In daily life, all we often say the word "route": automobile roads, cable route.The term is also used by designers when working with graphics, programmers when debugging applications, administrators of computer networks and so forth. Such a wide distribution does not allow for a clear definition of - depending on the application has its own characteristics, is separately specified.In general, the route is a direction, or, if you prefer, conditional line.
In today's article we will focus on networking: how to make the trace.But first, let's see who it might be useful to this material.If the server administrator all understandable, because it is their direct work, how is associated with tracing an ordinary computer user?Familiar to many situations: one (or not) point favorite site on the WAN is no longer open.The problem with the connection?Maybe the target server being any work?Or a local caching proxy somehow incorrectly processes the request?It is understandable that everyone wants to know the real reason for what is happening, but not at random to check their guesses.For this are two software tools that enable the site and check the ping to trace.
Any site - a collection of text pages (meta-language), which are located on the server.This is a special computer (host) connected to the network clock.When the user in the address bar of your browser enters the name of the site to the server request is sent to the carrier, and returns a response (the site is displayed).However, it is rarely a user's computer is directly connected to the communication lines to that server.Typically, there are between other nodes - proxies partially "transparent" for the query.Tracing to the server provides a kind of map - the route by which the signal passes.Closely watching it you can with high probability indicate the reason for inoperability resource.
Knowing how to make a trace, you can immediately "cut off" the communication cable fault or browser settings.Also, problems are easily identified by the ISP.To understand how to make tracing, quite simply, because the necessary software is included in all major operating systems (Vindous, Linux, Mac OS).In the first case it is called "tracert", and the second - "traceroute".This is the main difference, so using the tool in different systems is identical.
imagine that the system does not open the site Vindous fb.ru, with all other web resources available.How to trace?Pressing a combination of "Win + R", run the command line.In line typed "tracert fb.ru" and execute (Enter).A window appears with the current results.They are always different.It depends on the workload of the hub and the selected protocol route data packets.
When the syntax will be given the total number of intermediate servers, their IP-addresses and ping value on each of them.Oversized Ping means delays when opening the target site, but the message exceeds timeout indicates the obvious problems on this route (highway).By the way, their presence does not mean that the site can not be opened, as the node may be only a temporary problem.In fact, the tool tracert gives an indicative, though their reliability is quite high.If a delay occurs in the intermediate nodes, it is necessary to repeat the request after the time - change the way and the site will open.But if the delay on the target server, the cause of malfunction is obvious - it is any problem on the side of the hosting provider.
