2.19.3.2. tracert/traceroute

Asterisks instead of values next to intermediate nodes do not always mean that those nodes are unreachable or faulty. Usually, it is simply a configuration on the node that prevents it from sending ICMP response messages. If the request has reached the endpoint safely in a reasonable amount of time, there is nothing to worry about.

tracert/traceroute is a standard utility that can be used to check the status of intermediate nodes on the network route to a site and to determine the network section that is malfunctioning if the site is unavailable. Depending on the operating system used, it uses ICMP or UDP protocol.

Windows

  1. Open command prompt.
  2. Execute the command (instead of example.com, specify the address of the desired site without http:// or https:// at the beginning and / at the end):
    tracert example.com

  3. Wait for the results of execution:

macOS

  1. Open terminal.
  2. Execute the command (instead of example.com, specify the address of the desired site without http:// or https:// at the beginning and / at the end):
    traceroute -I example.com

  3. Wait for the results of execution.

    В вашій команді помилка: між - та I стоїть пробіл.
