Layer Four Traceroute - 3.1

This is the best total replacement for traceroute I've found. There are other options, notably tcptraceroute, but LFT doesn't make you choose between tracing protocols.. You can use TCP or UDP. You can manipulate protocol state and set every knob and lever you'd ever want. Plus, it's the only one available with integration of whois sources for routing information instead of just integrating registrar lookups. If you're looking for a flexible traceroute replacement that does it all, look no further. I've used this for years and it keeps getting better.

I also noticed the author has a graphical version for Windows and Mac OS X called Path Analyzer Pro. I haven't checked it out yet, but I will.

Use the Developer's Site link above and then look for "LFT MacOS X" under the Download LFT section on the right.

You'd think that the pre-built version should be what's listed for this package on VersionTracker, not (just) the source kit.

It *is* just a command-line utility -- not a GUI so if you're not comfortable with Terminal you won't benefit from this package at all.

I put a copy of pcap-int.h onto my system and still could not build this utility:

% make
gcc -g -O2 -c -o lft.o lft.c

This was after a ./configure without any additional parameters. If we need to supply some for the make to then succeed on Mac OS X (10.3.7 in my case) it wasn't immediately apparent in the INSTALL document.

Oh well, it sounded like a cool tool.

Missing pcap-init.h header file keeps v2.31 from compiling:

lft.c:85:22: pcap-int.h: No such file or directory

v2.3 compiles fine.

Thanks for the effort. Works but as any CLI, but as <b>all</b> CLI's go, butter (inter)face is damn ugly. Would rather pay for one with a clean interface (like NetBarrier's interface) than use free CLI stuff. Don't mean to disparage effort ... using your tool and appreciative of your work as this functionality is essential to my endeavors... but will throw money at the first clean version which is not done in or relies directly on darwin.
