Thanks a lot for the help, but none of those links have anything to do
with my error message.  I have done the google/FAQ thing and got
nowhere.

I suspect (and this is just a hunch) that it has to do with the virtual
interfaces.  I have had issues with them in the past and even if it is
not the problem, maybe someone can clarify this for me.  I moved this
exact nagios config over to another box on the same network with the
same gateway but with only one IP and it is working fine.  I was under
the impression that all it takes to add a second IP to a redhat box is
to configure ifcfg-eth0:2 with an IP, network, broadcast, and netmask,
assuming that the second IP has the same gateway as the first.  For the
most part this works, but occasionally I come across a problem where the
server hears a request on one interface and then responds to the request
from another interface.  I found this by debugging an access server that
was sending radius requests but not getting answers back.  

Why would this be?  Is there a route that needs to be added?  Could this
cause the failure to install socket filter?

I must be missing something simple.

Thanks for any insight,

Brad
