Re: Inscrutable Winpcap error
From: "Eddie Bell" <ejlbell () gmail com>

The error message could be better but it seems to be because of  '-sS
--unprivileged'

-sS is a privileged scan type so cannot run in unprivileged mode. I
get the same error in vista but it is fixed by changing the scan type
to -sT or removing  '--unprivileged'

I just today downloaded and installed the latest Windows binary of
 ncap.

 C:\PROGRA~1\Nmap> nmap --version
 Nmap version 4.60 < http://insecure.org >

 I try my first scan and get this:

 C:\PROGRA~1\Nmap>nmap -p 2000-2031 -sS 192.168.155.22 --unprivileged
 You requested a scan type which requires that WinPcap version 3.1 or
 higher and iphlpapi.dll be installed. You seem to be missing one or
 both of these. Winpcap is available from http://www.winpcap.org.
 iphlpapi.dll comes with Win98 and later operating sytems and NT 4.0
 with SP4 or greater.  For previous windows versi ons, you may be able
 to take iphlpapi.dll from another system and place it in your
 system32 dir (e.g. c:\windows\system32).
 QUITTING!

 I don't know how to check the level on Winpcap installed, but there
 is a winpcap-nmap-4.02.exe in my nmap directory

 I am running WinXP, SP2. What gives?
