How to maintain network stability of mining machinery

1.

IPFs is a file transfer protocol similar to http. If IPFs wants to run, it needs many computers (storage devices) in the network as nodes. In a broad sense, all participating computers can be called IPFs mining machines

in order to attract more users to join the IPFs network and contribute to the network, an encryption currency named filecoin is designed, which is distributed to the participants (nodes) as a reward according to the amount of contributed storage space and bandwidth. In a narrow sense, the computer specially designed for the purpose of obtaining the filecoin reward is called IPFs mining machine

because IPFs network needs storage space and network bandwidth, in order to obtain the highest profit ratio, IPFs mining machine usually strengthens the storage space and reces the power consumption of the whole machine. For example, more than 10 high-capacity hard disks are equipped, Gigabit or higher speed network cards are equipped, and ultra-low power architecture processors are used

of course, the mining machine provides storage services, so it can obtain revenue. The size of revenue is related to the configuration of mining machinery and the number of IPFs mining machinery

extended data

the reasons why it is not recommended to invest in IPFs are as follows:

1. IPFs technology is too early to be commercialized

IPFs now takes up a lot of bandwidth. IPNs is very slow at present, which is an obvious technical defect. It will be very difficult to realize dynamic web pages only through IPFs

There is no reasonable economic model, even if the token economy is added, it is difficult to realize the long-term natural ecological value

as a very cumbersome decentralized protocol, it is difficult for users to share files autonomously and spontaneously. In addition, even if users share files into the protocol, the files will be completely open and users cannot delete files effectively, so the security of valid files is threatened

the solution is to introce encryption and blockchain incentive mechanism. At the same time, it solves the security and storage power problems of files. However, as mentioned before, any node with workload proof under blockchain incentive mechanism will face an economic problem of continuous power on state

It is difficult to establish an ecological network with IPFs as the core under the influence of technical problems

The ecological application space of

IPFs is quite limited, and the project interaction speed realized by IPFs protocol is also very slow. Of course, it has a direct relationship with the number of nodes and the distance of calling

2. Close some network ports, which requires high computer technology, as well as programming technology. Generally, we can only turn to operators for help, that is, to improve the network speed.

