How to create master+forwarder dns server in linux
Hi Team
I have created one new dns server in lab and its working properly.
Earlier we were using another dns server for lab pc's as 10.20.30.xx. which is outside the lab premises.
now issue with newly created as its not resolving query as previous. I am told by some to use forwarder option for this.
I want to use previous dns server as forwarding if newly can't resolved the queries
so i am looking to create master+forwarder dns server at new dns server so we could get easily replication.
can anyone clarify how to create forwarder option in named.conf at newly server?

You don't bother telling us what version/distro of Linux you're using
You don't bother telling us what you mean by "not working", such as giving us ANY error messages, etc.
You don't say WHICH of the TWO links I sent you that you tried, or what the results were
You don't acknowledge that there were over TEN MILLION other hits that you COULD have looked up/tried, since you didn't provide any of the other details mentioned.
Ask a clear question and provide details, or look things up on your own.
Its not forwarding queries to forwarder dns server.

You were given things to check/try before, but you *STILL* don't say what you did to generate that message. One of the two links I looked up for you previously has troubleshooting tips...did you try them? Did you check your firewall/iptables rules? Did you check your configuration, since if you don't have it set correctly, forwarding won't work??
Again, unless you post ERRORS or give us any details, THERE IS NOTHING WE CAN TELL YOU. It's failing for SOME reason, but you don't share your configuration, and say you're not getting any errors at all. Since that's the case, what do you think anyone can tell you?? Since you're using Red Hat Enterprise, you should contact Red Hat support...you are PAYING FOR RHEL, RIGHT????
