Best $100 I ever spent (for the 2 volumes).  Within 15 minutes of
receiving them I'd say they've paid for themselves.  I opened Volume 1
up, and it fell to a page showing a function to find out ALL the IP's
on ones local host, even if you have multiple interfaces (or aliased ones)
I'd heard experienced Unix coders doubt this was even possible, at least, 
not without some crufty programming.

No doubt they hold other hidden treasures.

Ciao
