I sent a message to the list earlier regarding this, but am not sure it went through. Please excuse if it is already in circulation I am trying to learn to use nmap. I have installed nmap/zenmap (latest version for win) with winpcap when I run any scans I have to use the --unprivileged option since I am running with a wireless card which uses ppp0 All scans return the same error sample scan: nmap -T4 --version-light -sV -F -O c--unprivileged scan.target.com constant error output (regardless of target) TCP/IP fingerprinting (for OS scan) 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 versions, you may be able to take iphlpapi.dll from another system and place it in your system32 dir (e.g. c:\windows\system32). QUITTING!
A limitation of Nmap on Windows is that in can only do raw-packet scans on Ethernet devices. That's why you have to use --unprivileged on your ppp0 interface. Unfortunately that means you can't run OS scan either. The error message is misleading. It really should say "TCP/IP fingerprinting (for OS scan) requires raw packets" or something like that. The error message is assuming that the only way you could fail to have "root privileges" (in terms of raw packet sending) on Windows is that WinPcap is not installed. However you have shown that it can also be caused by the use of --unprivileged. The error message should not be too hard to fix. Does anyone have an opinion as to the wording, or can you think of any other corner cases to cause this error?
