Description Felix Botner

2015-10-20 13:43:52 CEST

Installed a 4.1 UCS master as AD member. In AD my UCS system now has 3 host records!?

nslookup ucs-1386
Server:         10.200.7.132
Address:        10.200.7.132#53

Name:   ucs-1386.w2k12.test
Address: 10.200.7.189
Name:   ucs-1386.w2k12.test
Address: 10.200.7.188
Name:   ucs-1386.w2k12.test
Address: 172.17.42.1

172.17.42.1 -> docker0
10.200.7.188 -> ip during system setup
10.200.7.189 -> this is the actual ip of my master

ucs-1386 -> hostname of my master
10.200.7.132 -> ip of the ADS

I guess univention-samba.postinst also needs to

  ucr set samba/register/exclude/interfaces='docker0'

like in univention-samba4.

Comment 2 Felix Botner

univention-samba 

 * sets samba/register/exclude/interfaces?docker0 as default
 * 01univention-samba_main ignores all interfaces from 
   samba/register/exclude/interfaces:
   * get list if all interfaces,
   * remove all samba/register/exclude/interfaces from interfaces
   * remove appliance-mode-temporary interface from interfaces
     (interfaces/IFACE/type=='appliance-mode-temporary')
   * set bind interfaces only = yes
   * set interfaces = interfaces
 * 01univention-samba_main ignores samba/register/exclude/interfaces
   if samba/interfaces/bindonly is set

YAML: univention-samba.yaml

Comment 3 Stefan Gohmann

Test: YAML: OK

Test: docker0 set by default: OK

Test: samba/register/exclude/interfaces can be set to eth0 and to ethFoo: Fail

root@ucs-6611:~# ucr set samba/register/exclude/interfaces='docker0 eth0 ethFoo' 
Setting samba/register/exclude/interfaces
Multifile: /etc/samba/smb.conf
Traceback (most recent call last):
  File "<stdin>", line 41, in <module>
ValueError: list.remove(x): x not in list
root@ucs-6611:~# 

Can you add a simply check?

Test: lo is still in the list of the interfaces: OK

Test: samba/interfaces/bindonly is preferred: OK

Test: docker0 interface is not registered by default: OK

fixed

(In reply to Felix Botner from comment #4)
> fixed

OK, works now:
root@ucs-6611:~# ucr set samba/register/exclude/interfaces='docker0 ethFoo' 
Setting samba/register/exclude/interfaces
Multifile: /etc/samba/smb.conf
root@ucs-6611:~# grep 'interfaces =' /etc/samba/smb.conf
        interfaces = lo eth0
root@ucs-6611:~#
