Managed and leased operators should pay attention to the problems and suggestions



Rent server hosting server and open up business, mainly on the specific details of the hardware and software to meet customer requirements. At present, the domestic rental server managed server and the situation is probably as follows:

Server hosting server and hire a number of problems

1. Customers to their problems

Client to server hosting to IDC, the management server is basically managed remotely by software, can be understood, the server hardware hosting service provider to the IDC, IDC need to provide network resources, power, security and other basic services; the server operating systems, application software services part of the stability and security in all of them in the hands of customers, IDC service providers with no direct relationship. Therefore, the server in the IDC problem, largely because the customer's own operational errors caused by the accident.

2.IDC service provider's network fails

Various IDC network services still exist some problems, and backbone operators link line does not have enough redundancy, if compared with other major Internet service provider ChinaNet connection line fails, then the whole network all the possible disruption To enhance the anti-risk ability, must be connected to multiple backbone carriers, even if a certain line problems, through other networks to provide services can also be normal.

If the IDC service provider's network problems, or network interruption, and the server itself has no direct relation, when the circuit returned to normal after return to normal access.

3. Application system can not function properly

Client to server hosting to IDC, will run multiple applications on the server services such as WWW service, Mail service, Ftp service, etc., but also dynamic data like a database query service. Type of service provided by more the greater the impact on the server, if access to the server is too big, the greater the likelihood of problems, it is best to allocate resources efficiently, to avoid a server too much to bear traffic. If a service does not start, you can remotely restart the service; occur if the server crashes, it immediately so that IDC service providers on duty restart the server to release resources to achieve the purpose, after a reboot or related treatment you can quickly return to normal.

4. Technical capacity, misuse or non-standard operation

Client server, poor management, if the technical staff of the technological strength is not good enough, you may be wrong on the server operation or operation is not standardized, resulting in the server can not access.

5. Safe, hacker intrusion

Server has been penetrated by hackers or malicious attack, or sudden large server traffic, it will adversely impact the server, or even a vicious incident.

6. Server aspects of the fault

Server, problems may arise where, mainly memory, hard drive, applications and so on. Designed to be unreasonable if the IDC may be bad because of heat, there CPU downtime due to excessive heat; if memory compatibility is not good, it will affect the server performance degradation, such as dust, static electricity, air circulation, wind problem affect the normal operation of the server.

Rent server hosting server and the problem solution

1. Learn more about servers, providers, etc.

Managed services customers need before, will consult various aspects, including understanding the background of service, price, service quality, server performance and other information and data, sources of information through newspaper advertisements, Internet, friends and co-operation partners. Enterprises in the purchase of a server as far as possible to understand the server's expert advice before buying in determining what to pay attention to understand clearly, and then decide what to buy the brand and performance of the server.

2. Outsourced to professional service organizations

If there is demand for business, I can allow professional service providers to be responsible for procurement, outsourcing to a unified company, responsible for the procurement of hardware, software purchase and installation, system development and debugging, custody and maintenance of a range of services, this can be as much as possible to avoid the purchase is not suitable for their own servers and related products and services losses. Server in the purchase process needs to consider many factors, but the most important application is based on business requirements to select their own server configuration standards, not everything needs the best, most expensive products. To meet their own needs, but also a lower investment and ensure that the server normally, and stable operation, is the best server.

3. Server vendors to provide solutions

Server manufacturers have a variety of solutions, there are variety of server is completely designed for users of products IDC, the original structure and configuration of the server some adjustments would be more suitable for current users. IDC user applications include WWW, Mail, Ftp, and database query services. Server vendors to provide better products, the part of the application software pre-installed on the server, to provide customers with a package of solutions, so companies can expand server sales, but also to solve the practical difficulties encountered by customers.

4. By providing a platform for IDC services, server and other resources available to the client companies

IDC business from the current development trend, the server hosting the proportion declined steadily, and this contrast is the proportion of rented servers to grow rapidly. Basically, the current IDC service providers have launched a server rental business and the price is very cheap, the customer does not require any hardware and software investment, just a one-time capital investment that can enjoy high-speed broadband access, software and server rental, value-added services, applications, rental and other services. IDC service providers are already aware of the current development trends, to hardware manufacturers, software vendors, application service providers together to provide customers with a comprehensive service platform. Enterprises to choose a server problem needs only themselves, by the IDC service providers by adjusting the data to meet customer demand, this service model has been in ChinaNetCenter good practical application.

Do not Ping My Computer


To find objects in the hacking, most use Ping command to test the host, if Ping barrier, the level of bad "hackers" will quit most. In fact, can create a false impression, even if we are online, but can not be connected when the other Ping This can avoid a lot of attacks.

The first step: Add Standalone Snap-in


Start - Run, type: mmc, start to open "Control Panel" window. Then click "Control Panel" menu under "Add / Remove Snap-in", click "Add" button in the pop-up window, select "IP Security Policy Management" item, click "Add" button. In the Open window, select managed objects for the "local computer", click "Finish" button, and close the "Add / Remove Snap-in" window, return to the console.



(Figure 1)

Step two: Create IP Security Policy

Right-click the newly added "IP Security Policies on Local Machine" (Figure 2), select "Create IP Security Policy", click "Next" and then enter a policy described as "no Ping" (Figure 3). Click "Next", select "Activate the default response rule to" restore options, click "Next." Began to set the authentication mode, select "This string is used to protect the key exchange (preshared key)" option, then enter some random characters (the characters following will be used) (Figure 4). Click "Next", will be prompted to complete the IP security policy has been confirmed to select the "Edit Properties" check box, click the "Finish" button, will open its Properties dialog box.

(Figure 6) Click "Next" and select "All network connections" to ensure that all computers are Ping unreasonable. Click "Next", set the authentication method, and as the third option above, "This string is used to protect the key exchange (preshared key)" and fill in with just the same content.
