In Linux, The SoftEther server is set up to interconnect the two Intranets-Linux Enterprise Application-Linux server application information. The following is a detailed description. By: wheel Linux environment requirements, installation method, startup method, Operation/Management Method 1) work environment requirements Linux SoftEther runs in the following environment: Pthread Library OpenSSL library ( It also needs to be able to identify the Linker of *. a file format (compressed static lib

Hub (Hub) A hub is a machine that centralizes a network of cables, which is a connector for multiple hosts and devices. The main function of the hub is to connect the received signal to the synchronous shaping amplification, in order to enlarge the transmission distance of the network, is a form of repeater, the diffe

need to transfer data through a hub or vswitch. However, when connecting two NICs, you cannot directly use the express Connect line, but you must use the cross-type network line. When creating a cross-type network line, you must use the T568A line sequence to connect one end to the other, the other end uses the T568B line sequence connection. If the crossover network cable is not created in accordance with such standards, even if the two computers ca

Zheng @ playpoly SR 20090924 KANG Ye posted two tutorials on getting started with pubsubhubbub, PubSubHubbub working principles and usage, and [tutorial] how to use the PubSubHubbub protocol. Here are some additional points: 1. About subscription expiration and automatic subscription Refresh: The first Request "Subscriber Sends Subscriber Request" (Subscriber --> Hub) is a Subscriber Request, which is called the second Request "

The HITS (Hyperlink-Induced Topic Search) algorithm was first proposed by Dr. Jon kleberger of Cornell University in 1997, part of the "CLEVER" Research project for IBM's Almaden Research Center. The HITS algorithm is a very basic and important algorithm in link analysis. Currently, it has been used as a link analysis algorithm by Teoma search engine (www.teoma.com. 1.

hubs Hub is the basic equipment in data communication system, it is a kind of hardware device that does not need any software support or only rarely manages software management, just like the transmission medium such as twisted-pair wire. It is widely used in various situations. Hubs work in a local area network (LAN) environment, which, like a network adapter, is applied to the first layer of the OSI Reference Model and is therefore called a physica

undertake this task, That is the selenium-server in selenium2. Selenium-server supports the call command to receive remote scripts, and then operates the browser on its host to perform the task of testing remotely. Of course selenium-server in order to be compatible with SELENIUM1 scripts, it also supports SELNIUMRC supported features "that can receive SELENIUM1 call commands". The code that calls the remote machine to execute the test locally is this:Import Org.openqa.selenium.*;import Org.ope

Selenium Grid2The grid allows you to establish the primary node (hub) and branch node (nodes) on different hosts. The test cases on the master node are run on different branch nodes, so that a different environment can be set up to allow a test case to complete validation in different environments. The Selenium Grid2 has been integrated into Selenium server (Selenium-server-stanalon-xxx.jar package).9.1 Selenium2 Working principleSelenium2 because of

Selenium Grid supports distributed testing, allowing testers to test in a distributed environmentIn general, consider using the selenium Grid when you are facing:1. Test multiple versions of multiple browsers or individual browsers, or test various browsers on different operating systems2. Reduce test suite run timeThe Selenium Grid contains a hub and at least one Node, both of which can be started by the Selenium-server-standalone.jar fileDeployment

HubA hub is actually a multi-port repeater. Hubs generally have 4, 8, 16, 24, 32, and other RJ45 interfaces. Through these interfaces, the hub can then complete the "relay" function for the corresponding number of computers (sort out the signals that are not completely degraded, generate a complete signal again, and then continue to transmit ). Because it is in a "center" position in the network, the

To run Webdriver with multiple threads concurrently, you must satisfy 2 conditions at the same time, first of all, your test program is multi-threaded, and then you need to use selenium Server. Download locations such as:After downloading it is a jar package that needs to be run on the command line. There are 2 things inside: Hub and node. It can be understood that the hub is a thread pool running on a serv

In a distributed system, in addition to common end-to-end communication, there is also one-to-many broadcast communication. When it comes to broadcast, it may be reminiscent of IP multicast or IP multicast. This is not the topic of this article. This article will talk about TCP-based application layer broadcast. As follows: The rounded rectangle represents a program. "Hub" is a service program, not a network Hub
