实验名称：TCP/IP Configuration

一、 实验目的

(1) To learn TCP/IP configuration.

(2) To learn the basic command of dos.

二、 实验内容与要求

1. Click Start and then click Run. Type the command or cmd and then press Enter. 2. At the DOS prompt, type NET HELP and press Enter. You should see something like the screen below:

The command you are interested in is the View command. To obtain information about it, type NET HELP VIEW, and press Enter. 3. What is the purpose of NET VIEW:

The NET VIEW command shows the names of the machines present on your network. Lists the names of machines on the left, in column labelled “Server name” and another columns labelled “Remark”

4. List the machines after you have typed NET VIEW from the command prompt HDUSEC-01, HDUSEC-02,HDUSEC-03,……,HDUSEC-48 Close the DOS window by typing EXIT on the command line and then press Enter, or by clicking the Close button in the upper right corner of the window. Obtain the TCP/IP Configuration Information

Use the Start menu to open the Command Prompt, an MS-DOS-like window. Press Start > Programs > Accessories > Command Prompt or Start > Programs > Command Prompt.

The following figure shows the Command screen. Type ipconfig and press the Enter key. The spelling of ipconfig is critical while case is not. It is short for IP

Configuration.

This first screen shows the IP address, subnet mask, and default gateway. The IP address and the default gateway should be in the same network or subnet, otherwise this host would not be able to communicate outside the network. In the figure the subnet mask tells us that the first three octets must be the same to be in the same network.

Note: If this computer is on a LAN, the default gateway might not be seen if it is running behind a Proxy Server. Record the following information for this computer. Record the following TCP/IP information for this computer 6.IP address: 10.1.132.31 Subnet Mask: 255.255.255.255 Default Gateway: 10.1.132.254 Compare the TCP/IP configuration of this computer to others on the LAN 7.If this computer is on a LAN, compare the information of several machines. Record a couple of the IP Addresses:

1) IP sddresses 1: 10.1.132.32
