Cost-effective use of "Spider" to help you achieve multi-network parallel (1)

Many organizations, schools, and enterprises have established multiple networks to facilitate their online work. For example, they have applied for broadband services in addition to the education network, some enterprises have also applied for two network services: China Telecom and China Netcom, which facilitates access to resources in different network environments. If there are too many network lines, it may be inconvenient. For example, the intranet resources of CERNET cannot be accessed using Netcom broadband, and the resources on the server downloaded using Telecom broadband are too slow. In this way, some users can only switch between the two networks by changing the network cable connection and modifying the IP address to access the desired network, which is very troublesome to operate, the cost of purchasing a professional hardware router is too high. In fact, we can use an old computer to build a software router, which saves both costs and solves the problem of multi-network parallel.

Preparations before vro Construction

The benefit of choosing a software router is that it can greatly save costs. The software routing system has very low requirements on the system. If there are used computers in the office, we can use these computers to build the software routing system without buying new ones.

We should also pay more attention to the choice of the routing system, because this router system is generally used for enterprises and Internet cafes, the system must have a strong stability, so it is best to use an independent routing system, do not use the routing software installed on the operating system. For example, Windows has many vulnerabilities that need to be continuously patched to improve. If you choose to install vro software on the system to build a routing system, not only security is not guaranteed, but also frequent patching will be very troublesome.

Now there are many independent routing systems based on Linux. This system inherits the features of high Linux efficiency and strong immunity, and is suitable for creating a stable software routing system. Here we will introduce a Chinese-made routing system, the sea spider. In addition to setting up the routing system we need, the most important thing is that it has a completely free version, it can fully meet our daily application needs, greatly saving money.

To build a software router, we need to prepare two aspects in advance.

1. COMPUTER: The computer is used to install the sea spider routing system. The computer hardware configuration is not too demanding. Generally, the old computers eliminated by the organization can have a CPU of no lower than 486 ). If dual-line parallelism is implemented, three Mbps NICs should be installed on the computer. If three-line parallelism is implemented, we need to install four NICs, and so on.

2. router system: Hi-Spider Router is a dedicated Router system that can switch between multiple networks, sea spider routing is widely used in enterprises, homes, community networks, and other places, especially in high-traffic network environments such as Internet cafes and schools.

Setup steps with me

I. system installation: Installation of ISO image burning

Hi-Spider Router is a Linux-based independent operating system that requires an exclusive disk and cannot be installed on an existing operating system. We need to prepare a hard disk without data, during system installation, the installation wizard of "sea spider" Will repartition and format the hard disk. Before installation, log on to the terminal. Use a CD to install it in DOS.

During installation, first place the installation disc into the computer's optical drive and restart the computer to bring up a running menu 1 ). Select the first "normal installation mode" to go to the main installation page (2). On this page, select "Install spider route free version)". The installer automatically performs hardware detection, then initialize the hard disk and install the system. After installation, the system restarts automatically.

TIPS: the installation of the routing system takes about 1 minute, and the space occupied after installation is only 33 MB. Every step of installation has a very detailed Chinese prompt, the installation process is not described in detail here.
