Matt's Traceroute Feature

The Matt's Traceroute feature is for analyzing the current network status. For more details, please refer to the link provided.

The MTR feature is provided as a real-time updated Terminal UI (TUI) and supports detailed route diagnosis and measurement result report transmission.

To use this feature, you must enable Expert Mode for it to appear in the advanced features menu.

Examples​

Example: 208.95.186.196​

For example, if you want to proceed with a test targeting the IP 208.95.186.196, you can execute it as follows.

  1. Turn on the Mudfish Launcher and log in. After enabling Expert Mode, visit the "Advanced -> Matt's Traceroute" menu.

  2. Enter 208.95.186.196 on the screen and start.

Example: Mudfish Relay Server Target​

You can execute it as in the Example: 208.95.186.196 section above, but you need to change the IP to the public IP of the Mudfish relay server.

The public IP of the Mudfish relay server can be checked at the link https://mudfish.net/server/status.

Screen Controls and Features (TUI)​

When the test starts, you can check the real-time updated hop-by-hop statistics on the screen, and you can control various features with the shortcut keys below.

  • Tab: Open runtime settings screen (can change probe interval, max hops, total cycles, reverse DNS lookup, etc.)
  • s: Send report (sends the measurement results so far to the Mudfish server for issue analysis)
  • r: Restart measurement
  • q or Esc: Quit / Return to the previous screen

Understanding the Results​

While the test is in progress, you can continuously observe the results for the destination. The explanation for each item currently displayed is as follows:

  • # (Hop)

    Indicates how far the router is currently from your computer. If you are using a router, Hop 0 or 1 usually represents your router.

  • Host (Address)

    Indicates the IP address or hostname of the discovered router.

  • Loss% (Packet Loss)

    Indicates the packet loss rate that occurred reaching the corresponding Hop. If the packet loss for that Hop is 100%, it can be ignored. Usually, this happens when the router corresponding to that Hop does not send ICMP packets.

    However, if the packet loss is 1 ~ 99%, it can be a meaningful result value.

  • Sent / Recv (Requests / Responses)

    Indicates how much testing has been done. (Sent: Transmission count, Recv: Response count)

  • Best / Avg / Wrst / Last / StDev (RTT Statistics)

    Shows the results of the RTT (Round Trip Time) test for each hop.

    • Best: Minimum latency
    • Avg: Average latency
    • Wrst: Maximum (worst) latency
    • Last: Most recent latency
    • StDev: Standard deviation of latency

Based on the information above, you can check how many hops exist to the destination and how stable the connection is or the packet loss rate. For reference, these results are measured via the ICMP protocol.
