Yes, in a sense it is confusing...to explain, the fc3 box, toy or
whatever lol will just be a synced copy of the fc2 box when I'm done. I
don't really want to get into the syncing yet more questions to come on
that later. But, I only have one static public ip 209.205.179.141. The
fc2 box is 10.0.0.10...the fc3 box is fc3 is 10.0.0.12. At this point,
it's easier just to shut one box down while I work on the other. They
both have named pointing to their own respective box. when sendmail is
running in the fc3 box...the fc2 box is shutdown. it's the only server
running @rivers-bend.com. when I am in the fc3 box(10.0.0.12), and run
$host rado at rivers-bend.com , it says it's on 10.0.0.12 so it's for real
there. Another thing, selinux is disabled... and run nmap -sT rbmain2
(the fc3 box), just the minimal ports are open,
22,23,25,53,110...think..maybe 111 as well; that's bout it. looking at
the nmap for this machine(fc2) wow lots of ports open!

The only times my computer fails to come on is after I shut it off.
