world can not imagine life without the Internet.Millions of people sit in social networks, playing online games, searching for information in search engines, make purchases and pay for certain services.And if a few years ago about the speed and quality of Internet speech came infrequently, but now with the huge selection of providers of these two quality internet services come to the fore.Therefore, the energy and power spent on diagnostics and debug operation of computer networks, and this is not an easy task.
often have problems with the lack of communication of some users, or even an entire group of machines.What to do then?And how do you determine the quality and availability of administrator of individual nodes and network segments?In many ways the team will be able to clarify the situation Ping, which can be used in almost any operating system.Let's try to figure out what kind of a team, and when it is used.
Ping Command determines the exact response time of the remote server on which sends ICMP-packages.Apply it, network administrators to diagnose the problem of availability of certain segments or components.But this does not mean that it can not be used by ordinary users.
Team Ping - a universal remedy that is available to all and at any time.In addition, the syntax of its use is so simple that will satisfy even the person who is not dealt with computer networks.It includes a wide arsenal of options with which you can put in front of a more precise system operation parameters.Operating systems, the command Ping (Windows, Unix) is performed simply.To do this, you just need to run it in the appropriate application.For example, Windows users simply run the command prompt and enter the following text: ping & lt; hostname or ip-address & gt ;, wherein the triangular brackets in the node for which you are going to test ping.For users of Unix-based systems all the above steps sufficient to fulfill the terminal.
Ping command is most often used with options -t, -s, -i.The first allows you to keep track of action commands unlimited number of times (ie ping does not complete its work at the end of the allotted time, the default settings).Second - change the size of ICMP-packet that is sent to some computer or server, well, the third - to change the interval between the sending of packets.You can also use other options, about which can be found by calling the local help for the command.
It is logical that a simple user might ask, "But how to interpret the results of the action team?".Responding to it, it's worth noting that a ping gives an idea of the speed of the package on the existing network.If it passes between nodes at regular intervals, without frequent jumps, it is evidence of the correctness of the work, but if too packages come with a strong delay or no income, it means that the network there are some problems that need to be urgently addressed to the administrator computersystem.
