I had the following problem on OpenBSD 4.1.

OR

nmap -A -P0 -vv 192.168.10.5

gives me:

Starting Nmap 4.22SOC7 ( http://insecure.org ) at 2007-10-22 20:43 CDT
Warning: File ./nmap-services exists, but Nmap is

reasons.  set NMAPDIR=. to give priority to files in your local directory

However the following works

nmap -sT -P0 -vv 192.168.10.5

Nmap does an ARP scan of directly connected Ethernet hosts even if -P0
is used. See http://insecure.org/nmap/man/man-host-discovery.html. But I
don't know why the ARP scan would fail when the connect scan works.
Please send the output of

nmap -sS -P0 -d2 --packet-trace 192.168.10.5
