I have installed bind with yum install bind bind-chroot.I am having query timeouts due to no ipv6 connectivity.Is there a way to re-compile and not loose the chroot structure?Or is there another way to disable ipv6 lookups?Example of issue resulting in ipv4 query timeout:

I am working on setting up a bind 9 nameserver that will be responsible for serving up DNS records for my internal network and publicly for my web server. My configuration is below:
Firewall Gateway (Ubuntu Server 9.10) ---> switch ---> internal servers (ubuntu server 9.10 and mac os x server)
The internal servers are all on the same subnet, so DNS, web and mail will all be on the same subnet of private IPs. Each internal server is mapped with SNAT to a public IP address. And the DNS server only has port 53 forwarded to it.I am trying to figure out the best way to set up my nameserver so that it can provide records for my internal servers based on private IP addresses, and then provide records to the public for my internal servers based on their public IP addresses. I had a few questions on this:
1) Is this the correct way to think about my setup, or is this typically done in another way?
2) Does anyone have recommendations on the specific configuration I should follow?
3) Are there specific references I should look into as well?
From a scan with nmap,I saw that,on my desktop,3 services were visible,ssh(which I don't want to disable),rpc-bind and smtp.As far as I know rpc-bind and smtp aren't needed on a desktop pc(I don't plan on having a mail server,at least on this pc),but before disabling something I need,I am asking it here-do I need them for some vital service?I am running OpenSuse 11.

I hear that "The working directory is not writable" is nothing to worry about and is just something that is complains about for no reason, but I can not decipher.

I had centos 5-5 server with 6G of RAM and 4 core cpu 3GHZ i installed bind 9.7.1-p2 on my server with multi thread support there are a lot of dns requests on my server , about 2500 Packets/sec and 3Mbit UDP traffic but my server response week to most of them.
For example when i use nslookup or dig command to query Yahoo.com the response from server maybe deliver about 5 Sec or become timed out , but sometimes response time less than 1 sec!
I don't know why, perhaps kernel works week so i decided to do the following :
But the problem didn't solved
I previously had Freebsd with same version of bind and same configuration and everything worked fine.
I have been a BSD guy for years, but I am now shifting over to CentOS for my first server build.
So far so good, all has been relatively painless and in fact a heck of a lot simpler than I anticipated!
Everything seems to have gone ok except a small problem with Bind. At some point during setup, I accidentally ran "yum remove bind-chroot".
When I tried to run "yum install bind-chroot" I got told "No package bind-chroot available" which was odd.
Anyway, I managed to find the rpm for bind-chroot and installed it that way. Now I see that there is a bind update available
Unfortunately the rpm I installed now has a dependency for the current version of bind which I can see being a headache everytime bind needs updating.
So, can anyone help me get back bind-chroot the proper way? code...