3. Leading to the current state, because your computer (or auxiliary equipment) is in a sub-health state at the beginning, the emergence of this state is inevitable; It turns out that you didn't have this kind of morbid state, which is a lucky accident; There are many reasons for this phenomenon (of course, user configuration is very important). You need to find your problem thoroughly and comprehensively. Here, the four words "comprehensive and thorough" are particularly emphasized; Any reason is the root of this phenomenon. The problem is the result of your passivity. Take the initiative to rece the problem as soon as possible; I'm like traditional Chinese medicine here: treat both the root cause and the root cause; You might as well according to the following aspects to carefully complete, thorough inspection; In this way, the road of each equipment will be dredged. If the road is dredged, the problem will be solved. Copyright statement: the answer is harmonious original, no one can embezzle! Check the power supply 1.1 use a multimeter to check whether the power supply is stable? 1.2 is the AC voltage fluctuation within the allowable range? Is the ripple coefficient of 1.3a/d power supply (checked by millivoltmeter) qualified? 1.4 is the temperature rise of the power supply abnormal? 1.5 whether the voltage stabilizing characteristics meet the technical specifications? 1.6 whether the voltage stabilizing characteristics and ripple coefficient under rated load meet the technical specifications? 1.7 when replacing a large fan, does your power capacity meet the requirements? 1.8 the power supply of general auxiliary equipment (router, network switch, cat, etc.) is rectifier power supply, which has no voltage stabilizing function. The ripple coefficient is large (which may be caused by dry filter capacitor), and the load capacity is poor; Special attention should be paid. 1.9 e to the over-voltage of the equipment (like feeding a child, too much can last), low voltage (like feeding a child, too little will lead to malnutrition), large voltage fluctuation (like feeding a child, too much to eat, too much to eat), over-current and heating, the overheating protection action will be switched out of fault and the equipment will be out of operation (that is, slow, delayed Repeat start, delay, drop line, interrupt, break line, automatic shutdown, crash, etc; 1.10 whether the over-current protection and over heat protection of power supply operate correctly? Is the movement sensitive? Do you refuse to operate or misoperate? 2: Check the network cable and crystal head (R45): 2.1 whether the crystal head and seat are inserted (loose)? 2.2 is the contact good? What is the contact resistance? 2.3 is there any ash deposit? Is it oxidized? 2.4 is the mechanical locking between crystal head and base locked? 2.5 is the locking firm? 2.6 is the network cable tightly pressed and in good contact with the crystal head? 2.7 the line to line insulation resistance of network lines (using a 100V megger) shall be greater than 20 megohm. Copyright statement: the answer is harmonious original, no one can embezzle! 3: grounding: the main purpose of grounding is to ensure the safety of people and equipment! Multi point grounding, repeated grounding and nearby grounding are the principles; Grounding is divided into protective grounding, shielding grounding and working grounding; Grounding is the most basic requirement for it, especially for analog devices and digital circuits. Interference from all aspects can be eliminated or eliminated through grounding. External interference and coupling between local and local wiring can be eliminated and eliminated. Equipment grounding and shielding work should be done well. Many interference comes from poor shielding and poor grounding, Many people only work on the software, and many interferences are caused by poor grounding or no grounding. This kind of fault is very easy to occur and easily ignored by many people. Many equipment damage is directly related to grounding. No grounding or poor grounding will lead to inter symbol interference, bit error, delay, packet loss, interruption, disconnection (disconnection, interruption), crash, card Automatic shutdown, repeated startup, repeated startup, frequent restart (or repeated connection) and other phenomena. There must be more than two grounding electrodes for grounding, and the interval between each grounding electrode shall be at least 10 meters. The grounding wire from the grounding electrode to the machine room shall not have any joint. Soft copper wire with a cross section of not less than 25 square mm shall be introced into the bus bar of the machine room (no joint is allowed in the middle), and the grounding wire shall be symmetrically connected with the Faraday network to facilitate the diversion of current, The connection point with the bus bar shall be coated with silver powder conctive paste, the cross section of the grounding wire from each equipment to the bus bar (independent) shall not be less than 4 square meters of multi strand soft copper wire, and the grounding resistance of the bus bar to each grounding electrode shall be less than 5 ohm (the smaller the better). At least twice a year, the grounding instrument (more than 2.5 level grounding instrument measurement, and the instrument is within the inspection period) shall be used for inspection. When checking the grounding electrode, it is strictly forbidden to do it in thunderstorm weather. It is strictly forbidden to use the n-zero line of water pipe and power line as grounding; That is, independent grounding device. The line of each equipment shall be connected to the bus bar of the machine room independently. It is strictly forbidden to connect the bus bar in series. I can say subjectively: whether you are an indivial user or a collective user of a large computer room, you are not grounded at all. Copyright statement: the answer is harmonious original, no one can embezzle! 