Then start your Metasploit 2 VM, it should boot now. The major purpose why use of such virtual machines is done could be for conducting security trainings, testing of security tools, or simply for practicing the commonly known techniques of penetration testing. 15.

In the online forums some people think this issue is due to a problem with Metasploit 6 whilst Metasploit 5 does not have this issue. This could allow more attacks against the database to be launched by an attacker. Armitage is very user friendly. This particular version contains a backdoor that was slipped into the source code by an unknown intruder.
When we performed a scan with Nmap during scanning and enumeration stage, we have seen that ports 21,22,23 are open and running FTP, Telnet and SSH .
