![]() If you have a way to login to a remote computer, you can also check the reverse connection to the IP address of your home network. Replace with the internet host name you would like to check: mtr -rw Generate MTR reports using the following syntax: mtr -rw įor example, to test the route and connection quality of traffic to the destination host : mtr -rw Īn MTR report can be run from your local computer. When referring to MTR reports, this document refers to the host running mtr as the source host and the host targeted by the query as the destination host. This is because, from time to time, MTR reports will not detect errors from one direction when there is still packet loss from the opposite direction. For this reason it is a good idea to collect MTR reports in both directions for all hosts that are experiencing connectivity issues.Ĭustomer Support will often request MTR reports both to and from your host if you are experiencing networking issues. The route taken between two points on the Internet can vary a great deal based on location and the routers that are located upstream. To install MTR with MacPorts, run: port install mtrīecause MTR provides an image of the route traffic takes from one host to another, it is essentially a directional tool. To install MTR with Homebrew, run: brew install mtr Install MTR on macOS with either Homebrew or MacPorts. You can download this application from the WinMTR upstream. Install MTR Linuxįor Windows there is a port of MTR called "WinMTR". The following sections outline how to install the MTR software and how to interpret the results provided by this tool. Because of this additional information, MTR can provide a complete overview of the connection between two hosts on the Internet. Rather than provide a simple outline of the route that traffic takes across the Internet, MTR collects additional information regarding the state, connection, and responsiveness of the intermediate hosts. By sending a series of packets and causing them to return after one hop, then two, then three, MTR is able to assemble the route that traffic takes between hosts on the Internet. The TTL, or time to live, controls how many hops a packet will make before "dying" and returning to the host. In contrast, tools such as traceroute and MTR send ICMP packets with incrementally increasing TTLs in order to view the route or series of hops that the packet makes between the origin and its destination. The user's client is then able to compute the round trip time between two points on the Internet. ![]() When a user pings a host on the Internet, a series of ICMP packets are sent to the host, which responds by sending packets in return. Networking diagnostic tools including ping, traceroute, and mtr use Internet Control Message Protocol (ICMP) packets to test contention and traffic between two points on the Internet. Network Diagnostics Backgroundįor a simple overview, check this document about network diagnostics. ![]() If you are having general issues with your system, read our overview of general system diagnostics. This document provides an in depth overview of MTR, the data it generates, and how to interpret and draw conclusions based on the data provided by it.įor a basic overview of network diagnostic techniques, see our introduction to network diagnostics. MTR represents an evolution of the traceroute command by providing a greater data sample, as if augmenting traceroute with ping output. MTR is a powerful tool which enables administrators to diagnose and isolate networking errors and provide reports of network status to upstream providers. ![]()
