Every computer user has encounteredsuch a problem as a network problem. In this case, all immediately start the network diagnostics program so that it independently finds the problem and eliminates it. However, this is not the only way to deal with the problem. Now we will talk about the most ordinary and simple, although, at first glance, it may seem quite different, but it is necessary to understand everything from the beginning.
This article is about the command line, or rather- about the commands that will help to troubleshoot the network. All, of course, will not be listed, but we will cover the main ones, such as ipconfig all, ping and tracert. Well, now about everything in order.
As mentioned above, to enter the ipconfig commandAll you need is a utility like the command line on Windows. On other operating systems, such as UNIX-like, this command is also present, but more on this later.
In order to open the command line, you can use different methods. All will be listed absolutely, that everyone found to himself to taste.
The most common for an avid Windows userthe algorithm for opening the command line will be through the Start menu. To do this, go to this menu and follow the "All Programs" section. There, turning the mouse wheel down, find a folder called "Standard" and already in it, find the very utility "Command line".
The second way is much faster than the first, but,perhaps, people far from the computer will not understand it. But still open the "Start" menu and on the sidebar find the "Run" line. After clicking, a window appears in the lower left corner of the desktop. In the entry box, type "cmd.exe" and click "OK."
If for some reason you did not find"Run", then the third way is specially for you. Instead of unsuccessful searches, just press the combination of Win + R hot keys and the treasured window will appear. Well, and then you know what to do, type "cmd.exe" in the line and click "OK".
The command line is open, which means that you can start looking at the ipconfig all, ping, and tracert commands.
The first in line and in importance will be the teamipconfig. If you often encounter problems with the network, then this command you should know from A to Z, since it will help you find the causes of the problems, analyze them and prevent them.
By entering this command, the wholeinformation about the IP address of the PC, and will also affect DHCP, DNS, gateway and subnet mask. Of course, you can ask a reasonable question, but what to do with this information further? Yes, after entering the ipconfig command or ipconfig all the problems will not be fixed by themselves. However, you can understand what the problem is.
For example, if the screen shows that the gateway you have is 0.0.0.0, then know that there is a problem with the router.
Ping is the second most important team thatIt is used to solve problems with the network. 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 that site which causes problems.
By typing this command and pressing Enter, you will seestatus of the router. Another test will be carried out four times with a detailed description. In the event that there are no replies to the requests, then you should know that there is a problem with the network card.
Tracert is another important team. Without it, this article would be incomplete. Now consider it in more detail.
This command is used toto trace absolutely all the path of the data you send. This command displays on the monitor a list of all the transit points, which get the data before they get to the desired location. After analyzing the information received, you will be able to find out at what stage your signal terminates, and understand what to do next. Usually the points at which the problem occurred are indicated by the symbol "*".
Here, in principle, and all that I wanted to tell.As mentioned at the outset, the ipconfig command is also present on UNIX-like systems, such as Linux. However, in the line you will need to enter not ipconfig, but ifconfig. Of course, the interface itself will also differ from "Windows", but the fact is - the ipconfig Linux command supports.
