In version 5.0 of Nmap is a database of Fingerprint (fingerprints) that 
are scannings made by others and submitted to the site of nmap
(Nmap - Free Security Scanner For Network Exploration & Security Audits. 
<http://nmap.org/>), forming a basis for recognition of systems and 
equipment.

For this, run some commands at the shell:

Step 1:*

# gedit /usr/sbin/update-nmap-os-db*

Step 2:

set -e

SRC="http://nmap.org/svn/nmap-os-db"
DEST=/usr/share/nmap/nmap-os-db

umask 022
if which wget >/dev/null ; then
DL="wget -O $DEST $SRC"
elif which lynx >/dev/null ; then
DL="eval lynx -source $SRC >$DEST"

else

echo >&2 "nmap-os-db: não foi localizado o comando wget ou lynx 
(Portuguese)"
echo >&2 "nmap-os-db:was not found wget or lynx (English)"
exit 1
fi

if ! $DL ; then
echo >&2 "nmap-os-db: download falhou (Portuguese)"
echo >&2 "nmap-os-db: download failed (English)"
rm -f $DEST
exit 1
fi

echo "Terminado"
echo "Done." *

Step 3*
# chmod + x /usr/sbin/update-nmap-os-db
Then just run at any time, as root or sudo and its database of 
fingerprints will always be updated.

Note: You discover new machinery, equipment and operating systems may 
make additional fingerprints or correct them. For this, go to link:
