Nmap Development: RE: nmap sending encapsulated packets

RE: nmap sending encapsulated packets

IIRC running "nmap" from the command line might be a bit misleading, as I
think when I last took a quick look at the zenmap code a while back it
appeared (to my very rusty Python eyes) that it was searching a hardcoded
list of paths (for "nmap"; not "nmap.exe"), rather than honouring (I'm
British :P) the system or user's PATH settings in Windows. You could perhaps
try searching for nmap.* on your system, just to make sure?

I'm surprised that running "nmap -V" in zenmap causes problems, as all nmap
is doing is printing the version and exiting (which appears to work fine for
you at the command line), and all zenmap is doing is displaying nmap's
output.

The encapsulated packets thing still sounds weird though.

Did you select WinPcap 4.02 when you installed Nmap using the Windows setup
binary? If you didn't, that would explain why you had to install it
afterwards. If you did, that makes me wonder why it failed, as it should
install and work fine on XP SP2.

Nmap version 4.60 ( http://insecure.org )

I'd be surprised if there were an old version of nmap on this
machine, though.

I get the same bogus encapsulation running nmap from the command
shell. Doesn't seem like it's zenmap related.
