You might want to give it a shot. I bought the o'reilly books too, but the how-to really does cover stuff very quickly. I had always thought dns was a minefield, but once you look at it logically for your network it all makes sense fairly quickly. I guess I'm a month into it now from my first stab at it. It's well worth the effort I do have to say. Best of luck Bry -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
