[REBOL] `Pinging' my net ---

From: dness::home::com at: 24-Oct-2001 12:56

My home net has half a dozen machines and network-attached printers and storage all of which may be up or down at any particular point. I'd like to be able to detect which machines are `up' and write REBOL code that allows me to do various things---starting with status inquiries---to the machines that happen to be up. My machines are all assigned permanent IP #'s, so I am happy to make a list of `possible addresses' that might be up. Indeed I have `command line' code that pings all of the machines and reports back. but, I'd like some REBOL code that would let me detect which machines are available at any particular moment, to serve as a starting place for expansion into code that might perform various useful cross-net functions. Where should I look to get started?
