MTR combines the functionality of the 'traceroute' and 'ping' programs
in a single network diagnostic tool. The mtr-gtk package provides the
GTK interface for MTR.
When MTR is started, it investigates the network connection between the
host MTR runs on and the user-specified destination host. Afterwards it
determines the address of each network hop between the machines and sends
a sequence of ICMP echo requests to each one to determine the quality of
the link to each machine. While doing this, it prints running statistics
about each machine.
