It may often encounter such a situation: I may take a long time to connect when accessing a website, or I can't access the needed website. How can we know the quality of the line? Please see several network test commands in this article to master them help to use and maintain the network:
First, ping usage format: ping [x] [-t] [-a] [-n count] [-l size] parameter introduction: -t Let the user constantly send data -a in IP address format To display the network address of the target host - N count specifies how many times to ping, the specific number of times is specified by the rear count to specify the size of the data packet sent to the target host: Used to test a frame data from one host The time required to transfer to another host is used to determine the primary response time. The number is ranked second in the test engine. But even in this way, we still think that Yahoo can be ranked first, it is recommended that everyone browsing or searching people will use it. Detailed introduction: This command is primarily used to check if the route can reach a certain site. Since the length of the command is often small, the speed transmitted online is very fast, and it can quickly detect whether the site you want to go is. If you do not succeed, you can predict that the fault appears in the following aspects: Whether the network cable is connected, whether the network adapter configuration is correct, whether the IP address is available. If the network is still unusable, the network is still unusable, then the problem is likely to be in the software configuration of the network system, and the success of the ping can only guarantee a physical path with a communication between the current host and the destination host. Its usage format is to type: ping IP address or host name at the command prompt, and execute the result shows the response time. Repeat this command, you can find that the response time of the ping report is different. After the specific ping command, you can follow the multi-parameter, you can type the pick to enter the car to get a detailed description. For example: When we want to access a site (such as www.chinayancheng.net), you can use the ping program to test how the current connection is currently connected. At the time of execution, click the "Start" menu and select the "Run" command, enter the URL (for example, ping www.chinayancheng.net) to the User to test in the Run dialog, the program will be directed. The primary server of the web URL sends a 32-byte message, then it records the response time of the server. The PING program will display the four test results to the user. The response time is less than 300 milliseconds can be considered normal, and the time is more than 400 milliseconds. The "Request Time Out" message means that the URL does not respond within 1 second, indicating that the server does not respond to the configuration or the URL response is extremely slow. If you see 4 "Request Pause" information, the URL refuses the PING request. Because too many ping tests themselves generate bottlenecks, many web administrators do not allow the server to accept this test. If the URL is very busy or out of other reasons, if the hardware power is insufficient, the data channel is narrow, you can try again for a while to determine the URL is really faulty. If there is a problem with multiple tests, it can be considered that the user's host and the site are not connected, and the user should contact the Internet service provider or network administrator in time. Second, IPCONFIG uses format: ipconfig [/?] [/ All] parameter introduction: /? Display IPConfig's format and parameters English Description / ALL Displays the main functionality of all configuration information about IP addresses: Display IP protocol inside the host's host Configuration Information Details: The IPConfig program uses the Windows window to display the specific configuration information of the IP protocol. If the ipconfig command does not run directly with any parameters, the program will display the physical address of the network adapter, the IP address, subnet mask, and the default gateway, etc. of the host in the window. You can also view the host's related information by this program, such as: host name, DNS server, node type, etc.
The physical address of the network adapter is very useful when detecting network errors. Type IPConfig /? You can get the use of IPConfig, type IPConfig / ALL to get all properties of the IP configuration. Examples: If we want to quickly understand the specific configuration of a host's IP protocol, you can use the ipconfig command to detect. The specific steps are as follows: First click the "Start" menu, find the "Run" command from the pop-up menu, then the program opens a dialog that titled "Run", in the dialog, we can enter ipconfig Command, then click on the Enter key, we will see an interface as shown on the left. If the user wants to understand other IP protocol configuration information of the host more detail, such as information on the DNS server, DHCP server, etc., you can directly click on the Details button in the interface. Third, Tracert uses format: Tracert [-d] [-h maximum_hops] [-j host_list] [- w timeout] parameter introduction: -d does not resolve the name of the target host - H maximum_hops Specify the maximum number of hops search to the target address - J Host_List Follow the address release source routing in the host list to specify timeout time intervals, the default time unit of the program is the main function of milliseconds: determine the path passed by the packet to the host, display the number of relay nodes passed by the data package and Time of arrival. Detailed introduction: This application is primarily used to display the path to the host to the host. The usage format of this command is to type the following command at the DOS command prompt or in the Run dialog: Tracert host IP address or host name. The execution result returns the list of interrupt stations experienced by the destination host and displays the time of each relay station. This feature is similar to the ping command, but what it sees is much more detailed than the ping command, it will give you the request package you sent to a certain site, and all the routings you tell you, and tell you through the route What is IP, how much is the time of this IP. After the specific tracert command, you can also follow the multi-parameter. You can type tracert and return to the car, which will have a detailed description. For example: If you want to know more about the transfer path information between your computer and the target host, you can use the Tracert command to detect it. The specific steps are as follows: First click the "Start" menu button, find the "Run" command from the pop-up menu, then the program opens a dialog that titled "Run", in the dialog, enter Tracert WWW .ch Chinacheng.net command, click Enter key, we will see an interface as shown on the right. Of course, everyone can also enter the tracert www.chinayancheng.net command in the MS-DOS mode, and also see the result screens shown on the right. In this picture, we can track the path information connected to the target website www.chinayancheng.net, such as how many times in the middle, spend more time after a transfer station is taken. Through these times, we can easily find out where the user between the user's host and the target website is out. If we add some parameters after the Tracert command, we can also detect more more detailed information. For example, using parameter -D, you can specify the program of the program host when the program is tracked, and also parses the domain name of the target host.
Fourth, NetStat uses format: NetStat [-r] [-s] [-n] [-a] parameter introduction: -r Displays the contents of this machine routing mark-S display each protocol (including TCP protocol, UDP protocol , IP protocol) -N Display address and port -a in digital table Shows the main function of all hosts: This command allows users to understand how their host is connected to the Internet. Detailed introduction: The NetStat program helps us understand the overall use of the network. It can display details of the currently active network connection, such as displaying network connections, routing tables, and network interface information, allowing users to know what the current network connection is running. Can we use NetStat /? Command to see the usage format of this command and detailed parameter description. The usage format of this command is to type the following command in the DOS command prompt or directly in the Run dialog box: NetStat [parameter], using the parameter function provided by the program, we can understand other function information of the command, such as display The statistics of the Ethernet show the use of all protocols, including TCP protocols, UDP protocols, and IP protocols. You can also select a specific protocol and view its specific usage information, and display all host port numbers and the detailed routing information of the current host. For example: If you want to know the export address of the salt city information network center node, a gateway address, machine address, etc., you can use the netstat command to query. The specific method is as follows: First click the "Start" menu button, find the "Run" command from the pop-up menu, then the program opens a dialog that is titled "Run", in the dialog box, enter the netstat command directly, Click Enter key, we will see an interface as shown on the left. Of course, you can also enter the netstat command in MS-DOS mode. In the IP interface, we can understand the type type used by the user host, the current host and the remote network IP address and the connection status between the connection status and other information related resources: common network test commands use detailed explanation
