mtr 0.73-1 (i386 binary) in ubuntu jaunty

 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.
