start of NFS needs to be through the so-called Remote Procedure Call (RPC), that is, we do not just have to start NFS, but also need to start RPC this service is OK! This NFS server can let your PC to the network remote NFS Server share directory, mount to the local side of the machine, on the local side of the machine looks like, the remote host directory as if it is one of its own disk partition slot (partition)! Use the above quite convenient! As shown above, when our NFS server is set up
What is NFS (network filesystem)
Before we start the NFS Setup, let's take a look at what NFS is. It's no use talking about a bunch of them, right. ^_^. The so-called NFS is the abbreviation of network filesystem, which was first developed by the Sun company. His biggest feature is the ability to share individual files (share file) with different machines, different operating systems, and other networks, so you can simply think of him as a file server. This NFS Server allows your PC to share

In the previous chapters you've seen how to initialize connectors and containers and associate them as servlet containers. There is only one connector ahead that serves HTTP requests through port 8080. We cannot add another connector to handle requests such as HTTPS.
In addition, all of the preceding demo programs lacked one thing: the mechanism to start and stop the Servlet container well. In this chapter, we will provide this mechanism as w
Forty-five traditional knowledge of optical fiber and optical fiber cables
1. Briefly describe the composition of optical fiber.
A: The optical fiber consists of two basic parts: the core, package layer and Coating Layer Made of transparent optical materials.
2. What are the basic parameters used to describe the transmission characteristics of optical fiber lines?
Answer: Includes loss, dispersion, bandwidth, cut-off wavelength, and Mode Field diameter.
3. What are the causes of optical fiber a
Multi-port Business terminal MST with factory prefabricated connectors and indoor optical cables are equipped with environment-resistant connectors and adapters in terminals, making it possible to build plug-and-play FTTX infrastructures, and plug-and-play structures can significantly save installation costs compared to traditional optical-fiber continuation methods.

Today, the competition in the access network market is fierce. When deploying fiber-to-Building (FTTP) networks, it is usually difficult but necessary to make a budget early. This is because business providers should not only consider the initial installation fee, but also the unexpected business operation and maintenance costs. A large number of cost budget models prove that in the design and construction stages, the correct method for connecting FTTP networks in different segments is more accu
solution.Many enterprises adopt multiple technologies based on their actual application needs. For example, some enterprises use epoxy/polished optical fiber connectors in indoor installation layout, while non-epoxy/non-polished optical fiber connectors at the egress end. Similarly, non-epoxy/non-polished optical fiber connectors are provided to professional tes
Multi-port service terminal MST with factory pre-fabricated connectors and home optical fiber cables are equipped with environment-resistant connectors and adapters on the terminals, this makes it possible to build an out-of-the-box FTTx infrastructure. Compared with traditional fiber connection modes, the plug-and-play structure can significantly save installation costs.
Today, fiber-to-user FTTP network d
The main role of a JMS broker such as ActiveMQ is to provide a communicationInfrastructure for client applications. For that reason, ActiveMQ provides connectors,A connectivity mechanism that provides client-to-broker communications (usingTransport connectors) as well as Broker-to-broker communications (using networkConnectors). ActiveMQ allows client applications to connect using a variety of protocols,But

To ensure optimal throughput and minimal resource utilization, each map task performs this data transfer through multiple transactions.Figure 2:sqoop Export OverviewSome connectors support temporary tables to help isolate production forms that result from job failures caused by any cause. Once all the data has been transferred, the data in the temporary table is first pop

Integrated wiring is a modular and highly flexible information transmission channel between buildings or architectural complexes. It enables voice, data, imaging, and switching devices to connect with other information management systems, as well as external connections. It also includes all cables and related connection parts between the connection point of the building's external network or the telecommunication line and the application system equipment. Integrated wiring consists
installed in Linux has been completed, local connection MongoDB has also been successful, then we have to consider another problem, lan how to connect MongoDB it. How do Windows machines in the LAN connect to the MongoDB in the Linux machine?
In fact, the practice is just as simple:./mongodb/bin/mongo 192.168.10.234:port.
But notice here, we need to open the MongoDB port number on the CentOS, and then we'll talk about how to open the specified port on the CentOS.
We open the configuration file/
need to be aware that we need to CentOS on Open MongoDB the port number, next talk about how to CentOS Open the specified port on the ?We open the configuration file /etc/sysconfig/iptables , add the following to the file:?-A rh-firewall-l-input-p tcp-m TCP--dport MongoDB Port number -j ACCEPT?Then restart the service?Service Iptables Restart???at this point, you can begin to access it over the LAN CentOS on the deployed MongoDB???By the way, add a little bit more CentOS with the Windows Exchan
