mesos-dns server is not responding properly to zone NS request (ERROR: mesos-dns.... resolver.go:393: NS request

[cruizpollino]

Good morning everyone

We've installed and configured mesos-dns on server named compute1.mad.roche.com, to act as DNS server for some services running on top of marathon/mesos ecosystem

cat config.json
{
"zk": "zk://centostest61.mad.roche.com:2181,centostest71.mad.roche.com:2181,centostest85.mad.roche.com:2181/mesos",
"refreshSeconds": 60,
"ttl": 60,
"domain": "prhpc.roche.com",
"port": 53,
"timeout": 5,
"email": "root.prhpc.roche.com",
"httpon": true,
"dnson": true,
"httpport": 8123,
"externalon": false,
"listener": "10.120.39.154",
"SOAMname": "root.ns1.prhpc.roche.com",
"SOARname": "ns1.prhpc.roche.com",
"SOARefresh": 60,
"SOARetry": 600,
"SOAExpire": 86400,
"SOAMinttl": 60
}

mesos-dns is answering properly to requests related with services running on mesos

But when we run

• dig @compute1.mad.roche.com prhpc.roche.com NS

We got
# dig @compute1.mad.roche.com prhpc.roche.com NS

; <<>> DiG 9.9.4-RedHat-9.9.4-18.el7 <<>> @compute1.mad.roche.com prhpc.roche.com NS

And in mesos-dns log we got
*ERROR: 2015/10/02 08:15:20 resolver.go:393: NS request

I've tried setting the parameter SOARName to compute1.mad.roche.com, but behavior remains identical

I've read the thread #73, and it looks like this behavior shall be addressed already.

Could any of you guys please help me set the NS resolution properly or confirm me if this behavior is expected one?

Kind Regards

Hello there!

Thanks for reporting. Once #296 is merged I'll cut a release which you'll be able to download. You'll have to switch around the values of SOARname and SOAMname in your config.

PS: Would you mind to follow the guidelines for filing and issue next time? https://github.com/mesosphere/mesos-dns/blob/master/CONTRIBUTING.md#issues
