Hi Barry,

Thanks for your quick response.  I am going to make those changes and
restart network services in a few minutes.

My question now is, how can the box be responding to all those IPs with
the ifcfg-eth0:x files clearly not what they should be?

Not a crucial question, but one of interest.

Thanks again,
