Network construction

Two key router functions and technology (1)



In recent years, abnormal development of the Internet rapidly growing commercial applications, the development of the Internet users is difficult to predict. In addition, more and more users need high-speed access. The data indicate that in China, Internet users complain about slow is the first of many problems. Therefore, improving the network bandwidth, network quality of service, router, network management system becomes increasingly important. The premise of guaranteeing quality, maximize the use of bandwidth, early detection and diagnosis of equipment failures, quickly and easily change the configuration required network management functions into the network directly affects the interests of users and network operators an important factor. Generally speaking, the structure of the router is moving faster, better and easier to service quality integrated management of three directions.

Xiang Jie Windows Server 2008 Security Log



To establish a secure logging

To give an idea how to track the computer security log feature specific aspects, first need to know how to start the Security Log. Most Windows computers (except for some versions of the domain controller system) by default, not to the security log (Security Log) start logging information. This setting positive and negative, aspects of disadvantages is that, unless the user force the computer to start the log to log security events, otherwise we could not conduct any follow-up. The good news is that the log does not occur in the problem of information and tips packed full of the error message log, which is Windows Server 2003 domain controller without any warning, under the act.

Domestic Server pole vault


Technically speaking, 64-bit, dual-core and a series of new technologies to the last couple of years of PC server into a lot of fresh blood, but in the Chinese server market, has always been known for in the domestic PC server vendors are not many servers demonstrate their vitality. However, we have been successively come out to see some domestic manufacturers to high-end RISC / Unix areas of strong words: Jan. 20, the dawn of the Great Wall Hotel is proud to announce the second generation of AMD Opteron-based RISC minicomputers to declare war; February 22, Pao-technology is also co-Le Bourget, France, Intel Itanium-based 8 ~ 32 PowerScale series high-end server to attack the RISC camp.

EastFax fax server system in the French CMA CGM (China) Ltd. The successful application of



Background

Logistics industry is at the lowest cost, through transport, storage, distribution, etc., to achieve raw materials, products and related information by the flow of goods to the consumer to the origin of the industry. With the coming of information society, information has become a major feature of modern logistics. It requires supply chain, enhance the communication between the various segments together to reduce cost and improve efficiency. So fax as the modern enterprise is one important way of communication, the development of the logistics industry has an essential role in nature. However, with the rapid development of the logistics industry, the fax volume of explosive growth, continue to highlight the disadvantages of the traditional fax machine, it can not be achieved not only by fax send and receive large capacity and stable, but costs are prohibitively high, so a more stable, efficient and economic emergence of the fax came into being.

How the composition of the router router architecture



How it is composed of router? This question first about the architecture from the router.

Broadband Internet dial troubleshooting and optimization (3)



Starting from the set, the degree of intelligence to improve dial-up

Multiple computers to share broadband, "cat" in the case of dial-up, only the first broadband "Cats" by the computer for manual dial-up connection, wait for dial-up to normal after the success of other computers online. In fact, as long as the broadband "Cats" by the computer system even look set correctly, can allow other computers can dial locally, and the following settings are specific steps:

Develop annual business goals, business executives will be troubled by some annual business goals, especially for those who are emerging markets, or business instability, influenced by the market environment of the industry is particularly keen; the end of the year, business seems to be unreasonable performance targets as early as expected, the executives as appropriate to each plug a red envelope, performance evaluation methods illusory, and may even lead to executive turnover.

Intelligent Building Cabling System




First, structured cabling and wiring of the more traditional

Currently, more and more towards the construction of domestic buildings modern and intelligent direction, and for a building, whether it can be an intelligent building, ultimately depends on whether the buildings have a complete, high quality and meet international standard cabling system. In the past, building wiring subsystems are independent, and different transmission media, but with the telecommunications industry and the rapid development of computer systems, traditional communications and computer cabling no longer meet the demand on the transmission line. Specific performance:

Advanced techniques for network cabling network unimpeded Internet cafes



Internet cafe operators, whether or general network management, control wiring methods and techniques are necessary. To some extent, network cabling technique is to measure the level of an Internet cafe important aspect of network management technology. Very often, we feel that as long as the cable can connect to, so the network can be used on the line.

Solaris Unix to configure one network card Router



We generally believe that the router connected to multiple networks, so it should be corresponding to each network has a network card and an IP address. However, in practice may appear to be constructed on an internal network to solve the Internet's IP address was not available, the workstations are in their own board have also integrated a network card. How to use the resources available to set the router then? Seems easy to get, but in fact a single card can also be paired workstation TCP / IP network routers. In the SUN workstation with Solaris2.x operating system, you can use the following method to configure.

Windows Server 2008 share the obstacles to clear



Many people think that access to shared resources is very simple, as long as the first to find shared resources, and then double-click the shared goal, and then log into you can visit to operate. In fact, every step of the operation of which may be subject to restrictions on Windows systems; it does not, when we try to access Windows Server 2008 system to share resources, the system on a link on each of these obstacles, we must reasonable remedy to set in order to clear obstacles, to share access along the green light.

SMTP server settings in the user name and password



To prevent spam, you can set the list to allow only allows 127.0.0.1, thus preventing spam, and do not need to fill in your username and password to send mail, but some programs / code without a user name and password are unable to send a message , and did not secure without a password. So we should set the SMTP server, click the user name and password.

Set the threshold to prevent DDoS attacks on routers



First, prevention of DDoS Attacks

In a distributed "denial of service" (DDoS) attack the process, a group of malicious hosts or hosts infected with malicious hosts will attack the server to send large amounts of data. In this case, near the edge of the network nodes will become depleted. For two reasons: First, the nodes near the server is usually only required when dealing in the design of a small amount of user data; Second, the core area because of data aggregation in the network so that marginal node will receive more data. In addition, the server system itself is also vulnerable to attack, in extreme cases be paralyzed overload.
