I should have read more carefully your output. Refer to: "Skipping SYN Stealth Scan against 10.1.20.90 because Windows does not support scanning your own machine (localhost) this way." Nmap does recognize your local host and acts accordingly (by skipping your localhost). This does not actually seem to be the problem. I cannot seem to reproduce the errors. Could you please provide the exact arguments, along with Nmap, Winpcap and Windows version. Lastly, the output from 'ipconfig /all' could further assist in troubleshooting.

Brett, Thanks for the reply... i figured the limitation was windows, but one may often want to easily scan their own range so it gets more tricky.... I hate to crash just because something Windows can't handle it if Nmap could just say "Windows can't do X.... we are excluding Y". That is why i was thinking an exclusion.... I tried your example as-is and got the following: C:\Util\Nmap>nmap -sS -p80 -P0 192.168.1.1/24 -packet_trace -n -S 192.16 8.1.108 -e eth0 Starting Nmap 4.21ALPHA4 ( http://insecure.org ) at 2007-04-17 16:21 Central Day light Time NmapArpCache() can only take IPv4 addresses. Sorry QUITTING! Then I adjusted for my IP address and go the same thing: C:\Util\Sniffer\Nmap>nmap -sS -p80 -P0 10.1.20.1/24 -packet_trace -n -S 10.1.20. 108 -e eth0 Starting Nmap 4.21ALPHA4 ( http://insecure.org ) at 2007-04-17 16:24 Central Day light Time NmapArpCache() can only take IPv4 addresses.

That's a good point that maybe nmap should exclude itself, or use some sort of work around. For now, see if the following example works: *nmap -sS -p80 -P0 192.168.1.1/24 -packet_trace -n -S 192.168.1.108 -e eth0 * ref.: http://seclists.org/nmap-dev/2006/q1/0318.html On 4/17/07, alan () ajsquared us wrote: > > When I try and scan a subnet 1.2.3.* that I am on I have found Nmap > seems to quit early.
