Mailinabox: secondary nameserver with multiple addresses breaks secondary check and status screen

[steadfasterX]

MIAB v0.28 (yea i have to update - but thats not the issue here ..)

Follow up to (the unsolved closed): #666

The same issue catched me today while it took me a while to find the root cause:

I have configured the (free! and DNSSEC supporting!) secondary DNS service of www.1984.is and defined "ns2.1984.is" as my secondary NS in MIAB.

The zones get transferred correctly (after setting the correct xfr ..) but the status screen of MIAB broke after I added all domains at 1984.is.
It breaks just with a "Something went wrong, sorry" which is defined in the default_error (click) function (yea the _default_error_ one - not the other).
So I moved on and started the status_check.py from the cmdline and it states on all "ns2.1984.is" secondary queries a [timeout] (click). _dig_ and _nslookup_ on "ns2.1984.is" answered both very quickly though.

I adjusted the timeout but that was not the reason so I played a bit with the code and printed the content of the "[at]" (click) list which prints the 2 (two!) IP's of "ns2.1984.is" separated by a ";" .
So I dived deeper and found that when I hard-code one of these IP's to that list (I replaced [at] with ["93.95.226.52"]).. it just works without an issue. Status Screen displays fine again and ofc no timeouts or error messages anymore.

So I guess multiple A records of a secondary NS server is causing that issue.

So I guess multiple A records of a secondary NS server is causing that issue.

• As per your words you did it wrong as you don't need to create/ add A records for that...

The place where you need to add the additional (sub)domains given by the DNS slave service providers is at the Using a secondary nameserver section inside hostname field. As an example, mine are:

ns2.1984hosting.com ns6.gandi.net puck.nether.net xfr:93.95.224.6 xfr:204.42.254.5

• Where the first is one from 1984.is, the second one is the one given by my domain registar provider, the third the one by puck.nether,net and finally the two XFR from 1984.is and puck.nether

Hope this helps.

I haven't created any A records here. Just resolve ns2.1984.is by yourself and you will see you get 2 A records for that fqdn. That's set by them not by me.

Sounds good. congrats!
