DNS issues SERVFAIL - jemmrich - 12-01-2008 11:02 PM

Hi everyone,

For some reason i cannot access any of the domains on my server. And the times that I am able to access them, i am starting to think that it is because my ISP has cached the DNS records. I haven't changed any of the DNS information on the domains so everything should be working, unless something has changed when i upgraded from vhcs2 a few days ago.

I get this when i enter: "dig lwp.ca" on the command line
Code:
james@mobilewolf:~$ dig lwp.ca
; <<>> DiG 9.4.2-P2 <<>> lwp.ca
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 41824
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

And here is my bind config for this domain: /var/cache/bind/lwp.ca.db

Code:

Is there anything i can do to figure out why this isnt working?

Here are a couple more domains hosted on the same server: motocrosscanada.ca comandracing.com mcxtreme.com

Thanks for any help,
James

I get the right answer with dig - your IP.

But also a "dig @66.203.160.5 lwp.ca" prints the right answer.

One thing:
the nameservers are: ns3.bellglobal.com and ns1.motocrosscanada.ca but only the first one is valid (has an IP adress...) the second cannot be resolved.

Hope this helps...

Hi, I just got new secondary dns server just now. which will be valid.

The ip 66.203.160.5 is my ISPs dns server i believe, and i think it caches dns requests so it works even when things don't for others--makes it really hard to figure out where the root of the problem is.

Also, i noticed that ispcp sets up ns1 and ns2 in the zone files. Should i be using these as the primary name servers? VHCS2 i believe just called them ns without numbers, if so i will have to update all my domains primary name servers to ns1.domain.tld .

One thing also, is that walton.compar.com always works even during these times of weirdness and is the only domain i can use to ssh into my server with during these times.

Thanks,
James
