layer-four traceroute

This sends various TCP SYN and FIN probes (differing from Van Jacobson's UDP-based method) utilizing the IP protocol "time to live" field and attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to some host. lft also listens for various TCP and ICMP messages along the way to assist network managers in ascertaining per-protocol heuristic routing information and can optionally retrieve various information about the networks it traverses.
