RE: Nmap 4.11: False positive ping results

["Mike C (sec)" <check () imjc com>]

Curious - why do you say the bug was already fixed?

Isn't nmap 4.11 a later version than nmap 4.10?

In fact, isn't nmap 4.11 "the latest Nmap on Windows" (excluding the 4.20
Alpha's) - which Vitaly says is broke?

Regards,

Mike

So it means the bug was already fixed so I don't think anybody is
interested unless the latest Nmap on Windows still has the bug. In
that case use "-vvv -d --packet-trace" options and send the output to
us. You don't need to scan all C class network, one IP that should be
"down" and Nmap is reporting it is "up" is enough to debug the
problem, anyway.
