Hello…

I have three nameservers on my system… wtsa-ubuntu-main.workbooksonline.com, ns1.workbooksonline.com and ns2.workbooksonline.com The ns1 & ns2 were created after I had a better idea what I was doing with these type of servers and the wtsa was created by the system when I originally installed it.

When I go to intodns.com it tells me I have a problem because the wtsa-ubuntu-main.workbooksonline.com address doesn’t resolve properly. The wtsa-ubuntu-main.workbooksonline.com is also the SOA for my system. So I was thinking I need to change the SOA so that it matches my ns1.workbooksonline.com so that all my nameservers actually resolve. I this something I should be considering… or is it just unnecessary and I should accept the error?

How hard is it to change the SOA? Will it disrupt all the virtual domains? For future installations should I change this right away before creating the virtual domains? Should I change it on the server templates for future virtual domains I create?

Also… another error I’m getting is that all three of the nameservers are on the same server and same IP address creating a single point of failure for the nameservers. Should I somehow split this between a couple of machines on different IP addresses to ensure multiple points of failure? If so, how should I do that.

Thanks in advance for your advice!

Always learning!!!

@danwtsa,

Just create an A record for “wtsa-ubuntu-main.workbooksonline.com”

Hello…

I already have an A record for “wtsa-ubuntu-main.workbooksonline.com” but inspite of that intodns.com still keeps coming back and telling me it’s an error.

In System Settings > Server Templates > Default Settings > Edit Server Template > DNS Domain

  1. Is the hostname specified for Master DNS server hostname, and
  2. Are the additional nameservers listed in the box labeled Additional manually configured nameservers ?

As for SOA serial, I’m pretty sure it should auto-increment when you edit the file. If not, add 1 to it, save, and restart BIND.

You have a good suggestion and it works for the new websites. But it doesn’t change anything for the existing websites that I can see. The master DNS server hostname stays the same for the websites previously created.

Is there a way to change the master DNS server hostname for the entire installation?

@danwtsa,

For template changes to take effect on existing domains, simply disable that feature then re-enable it.

BEWARE doing the above means any custom entries will need to be recreated afterwards.
