| + | ===== Capturing an MTR ===== | ||
| + | In some cases, you may be asked by support to provide an MTR to diagnose potential routing issues between your service and another point on the internet. Below are 2 methods on capturing an MTR, one for Windows and one for each flavour of Linux. | ||
| + | ==== Windows (WinMTR) ==== | ||
| + | * Download [[https:// | ||
| + | * Extract the contents of the .zip file to your desktop. | ||
| + | * Open the WinMTR folder, then open the folder that matches your version of Windows (32-bit or 64-bit) and run WinMTR.exe. | ||
| + | * Enter the IP address you want to test in the Host field. This will be the IP of the service you're diagnosing. | ||
| + | * Note: If multiple IPs are listed, run a WinMTR test for each IP address. | ||
| + | * Click Start, then launch the server you're testing. If no connection issue is found in the first 5 minutes, restart the test. | ||
| + | * When a connection error occurs, play for at least 5 more minutes, then click Stop in WinMTR. | ||
