discarding the hardware, you should follow some of the advice and advice given below.
Feasible disassembly and modification scheme
Many companies have made the mistake of discarding the old server in a corner, which is bad behavior anyway. From a security point of view, the data is easily stolen, the server is easily stolen. Equally important, the value of the server has been lost over time, and the unused servers can be retrofitted to a new office,
When using a linked server (Linked Servers), the most expensive cost is the transmission of large amounts of data between network bandwidth. It is important to write the correct code on the correct server, because each error can cause a very expensive cost to the network bandwidth. Here are a few common errors when using a linked server (Linked Servers):1: Use push method instead of pull method to fetch num

Article Title: Application of Linux cluster technology in Web Servers. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Introduction
The popularity of the network has led to a sharp increase in the traffic of various e-commerce and e-government websites. The system bottleneck problem has become increasingly serious,
As we all know, servers are the most important resources in computer networks and have high security requirements. If the running server is not properly configured, a large amount of useful information may be leaked, so that hackers can damage your network. Therefore, we should check the server to ensure that hackers cannot obtain the key information they need.
Today, almost every organization is running DNS serve
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

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.
