The version of traceroute on Zerkalo.harvard.edu is a composite of the various available sources and enhancements (including source-route ability). IF THE VERSION OF TRACEROUTE ON ZERKALO IS NOT THE MOST COMPLETE, I WOULD APPRECIATE IT IF SOMEONE WOULD SET US STRAIGHT. THANKS!! Also, some machines' operating systems no longer require kernel modification to support traceroute. Happy debugging, Bob Enger

As far as I know, the traceroute package on zerkalo and the 4.3
bsd-reno traceroute on (e.g.) wuarchive.wustl.edu are the latest of
the publically available traceroute implementations for BSD Unix.
There is no way to know what all else other people might have hacked
into the code, in their own effort to make it complete. If someone has
done this they haven't spoken up.
By the way, how's the "noctool2" group's efforts coming along? Send
me some mail (if you can read my mangled address), I have some
contributions to make.

It is also available on ftp.cc.berkeley.edu, along with my two trivial hacks: 1) The -n option now works. 2) It attempts to detect assymetric routes (the Open Jaw routing problem). It does this by examining the TTL in the ICMP Time Exceeded messages returned by each hop. It turns out that this method is flawed because there are at least 6 commonly used initial values for TTL in ICMP messages (29, 30, 59, 60, 255, and TTL_in_packet_received). So far I have found this second feature useful exactly once. Other times it has been interesting, but nothing more. Cliff Frost UC Berkeley
