Re: [Freeipa-users] Dynamic DNS Questions

2016-06-08 Thread Detlev Habicht 
Thank you, this is it.

This entry was already in sssd.conf (with the wrong interface). But i was 
looking for an
IP number … Ignoring interfaces. Stupid, my fault.

Thank you again

Detlev

Re: [Freeipa-users] Dynamic DNS Questions

2016-06-08 Thread Martin Štefany 

Hello Detlev,

FreeIPA/SSSD client use IP address of interface/vlan/subnet which is use 
to communicate (LDAP) with FreeIPA server.


However, if you have dyndns_update set to True in sssd.conf, you can 
also set dyndns_iface to point to correct interface which IP addresses 
will be dynamically updated in DNS, see:


$ man sssd-ipa
[stripped]
   dyndns_iface (string)
   Optional. Applicable only when dyndns_update is true. Choose 
the interface or a list of interfaces whose IP addresses should be used 
for dynamic DNS updates. Special value “*” implies that IPs from all 
interfaces

   should be used.

   NOTE: While it is still possible to use the old 
ipa_dyndns_iface option, users should migrate to using dyndns_iface in 
their config file.


   Default: Use the IP addresses of the interface which is used 
for IPA LDAP connection


   Example: dyndns_iface = em1, vnet1, vnet2
[stripped]

Kind regards,
Martin

Hi all,

well, i am really a beginner with IPA and just trying to setup some
test systems. In the moment one IPA server, one NFS/Samba server and a
fedora CLient. I am running IPA 4.2, Scientific Linux 7.2 and Fedora 23.

The most important things are running now.

But i have a problem with DNS entries left. Maybe while installing
IPA i make mistakes with the NFS Server. On this NFS server i have 5
interfaces. 4
of them now as bond interface. So i am running two IPs now: nn.16 and
nn.33.

But while installing IPA (with DNS) it takes the wrong one (16):

2016-05-26T14:08:12Z DEBUG Writing nsupdate commands to

I can change the DNS entry on the IPA server to nn.33 at runtime. Then
everything
is ok. But when i boot the NFS server, it is changing the DNS entry on
the IPA Server to nn.16.

What can i do so the IPA client (here my NFS Server) is using the right IP?
I don’t find any conf-File … Is there any point where i can change this IP?

Thanx for any help!

Hello,

DNS updates are done by sssd daemon on the client, you may want to 
disable dynamic updates or set interfaces which should be used


man sssd-ipa  find for dyndns_update and dyndns_iface
