Cool tool, I'll check it out. Guess, I should explain myself a little better. I'm trying to create my own "auto" audit CD for teaching myself more. I kinda know what I wanna do, but still need to figure out how to do things.

The first thing I wanted to do was to make a bootable cd (done)
Second thing I wanted was to make the cd scan to see what live IP's are out there and put into a text file (currently working on).

Command line tools are best, since it will need to be scriptable. Thats why I wanna figure out the best way to find all live subnets first. (kinda funny to have it scan the entire class C, if I only have 3 or 4 boxes on my test network).

Hope this gives a little more insight into my thinking.

thanks again
