Mining detection of Internet cafe
as there are not only GPUs, but also video memory, power supply unit and a large number of chip resistor capacitor components on the graphics card, long-term mining will lead to aging of some components, so the life of this kind of graphics card is worrying. But as long as the CPU heat dissipation has been good, basically do not worry, the vast majority can continue to serve for a long time.
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 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,
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
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
Mining is burning graphics card, the following methods can identify their own graphics card is mine card
1: through the naked eye to identify whether the hardware is mine card, in fact, through other ways can also be measured, for example, you go to the computer to test the overclocking performance of the mine card, to compare with the official data, to test the stability of the power supply of the mine card, It can also be measured whether it is a mine card or not
2: the first point is to see if there are any dirt and oil stains on the mine card. If not, it proves that the seller may have done better treatment, or it is not the mine card. If the mine card is very dirty, nine times out of ten it is the mine card. Then we have to carry out the next operation, that is to open the mine card
3: we should pay attention to whether there is an invoice with warranty. The warranty can be guaranteed at the warranty points all over the country, which is not a mine card
extended information
how to avoid buying mine cards: try to buy new cards at the official flagship store of Taobao Jingdong, and if you want to buy second-hand graphics cards cheaply, you can't guarantee it
if the budget is really limited and you have to buy second-hand graphics cards, you should also try your best to buy them by yourself. Don't believe that Internet cafes or studios or companies go bankrupt. Most of the cards bought through this channel are mine cards. Of course, if the indivial buyer has a large number of graphics cards in his hand, please be careful. This probability is also mine cards. Finally, I hope you can avoid mine card, buy your favorite graphics card, happy game
now there are special mine cards for mining
if you want to buy game graphics cards, it is recommended to buy new graphics cards in online shopping malls such as Jingdong and tmall
it is recommended to buy them through regular channels. If it is a special second-hand business, there may be mining graphics cards,
We can get obsidian in the process of mining
we need to dig the magmatic layer below - 150 meters underground, and we need diamonds to dig obsidian
What if we don't find Obsidian layer and only see magma
we need three sets of sand and one set of ladders
taking advantage of the fact that the sand can't be suspended in the air, we put sand in the hole we g. At this time, the sand will fall down. When the sand exceeds the magmatic layer, we can stand on it
then we turn on stealth mode, so that our platform is expanded to find obsidian
if we find Obsidian layer when we dig to - 150 layer
we just jump down, and when it's almost there, immediately press the return key to end the game
at this time, if we go in again, it will be in the Obsidian layer
then jump to the next magmatic layer and use a ladder to build the Obsidian layer, OK
Take the SEC's social e-commerce chain, which is a digital asset I often use, as an example. We can check the SEC on the non trumpet of the digital currency market. We can see that the SEC has landed on two exchanges, one is fcoin, and the other is coin egg. However, the prices of the two exchanges are different. Take the figure as an example, if you want to move bricks, you can buy the SEC with a lower price in fcoin first, Then sell it on the higher price coin eggs. After decting the handling charges, you can get a certain difference. The operation of moving bricks is to move bricks. Of course, if you can't move bricks well, you will encounter the change of platform difference. There is still a certain risk ~
our company is similar to you, just print some forms! Simple document, A4 format. I recommend Canon ip1000 printer, I bought it last year, 399 yuan in Changchun Science and technology city. The effect is good, or double ink cartridge (a black and a color) the main thing is to print very fast! It's the first time I've seen such a fast inkjet! ha-ha! Consumables are also cheap, not commonly used color, black original ink cartridge about 40 can be done.
