1502194 - Please update DNS records for KMS03 in MDC2

Status: RESOLVED FIXED

(Infrastructure & Operations :: Infrastructure: Tools, task)

Description

[Mark Cornmesser [:markco]]

For kms03.ad.db.mdc2.mozilla.com we need an A record pointed to kms03.ad.mozilla.com and the _vlmcs._tcp srv record pointed to kms03.ad.mozilla.com. Currently the _vlmcs._tcp pointed to an old server that was in scl3. 

C:\windows\system32>nslookup -type=srv _vlmcs._tcp
Server:  infoblox1.private.mdc2.mozilla.com
Address:  10.50.75.120

_vlmcs._tcp.mozilla.com SRV service location:
          priority       = 0
          weight         = 0
          port           = 1688
          svr hostname   = kms1.ad.mozilla.com

This should have the same records set up that kms02.ad.mozilla.com has in mdc1.

[Q]

This isn't quite correct we do not strictly need the srv record to point to the ad address.

We do need srv records in the sub domains that any of the mdc2 windows clients might use as a native suffix ( wintest, private, mdc2, etc)  to point to kms03 either to the ad.db or ad A record.

Can you please provide the exact records you need created and I'll get them made asap?

Comment 3

[Mark Cornmesser [:markco]]

Q: should that then be repeated in MDC1 as well? From what I can tell there is only the ad address record for  _vlmcs._tcp ?

Comment 4

[Mark Cornmesser [:markco]]

Could we start with the  _vlmcs._tcp srv record for kms03.ad.mozilla.com in MDC2?

Please get me the exact record you need and I'll make it

In MDC2:
service._proto.name = _vlmcs._tcp
priority            = 0
weight              = 0
port                = 1688
svr hostname        = kms03.ad.mozilla.com

What other info is needed for the record?

Comment 7

[Rob Tucker [:rtucker]]

I need the FQDN of the record to be made, here is an example of an entire record where _kerberos._tcp.dc._msdcs.ad.mozilla.com is the FQDN:

_kerberos._tcp.dc._msdcs.ad.mozilla.com. 600 IN SRV 0 100 88 dc11.ad.mozilla.com.

Comment 8

[Rob Tucker [:rtucker]]

I dug through some previous entries I've created for Q and my best guess is that you need the following record:

_vlmcs._tcp.mdc2.mozilla.com. 60 IN     SRV     0 0 1688 kms03.ad.mozilla.com.

[Rob Tucker [:rtucker]]

:markco,
Please confirm the record mentioned in comment #8 is what you need.

Thanks

Comment 10

[Mark Cornmesser [:markco]]

I think that is what we want.

Comment 11

[Rob Tucker [:rtucker]]

dig srv _vlmcs._tcp.mdc2.mozilla.com @10.48.75.120
_vlmcs._tcp.mdc2.mozilla.com. 60 IN     SRV     0 0 1688 kms03.ad.mozilla.com

Is this good to go?
