Thanks for your pull request! Before this pull request can be merged, it must pass the checks of our automated linting tools.

We use Rubocop and msftidy to ensure the quality of our code. This can be ran from the root directory of Metasploit:

rubocop <directory or file>
tools/dev/msftidy.rb <directory or file>

You can automate most of these changes with the -a flag:

rubocop -a <directory or file>

Please update your branch after these have been made, and reach out if you have any problems.

Thanks so much for the change!
This is an older module, so it is not quite up to the normal linting we hold, now. I know you have not changed all of it, but we'd really appreciate it if you could run this through Rubocop just to see how much of a lift it would be to bring it up.

The RPORT is not registered here, so it could have a default already?

[NtAlexio2]

yes it has default value as you can see in the below, which is 445:
