DNS help

[ggohdin]

Hi, im prety sure this is a dns problem. anyways

when I nslookup google.com as an example I get:

Server: 192.168.1.1
Address: 192.168.1.1#53

Non-authoritative answer:
Name: google.com
Address: 74.125.67.100
Name: google.com
Address: 74.125.45.100
Name: google.com
Address: 209.85.171.100


When I use dig `hostname` i get:
; <<>> DiG 9.5.1-P1 <<>> server1.agama.com
;; global options: printcmd
;; Got answer:

Now the weird thing is ns1.gldn.net is deffinatly not my ns1, I donno where its even from.

But if I change my resolv.conf file from ip 192.168.1.1(gateway ip) to 192.168.1.4(server ip)

I get this when I use "dig `hostname`:

; <<>> DiG 9.5.1-P1 <<>> server1.agama.com

which has my correct ns1. but then if i use nslookup on google.com again with the changed resolv.conf file nothing happens:

Server: 192.168.1.4
Address: 192.168.1.4#53

** server can't find google.com: NXDOMAIN


any ideas on what could be going on? cheers.

Ok so after spending 8 hours reading around the net and this forum. I have put my ISP's nameservers ip addresses in my resolv.conf and removed 192.168.1.1 (my gateway ip).

resolv.conf
search agama.com
nameserver 203.109.129.67
nameserver 203.109.129.68


When I use "dig @localhost ns agama.com" i get:

; (2 servers found)
;; global options: printcmd

which is correct, but if i go "dig `hostname`" i get:

and when i nslookup google.com i get:

Server: 203.109.129.67

Name: google.com
Address: 209.85.171.100
Name: google.com
Address: 74.125.67.100


which is ok

"ns1.gldn.com" is deffinatly the nameservers of the actual domain name ww.agama.com which is not associated to me at all. how do i get this to display my own nameservers e.g "ns1.agama.com" if i use 1.92.168.1.4(server ip) in my resolv.conf file it will work but then i cannot nslookup anything.

Any advice or just to ignore this would be a bit help

thank you.

You must tell your registrar that you want to use ns1.agama.com and ns2.agama.com for the agama.com domain. You will also have to create a glue record: http://en.wikipedia.org/wiki/Domain_Name_System#Circular_dependencies_and_glue_ records

[chipsafts]

are you looking at setting up a seperate internal and external
dns zones setup?

[ggohdin]

Hey, I am pretty confused. I just want it so people can view websites off my server. I know i had a dns problem but I have configured my DNS and hopefully this looks right

when I "dig @localhost agama.co.nz" which will be the website address, i get:

; <<>> DiG 9.5.1-P1 <<>> @localhost agama.co.nz
; (2 servers found)

(ip 123.123.123.123 is just untill my isp sets up my static ip)

when i nslookup google.com i get:
Server: 203.109.129.67
Address: 203.109.129.67#53

Non-authoritative answer:

which is right.

but when I dig "dig `hostname`" i still get:
; <<>> DiG 9.5.1-P1 <<>> server1.agama.com

Is this a DNS glue problem? I know that ns1.gldn.net is owned by a webhosting company that hosts the web address "www.agama.com".

how can I get my server name to stop been confused with agama.com?

also eventually I want to get my server (192.168.1.4) accessible from other computers not on this lan, could they just type my wan ip address with :8080?

netstat -tap if it helps

I have been going on 4 days straight, wondering whats happening, maybe I will reinstall and change my hostname.

[Flash]

You need to change the SOA record of your domain. the name server that is displayed is in that record.

agama.com. 10800 IN SOA ns1.gldn.net. dnsmaster.gldn.net. 2005122700 10800 3600 3600000 86400

Also dnsmaster.gldn.net which is the email adres dnsmaster@gldn.net should probably replaced by something you use.

IF this is a hosted domain by a hosting company, ns1.gldn.net might actually be their name server which is coming from their config. and you might not be able to change that.

[ggohdin]

Hi, I changed the hostname to "newt72.net" when I dig `hostname` now, I get this:

those are not my zones, how do I change zones for hostname?

cheers

[Flash]

A few questions.

1. is newt72.net your domain (eg. did you register that domain) ?
2. are you running a local DNS server with the domain newt72.net in a zone?
3. if 1 or 2 is yes, do you have a entry in the DNS zone for server1 ?

[ggohdin]

Hi, thanks for gettign back to me, I think I have gottect really confused. My hostname for my server is server1 when I type dig `hostname` it resolves to my servers domain (newt72.net), but it doesnt show any of the nameservers it just comes up with the zone for .net.

but I can ping server1 and newt72.net.

If I type " dig @localhost ns newt72.net" everything resolves perfectly.

so im not to sure what I have done.

But If i change my resolv.conf nameserver to my servers ip "192.168.1.4", then when i use dig `hostname` it works, but I know that that ip address connot be there.

[falko]

Have you tried www.intodns.com to find out what's wrong?

[Flash]

dig actually uses your /etc/hosts file if im correct to query first. you might have an entry there for that name.

[ggohdin]

Hey, thanks for the reply. I checked that and that name links to the internal IP of my server, so that shouldent be a problem where when I dig hostname it should get newt72.net at ip 192.168.1.4 then bring up the server info.

am I right?

[falko]

I tried www.intodns.com with newt72.net, and I get "Can't get nameservers at parent server!<br>I only check domains not subdomains!"

Is newt72.net a registered domain?

[ggohdin]

Hi, i think i confused myself as well as you, lol. Ill try some stuff this week and see what happens and ill post back with my findings. Mail server part of the server works though as well as ftp (local only so far).
