Realization steps of using sygate to realize the first-line multi-machine Internet-Proxy Server

Now, some families already have more than two computers. If you want to connect more than one computer in an office or two computers in your home to the simplest Peer-to-peer network, you can implement it through Third-party software, such as Wingate, SyGate, WinProxy, and so on. This article introduces using Sygate to realize the first-line multi-machine Internet.

The Sygate software uses the gateway way to make many computers share the ISP account to the Internet, the advantage is that the installation setup is simple, the user hardly needs to carry on the deeper setting, the maintenance management is simple and convenient. Because the Sygate uses the low-level packet exchange technology, so its performance is very advantageous, to the various Internet protocol support is also satisfactory, almost all application software can be used directly. The disadvantage lies in the inability to set different user's permissions and to manage the user more complex. Below talk about how to use sygate software to achieve a small LAN in a telephone line, an account of multiple computer Internet.

　　1. Requirements and installation of hardware

The hardware running sygate requires a generic configuration for computers that can run Windows 9X. But in order to be able to travel on the Internet, the level of hardware naturally higher for better.

Network with a compatible NE2000 ISA or PCI bus network card can be used hub connection and twisted-pair connection, can also use BNC connector 50ω cable Connection, so that each terminal connection.

　　2. Network software Installation of Win9x microcomputer

When you install network settings, you need to add the TCP/IP protocol and the NetBEUI protocol. The Sygate software requires TCP/IP protocol, and the NetBEUI protocol facilitates the installation of Peer-to-peer networks for easy access. Here's how to add a network protocol.

First click Start with the mouse and open Control Panel in the Settings column. Double-click Network, and then check to see if the required protocols are installed. If it is not installed, click "Add ..."; select "Protocol"; click "Add ..."; select "Microsoft" in the left column, select the appropriate protocol in the right column, and click OK. Repeat the "Add ..." option to install all the required protocols.

To return to the configuration menu, you should appear with the appropriate lines tcp/ip→ network adapters, netbeui→ network adapters, and so on.

In order for Peer-to-peer networks to access and share resources, you also need to install network services. Click "Add ..." Click "Services", click "Add ...", select "Microsoft" in the left column, select "File and Printer Sharing for Microsoft Network" in the right column, and press "OK" button to return to network configuration. Press the File and Printer Sharing button, select Allow others to access my files, and allow others to print to my printer.

In addition, network identification is set up for each networked microcomputer so as to facilitate access to each other. In the network configuration of the "Identity" tab, enter the computer name of the machine, such as GW1, GW2, GW3, and other two columns can not be lost. Press OK to complete the Network service configuration.

After the hardware and software installation is complete and properly configured, reboot the machine. Open "Network Neighborhood" on the desktop, you can see the network of each computer. In order for other microcomputers to be able to view the disk files on this computer and to share other resources on this computer, the disk (file directory) must be set up for sharing, allowing other users to access it. Of course, you can set access passwords to enhance security. This enables the Windows 9X Peer-to-peer network to connect successfully. On this basis, the Sygate software is installed again.

　　3. Installation and configuration of Sygate software

Sygate Software (version 2.0 or more) only needs to be installed on a computer that is directly connected to the Internet network and is registered correctly. We call this machine a "proxy host", and other machines connected to this computer are clients. After the Sygate software is installed, the Sygate is first configured through its "Configuration" window. If you set the Enable Dial-on-demand item to indicate that you can detect an Internet connection request with a client and automatically dial up the Internet; through "auto Hang up after XX idleseconds" Set Sygate to automatically cut off dial-up network connection idle time setting; quot; The Start SyGate service automantically "Determines whether SyGate is run as a service. Users can read Sygate's online help to get information about other settings, followed by the need to configure TCP/IP properties for this computer. The specific settings are as follows:

IP address =192.168.0.1 subnet mask =255.255.255.0 gateway = none; DNS maintains its original settings, or enables DNS, host name =host or arbitrary, domain not filled in, and DNS search server order can be added to the IP address of the ISP's server.

The Sygate software does not need to be installed on the client computer, but the TCP/IP properties and network identity of the client need to be configured. Here's how to configure a few items to be described individually:

IP is the network internal IP address, based on the subnet mask and the "proxy host" IP address, such as "proxy host" IP configuration such as before, the subnet mask is 255.255.255.0, starting from 192.168.0.2, Can always be configured to 192.168.0.255, and the subnet mask is 255.255.255.0.

Gateway is the network internal gateway address. In the configuration, you need to add the "Agent Host" IP address;

DNS is the domain name server address. When configured, to enable DNS, host names, can be set to the client's own identity, "domain" is not filled in, DNS search server order to add "proxy host" IP address.

　　4. Configuration and use of application software

Take IE5.0 as an example. The proxy host is still using a dial-up networking connection, and other clients must set up to use the LAN connection. The specific settings are as follows:

Click the Internet icon from the Control Panel to enter the Internet properties settings. Click the "LAN Configuration" button under the Connection tab and select "Automatically detect settings" and do not select "Use Proxy Server".

IE4.0 only need to set up the Internet via LAN. General application software does not require special settings.

First Open "Agent Host", including Modem power. When you install a browser that is configured to start any client after the above steps are installed, the proxy host should be able to dial automatically (dial-up networking is established and username and password set). When a proxy host is connected to an Internet network, it can be browsed from any client computer.
