payloads of packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6,
IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring and null
interfaces, and understands BPF filter logic in the same fashion as more
common packet sniffing tools, such as tcpdump and snoop.

MTR
will bring up a curses terminal interface with a constantly updating
report on hops and pings, complete with hostname, best and average
latency, and percentage of packets lost at each link.
