1. Full screen ncurses and X11 traceroute tool 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. From Debian 3.0r0 APT

2. Mtr is a network diagnostic tool that combines ping and traceroute into one program. Mtr provides two interfaces: an ncurses interface, useful for using Mtr from a telnet session; and a GTK+ interface for X (provided in the mtr-gtk package). From Redhat 8.0 RPM
