This will be short: As far as I can tell, this is all dhcping will do:
Not that it’s bad or somehow an underperformer. Reading through the man pages and the home page, that’s all dhcping was intended to do — check that a dhcp server is still running.
It does give the impression of a piece of a larger puzzle though. The man page says it returns either 0 or 1, reflecting the state of the server.
I’m no programmer, but methinks that could be useful in a larger application.
But alas … that’s all there is to it. Quite possibly the simplest program yet. 😉
