Next, we will deploy the local exchange first. It is very easy to deploy exchange in a clean single-domain environment. Here we will deploy two CAS servers for NLB, two mailbox servers are used as the Dag, and an edge server is added. The reverse proxy is assumed by TMG. the preparations we made earlier are different based on the installed roles, this should be taken into account. Today we will deploy two C

Before talking about this topic, let everyone know what a server is. In the middle, the role of the server is synchronization, and some active behaviors of the broadcast and server, such as the weather, npc ai, etc, the reason why many online game servers need to carry some game logic operations is to prevent client cheating. With this understanding, this series of articles will be divided into two parts to talk about the design of online game

Background:Our server environment, is the ESX server, which ran dozens of virtual servers. Most of them are virtual Windows servers, and then each application will have several app servers and then install WebSphere to build cluster to support the Web server, both IBM HTTP server and IIS.The environment is like this, this time for a region of the server cluster t

Brief introduction In most companies, system administrators are required to do more with fewer resources. With virtualization technologies such as IBM PowerVM, the number of IBM AIX instances that system administrators must manage has grown significantly. PowerVM supports running dozens of or even hundreds of IBM AIX logical Partitions (LPARs) on a single hardware. Many years ago, a system administrator might be responsible for managing only more than 20 instances of AIX, and in today's environ

Five Measures to Ensure the Apache security of Web servers-Linux Enterprise applications-Linux server application information. For details, refer to the following section. Source: Saidi net Author: freedom Needless to say, an important reason for Apache to take over half of Web servers is that it can provide a secure Web operation environment. The Apache community has done a lot of work to ensure its secur

Basic Security reinforcement for Windows ServersMeituan cloud (MOS) provides cloud host servers for Windows Server 2008 R2 and Windows Server 2012 R2 data centers. Due to the high market share of Windows servers, there are a large number of malware such as viruses and Trojans targeting Windows servers, which are easy to obtain and have a low technical threshold.

Security is more important than anything else. Your company must have run important functions or saved important confidential files on Windows servers. How can we ensure their security? So don't put the data in a relaxed state of security measures. This article recommends 10 tips to improve the security of Windows OS servers. 1. log out-- It is best to leave the system for a server that is not frequently u

Analysis: event records of one intrusion into Linux servers This vulnerability is common in ColdFusion and content management systems. In some cases, a specific attack may succeed, and a high-value server may cause significant data leakage. In other cases, attackers can operate infected hosts on a large scale. Recently, I noticed that multiple IP addresses were attempting to exploit a PHP vulnerability, So I recorded the results using a honeypot. Thi

Recently, I learned the expect scripting language through mongoingshortct books. This scripting language is an extension of the tcl language and is used to solve the problem that some tools cannot automatically interact with each other. For example, when logging on to ssh, you cannot specify a password in the command. The following is a simple example of managing multiple servers using reverse CT: 1 Recently, I learned the wide CT scripting language t

kernel is run. However, the more CPUs are installed, the fewer performance improvements are obtained from hyper-threading. In addition, the Linux kernel recognizes multi-core processors as multiple separate CPUs. For example, two 4-core CPUs are treated as eight single-core CPUs in the Lnux system. however, from the performance perspective, the two 4-core CPUs and eight single-core CPUs are not exactly equivalent. According to the test conclusion, the overall performance of the former is 25% ~

For most modern enterprises, data security is equally important as physical security. Think about all the important business information, intellectual property rights and customer data stored on the server. You will not leave the materials on your desk without locking the door. Therefore, you cannot store the data on your server, but do not take adequate security measures. Most of us know how to use firewall and anti-virus software to protect our computers. However, we may not know how to fully

With the development of Internet information technology, computers have been applied in all corners of the world. Many enterprises rely on IT technology to build their own information systems and business operation platforms, and provide services to many customers through one or more servers. This method has brought a lot of convenience to people, however, this open environment also increases the risk of information security and easily leads to inform

Windows File Servers play a vital role in the network. They carry sensitive files, databases, passwords, and so on. When the file server goes down, the network is likely to be paralyzed. If they are damaged, it is equal to opening Pandora box. The following is a real case of hacker attacks on the file server. Share with you the situation and how these vulnerabilities are exploited to damage the system-from the perspective of a hacker. This will help y

How to Learn about Linux servers? -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. I am a freshman majoring in computer science and want to develop in Linux servers in the future. I have a few questions. 1. Now I can only build most of the servers on RHEL5, with some basic network configurations.

servers; We all know that each machine in the Windows network can be a file sharing server or a client, and Samba can do the same, for example, a Linux machine, if the Samba server is mounted, it can act as a shared server, and can also be used as a client to Access Windows shared file systems in other networks, or other Linux sabmba servers; In Windows network, we can see the shared file function, we can

To provide comprehensive security protection for Web servers and applications in the organization's company's Intranet, every Microsoft Internet Information Service Server (IIS server) should be protected) and each Web site and application running on these servers is not infringed on the client computers that can connect to them. In addition, the Web sites and applications running on all these IIS

PHP allows multiple servers to share SESSION data. 1. websites with a slightly larger problem generally have several servers. each server runs modules with different functions and uses different second-level domain names, for a website with a strong integrity, the user system is unified, that is, a set of user names and passwords can be used to log on to all modules of the website. Each server shares user d

When a transaction release is created and an error occurs during initialization, view the agent information as follows: Log Reader Agent error: Status: 0, code: 20015, text: 'remote server "serverName" does not exist, is not specified as a valid Publishing Server, o

Technical support analysts often complain about high server loads. In fact, cPanel software and its installed applications rarely cause high server load. The server owner, system administrator, or server supplier should conduct a preliminary investigation on the high load status, and seek help from analysts after confirming that the situation is complex. Why is the high server load? Excessive use of the following items will directly cause high load problems: CPU Memory (including virtual memo
