My sanity requires top-posting: See your very last sentence: You go to an HTTP port at a non-routable address which should be on the box. Usually on a yellow sticker. Now I've never tried to program that interaction but I bet it could be done. For comparison, biggish Juniper routers are configured by salt/saltstack these days. Just like your linux server farm.
But maybe start trying with wget or curl. Work your way up the language hierarchy. HTH.
