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 2) IP addresses 2: 10.1.132.33 Are there any similarities?
The three groups are same, all are 10.1.132, last group is not same. What is similar about the IP addresses?
The three groups are same, all are 10.1.132, last group is not same. What is similar about the default gateways? The default gateways are same ip address. The IP addresses should share the same network portion. All machines in the LAN should share the same default gateway.
Check additional TCP/IP configuration information
To see detailed information, type ipconfig /all and press Enter. The figure shows the detailed IP configuration screen.
The host name, including the computer name and NetBIOS name should be displayed. Also, the DHCP server address, if used, and the date the IP lease starts and ends should be displayed. Look over the information. Entries for the DNS, used in name resolution servers, may also be present.
8.Mark the Physical Address (MAC) and the NIC model (Description). MAC: 44-37-E6-D1-EB-2B; NIC: Realtek PCIe GBE Family Controller 9.While not a requirement, most LAN administrators try to standardize components like NICs. Therefore, it would not be surprising to find all machines share the first three Hex pairs in the adapter address. These three pairs identify the manufacturer of the adapter. 44-37-E6
10.Write down the IP addresses of any servers listed (if any): DHCP Server:10.1.132.254; DNS Server:210.32.32.10,210.32.32.11 Write down the computer Host Name: Hdusec-42 Write down the Host Names of a couple other computers:
