Nmap 3.93: Spoof mac does not work when network card not in promiscious mode

[Greg Darke <starstuff () optusnet com au>]

Hi list,

I have just been playing around with the version 3.93 of Nmap, and
discovered that when you run a scan with the '--spoof_mac 0' option, it
is only able to scan itself. Then when I started up ethereal to see what
was (or wasn't) happening, Nmap started to see all of the remote hosts
and correctly scanning them.

This could also be the reason why the arp scan with spoof mac enabled
doesn't work correctly.

I am running Linux (Fedora Core 4). My kernel version is 2.6.12-1.1390,
I am using a Marvell 88E8036 Fast Ethernet Controller (using the sk98lin
driver).

Greg
