result:

(3) Enter pathping -n www.baidu.com and press Enter to view the analysis results.

result:

4. Test the pathping command using different parameters.

4. netstat

Netstat is a program in the kernel that accesses the network connection status and related information. It can provide reports on TCP connections, TCP and UDP listening, and process memory management. It is a very useful command for monitoring TCP/IP networks. It can display routing tables, actual network connections, and status information of each network interface device.

1. Click the Start button, type cmd and press Enter to enter the Windows DOS environment.

2. Enter netstat/? and press Enter to learn the basic usage of the netstat command. The result is as follows:

3. Enter the following commands in sequence and press Enter to view the analysis results.

(2) Enter netstat -b and press Enter to view the analysis results.

result:

(3) Enter netstat -a and press Enter to view the analysis results.

result:

(4) Enter netstat -e and press Enter to view the analysis results.

result:

analyze: Display Ethernet statistics. This option can be used in conjunction with the -s option.

4. Test the netstat command using different parameters.

5. Use of arp command

The arp command displays and modifies the Internet to Ethernet address translation table. This table is usually maintained by the Address Resolution Protocol (ARP). When only a host name is used as an argument, arp displays the current ARP entry for that host. If the host is not in the current ARP table, ARP displays an explanatory message.

1. Click the Start button, type cmd and press Enter to enter the Windows DOS environment.

2. Enter arp/? and press Enter to learn the basic usage of the arp command. The result is as follows:

3. Enter the following commands in sequence and view the analysis results.

(1) Enter arp -a and press Enter to view the analysis results.

result:

(2) Enter arp -s 169.254.112.34 00-cd-0d-33-00-34 and press Enter. Enter arp -a and press Enter to view the analysis results.

result:

(3) Enter arp -d 169.254.112.34 and press Enter, then enter arp -a and press Enter to view the analysis results.

result:

6. Use of nslookup command

The nslookup command is used to query DNS records to check whether the domain name resolution is normal. It is used to diagnose network problems when there is a network failure.

Used to display or set the system's host name.

1. Click the Start button, type cmd and press Enter to enter the Windows DOS environment.

2. Enter nslookup/? and press Enter to learn the basic usage of the nslookup command. Result:

3. Enter the following commands in sequence and view the analysis results.

(1) Enter nslookup www.hbtcm.edu.cn and press Enter to view the analysis results.

result:

(2) Enter nslookup www.baidu.com and press Enter to view the analysis results.

result:

7. Use of net command

NET command is a powerful command line tool. It includes most important management functions such as network environment, services, users, login, etc. It can be used to easily manage the network environment of local or remote computers, as well as the operation and configuration of various service programs. Or perform user management and login management, etc.

1. Click the Start button, type cmd and press Enter to enter the Windows DOS environment.

2. Enter net/? and press Enter to learn the basic usage of the net command. Result:

3. Enter the following commands in sequence and view the analysis results.

(1) Enter net user and press Enter to view the analysis results.

result:

analyze:

(2) Enter net config workstation and press Enter to view the analysis results.

result:

(3) Enter net share and press Enter to view the analysis results.

result:

(4) Enter net share c:\user/delete and press Enter to view the analysis results.

8. Use of route command

The route command is used to display and operate the IP routing table. To achieve communication between two different subnets, a router connecting the two networks or a gateway located in both networks is required.

1. Click the Start button, type cmd and press Enter to enter the Windows DOS environment.