4: Bandwidth: the bandwidth from operators to users is very important. Without enough bandwidth, enough data traffic cannot be guaranteed; It is impossible for computers to get on the Internet smoothly; The bandwidth mentioned above refers to the bandwidth of the whole process. Like on the expressway, there is such a wide bandwidth that there can be no fluctuation in the whole process; A little fluctuation in the whole process will affect the network speed; The user has the right to ask the operator (test with sweeper) for protection; 5: Signal to noise ratio (signal to noise ratio, which can be understood as signal purity) is small, the useful signal is covered by the noisy spurious signal (especially the inter symbol interference), so that the way to receive the signal can not correctly extract the useful signal from the noisy signal, and the judgment circuit can not correctly judge the code element, which will lead to error code Serious bit error is packet loss, serious packet loss is the cause of delay, and serious delay is line dropping (slow, delay, repeated start, line dropping, delay, line dropping, interruption, line breaking, automatic shutdown, crash, etc.). Use a noise meter or level meter to measure whether the noise level is within the allowable range, Or use oscilloscope to observe whether there is stray signal? Is there inter symbol interference? Take measures to eliminate it. The signal to clutter ratio should be more than 60dB. Test (observe) with sweep frequency instrument and oscilloscope. This indicator is to ensure that the road is smooth and barrier free. There is such a wide road, but also the whole process barrier free. 6: Matching: matching includes level matching and impedance matching (test with level meter and signal generator). 6.1 level matching: the received signal should not be too low. When it is too low, it can not reach the threshold level required by the receiving Road, and the equipment can not work normally; If the level is too high, the front-end circuit will be saturated or burned out. If the receiving level fluctuates near the receiving threshold, the computer will restart frequently; Therefore, receiving level adjustment is very important. Use level meter or oscilloscope frequently in operation to monitor and adjust the receiving level at the connection within the appropriate range. According to the instruction, monitor the adjustment with a level meter. 6.2: impedance matching: the connection point must match the impedance relatively. If the input and output impedance do not match, it will lead to reflection attenuation, and no matter how strong the signal is, it will not work normally. 7: Optimize the network structure, people turn on the computer to access the Internet will proce garbage, just like eating, not cleaning the table, not washing the dishes, not cleaning the stove will proce computer garbage, the computer will graally show slow, card, delay, repeated start, offline and other failures; Therefore, I recommend using some small tools: such as super rabbit, optimization master, Lu master or 360, etc; Develop a good habit of cleaning up rubbish before going offline. 7.1: timely removal of garbage fragments and ie cache generated by the Internet: as long as you use the computer, garbage will be generated. If you don't clean it in time, it will accumulate more and more. If you don't clean it for a long time, it will make the running space of C disk smaller and smaller and disorderly. Finally, it will slow down graally until it crashes; Therefore, regular sorting and running C disk can keep the computer running speed. 7.2: synchronize the ADSL device first: power off the device and restart it. 8: Software settings and configuration 8.1: common software download software to the official website as far as possible, do not install 3, informal software does not install, P2P (occupy resources) software does not install, not commonly used software does not install. Turn off all unnecessary network connections and startup items, such as Thunderbolt, BT, donkey, etc; Do not put the non running software in the running C disk; Update patches in real time. Game software should be downloaded from regular large websites. Pay attention to whether the software is stable. Immature and unstable software will lead to slow, card, crash and other failures, especially some popular game software. Some netizens have a strong response to this. Such software should be paid special attention to or deleted immediately; When downloading software, we should pay attention to the rogue software inserted into the critical computer security, at any time to clear. Some game software started, the game will be directly t off, after the unlimited drop, restart and other failures. Protocol: the protocol in the network should also match it, and mismatching will also cause some equipment failures. Software conflicts will also cause delay, card, slow, crash, offline, interruption and other issues. 8.2: antivirus software and firewall at least one valid genuine antivirus software, and often upgrade the virus library: proper firewall settings (not too much, too high, too low), will cause some web pages can not be opened; Virus can make the computer slow down, crash, drop line, card, repeat start and switch failure. 9: Temperature, humidity and temperature rise (the temperature is graally rising after power on) with the extension of power on time, the temperature of the main equipment and its auxiliary equipment (cat, router, network switch, etc.) will graally rise. If it can not be sent out quickly, it will change from delay - slow - line drop - crash. 9.1: humidity: in rainy season or rainy days and areas with high humidity, the insulation between lines and devices is reced, and the signal level drops, resulting in inter symbol interference, bit error, delay, packet loss, interruption, disconnection (short line or interruption), crash, automatic shutdown, repeated startup (repeated connection), or unstable operation of the computer. Humidity accelerated oxidation, resulting in transmission interruption. 9.2: temperature (recently, with the graal increase of temperature, the faults caused by temperature will graally increase): from the start of the machine, the temperature will graally increase. When the temperature rises to a certain value, it will be stable at this value, and the difference between this value and the ambient temperature should not be greater than 25 degrees; As the computer is a semiconctor device, the actual temperature of the device should not be higher than 85 ℃; When the chip temperature is close to 80 degrees, measures should be taken to rece the working environment temperature of cat, router, network switch and computer equipment. If beyond this range, the computer will proce inter symbol interference, error code, delay, packet loss, intermittent, offline (disconnection or interruption), crash, automatic shutdown, repeated startup (frequent connection) and other phenomena. 9.3: the temperature rise (the difference between the actual temperature of the equipment and the ambient temperature is called the temperature rise) is less than 25 ℃. The temperature has a great impact on the normal operation of the equipment, especially when the network switch, router, computer motherboard chip and network card have a large isothermal rise, the equipment will not work; especially

