NmapFormula class

nmap — what a node can see of the network around it.

The view from inside the fleet, which is the one that answers "can this node actually reach that port?" without guessing from the outside.

Worth installing deliberately rather than by default: a port scanner on a server is a tool an intruder is glad to find, and on some networks running one is itself an event. That it takes an explicit formula run — recorded in the audit trail with the principal who asked — is the right shape for it.

inherited
statusStepFor(String osName) → CommandStep?
The probe that says whether what this formula manages is running, or null when it manages nothing that runs.
inherited
stepFor(FormulaAction action, String osName) → CommandStep?
