Basic theory

There are vulnerabilities and payloads.

Payloads would typically give us a shell on the remote system. Android, Linux and Windows require different shells.

You can attach via 'reverse' or 'bind'. A 'bind' is best, as the user opens a port, and you connect. Mostly, you have to use 'reverse', which opens a connection to you.

Note this one:

9200/tcp open tcpwrapped

Apparently that's 'elasticsearch', so in metasploit we can do:

search elasticsearch

If you want to use 2, use 2 or use/multi/ela then tab out.

set rhost 172.18.3.26

The remote port's already set at this point.

We've so far done use, rhost, and port.
