Allow closing shellinabox
The shellinabox service that runs on port 4200 is not secure enough, for a number of reasons:
* it accepts non-TLS traffic
* no multifactor authentication
* no battle-tested frontend webserver like nginx before it
Instead of fixing all of these, perhaps just allow to disable this service like you allow for other services.
Just wanted to echo this great suggestion. Having this port open (without the ability to close it) poses a lot of security issues.
Currently, any effort for closing this port requires 'sudo' privilege, which Cloudways does not allow for obvious reasons.
