LFT Description

LFT (Layer Four Traceroute) is a sort of traceroute that often works much faster. 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 AS number lookups through several reliable sources, loose source routing, netblock name lookups, and more. LFT project also distinguishes between TCP-based protocols, which make its statistics slightly more realistic, and gives a savvy user the ability to trace protocol routes, not just layer-3 hops.What's New in This Release:· WhoB default behavior was changed due to popular demand.· New configure options were added to perform universal builds and to force gettimeofday calls instead of relying on possibly low-precision packet header times on some platforms.· The build process was improved on NetBSD and Darwin/Mac OS X.
