Hi !
I have to phase out 3 of my 5 secondairy 8.3.3 bind servers in a closed
(not internet connected) network.
Since I have no complete control over the configuration of the clients
it is still possible that some machines will try to resolve stuff on the
"phased out" machines, I thought it would be a good idea to make make
the old boxes forwarders to my primary/new secondairies and log the
queries that are done to them in order to determine who is still using them.
The problem is that something goes wrong with the forwarding (i think).....
Whenever I try to resolv something using the forwarding server, I'm
getting a "SERVFAIL" so nothing is found.
When I look on in the querylogging on the the server that the forwarder
forwards to (i.e. my new secondairy) I see the following :
First a query direct to the new secondairy
17:57:45.590XX+/145.78.156.10/lr006b01.lr006.kpn-post.nl/A/IN
now a 'forwarded query'
17:58:30.972 XX+/145.78.156.10/./NS/IN
the ip-address in these lines is my workstation.
The questions are :
-Isn't the 'forwarder' supposed to contact the new seconairy instead of
my workstation ?
-Why does my workstation seem to ask for an empty record ?
-Is there a better solution for what I want to achieve ? Phasing out by
forwarding / logging queries ?
=========
named.conf on "forwarder"
options {
directory "/etc/bind";
//forwarders { 145.78.151.79; 145.78.124.229;};
forward only;
forwarders { 145.78.124.229; };
};
zone "." in {
type hint;
file "db.cache";
};
zone "0.0.127.in-addr.arpa" in {
type master;
file "db.127.0.0";
};
Thanks in advance for any comments on this matter,
