DNS problem

I have a VPS freshly set up using: The Perfect Server - Ubuntu 12.04 LTS (nginx, BIND, Dovecot, ISPConfig 3)

So far I am still trying to figure out how to get rid of the error:

root@server:/etc/bind# ls

Code:

bind.keys  db.empty    named.conf.default-zones     rndc.key
db.0       db.local    named.conf.local             slave
db.127     db.root     named.conf.options           zones.rfc1918
db.255     named.conf  pri.ns1.example.com.err

the contents of the error file:

Code:

$TTL        3600
@       IN      SOA     ns1.example.com. mail.example.com. (
                        2013062812       ; serial, todays date + todays serial #
                        7200              ; refresh, seconds
                        540              ; retry, seconds
                        604800              ; expire, seconds
                        86400 )            ; minimum, seconds
;

example.com. 3600      MX    10   mail.example.com.
example.com. 3600      NS        ns1.example.com.

ns2 86400 A        173.333.222.105
www 3600 A        173.333.222.105

I also tried this

Code:

root@server:/# dig @localhost example.com

; <<>> DiG 9.8.1-P1 <<>> @localhost example.com
; (1 server found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 54614
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; WHEN: Fri Jun 28 22:41:11 2013
;; MSG SIZE  rcvd: 33

And

Code:

root@server:/# dig @localhost ns1.example.com

; <<>> DiG 9.8.1-P1 <<>> @localhost ns1.example.com
; (1 server found)
;; global options: +cmd
;; Got answer:

;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Fri Jun 28 22:44:56 2013
;; MSG SIZE  rcvd: 37

I checked /var/log/syslog and it is empty.

I can access the site via the ip address but when I point the browser to example.com I get "server not found" (on Firefox) and "This webpage is not available" (on chrome).


Any help with resolving this issue is appreciated.

 

Here is snapshots from ispconfig panel

 

still no luck

domain has yet to be resolved. Any ideas from the community wold be very helpful! any1?

 

There are many log files as shown below

Code:

root@server:/var/log# ls
alternatives.log    dmesg.0                lastlog         nginx
alternatives.log.1  dmesg.1.gz             mail.*          ntpstats

dmesg               kern.log.1             news

I looked at syslog and it was empty, what log file I am to look at?
Thanks

 

Anyone with knowledge in ispconfig out there to try help me out here??

 

Do you have the server that bind is running on set up as a dns server in your /etc/network/interface flie ?

auto eth0
iface eth0 inet static
address 173.333.222.105
netmask 255.255.255.0
network X.X.X.X
broadcast 173.333.222.255
gateway X.X.X.X
dns-nameservers 127.0.0.1 8.8.8.8 8.8.4.4

If you dont have 127.0.0.1 added, bind will only look up the external dns servers (eg: 8.8.8.8 and 8.8.4.4 in above case. ) to get an IP address and act as a dns cache. So any local records will not be looked up.

check /etc/resolv.conf and see what the nameserver settings are.

 

Thanks for the reply. I am certain that you pin pointed where the problem is, but so far I couldn't correct it.

So here is what I found: by running nano /etc/network/interfaces I got

Code:

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
    address 173.333.222.105
    gateway 173.333.222.97
    netmask 255.255.255.240

and by running nano /etc/resolv.conf I got:

Code:

nameserver 208.xx.xxx.170
nameserver 64.xx.xx.2

where did these name servers ips come from?

anyway I changed my network/interface to:

Code:

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
    address 173.333.222.105
    gateway 173.333.222.97
    netmask 255.255.255.240
    network 173.333.222.0
   boradcast 173.333.222.255

   dns-nameservers 127.0.0.1 208.xx.xxx.170 64.xx.xx.2

then restarted networking /etc/init.d/networking restart
but still site is not resolved yet!

could you plz point out what I am doing wrong ??

Thanks again

 

What are those dns server you have listed, are they for your local isp? For testing you may want to use the 8.8.8.8 and 8.8.4.4 (those are google dns).

Can you post your server config Dns tab?

In Sever config, make sure to set your gateway even though I doubt it'll make a big difference.

Also, when you say you cannot resolv the website, are you testing inside the network or from the outside? (makes a big difference).

 

also pleas post your bind config and specifically what is the parameter for listen-on.

 

Here is my Server Config tab


The snapshot was taken before I set the gateway to 173.333.222.97 (didn't make a difference).

I rechecked /etc/resolv.conf and now it shows this:

Code:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.0.1

my /etc/network/interfaces looks like:

Code:

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
    address 173.333.222.105
    gateway 173.333.222.97
    netmask 255.255.255.240
    network 173.224.222.0
   boradcast 173.224.222.255
   dns-nameservers 127.0.0.1 8.8.8.8 8.8.4.4

I am testing from outside the network. ip address resolves, but not www.site.com

 

Code:

options {
        directory "/var/cache/bind";

        // If there is a firewall between you and nameservers you want
        // to talk to, you may need to fix the firewall to allow multiple
        // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.

        // forwarders {
        //      0.0.0.0;
        // };

        //========================================================================
        // If BIND logs error messages about the root key being expired,
        // you will need to update your keys.  See https://www.isc.org/bind-keys
        //========================================================================
        dnssec-validation auto;

        auth-nxdomain no;    # conform to RFC1035
        listen-on-v6 { any; };
};

/etc/bind/named.conf.local is empty file

 

I looked at syslog file and it is blank (0 lines)

 

Yes.

Could you look into my server and ispconfig setting? I could pm you my server info.


Thanks

 

Just to make sure, you have ns1.example.com registered with a glue record at your name register right?

Also, please post your server config->DNS tab.

 

Yes my name servers ns1 and ns2 are registered with a glue record (used them
before ispconfig on kloxo and worked)

here is my dns server config




Thanks

 

what's your output of:

/etc/init.d/rsyslog status

?
