Nmap Development: Re: nmap (win32 4.60) bug and a fix

Re: nmap (win32 4.60) bug and a fix

Hi all,

I tried to reproduce the problem to no avail on an up-to-date WindeXP!
Without any option, this is what I get :

[snap]
C:\Program Files\Nmap>nmap 192.168.51.255

Starting Nmap 4.60 ( http://insecure.org ) at 2008-04-09 11:11 Est (heure
d'ÚtÚ)

Note: Host seems down. If it is really up, but blocking our ping probes, try
-PN

Nmap done: 1 IP address (0 hosts up) scanned in 0.610 seconds
[/snap]

Problem is the IP address - 192.168.51.255 - could be a valid unicast, it
all depends on the subnet mask...

Dudi, could you be more specific about the Win32 version and maybe the
command you try to pass ? I just want to make sure the problem is specific
to Nmap and not the host itself...

Tankiou,

Ion
