Hi,

I've just updated the nmap version I use with my students at school in
order to have all prepared for next year (sec. school, we teach them what a
network topology is using zenmap). Since this new version only two hosts
appear in traceroute.

This is the output with 6.25 (zenmap quick traceroute, both Windows and
Linux, also tried with 6.00 from the Ubuntu repo and a compiled 6.25):

This one is the output from a computer with 5.51 installed (using the same

I've been searching the web, looking for the same problem, but have found
nothing. Any help would be appreciated.
