Although it is very similar, WinMTR shares no common code with MTR.Ī console version of MTR does exist for Windows, but it has fewer features than MTR on other platforms. ![]() It was originally developed by Appnor MSP S.R.L. WinMTR is a Windows GUI application functionally equivalent to MTR. Keys: Help Display mode Restart statistics Order of fields quitġ. MPLS labels are displayed by default when the "-e" switch is used on the command line (or the "e" key is pressed in the curses interface):ĭax.

This example shows MTR running on Linux tracing a route from the host machine (example.lan) to a web server at Yahoo! (p25.across the Level 3 Communications network. This can help identify network overuse problems. By showing a list of routers traversed, and the average round-trip time as well as packet loss to each router, it allows users to identify links between two given routers responsible for certain fractions of the overall latency or packet loss through the network. The tool is often used for network troubleshooting. MTR also supports IPv6 and works in a similar manner but instead relies on ICMPv6 messages. ![]() When the UDP mode is used, MTR relies on ICMP port unreachable packets (type 3, code 3) when the destination is reached. Enter a target computer or domain name, optionally choose a trace interval (15 options ranging from 1 second to 60 minutes), click Start and you’re off. MTR also has a User Datagram Protocol (UDP) mode (invoked with "-u" on the command line or pressing the "u" key in the curses interface) that sends UDP packets, with the time to live (TTL) field in the IP header increasing by one for each probe sent, toward the destination host. Just like the name says, PingPlotter plots ping (and traceroute) data on a graph over a period of time. MTR relies on Internet Control Message Protocol (ICMP) Time Exceeded (type 11, code 0) packets coming back from routers, or ICMP Echo Reply packets when the packets have hit their destination host. It normally works under the text console, but it also has an optional GTK+-based graphical user interface (GUI). MTR is licensed under the terms of the GNU General Public License (GPL) and works under modern Unix-like operating systems. Roger Wolff took over maintaining MTR (renamed My traceroute) in October 1998. ![]() The original Matt's traceroute program was written by Matt Kimball in 1997.
