MTR was written by Matt Kimball, with contributions by many people. Take a look at the “AUTHORS” file in the distribution. Roger Wolff took over maintenance of MTR in october 1998.
MTR combines the functionality of the ‘traceroute’ and ‘ping’ programs in a single network diagnostic tool.
As MTR starts, it investigates the network connection between the host MTR runs on and a user-specified destination host. After it determines the address of each network hop between the machines, it sends a sequence ICMP ECHO requests to each one to determine the quality of the link to each machine. As it does this, it prints running statistics about each machine.
