No, the operating systems can talk together, though you're probably better off using something like wget or depending on your linux distro.
I recently managed to compile nwnx (a 32 bit app) on a 64 bit ubuntu box and it seems to be running alright for the moment. Honestly the best place to start is on the nwnx.org forums, maybe see what you can find about nwnx_easy. Fireboar designed that setup for linux noobs, of which I am still one.
Really though if you just wanna reset the server every 6 hours or so, sounds like you could accomplish this with a shell script and a cronjob.
