About:
LFT (Layer Four Traceroute) is a sort of "traceroute" that often works much faster than the commonly-used Van Jacobson method and goes through many configurations of packet-filter based firewalls. More importantly, LFT implements numerous other features, including TCP, UDP, or ICMP-based traces, AS number lookups through several reliable sources, loose source routing, netblock name lookups, and more. LFT also distinguishes between layer-4 protocols, which make its statistics slightly more realistic, and gives a savvy user the ability to trace protocol routes, not just layer-3 hops.

[»] Building on FreeBSD
by Black Adder - Sep 29th 2002 11:11:45

There's no easy contact info on the site for contacting anyone regarding FFT.

Software does not buiild out of the box on FreeBSD 4.6 at least.

Change to get it to work is trivial:

In fft.c:
#ifndef BSD
#include "fft_queue.h"
#endif

Just comment out/remove the first and last lines.

These items (below) are now fixed and applied to all
platforms in release 2.0.

> how does this differ from tcptraceroute fft has been around since 1997-8, several years before tcptraceroute was conceived. (see google pages from MIT) But tcptraceroute definitely looks promising :-)
