Tags: serve using more than open installation method to run the LAN via spanThe person who can see this blog note that the attempt failed, will find that the memory card after the flash into Ubuntu, unable to operate the Raspberry Pi via ssh. It is because the official Ubuntu system needs to set something for the first time, similar to the initial startup of Windows, if not set up, even the operation account is not (root), so even SSH can not use the eggs. So you need to choose a non-official, s

Air Blowing Principle Gas Blowing cables/tubes are used to push micro-tube bundles or micro-cables to the pipe, while the air compressor sends powerful air streams to the sealing silo of the Gas Blowing Machine, this high-speed flow of air forms a drag force on the surface of the cable and pipe, prompting the cable and pipe to move forward. Therefore, the cable a

Comparison of IP transmission technology in cable TV networks Abstract: IP transmission technology in cable TV networks includes three forms: IP over ATM, IP over SDH, and IP over WDM, this article introduces and compares the three IP Address Transmission Technologies in detail. Key words: IP technology, cable TV network, IP over ATM, IP over SDH, IP over WD

In the formation of local area network, in accordance with the general wiring of generic specifications, the construction should be used with "rice standard" network cable or on both sides of the crystal head set dedicated "special-shaped number", and in the cabinet to do with "rice mark" or "Number tube" corresponding to the computer identification record Many units have a small number of original computers, later, gradually added some computers, com

Wireless router Setup is more and more simple, but now is the router installation and network connection is not a lot of netizens. How to connect the router network cable? In fact, it is very simple, today's triple small series for you to share the most common 3 kinds of wireless router cable connection methods. Router network cable How to connect 3

Prepare tools: Network cable, crystal head, crimping clamp, network cable Tester Theoretical Understanding: Differences between direct connection and twisted pair wires Two standards for network cable connection: TIA/EIA-568B: 1, white orange, 2, orange, 3, white green, 4, Blue, 5, white blue, 6, green, 7, white Brown, 8, brownTIA/EIA-568A: 1, white green, 2, gre

More attention should be paid to the standardized installation of category 6 network cable demand At present, although optical fiber has become a buzzword, many related projects are also being implemented. However, due to the technical level, general demand and price factors, it is not possible to form a universal demand product in the market. Currently, copper cables are still the mainstream in network cabling products. The performance of cat5e and

to be converted from multimode to Single-Mode Optical Fiber for transmission. If a digital signal is used, it can be easily transmitted. In a single input and output mode, the optical distribution amplifier can be used to configure the conversion without any baseband signal attenuation during the transmission process. If you have an existing optical fiber installation that needs to be upgraded, consider replacing all the current transmitters and receiving machines with the new digital multiplex

In accordance with the normal application of the topology of computers, routers, cats connected, if the corresponding router LED is not bright, this problem may be connected with the network cable, fault, port failure and other reasons, this article provides detailed troubleshooting ideas. The WAN port LEDs are not lit 1, check whether the WAN port wiring, check and WAN port connection of the cat is power (network

First, the preface In the context of the large increase of global data traffic, data center construction tends to the direction of cloud computing, while the cloud Computing data Center will use 10G, even 40g/100g and other high-speed network applications based on fiber transmission, and the application of virtualization technology also put forward higher requirements for network transmission, Presents new opportunities for the application of optical fiber systems. While China's national standa

After the installation of the cable wiring system, the link transmission characteristics need to be tested, among which the main test items are the attenuation characteristics of the link, the insertion loss of the connector, the return loss and so on. The following is a brief introduction to the measurement of key physical parameters of optical cable wiring and troubleshooting and maintenance in the networ

As we all know, the network cable is one of the most basic hardware facilities for us to access the Internet and the most inconspicuous equipment. We are used to purchasing a ready-made network cable. We seldom care about how the network cable is made. We only know that the network cable must be composed of eight cores

A sound video transmission design is a very important part of the CCTV system. If a set of built systems choose cameras, lenses, monitors, and video recorders that can produce or process high-quality images, but there is no good transmission system, eventually, the images seen on the monitor will not be satisfactory. According to the "barrel rule", the final image quality will depend on the worst part of the entire system, which is often the transmission system. System designers and installers m

Now is a network of the world, the network to hundreds of millions of computers, notebooks, tablets, mobile phones together. The network connection way, divides into wired and wireless two kinds. Wired connections are basically connected by a network cable. So it is necessary to know the network cable. One, the network cable, also known as twisted pa

As an Android technology home, USB OTG is what you must understand, so-called USB OTG is you can use the phone or tablet to charge, and the computer to transfer data from the Micro USB interface to connect other USB peripherals, such as gamepad, mouse, keyboard, The USB stick even moves the hard drive (of course you need extra power). and a USB OTG data cable is a must-have tool.Finished product effectThere is no clear standard for what USB peripheral
