How to check the mining program
mining chip has gone from CPU mining to GPU mining to FPGA mining, and now it has entered the era of ASIC mining. However, the way of mining has also experienced from one or two mining machines to small mining machine workshops, and now it has entered the era of large-scale mining
(1) mining mode: from one miner to large-scale mine
if you start to try mining, you need to prepare a miner, a computer with internet connection, an AUC, a raspberry pie, power supply and various connecting cables. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply
common computer mining methods:
1. Download and install gpu360 miner
2. The software will be set to boot, it is recommended to boot. Because it has a very human function, when you don't use the computer, it will automatically mine, when you use it, it will stop instantly, it will not affect the normal work and use
3. After the software is started, change it to your own mobile phone number. After the software starts, there are three setting options:
4. The first time you start mining, you will test the equipment, and it will test your best mining scheme. It usually takes about ten minutes
5. After testing, it will automatically enter the mining state
6. Click stop and close to minimize to the tray, so that when you don't use the computer, it will automatically open to make money
right click the icon to shut down the software completely
7. bitcoin earned can be exchanged directly in online stores.
In fact, it's not difficult. When we use mobile phones everyday, there will be some background applications, which will be "killed" after restart. However, if the mobile phone is hacked and rebooted, it will enter a high load state again, and the system running memory will be used up quickly. Therefore, if the mobile phone is stuck, hot or dead for no reason, it may be g
it is possible that hackers steal all the information before using mobile phones to "mine" cryptocurrency. People will not only encounter problems such as cell phone stuck, fever and even crash, but also other financial losses
moreover, it is worth noting that some mobile mining apps, in the name of "mining", allow users to invest money and continue to develop offline
a new customer recently consulted with sine security company, saying that his server often fails to open the website of the card, and the remote connection to the server is extremely slow. Sometimes the Ping value reaches 300-500, and he often switches. After listening to the customer's words,
will generally judge that he has been attacked by CC + DDoS mixed traffic, It's strange to say that there is no traffic attack on the computer room. It's not a traffic attack, but it also causes the server card and website to fail to open. What kind of attack is this? In order to solve the problem of
client server card, we immediately arranged a security engineer to carry out security detection and deployment on his Linux server
{rrrrrrr}
Mining Trojan horse is also designed. If the mining process is forced to stop by customers, it will automatically start to continue mining to achieve uninterrupted mining.
careful inspection shows that it is through setting the hourly task plan, remotely downloading shell mining Trojan horse, and then executing, Check whether the current process exists or not. If not, start the Trojan horse to mine
a detailed security inspection was carried out on the client's Linux server. It was found that fortunately, there was no encrypted server data, and the worm was infected with the disease
virus. If the data was encrypted, the loss would be great. The client was a platform, and the client's data was very important. After finding out the mining Trojan horse,
do customers need to know how the server is attacked? Was the Trojan horse uploaded? It can prevent the attack
in the later stage
through the security detection and analysis of our security engineers, we found that the server uses Apache Tomcat environment, the open architecture of the platform is JSP + Oracle database, and Apache Tomcat uses the version of 2016, which leads to the serious remote command execution vulnerability of Apache, Through this vulnerability, the intruder can directly invade the server and get the administrator permission of the server,
sine security engineer immediately repairs the Apache vulnerability and clears the Trojan horse. So far, the problem has been solved, the client server
runs stably, and the network station opens normally strong>
robots or excavators equipped with computers and related programs can use different tools according to different geological environments.
such intelligent equipment system can mine.
log in to the server and use top to check CPU usage. This program called minerd consumes a large amount of CPU, as shown in the figure below:
this program is not our normal service program. I think it must be hacked, Then I searched this program. It's really a mining Trojan horse program. Now that I know it's a Trojan horse program, let's see how it works, and then how to repair the back door
this program is placed under / opt / minerd. When it is determined that it is not related to the project, it is judged to be a Trojan horse program, decisively kills the process, and then deletes the minerd file under / opt

In the last month of 2017, bitcoin's nearly crazy rise has made many investors make a lot of money. Many novices who are waiting on the sidelines can only sigh. For many novices who want to enter the instry, the biggest problem is how do I judge whether a virtual coin has investment value
generally, the simpler answer is: if you want to be stable, you should invest in mainstream currencies, such as BTC, ETH, dash, LTC, XRP, and so on. If you want to be small and broad, you should invest in some counterfeit coins or pheasant coins. So the question is again? How to choose so many pheasant coins
the first method is to identify the project itself, including its background, white paper, team, operation, code and ICO release plan
first of all, the most basic question is whether the project is a legal and compliant project. If the project itself is exploiting the loopholes of the law, the project will be forced to stop sooner or later
secondly, the white paper and the team are very important components. The white paper needs to pay attention to the contents and channels of publication. If the white paper can not see the prospects and core competitiveness of the project, it will not have any value. The same is true for the team. If the team members are people without background, it is likely to be a project with money
finally, the operation of the project is related to the release plan of ICO. The operation of the project determines the development route of the project and the integrity of its internal structure, while the release plan of ICO can judge whether the ICO is successful or not
as for the code of the project, it's not necessary for novice Xiao Bai to analyze it, but he also needs to understand it
the second method is a more professional analysis method, mainly through the strategic positioning of the project, market awareness, liquidity, risk and technology
Strategic positioning is to analyze what problems this project is mainly used to solve. For example, bitcoin aims to change global payment, while Ethereum uses blockchain to make various smart contractsmarket awareness refers to the brand promotion of the project itself and the attention of users and media, including the information sources of social platforms such as twitter and Facebook
liquidity, the so-called liquidity is to see how much attention each platform attaches to the token of this project. Secondly, the weight of the platform itself is also very important, so you can choose the currency on some larger platforms
risk and technology. Risk naturally refers to the risk of issuance mechanism and inflation. For example, the hard bifurcation of Ethereum is a kind of risk. In terms of technology, it mainly depends on whether there are bugs. At present, bitcoin technology is the most complete. Although it can not support computer language, it is still relatively perfect in cryptography and so on, with few bugs
the third is the commonly used principle of blockchain investment, namely:
1. Does the world really need this
2. What problems did it solve that were not solved originally
Is decentralization really necessary Does it really have to make its accounts public Does accounting disclosure really improve its efficiency To what extent is it closer to a DAC (decentralized autonomous Corporation) If we decide to invest, what proportion of our capital should we investthe fourth and most direct choice is to choose the currency according to the exchange
for example, when we want to see a movie, we always choose the movie that is shown in a bigger cinema, because we always think that the movie that can be shown in a bigger cinema should not be too bad. It's the same with currency selection. The currency that can be listed on a big exchange will not be too bad, because a big exchange will consider its own influence while reviewing the currency. No authoritative exchange will go to a junk currency to ruin its reputation
the above four currency selection techniques are for your reference only. Finally, I would like to remind investors that virtual currency itself is a high-risk investment project, and sudden rise and fall is a common thing. I suggest you choose currency carefully, and at the same time, remember not to invest with the heart of sudden wealth, Timely stops are also important
