How to configure DNS for a local LAN (at least I think I want DNS)

There is a LAN party that I help run and we are trying to figure out how to set up a DNS server to basically auto forward any webpage requests to our main server webpage. (if there is a different way to do this without setting up a DNS server I am all ears)
There is no internet connection at the place we LAN and there would only be 1 DNS server (most guides I have looked at have a primary and secondary). The main server all ready has a dhcp up and running, and apache.

Thank for any help.

Here are the files I have made and the last is the output of trying to do a nslookup.
There is something wrong but I don't know what it is or where it is. If anyone can point out any problems I would appreciate it.

db.mtvlan

Code:

$TTL 21600

@      IN      SOA    localhost. root.localhost. (

00000005; Serial Number (not a date)

21600 ; Refresh every 6 hours

3600 ; Retry every hour

1728000 ; Expire every 20 days

21600 ) ; Minimum 6 hours

IN      A      10.10.0.1

;



*      IN      A      10.10.0.1

db.0.10.10

Code:

@      IN      SOA    localhost. root.localhost. (

00000005; Serial Number (not a date)

21600 ; Refresh every 6 hours

3600 ; Retry every hour

1728000 ; Expire every 20 days

21600 ) ; Minimum 6 hours



1      IN      PTR    mtvlan.com

named.conf

Code:

zone "mtvlan.com"{

type master;

file "db.mtvlan";

allow-update { any; };

allow-transfer { any; };

allow-query { "any"; };

notify yes;

};



zone "10.10.0.in-addr.arpa" {

type master;

file "db.0.10.10";

allow-update { any; };

allow-transfer { any; };

allow-query { "any"; };

};

after I start up named

Code:

penguin:/etc/bind# nslookup mtvlan.com

Server:        127.0.0.1

Address:        127.0.0.1#53



** server can't find mtvlan.com: SERVFAIL

You should not need these lines in your named.conf..

Code:

allow-update { any; };

allow-transfer { any; };

Also in the ptr record you need to put a period after the domain.

Code:

1 IN PTR mtvlan.com.

In you A record try to remove..

Code:

IN A 10.10.0.1

And leave

Code:

* IN A 10.10.0.1

ok this is how my stuff looks now

db.mtvlan

Code:

$TTL 21600

@      IN      SOA    localhost. root.localhost. (

00000005; Serial Number (not a date)

21600 ; Refresh every 6 hours

3600 ; Retry every hour

1728000 ; Expire every 20 days

21600 ) ; Minimum 6 hours

*      IN      A      10.10.0.1

db.0.10.10

Code:

$TTL 21600

@      IN      SOA    localhost. root.localhost. (

00000005; Serial Number (not a date)

21600 ; Refresh every 6 hours

3600 ; Retry every hour

1728000) ; Expire every 20 day

1      IN      PTR    mtvlan.com.

named.conf.local

Code:

zone "mtvlan.com"{

type master;

file "db.mtvlan";

allow-query { "any"; };

notify yes;

};



zone "10.10.0.in-addr.arpa" {

type master;

file "db.0.10.10";

allow-query { "any"; };

};

I am seeing no change in anything. I have even gone through the default named.conf and commented out all pre entered zones.

Did you restart named after you made the config changes?

yeah, I just killed it and restarted it.

Here I just slapped together a basic config that will work..

named.conf

Code:

zone "." {

        type master;

        file "/etc/bind/db.root";

};

db.root

Code:

$TTL    3H

@      IN SOA  ns.    root(

        2005101100      ; serial (yyyymmddnn)

        3H          ; refresh

        20M        ; retry

        3H          ; expiry

        3H )        ; minimum

@      IN      NS      ns.

ns.    IN      A      127.0.0.1

*      IN      A      10.10.0.1

The test...

Code:

Pinky:/etc/bind# nslookup

> server localhost

Default server: localhost

Address: 127.0.0.1#53

> google.com

Server:        localhost

Address:        127.0.0.1#53



Name:  google.com

Address: 10.10.0.1

> cnn.com

Server:        localhost

Address:        127.0.0.1#53



Name:  cnn.com

Address: 10.10.0.1

Thanks a ton. It works perfect.
