Special note about Nmap, DNmap, Metasploit, and output options dnmap can be used inside Metasploit to automatically insert results
into the MSF database. However, even with the -oA option, nmap XML
output is not generated. It is better to use nmap (within MSF) with -oA
to generate all three output types, then import the results into MSF
from the XML file.
