Conforme la red de sistemas se va complejizando e interconectando son necesarias herramientas simples que nos permitan verificar o comprobar la calidad de dichas conexiones, lo cual puede ser extrapolable a los servidores VPS Perú. Asimismo, es indispensable poder detectar errores en el menor tiempo posible para que interconexión de los sistemas se mantenga, tanto en redes domésticas como en VPS Perú. En ese aspecto, interviene tracert o tracerroute.
Tracert o traceroute es una herramienta que permite diagnosticar el fallo de las conexiones de redes o conexiones a Internet domésticas o VPS Perú. Así, por ejemplo, si tienes dificultades para acceder a un sitio web, puede diagnosticar si el problema es tuyo, de la web o de algún punto intermedio en la conexión, lo cual resulta importante en el análisis del funcionamiento de tu IP VPS Perú, por ejemplo.
What is Tracert or Traceroute?
Tracert is a Windows application, while traceroute is the name of the same function for GNU/Linux, UNIX, and Mac operating systems. Therefore, it is known as tracert or traceroute. This application runs directly in the command consoles of operating systems. It is used in the console with the command called tracert.
Its function is to review the route that an incoming data packet takes from a host or network point to the user's device. This function examines each node or router traversed and the response time of each one. In this way, it performs a diagnosis of the network's functionality, obtaining statistics on RTT or network latency.
Additionally, it provides the IP addresses of the nodes traversed. This creates a map of the connections to detect failure points. Thus, it is widely used in local networks with many connected devices.
Asimismo, cabe destacar que esta herramienta puede ser aplicable al análisis del IP VPS Perú. Esto resulta útil, sobre todo, en el caso de contra con un servicio de VPS Perú no administrado que requiera de la gestión personal. No obstante, es indipensable que el usuario VPS Perú compruebe que la política de seguridad del proveedor VPS Perú permita el uso de este comando.
How Does Tracert or Traceroute Work?
This command works by sending ICMP packets, which are a protocol for Internet Control Message Protocol. This protocol is used to send operational information messages or error messages in data transmission between the device and the Internet, considering the nodes through which this data passes.
The tracert command uses the Time to Live (TTL) field to determine how many nodes a data packet traverses. The integer value TTL is part of the IP header and decreases as each node is traversed until it reaches a value of 0. Thus, this TTL acts as a hop counter, that is, for each router or node that the packet traverses.
A message with a TTL value that expires at each node is sent, so that each of these nodes returns a message informing about its IP, its connection time, latency, and whether an error is recorded. This allows detecting where the connection problem occurs.
However, it is essential to highlight that for the tracert or traceroute command to be used, we need to have a command line or prompt open. This works differently depending on the operating system.
Due to the information obtained from the nodes, it is possible to evaluate their stability, errors, and latency. This way, not only are errors in the network diagnosed, but also other issues such as latency, that is, how well it is functioning.
How to Interpret Tracert or Traceroute Messages?
After executing the command, the result appears on the first line. It will show the IP of your address and the number of hops or nodes traversed by the information.
The first column will show the number of hops. The tracert or traceroute counts the number of hops and the time it takes to reach its destination.
The second, third, and fourth columns indicate the times, in milliseconds, for the return of each packet sent by the tracert or traceroute. If any of them shows an asterisk, this indicates the presence of a firewall blocking the procedure.
Finally, the fifth column indicates the IP addresses and names of the devices, for example, computer.server.domain.com.
Another alternative when executing the tracert or traceroute command is to receive the message "Request timed out," which would indicate the presence of a blockage in the analysis due to a firewall.
Limitations of Tracert or Traceroute
Despite the great utility of tracert or traceroute, we can identify some limitations in its use. One of the main limitations is the presence of firewalls in the path of the packets, which will block the route check. Therefore, at times, a response may only be obtained up to a certain node.
When this happens, the response from the node will only be an asterisk. The solution to a firewall blockage is to change ports to continue route checks or try a different transport protocol.
Also, some firewalls will block all incoming and outgoing traffic, so the network diagnosis via tracert or traceroute may not be performed properly.
Además, como se ha mencionado anteriormente, la existencia de políticas de seguridad específicas en los servidores VPS Perú, puede bloquear el uso del comando tracert, especialmente, en los VPS Perú no administrados. De igual forma, es indispensable considerar la configuración de firewalls en el servidor VPS Perú antes de ejecutar tracert o traceroute en VPS Perú no administrado.
Alternatives to Tracert or Traceroute
Due to the limitations presented by this function, there are programs that perform the same operation. One of them is Visual Route in Java, which is used to obtain graphical information about the route that data packets take. It uses the information generated by the tracert command in conjunction with the data obtained from the RIPE database for each of these nodes.
Additionally, we can find traceroute servers on the Internet. They are called Looking Glass servers and operate in ISPs with networks that allow these operations to be performed.
Moreover, there are servers that enable the visualization of the traceroute result from the host to any other point, allowing the generation of maps of the data packets' journey.
Como se puede ver, las utilidades tracert o traceroute son muy variadas. Esta herramienta ns permite no solo la solución de problemas, sino, también, el monitoreo del adecuado funcionamiento de los sistemas en los que operamos y la conectividad de nuestras redes domésticas o empresariales. En adicion, es un comando de uso frecuente que es recomendado al tener problemas de acceso a tu servidor VPS Perú, debido a inconvenientes de conexión a Internet o de acceso a tu cuenta VPS Perú, de modo que puede resultar en ser un sistema de verificación y análisis conveniente, sobre todo, en relación a la gestión del VPS Perú no administrado.
