[English] Debian Almquist Shell (dash) mtr Usage: Network diagnostic tool

Overview

The mtr command combines the functionality of the traceroute and ping commands to provide a comprehensive view of the network path to a destination. It helps diagnose network issues by showing the route packets take to reach a specific host, along with the latency and packet loss at each hop.

Usage

The basic syntax of the mtr command is as follows:

mtr [options] [destination]

Common Options

• -r: Run in report mode, providing a summary of the results.
• -c <count>: Specify the number of pings to send.
• -i <interval>: Set the interval between pings in seconds.
• -w: Use wide output format for better readability.
• -p: Show the port number in the output.

Common Examples

Here are some practical examples of using the mtr command:

1. Basic usage to trace a route:

   mtr example.com
   

2. Run in report mode with a specified number of pings:

   mtr -r -c 10 example.com
   

3. Set a custom interval between pings:

   mtr -i 2 example.com
   

4. Use wide output format for better readability:

   mtr -w example.com
   

5. Show the port number in the output:

   mtr -p example.com
   

Tips

• Use mtr with the -r option for a quick summary if you want to avoid continuous output.
• Combine the -c option with -r to limit the number of pings and get a concise report.
• If diagnosing intermittent issues, consider increasing the interval with the -i option to reduce network load.
• Regularly check the results of mtr to identify any persistent latency or packet loss issues in your network.
