The initial question however is still unsolved: why does
ipa-replica-prepare behaves differently on fedora and rhel? I thought,
rhel host had more than one reverse zone, but it's not the case.

Not sure why the difference but you can pass --no-host-dns to
ipa-replica-install, it should skip the reverse zone check.
We may want to add a ticket to make the reverse check just a warning,
installation should not fail, but the default is to stop in unattended
mode unfortunately.

OK, so, I can temporarily add this hack and create a separate ticket requesting to turn an error into a warning if reverse address resolution fails during replica installation, right? The problem is that this issue blocks execution of integration tests in RHEL, which is one of the top-priority tasks for Downstream QE team


Can you try fedora on the same machine?

Are you sure that both systems has the same configuration. E.g. one
could have only IPv4 but the other also IPv6?

Hi Martin,

I guess, I know where is the problem. During replica-install the
replica tries to resolve it's own ip to a hostname to check whether
the dns is configured correctly. And fails, since we specified
--no-reverse during the replica preparation on master.
This looks like a bug to me.

Why is that a bug? Where should ipa-replica-prepare put a SRV record if
no reverse zone is created?

SRV records are not stored in the reverse zone, we should work just fine
w/o a reverse zone.

I.e. if I do not want to add them by ipa-replica-prepare e.g. because
they are not managed in IPA then they have to be added to DNS
server(whatever server it is) by other means.

We *should* be able to work fine w/o reverse zones or with reverse zones
that point to bogus names.
I think this is something we SHOULD test because it is a normal network
condition in some organizations (because they can't control reverse).
If something fails if reverse is wrong/missing we need to fix it,
because relying on reverse resolution is broken (vs security) anyway and
we should not.

Simo.

Hi all,

I am trying to run integration tests for dnssec in RHEL-7.2
The tests keep failing at the step of preparing the replica. I
figured
out, the ipa-replica-prepare with the standard parameters
requests
reverse zone info (does not do it in fedora) which causes the
test to
fail.

Does anyone know why does it do it? We can, of course update our
tests
adding a --no-reverse option, but I'd like to know how come it
behaves
differently depending on the platform.

The system is
dell-pe1950-06.rhts.eng.brq.redhat.com

The command looks like this:

[root@dell-pe1950-06 ~]# ipa-replica-prepare -p '<password>'
--ip-address 10.34.54.25 dell-pe1950-05.rhts.eng.brq.redhat.com
Do you want to configure the reverse zone? [yes]:

Reverse zone is not needed for DNSSEC test, you can use
--no-reverse
option.

Did you test fedora on the same machine?
No, it's a beaker-provisioned vm.

I added a --no-reverse to the install_replica method in
ipatests/test_integration/tasks.py. It fixed this particular issue.
However, now the test fails at the step of ipa-replica-install:

[root@dell-pe1950-05 ~]# ipa-replica-install -U -p '<password>' -w
'<password>' --ip-address 10.34.54.25
/var/lib/ipa/replica-info-dell-pe1950-05.rhts.eng.brq.redhat.com.gpg

--setup-ca --setup-dns --forwarder 10.34.32.1
WARNING: conflicting time&date synchronization service 'chronyd'

ipa         : ERROR    Unable to resolve the IP address
2620:52:0:2236:215:c5ff:fef3:e54f to a host name, check /etc/hosts
and DNS name resolution


Hmm, this is interesting, is 2620:52:0:2236:215:c5ff:fef3:e54f IP
address of replica or master.


Does the resolv.conf point to master on replica?
It's an ip address of the replica. And yes, it does point to master's
ip.
