The world can no longer imagine life without the Internet. Millions of people are sitting on social networks, playing online games, looking for information in search engines, making purchases and paying for certain services. And if only a few years ago, the speed and quality of the Internet was rarely discussed, now with a huge choice of providers these two qualities of Internet services come to the fore. Therefore, energy and effort has been spent on the diagnosis and debugging of computer networks, and this is not an easy task.
Often there are problems with the lack of communication of some users or even a whole group of machines. What to do then? And how to determine the quality and availability of individual nodes and network segments to the administrator?
In many ways, the Ping team will be able to clarify the situation, which can be used in almost any operating system. Let's try to figure out what kind of team it is and in what cases it is used.
The Ping command determines the exact response time of the remote server to which ICMP packets are sent. It is used by network administrators to diagnose the availability problem of individual segments or nodes. But this does not mean that an ordinary user cannot use it.
The Ping team is a universal tool available to everyone and at any given time. In addition, the syntax of its use is so simple that even a person who did not deal with computer networks at all will like it. It includes a wide arsenal of parameters, with the help of which it is possible to put more precise operation parameters in front of the system. On operating systems, the Ping command (Windows, Unix) is quite simple. To do this, just run it in the appropriate application.
For example, for Windows users, it is enough to run the
command line and enter the following text: ping <host name or its IP address>, where the triangular brackets indicate the node for which you are going to check ping. For users of Unix-systems, all the above steps are enough to execute in the terminal.
The Ping command is most often used with the -t, -s, -i options . The first allows you to track the action of the command an unlimited number of times (that is, ping does not complete its work after the time allotted by the standard settings). The second is to change the size of the ICMP packet that is sent to some computer or server, and the third is to change the interval between sending these packets. You can also use other parameters that you can learn about by calling the local help for this command.
It is quite logical that a simple user may have a question: “How to interpret the results of a team?”. Answering it, it is worth noting that ping gives a general idea of the speed of moving a packet over an existing network. If it passes between nodes with a certain interval, without frequent jumps, then this is evidence of correct operation, but if packets arrive with a strong delay or do not reach at all, this means that there are some problems on the network that urgently need to be solved by the computer administrator system.
