BIND overwrites resolv.conf on boot

I am still struggling to learn BIND. Thanks to all of you have helped
me up til now. Let me try to break the problem in to workable pieces.

First Question:

I didn't get an answer when I ran dig for my domain name. I edited
resolv.conf and got the right answer, but when I reboot, resolv.conf
is overwritten with the original file!

I have examined lines /var/log/syslog that might be relevant:

Oct 17 08:07:58 jupiter named[2206]: starting BIND 9.2.4 -u bind -t /
var/lib/named

loaded serial 2008100701
Oct 17 08:07:58 jupiter named[2206]: running

However, I haven't found any clues here about what is overwriting
resolv.conf.

Best to all,

Are you using some dialup connection while you're 'binding'?
Usually the pppd script change the dns to their own ones while you're
connected.

cheers

I have never heard about BIND overwriting resolv.conf. AFAIK, BIND does
not care about resolv.conf at all. What makes you think that BIND is the
one ?

My first bet would be the network setup. It could be a DNS setting in a
static interface configuration, or the DHCP client, or pppd for a PPP
connection. As you did not mention the distribution and connection you
use, I cannot say more.

You're right, I have no reason to think that it's BIND.

I have a cable modem connection to RCN, which has assigned my the
static IP address 207.237.37.110.

I have a Dell Truemobile 2300 Broadband router that performs NAT, and
is configured to permanently assign 192.168.2.2 to the computer that
runs my DNS server.

ifconfig outputs:

eth0 Link encap:Ethernet HWaddr 00:01:03:E1:55:98
inet addr:192.168.2.2 Bcast:192.168.2.255 Mask:

Does this help?

Thanks!

I am going to guess the values you entered into the eth0 setup is what
is overriding your /etc/resolv.conf.

You may want to improve your Usenet experience by reading
http://www.catb.org/~esr/faqs/smart-questions.html

Providing your linux distribution/release/desktop manager/...
might get you more precise/detailed answers.

Example for Mandriva Linux 2008.1, setting
DNS1=192.168.1.131
DNS2=208.67.222.222
DOMAIN=home.test
in /etc/sysconfig/network-scripts/ifcfg-eth0
creates
nameserver 192.168.1.131
nameserver 208.67.222.222
search home.test
in /etc/resolv.conf

Or if you have an interface that's dhcp.
bind doesn't touch resolv.conf.

Via dhcp. dhcp is overwriting your resolv.conf.
