and asked her not to tell her mother about it, so that the family would not worry about it.

After hanging up the phone, Lin Hong took some time to crack the calculator he bought from the store last time. It was much the same, and only a little change in the source code was successfully completed. However, the calculators of other brands have not been cracked yet, but only several other versions of Texas Instruments. After all, the hardware structure and system are different. He has no information about this for the time being and can't do it.

Next, Lin Hong began to write the cracking tutorial and the cracking principle. Although the steps involved are relatively simple, this basic instruction manual is essential. At 12 o'clock, BBS will post the content when it goes online, so that everyone can see and download it in time.

The computer he is using now is much more powerful than the previous APPLE-II, so it is easy to use. Moreover, now he is no longer using "two-finger Zen" for typing, but under Matthew's strong advice, he has specially practiced scientific typing methods. In just one day, he has mastered the fast blind typing method. At the beginning, he was not used to it, but after getting started, he had to admit that this The typing method that has experienced the historical test is indeed scientific, and his typing speed has been greatly improved.

Apart from the design of the key layout, typing training is actually similar to his usual martial arts practice. It is to practice some fixed movements into their own instinctive reactions, or to establish a special reflex belonging to typing in the brain, and there is no need to go through complex thinking. , but it reacts immediately after putting the hand on it, just as simple as we usually talk while doing other things.

Maybe Lin Hong himself has not noticed that the way he thinks about problems has gradually begun to become more mature and rational. When he sees a thing or phenomenon, he often sees the law and essence contained in it through the phenomenon, and involuntarily enters the "God's perspective" as a third party from a Look down at it from a high level.

At twelve o'clock, Arthur knocked on Lin Hong's door.

"STONE, it's almost time. Come to my room!"

"Okay."

This is the exciting moment when they have long agreed to witness the launch of the "SAM Association" BBS together.

When Lin Hong came to Arthur's room, he saw that he was chatting online with Matthew and Pison. He uses an online chat software based on UDP protocol, which can realize multi-party chat on the point-to-point wide area network, but this software is a special software in the Apple system, and there is no such similar software in the DOS system.

Lin Hong is wondering whether to develop one by himself, so that it will be much more convenient for everyone to communicate with each other. Otherwise, because of the different operating systems, it is difficult to communicate with them alone.

The time has reached the last ten seconds, and the countdown numbers that Matthew keeps typing appear in the chat window.

"10"

"9"

......

"2"

""

"START!"

Arthur immediately switched out, started the network dialing, logged in to the network, then opened the TELNET software, entered the domain name of "SAM Association" BBS, and the welcome word after the successful login of "SAM Association" immediately appeared in the interface.

"Welcome to the SAM Technology Frontier Association!"

Under this line, there is a short paragraph of the main introduction to the SAM Association and a description of the calculator cracking of the key works TI-8X series.

These words are all from Matthew's first words, which are relatively general. Of course, they are also a little exaggerated. In his words, he described the future state of the SAM Association, which is not an untrue description.

Below are two simple section names, prompting visitors to choose to enter.

Although both Arthur and Lin Hong are not unfamiliar with such an interface, the feeling of seeing it this time is completely different. After all, this is the BBS that he participated in, and he has a special feeling for it.

So next, the four people of the SAM Association began the process of enriching the whole BBS content.

Before, they agreed not to simply paste and copy the content on other BBS. They must have their own things and be useful to users before they can be retained.

Of course, because their current knowledge is concentrated in the field of calculators, as far as they know, there seems to be no such professional site in the industry. In addition, the cracking of calculators itself started from the SAM group, so they are the founders in this field and have natural appeal, which is not very responsible. The heart is not recognized by others.

Lin Hong returned to his room, uploaded the content of the instruction document he had just written to BBS, and then uploaded several cracking files used to crack the calculator to the public FTP of the association.

At this time, BBS is relatively simple, unlike later generations, which can upload attachments directly on BBS. During this period, file sharing and exchange on the network generally use FTP for file sharing.

The three letters of FTP itself are the abbreviation of "file transfer protocol", which is a protocol based on the TCP/IP protocol and is specially designed for file transfer. FTP has its own server side and client, which is very similar to the WEB server. Users can use special FTP software to connect to the server and download files from it.

Unlike WEB services running on port 80, FTP services generally run on ports 20 and 21. Of course, there are also some unique websites or FTP servers. Considering security factors or other reasons, they deliberately change the default ports of these common services to make others confused at all. If you want to invade, you have to spend a lot of effort to find the port.

Next, Lin Hong continued to publish several posts in the "hardware" and "software" sections, which were some details he learned in the process of cracking the calculator. The most content is a post titled "Teach you how to crack the calculator". In this post, Lin Hong described in detail the whole process of getting the calculator from the beginning, and then starting to crack it step by step, not only the technical details, but also the cracking ideas. What should he think when he encounters obstacles? What do you think?

It can be said that this is a fairly detailed cracking tutorial. Lin Hong's way of writing the article is learned from Wozniak's red book. The content is easy to understand, and sometimes he makes a little joke. Although Lin Hong is not good at it in real life, this does not mean that he also has such a personality on the Internet.

There is a big difference between the online world and the real world. Many people will show completely different personalities in these two worlds, and Lin Hong is no exception.

The network ID he uses is "HELLC".

The reason why he spends time writing such a tutorial is that he wants to be lazy.

Previously, cracking calculators was entirely out of interest, but now, there are so many different brands of calculators to crack. This is no longer an interest, but a labor force. He doesn't want to spend too much time on it at all. After all, the process of cracking is basically the same. He has many other things he wants to do, so he wants to gather the wisdom of the masses, write down the methods and principles, and then call on everyone to crack other types of calculators by themselves, and then share them. In this way, Can you crack these calculators in a short time?

Although not all calculators can be cracked, this process must be explored and tested before it takes time and experience. If Lin Hong has to do it alone, it's really a little terrible. Previously, Lin Hong agreed to build an official BBS, which is in this consideration.

The wisdom of the masses is infinite, and Lin Hong has long had this clear understanding.
