DNS blues....

[shylock_1]

Hi Forum

(ps read 3w = world wide web)

A consistent problem with DNS set up gave sever head ache even though this damm thing work but it does not do what I like to do or see. When I try use apache server with my specified url that onami.co.uk with 3w get kicked in from the DNS hosting company which is uk2.net I wonder where I am going wrong?

Any way I have following setting for my DNS server.

0/ On Red hat Enterprise 6 server

1/ I have fully registered domain i.e. 3w.onami.co.uk with company 3 w uk2.net on their server conanical name exists.

2/ I do NOT have static IP address at my premises instead dynamic address with router holding ip 192.168.1254 and allocating a IP to my DNS server 192.168.1.100

3/ In /etc/named.conf file modified and to added zone record for 3w.onami.co.uk forward and onami.rev.zone for reverse zone check two files stored in /var/named/data/ directories.

4/ when I ran “service named restart” I get response Stopping named [OK] starting named [OK]

5/ After analysing /var/log/messages I get following details

tail /var/log/messages

6/ When I ran dig command with 3w.onami.co.uk I get following details:

Can you post what your DNS zone looks like? Would help. Also is 83.170.69.51 your web servers ip address?

Hi,
eaven if I haven't seen the configuration yet, there some things in the log that seem to be wrong:

Aug 29 13:00:47 hawk named[5113]: zone onami.co.uk/IN: loaded serial 2011082700
Aug 29 13:00:47 hawk named[5113]: zone 3w.onami.co.uk/IN: sending notifies (serial 2011082700)

May I'm wrong but the way I understood bind you should only have the zone "onami.co.uk" in witch "w3.onami.co.uk" and all other sub-addresses are defined.
Like add:
www CNAME @
into your onami.co.uk zone and deactivate the zone w3.onami.co.uk.
You also should change the serials of the zones, they must never be the same. (serial 2011082700)

If you only have the zone "onami.co.uk" I misinterpreted the log.

You can also use the command host or nslookup to check your DNS settings.

host w3.onami.co.uk localhost

Will tell you what the server you are on answers.

host w3.onami.co.uk

Will tell you what your default server answers.

Example:

user@Server:/etc$ host www.zombynet.local localhost
Using domain server:
Name: localhost
Address: 127.0.0.1#53
Aliases:

www.zombynet.local is an alias for zombynet.local.
zombynet.local has address 192.168.1.105
