Re: nmap vs vmware [was: Linux vs. Windows results]

["Sandro Poppi" <spoppi () gmx net>]

Hi again,

It seems I don't run into a Linux vs Windows but nmap vs vmware issue ;)

I set up a new linux box and it worked instantly. Only difference now is the other linux is running under vmware.

Anyway I can't explain why this happens. Or is it as simple as "Don't run nmap under vmware"?

Thanks,
Sandro