4. I don't know about you
1 Hardware stability, including lines, ports, power supply, optical conversion (more problems)
2 software stability, firewall, router kernel version update, intranet virus firewall, anti ARP, anti DDoS, etc.
3 there are no examples of stability, only instability:)

5. 1、 Rece frequency band interference:
when we publish wireless networks, we will choose a frequency band. Theoretically, too many wireless networks in the same frequency band will seriously affect the signal strength. That is to say, if the wireless signal frequency band adopted by your home is the same as that of other home, then to a certain extent, the two wireless networks will be affected. So when the network is unstable, it is a good way to change a signal transmission band through the wireless router< Second, reject DHCP packets:
experienced users all know that DHCP service can help us to automatically assign IP addresses to computers in the network, but in practice, DHCP will cause network instability. For example, when the lease arrives, we can get IP again and find that other computers in the network are already using this IP address, Or the DHCP information is frequently negotiated between the computer and the wireless router
in fact, these DHCP packets are completely unnecessary. For ordinary home users, there are not many computers in the network. We can rece DHCP packets by manually setting IP address and other network parameters
a friend once told me that the wireless network in his home was very unstable. Later, he didn't use DHCP to specify IP directly and never dropped the line
Third, speed down to improve stability:
first, let's take a look at this example - two people form a wireless network, his wireless router is D-Link, and my side is Netcom wireless bridge. Recently, there are frequent disconnection, and the connection speed is very slow. After checking, we found that we didn't know when another Linksys device (Linksys signal is very strong) occupied Channel6. As soon as it started up, it would affect our connection quality. The original packet loss rate of Ping soared from 1% to 50%. After that, the frequency band of the transmitted signal was adjusted to channel 1. Who knew that two devices of channel 1 were found nearby, and then there were five wireless devices in channel 11
the above example is met by the author himself. It can be seen that wireless networks are very popular now. As the same band wireless networks will interfere with each other, the 13 frequency bands are not enough for everyone. How can we solve this problem? Generally, wireless routers have the function of automatically selecting the frequency band. If not, you can change the working mode of your wireless device from 802.11g to 802.11b. Although the speed is reced, but it brings the benefits of stability, so to a certain extent, recing the transmission speed can make our wireless network more stable.

6. If the day is normal and the Internet is slow at night, it means that there is a problem with website resources or network lines. There is no way, because the evening is the peak time of Internet. If this is not the case,
it is recommended that you 1, check whether the system is normal, clean up the computer, 2, test the online speed to see the results,
3, if it is not normal, please call customer service to declare the fault, and the technical staff will deal with it. Thank you ~ ~
4, it may be the network cable aging, you can replace it
5, and check if there is a problem with the router. It is recommended to restart the router or rewrite the router IP. For example, it used to be 192.168.1.1. It can be changed to 192.168.0.1. General router default user and password are admin, you can try
6 or maybe there is something wrong with your line, you can call the customer service of Netcom to ask why the network speed is slow, and the customer service will ask you to test your current network speed first. If there is a special speed measurement website, the customer service will say, the test is OK, that is no problem
7, if it is a computer machine problem, it involves the network card, cat, network cable, network cable interface, computer network cable interface, And other related hardware problems
8, poisoning will also slow down the network speed, you can right-click your dial-up connection, that is, the flash of the small computer in the lower right corner, to see whether your receiving and sending are basically the same, if the amount you receive is far less than the sending, then it is estimated that you are either poisoned or in the Trojan horse, speed kill the Trojan horse

7. 1. The broadband provided by network operators must be stable
2. The linked wireless route must be stable
3. The Internet equipment must be stable (mobile phone, notebook & lt; Wireless network card & gt;)
4. The distance between Internet devices and wireless routes should not be too far.

