I'm not even sure if I am asking this correctly, so please let me try and explain a little more. I've had minimal Perl experience and am trying to learn.

I am attempting to write a harvester that will move across my network so that I can keep an eye on what machines are up.

Essentially what I would like to figure out how to do is...

If I have a domain... foo.com and I have two other machines that exist as bar.foo.com and baz.foo.com. If I tell my script to look at foo.com it will print out some form of output showing that bar and baz exist.

I have been investigating Net::DNS, Sys::Hostname and so on in an attempt to figure this out on my own and after writing about 4 or 5 scripts that are useful, I still have not been able to accomplish what I am trying to do.

If anyone can point me to where I should go to learn how to do this or help me with how to actually write it, I would grateful.
