787681 - preproduction-master cannot resolve hosts in mtv

Status: RESOLVED FIXED

Description

[Chris Cooper [:coop] (he/him)]

preproduction-master (scl3) cannot resolve hosts in mtv. I think this is preventing it from talking to certain classes of hosts that exist solely in mtv, e.g. the darwin10 builders. This problem may be limited to doing reverse lookups.

[cltbld@preproduction-master ~]$ host moz2-darwin10-slave02.build.mozilla.org
moz2-darwin10-slave02.build.mozilla.org is an alias for moz2-darwin10-slave02.build.mtv1.mozilla.com.
moz2-darwin10-slave02.build.mtv1.mozilla.com has address 10.250.48.222

[cltbld@preproduction-master ~]$ host 10.250.48.222
Host 222.48.250.10.in-addr.arpa. not found: 3(NXDOMAIN)

[cltbld@preproduction-master ~]$ cat /etc/resolv.conf

search srv.releng.scl3.mozilla.com
nameserver 10.26.75.40
nameserver 10.26.75.41

It looks like the releng scl3 name servers are missing the reverse zones for 10.250.48 et.al.

Our data centers have reverse DNS access for other data centers, offices were the only exception to this except for the mpt-dmz view. I've added zones.mvoffice-reverse to the other data center views.

Using domain server:
Name: 10.26.75.40
Address: 10.26.75.40#53
