Hi
Do you really need to use bind perhaps dnsmasq would be a better
option for you.

SUBJECT: [CentOS] Configure a local DNS caching nameserver: partial
success

Hi,
The subject says it all. On my "server" machine in the local LAN
(192.168.1.252 in a 192.168.1.0/24 network), I setup Bind. I
installed
the 'caching-nameserver' package, which provides a set of
configuration
files for Bind so it can be used as a caching nameserver out of the
box.
On the server :
I start bind (service named start), and try it out.
# host www.google.fr 127.0.0.1
Using domain server:
Name: 127.0.0.1
Address: 127.0.0.1#53
Aliases:
www.google.fr is an alias for www.google.com.
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 209.85.227.99
www.l.google.com has address 209.85.227.103
www.l.google.com has address 209.85.227.104
www.l.google.com has address 209.85.227.147
Which tells me basically that my DNS server works.
Now I'd like all the other machines on the network to use this local
DNS
server instead of my ISP's DNS. First thing, I know Bind uses port
53,
so I take care to open that port on the server as well as on the
other
machines in the network. Then, I try to use my local DNS server
manually
on one of the machines, but I only get this :
$ host www.google.fr 192.168.1.252
;; connection timed out; no servers could be reached
Since I'm rather new to Bind, this leaves me a bit clueless. I'm
currently busy reading "DNS & Bind" from O'Reilly, but this 750 page
book is ideal for blocking my terrace door on windy days, and the
problem is not absence, but wealth of information.
Any suggestions ?
Niki
