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.\\ \\
