hello one and all,

i am setting up a centos 5 server and i can't quite get bind/named to
work properly. actually, it works great on the linux server, but the
other private intranet computer behind the linus server do not resolve
domain names. i have the client computers default gateway and DNS
server pointing to the linux server ip, i.e., 192.168.0.3. but the
client computer are not seeing the dns service on server.

so basically, bind/named is working fine on the server itself, however,
the client computer accessing the dns server are not able to resolve
domain names. iptables and routing are working and not the cause on the
server and also, pinging a hard ip off the client computers is working
fine. just dns is not working on the client computers. please help.
thank you in advance.

Fire up a packet sniffer, and see what the query/response look like on
the wire. Look at the DNS server setup, and make sure it is listening
on the _network_ interface - eth0 or eth1 as appropriate (and not just
the loopback interface).

well,

under the file

/var/named/chroot/etc/named.caching-nameserver.conf

i added the line

acl localnet { 127.0.0.1; 192.168.0.1/24; }

and then changed the following two lines to use this acl localnet as:

options {
listen-on port 53 { localnet; };
...
allow-query { localnet; };
}

also under:

view localhost_resolver {
match-clients { localnet; };
match-destinations { localnet; };
...
}

these changes to this file did the trick. very tricky, really. thanx
for your help.
