1, Linux network interface of literacy(1) Naming of network interfacesThere is no naming convention, but the definition of a network interface name is generally meaningful. For example:Eth0:ethernet, typically used for Ethernet interfaces.Wifi0:wifi is a wireless LAN, so wifi0 generally refers to a wireless network interface.Ath0:atheros, generally refers to the Atheros chip contains the wireless network interface.A shorthand for lo:local, generally referred to as a local

A few years ago, people thought that the unshielded twisted pair copper cable had reached its limit in the fifth category of MHz. Many users and manufacturers turned their attention to the optical fiber and thought that the optical fiber is an inevitable transitional path for IT facilities. The optical fiber solves the disadvantages of unshielded twisted pair wir

Nowadays many people's life can not be separated from the computer, as the High-tech products of the computer also does for people's lives added a lot of color, but also brought some knowledge problems, which for those who do not understand the computer knowledge of the netizens is a big trouble. It's like setting the loopback interface in a win7 system and installing a problem where the specified file cannot be found, so how do you solve it? Let's go

23: Two-dimensional array loopback traversal View Submit Statistics Questions Total time limit: 1000ms Memory Limit: 65536kB Describe Given an integer array of row row col columns, requires starting from the array[0][0] element, and pressing the back shape to traverse the entire array in a clockwise order from outward. ：

1. If nodejs is not installed on Linux, first install nodejs 2. Install loopback npm install -g strongloop 3. Create a project slc loopback// Create your project [?] Enter a directory name where to create the project: my-new-project [?] What‘s the name of your application? my-new-appcd my-new-projectslc loopback:model // Create your first model [?] Enter the model name: my-model // Name the mod

1. About the digital loopback mode In the digital loopback mode, the receive signals are connected internally through Multiplexers to the corresponding transmit signals. This mode allows testing of serial port code with a Single DSP device; the McBSP records es the data it transmits. 2. About the Clock Stop Mode The clock stop mode supports the SPI master-slave protocol. If you will not be using th

Sometimes a standalone block device is required, and loopback is a convenient option to create the following waysDD If=/dev/zero of=./loopback_file bs=1m count=1000losetup/dev/loop0./loopback_fileFirst set up a file of the specified size as the actual storage space, and then associate it with/DEV/LOOP0, the loop device seems to have a number of restrictionsYou can create a file system on it after the creation is complete, etc.When you need to remove,

I. Optical Fiber1. OverviewThe optical fiber is similar to the coaxial cable, but there is no mesh shielding layer. The center is the glass core of light transmission. In multimode optical fiber, the core diameter is 15mm ~ 50mm, roughly equivalent to the hair width of a person. The diameter of the Single-Mode Optical Fiber Core is 8mm ~ 10mm. The outside of the

function, then the LAN port to do the configuration on it, after this operation, traffic is led to the Web server, that is, the second picture in the article shows the flow process, At this point, the reason for the failure is that the Web server responds directly to the request of the client, if the reply data of the Web server is passed through the firewall again, and the Dnat map restore operation can be done, we configure the LAN port Snat to implement, the configuration is as follows (othe

Ive found this very handy .. recently, I was working on a server and we were trying to access the local SharePoint site http: // 127.0.0.1 or http: // nameoflocalserver/pages/default. aspx and I was constantly prompted for the username and password. in SharePoint 2010 it can really annoy you by not accepting your Username Password credentials in the popup window. Its a 'feature 'on the server that you need to disable as a workaround .. You wowould need to create a DWORD registry key in the r

After the system is reinstalled and ADT (ADT-bunlde-Windows) is used, a ddms initialization error always occurs, and logcat cannot obtain the log. The error message is: Failed to initialize Monitor thread: unable to establish loopback connection The actual problem is that the ADB process cannot be started. The following error message is displayed when you use ADB devices on the command line: * Daemon not running. Starting it now on port 503

From: Http://wiki.wireshark.org/CaptureSetup/Loopback @ ++ Alternatives A required cial network sniffer called commview (from tamosoft) allows to capture packets on the localhost network adapter but it dissects fewer protocols, so you can capture packets with commview and save them into a file and open it with Wireshark. An other alternative is to add a route to your local machine going through the Network Gateway: Route add Wit

There are several virtual machines on the local machine. To allow virtual machines to communicate with each other without a network, you need to add a network adapter for Microsoft loopback adapter. It is easy to add in XP, and it takes a long time for me to find it in RC, I don't remember what I clicked during the search process, and the location I already looked for was reversed.
