Re: dhcp-dns problem
Craig,
I did find this error in /var/log/messages and looked it up, the mails I've
read seem to indicate that the name server can't find this domain?
However, everything(nslookup) seems to work fine. The messages log file is
listed below if you feel like looking at it.
===>>> "Sep 8 04:00:07 srfs1 named[8222]: sysquery: findns error
(NXDOMAIN) on dns1.mydomain.com?"
Do you think this message is related to dhcp-dns not being able to update the
domain?
The DNS server setup scenario I'm running is:
=========================================
1) I have an internal(on a private IP address subnet only connected to
internet via NAT/MASQ) DNS name server acting as a master for mydomain.com.
2) I have an external(on the internet)DNS server acting as a master for
mydomain.com.
3) The internal DNS server serves all the internal clients, and has
forwarding setup so that it can forward requests to an outside name server.
4) The external DNS server serves the internet clients, and does not do any
forwarding, and does not know about the internal machine.
5) The way I understand it, is that the internal DNS name server should never
query the up level .com server for mydomain.com because it is the master for
that domain.
Does the info. below help? Is there any specific file or log that could help
to come to a conclusion?
Is there any where else besides /var/syslog or /var/messages that I can find
logs for dhcp-dns?
Can you point me to anyone/anyplace else that might be able to help?
Can you think of anything else that might help me out?
Thanks for the help...
---Dean.
