I have a set of systems with dual ports.=20
One set of ports is set as an internal network, the other are on an
One of these systems is a "server" for the internal network. For example
all syslogs go there.
My problem started with the syslog on the master trying to resolve the
It failed of course, since they are not served by any name server,=20
but it takes time for the resolver to get the answer.
I'd like to set up a name server on the master. I'd like it to listen
only on the internal network (easy),
But I also want it to immediately reply with a failure on any
(syslog 1.4 has a -x flag that causes it to not try to resolve
addresses, this is the behavior=20
I want all resolvers to get, whatever they are, so my guess is I need to
do it in named=20
and not in the resolvers)
The reason I'd like it to fail, is so I don't have to maintain a real
zone for the=20
internal network, being of no interest to anyone.
Any ideas how to achieve that would be great.
