The premise for the commercial use of IPv6 is that IPv4 addresses are exhausted. For this reason, we urgently need the IPv6 protocol to improve this situation. So how does IPv6 distribute DNS servers? Next we will analyze the principles in depth. Hope to help you. What is the architecture of the IPv6 Domain Name System? The DNS in the IPv6 network is consistent with the IPv4 DNS in the architecture and uses a tree-like domain name space. The differenc

contained in the domain except for the subdomains that are proxies to other places. if the subdomain of the domain is not proxies, the region contains the subdomain name and data in the subdomain. DNS defines two types of domain name servers: primary Master and secondary Master. the PM Domain Name Server obtains the data of the zone it is responsible for from the files on the host it runs, the SM Domain Name Server obtains data from other domain name

For Linux users, You must select seven servers-Linux Enterprise applications-Linux server applications. For details, refer to the following section. Source: 51CTO System administrators who need a Linux system often need to purchase a bare metal system and install Linux on the system in their own way. After all, Linux users are Maverick and radical. They have different ideas. They manage servers in differen

service quality of the Media Server. Therefore, the Streaming Media Server is the basis of the streaming media application system and the most important component.Streaming Media Servers: High-concurrency video servers, live streaming time shifting servers, P2P live broadcast servers, and video interaction application

Problem 1. Automatic Backup between two servers How to implement automatic backup between two servers is a common problem for network administrators. For example, we need to automatically back up important data under the specified directory in server A to a specified directory in server B at night or when the server is relatively idle. 2. Back up data to different directories every n days Sometimes, we may

How DHCP servers work Key points of this Chapter The working principle of the DHCP (Dynamic Host Configuration Protocol) server. Install the DHCP server. Troubleshooting of DHCP servers. DHCP is used to automatically provide IP addresses, subnet masks, and route information for computers. Network administrators usually assign IP addresses in a certain range to distribute the IP addresses to clients on the L

Connect two asterisk servers There are two asterisk servers. You can call the extension number registered on the other server. Assume that there are two servers A and B. Extension A starts with extension 3, such as 3000. Extension B starts with extension 8, such as 8000. Create an IAX trunk on a and name it "interoffice". The configuration is as follows:"Pee

NFS servers are widely used. This service is required for file sharing in many communications. Today we will explain how to build and use NFS servers in multiple systems. I hope to help you understand this aspect. NFS Introduction Developed by SUN, NFS has become a standard for file services (RFC1904, RFC1813 ). its biggest function is to allow computers of different operating systems to share data over the

PHP allows multiple web servers to share SESSION data. I. websites with a slightly larger problem usually have several servers. each server runs modules with different functions and uses different second-level domain names, while a network with a strong integrity I. problem originWebsites with a slightly larger size usually have several servers. each server runs

You can use the following procedure to install Active Directory (R) Certificate Services (AD CS) and to register the server certificate on a server that is running Network Policy server (NPS). If you deploy certificate-based authentication, the server running NPS must have a server certificate. During the authentication process, these servers send their server certificates to the client computer as proof of identity. (if NPS and ad are two

How to install and configure a MySQL Cluster Mysql Cluster based on two servers This article describes how to install and configure a MySQL Cluster based on two servers. MySQL can continue to run when any server encounters a problem or goes down. Note! Although this is a MySQL Cluster based on two servers, there must be an additional third server as the managem

other institutions may also have similar needs (very similar to "book Dealers" Amazon?) ), and was bornThe release version of Ironworker. Of course, the Ironworker starter version uses Ruby and the rails-based API. At first, Ironworker performed very well, with little effort and time to support the heavy load. Soon, however, Ironworker was constrained by rails. It's another ror. To keep the service flowing, Iron.io keeps its server CPU usage at 50-60%;CPU usage once it exceeds this range, it in

Multi-Point SSO, which can be understood as SSO with multiple registered servers or distributed SSO, that is, the user registration information is distributed across multiple servers, in fact, this type of technology is relatively mature now, such as Tencent, skepy, interconnected star, and other large-scale applications. For example, the number of Tencent is hundreds of millions, if one server is used for

The emergence of cluster technology and the rapid development of IA architecture servers provide new choices for social needs. It is cost-effective, easy to use and maintain, and cluster technology can be used to construct a supercomputer. Its super processing capability can replace the expensive large-scale computer, it has opened up a new direction for high-end applications in the industry.Cluster technology is a relatively new technology. With clus

soon to graduate, but also to start looking for a job, the university wrote so many code, but not a good summary of the commonly used concept is a pity amount, through this blog record my most commonly used knowledge of the good. When it comes to Web servers, there are a lot of articles are introduced very well, before I saw a very good, to my help is very big, but now can not find the original text, see the blog is reproduced in the park, I am here a

Server Design technology has many, according to the protocol used to divide the TCP server and UDP server. The loop server and the concurrent server are divided by processing mode.1 loop server and concurrent server modelIn the network program, in general, many customers correspond to a server, in order to deal with customer requests, the service side of the program has put forward special requirements.Currently the most commonly used server models are:• Loop server: The server can only respond

Web project deployment to Tomcat in addition to the Eclipse plugin, Eclipse also has a servers window to deploy. Issue background: Servers window, I previously created a tomcat v6.0 Server, then I deleted the auto-generated project servers, and changed the tomcat path configuration in eclipse (because I deployed it with the configuration file server.xml). The pro

This paper briefly introduces how to extend the console of Linux server through the common COM port, which is practical and simple, not limited by the server network, and can easily manage the Linux server in the actual production environment. When it comes to managing Linux servers, there are many different ways to do this: Keyboard + monitor, Web Landing, web-based tools, graphics tools under X system, and so on, which is not a problem on a regular
