Can I use bind9 to resolve only ONE hostname in a zone?
Hi there,
I have the following problem.
I have a
Debian server with
bind9.
I can also use my ISP DNS server through the internet box (192.168.1.1).
I would like to
fool my client workstation to a local machine when they query for one specific hostname within a domain.
I want to let the ISP DNS do the job for any other request.
For example:
- If they query mail.google.com, I want to point that to 192.168.1.40.
- If they query anything else in google.com, I want to let 192.168.1.1 do the resolution.
- If they query anything else in any other domain, I want to let 192.168.1.1 do the resolution.
So far I setup bind9 on my
Debian server.
I created a zone for
google.com and I successfully redirected
mail.google.com to 192.168.1.40.
But how can instruct bind9 to transmit any other request to the next DNS (192.168.1.1)?
Thanks for your help.

LEARN ABOUT FREEBSD
nos-tun
NOS-TUN(8) BSD System Manager's Manual NOS-TUN(8)
NAME
nos-tun -- implement ``nos'' or ``ka9q'' style IP over IP tunnel
SYNOPSIS
nos-tun -t tunnel -s source -d destination -p protocol_number [source] target
DESCRIPTION
The nos-tun utility is used to establish an nos style tunnel, (also known as ka9q or IP-IP tunnel) using a tun(4) kernel interface.
Tunnel is the name of the tunnel device /dev/tun0 for example.
Source and destination are the addresses used on the tunnel device. If you configure the tunnel against a cisco router, use a netmask of
``255.255.255.252'' on the cisco. This is because the tunnel is a point-to-point interface in the FreeBSD end, a concept cisco does not
really implement.
Protocol number sets tunnel mode. Original KA9Q NOS uses 94 but many people use 4 on the worldwide backbone of ampr.org.
Target is the address of the remote tunnel device, this must match the source address set on the remote end.
EXAMPLES
This end, a FreeBSD box on address 192.168.59.34:
nos-tun -t /dev/tun0 -s 192.168.61.1 -d 192.168.61.2 192.168.56.45
Remote cisco on address 192.168.56.45:
interface tunnel 0
ip address 192.168.61.2 255.255.255.252
tunnel mode nos
tunnel destination 192.168.59.34
tunnel source 192.168.56.45
AUTHORS
Nickolay N. Dudorov <nnd@itfs.nsk.su> wrote the program, Poul-Henning Kamp <phk@FreeBSD.org> wrote the man-page. Isao SEKI
<iseki@gongon.com> added a new flag, IP protocol number.
BUGS
We do not allow for setting our source address for multihomed machines.
