AW: Informal Nmap 3.96BETA1 release

["Baumgart, Alexander (K-GOT-1)" <alexander.baumgart () volkswagen de>]

Hello,

i also checked if now interface status (up/down) and scaning on specified
interface work correct. Interface status get correct reported for me. If i
only had 1 adapter enable, i didnt get NmapArpCache error. If i had 2
enabled and 1 unplugged, as described by Sina and khana, i also get the
NmapArpCache error again. So i did some further testing.

Problem is there is no default route, so arp scan for 192.168.121.0/24 didnt
work. Unlucky it gives the
"NmapArpCache() can only take IPv4 addresses" error.

I added a defaultroute, like 

     Netzwerkziel    Netzwerkmaske          Gateway   Schnittstelle  Anzahl
          0.0.0.0          0.0.0.0  192.168.120.254  192.168.120.254      1

and get a more accurate errormsg. So could u both Sina Bahram and khanta
check if u set a default route on the plugged device ? My second device
(eth1) isn't a real eth adapter, its a "AVM FRITZ!web PPP over ISDN" so im
not 100% sure if this workarround did it for u.

I have also noticed this same behavior.

In fact, I was just about to report it :).

Take care,
Sina

The new 3.96BETA1 still gives the ""NmapArpCache() can only  take IPv4
addresses."  error is there is another adapter on the Windows Box that is
enabled but unplugged, disabling the adapter causes nmap to work correctly.
