How to do it...

1. To test the db_import command, we will use the nmap command, a free security scanner, port scanner, and network exploration tool, with the -oX option to save the result to an XML file. Here is the syntax used to scan the Metasploitable 3 target machine:

nmap -Pn -A -oX report 192.168.216.10

1. To import the scan report, you can use the db_import command followed by the path to the report you want to import:

msf > db_import /root/report
[*] Importing 'Nmap XML' data
[*] Import: Parsing with 'Nokogiri v1.8.0'</strong>
[*] Importing host 192.168.216.10
[*] Successfully imported /root/report

Alternatively, you can run the db_nmap command directly from msfconsole, and the results will be saved in your current database. The db_nmap command works the same way as the regular nmap command:

msf > db_nmap -Pn -A 192.168.216.129
