The world can no longer imagine life without the Internet.Millions of people sit in social networks, play online games, search for information in search engines, make purchases and pay for certain services. And if several years ago the speed and quality of the Internet did not often come up, now with a huge choice of providers these two qualities of Internet services come to the fore. Therefore, energy and forces are spent on diagnosing and debugging the work of computer networks, and this is not an easy task at all.
There are often problems with the lack of communicationsome users or even a whole group of machines. What to do then? And how to define the administrator the quality and availability of individual nodes and network segments?
The Ping command determines the exact response timethe remote server to which ICMP packets are sent. Applied by its network administrators to diagnose the problem of accessibility of individual segments or nodes. But this does not mean that an ordinary user can not apply it.
The Ping command is a universal tool availablefor all and at any time. In addition, the syntax of its use is so simple that even a person who does not have to deal with computer networks will like it. It includes a wide arsenal of parameters, through which you can put in front of the system more precise parameters of work. In operating systems, the Ping (Windows, Unix) command is quite simple. To do this, just run it in the appropriate application.
The Ping command is most commonly used withparameters -t, -s, -i. The first allows you to track the action of the command an unlimited number of times (that is, ping does not finish its work after the time set 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, which you can learn about by calling the local help for this command.
It is quite logical that a simple user canthe question arises: "And how to interpret the results of the action of the 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 at a certain interval, without frequent jumps, then this is the evidence of the correctness of the work, but if the packets come with a strong delay or do not reach at all, this means that the network has some problems that need to be urgently addressed to the computer administrator system.
