The underlying principle that defines how a TCP connect scan is performed by the dmitry command is the same as was previously discussed with other tools. The usefulness of DMitry mostly lies in its simplicity in comparison with other tools. Rather than managing several configuration options, as we need to with Nmap or Metasploit, we can easily launch DMitry by specifying the appropriate mode and passing it the target IP address. It quickly scans the most commonly used 150 ports and outputs the values of all of the open ports among these.
