Every computer user has encountered a problem such as a network problem. In this case, everyone immediately starts the network diagnostic program so that it independently finds the problem and fixes it. However, this is not the only way to deal with the problem. Now we’ll talk about the most ordinary and simple though, at first glance, this may seem completely different, but initially we need to figure it out.
This article will focus on the command line, or rather on the commands that will help troubleshoot network problems. All, of course, will not be listed, but we will touch on the main ones, such as ipconfig all, ping and tracert. Well, now about everything in order.
How to display the command line
As mentioned above, to enter the ipconfig all command, a utility such as the Windows command line is required. On other operating systems, such as UNIX-like, this command is also present, but more on that later.
In order to open the command line, you can use different ways. Everything will be listed so that everyone finds it to their liking.
The most common algorithm for an avid Windows user to open a command line will be through the Start menu. To do this, go to this menu and go to the "All Programs" section. There, turning the mouse wheel down, look for a folder called "Standard" and already in it find the very command line utility.
The second method is much faster than the first, but perhaps people far from the computer will not understand it. But still, open the Start menu and find the Run line in the sidebar. After clicking, a window will appear in the lower left corner of the desktop. In the input field write “cmd.exe” and click “OK”.
If for some reason you did not find “Run,” then the third method is especially for you. Instead of unsuccessful searches, just press the Win + R hotkey combination and the treasured window will appear. Well, then you know what to do, enter “cmd.exe” in the line and click “OK”.
The command line is open, which means that you can begin to consider the ipconfig all, ping, and tracert commands.
IPConfig
The first in line and in importance will be the ipconfig command. If you often encounter problems with the network, then you should know this command from A to Z, as it will help you find the causes of the problems, analyze them and prevent them.
By entering this command, you will see all the information about the IP address of the PC, and also DHCP, DNS, gateway and subnet mask will be affected. Of course, you can ask a reasonable question, but what to do next with this information? Yes, after entering ipconfig or ipconfig all, the problems themselves will not be fixed. However, you can understand exactly what the problem is.
For example, if the screen shows that you have a gateway of 0.0.0.0, then know that the problem is with the router.
Ping
Ping is the second most important team that is used to solve network problems. It is entered in the case when it is necessary to check all the connections between the node itself and its purpose. Thus, it is possible to find the area that causes problems.
By typing this command and pressing Enter, you will see the status of the router. A connection check will also be conducted four times with a detailed description. In the event that there will be no answers to requests, then be aware - there are problems in the network card.
Tracert
Tracert is another important team. Without her, this article would be incomplete. Now consider it in more detail.
This command is used to track absolutely the entire path of the data you send. This command displays on the monitor a list of all the transit points to which the data falls before they reach the required place. After analyzing the information received, you can find out at what stage your signal breaks, and understand what to do next. Typically, items in which a malfunction occurs are indicated by a “*”.
That, in principle, was all I wanted to tell. As stated at the very beginning, the ipconfig command is also present on UNIX-like systems such as Linux. However, the string will need to be entered not ipconfig, but ifconfig. Of course, the interface itself will also differ from Vindovsky, but the fact is a fact - Linux supports the ipconfig command.