9. 1、 Wiring problems
first check the wiring at home to see if the connector in the house is connected properly and if the wiring passes through any interference source, such as air conditioner, refrigerator, TV, etc., and try to keep a certain distance from these electrical equipment. In addition, the power line should not be paralleled with the ADSL line, in order to avoid crosstalk, resulting in ADSL failure. In addition, there are many other factors that cause network instability, such as signal interference, software conflict. The mobile phone, which has a large radiation, must not be placed next to the ADSL modem, because the mobile phone will automatically find the network every few minutes. At this time, the strong electromagnetic interference is enough to cause the ADSL modem to cut off the current
Second, the network card problem
the network card is usually PCI network card or on-board network card. When you choose, you must choose the one with better quality, otherwise the quality of Internet access may be poor. 10m or 10m / 100M adaptive network card can be used. In addition, many machines share the Internet and use al network cards, which also causes conflicts, which is also worthy of attention. At this time, you should pull up the network card connecting to the LAN or other computers, and only use the network card connecting to ADSL to test the Internet. If the fault returns to normal, check whether there is any conflict between the two network cards
Third, ADSL modem or network card setting problem
now modem generally has two working modes, one is the normal mode of using dialing software, the other is the routing mode of automatic dialing. In normal mode, you don't need to set modem, just use the default mode. The routing mode needs to be set. Modem has its own flash memory, which can save the account and password box settings for automatic dialing. The most common method is to set the IP address of ADSL modem or DNS server incorrectly. Because for ADSL virtual dial-up users, there is no need to set the IP address, which can be automatically assigned. TCP / IP gateway generally does not need to be set. But set DNS must be set correctly, DNS address can be obtained from the local telecommunications department. In addition, TCP / IP settings are most likely to cause the situation of not being able to browse web pages. Generally, it is set to automatically obtain the IP address, but DNS must be filled in. Other default can be used
Fourth, ADSL modem synchronization abnormal problem
check whether your phone line and the ADSL connection are in poor contact, or there is a problem with the phone line, the poor quality of the phone is particularly prone to drop, but this problem is not easy to check, so be sure to use a good quality phone line. If it is suspected that the separator is broken or the ADSL modem is broken, try to directly connect the external line to the ADSL modem without using the separator. The connection between the separator and ADSL modem should not be too long, otherwise it cannot be synchronized. To eliminate the above situation, as long as the ADSL modem is restarted, the synchronization problem can be solved
fifth, operating system, virus problems
in addition to the above-mentioned line conditions, there are also computer system problems. For example, the legendary killer caused the LAN to drop. This problem occurs in a large area all over the country. The virus will affect the Internet cafes (LAN) of host agent and router agent. Legend killer is a destructive software that can cheat LAN by ARP and create virtual gateway address to collect login information of Legend game in LAN and analyze it to get user information. Workflow: first of all, broadcast local Mac to LAN by ARP Cheating, so that the workstation in LAN mistakenly thinks this machine is gateway. This process will cause the connection between LAN and Internet to be interrupted, When the user restarts the game and logs in the account, the account information will not be uploaded to the proxy server directly through the gateway, but will be uploaded to the legendary killer software which is carrying out ARP deception, Attack situation: LAN and Internet link speed suddenly slows down or even breaks down. Online games break off the link, and after logging in again, the server will be prompted that there is no corresponding response. It is suggested to check and kill the virus first; If you have the ability, re install the system; If the machine has two network cards, unload one network card; It is suggested that users who are not familiar with computers should not install all kinds of firewall software at will. Incorrect settings will cause unstable Internet access. Some operating systems may have compatibility problems with ADSL related components, so you can go to Microsoft to upgrade the system or repair the system. If possible, it can be reassembled. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods< (6) the firewall and IE browser are not set properly.
although ADSL is less likely to be attacked by hackers and viruses, it does not rule out the possibility, especially web viruses and worms. If the virus destroys ADSL related components, there will also be a disconnection phenomenon. If it can be determined that it has been damaged and attacked by the virus, and there is a disconnection phenomenon, it is necessary to check the installed firewall, proxy server software for sharing the Internet, Internet acceleration software, etc. after stopping running such software, it is necessary to test the Internet to see if the speed returns to normal. If the Internet is not stable, you can try to turn off the firewall first, test whether it is stable or not, and then set it accordingly. In addition, firewall or IE browser failure can also lead to normal connection, but can not open the web page< Seven, static problem
static is an important factor affecting ADSL, and the power supply in the home is generally not grounded, coupled with the interference of various electrical appliances (such as refrigerators, TVS), it is easy to cause static interference, resulting in frequent disconnection of ADSL in use, please lead the grounding terminal of the three core socket out of the wire and make a good grounding, which can generally solve the problem of disconnection. General solution: add grounding wire to solve the problem of disconnection< Eight, software conflict problem
there are two ways for ADSL to access the Internet: virtual dial-up and private line access. Now most of the ADSL of indivial users are virtual dial-up. PPPoE (point-to-point protocol over Ethernet) virtual dialing software has its own advantages and disadvantages. After many tests on different operating systems, if the operating system is Windows XP, it is recommended to use its own PPPoE dialing software, which has less current interruption and relatively improved stability. If you are using Windows me or 9x, you can use the following virtual dialing software -- enternet, winpoe, raspppoe. Among them, enternet is now more commonly used, and enternet 300 is suitable for Windows 9x; Enternet 500 is suitable for Windows 2000 / XP. When you have problems with one PPPoE dialing software, you may as well uninstall the software and use another PPPoE dialing software. Please be careful not to install multiple PPPoE software at the same time to avoid conflicts. Because the telephone line is the main way of broadband access, so we must set up a virtual channel. If several kinds of dial-up software are mixed, it will cause conflicts, resulting in network instability. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods. For example, some friends BT download will lead to network offline. It may take too many threads to download, resulting in disconnection
in addition, besides the above reasons for your own computer, the reasons for QQ and game offline may also be related to their own server restrictions and server attacks or failures.
