389ds and dual stack IPV4/6

[N R]

Hello all,

It's my first message on this list thanks in advance for your answers.

I've configured a 389ds instance with ipv6 address and it's working
great with it.
I need for this instance to be reachable via ipv4 also but despite
hours of research on the web and the archive of the list, I couldn't
find any good help or how-to to setup 389ds to listen on both ipv4 and
ipv6 addresses.
I can't find a parameter specifying the listening interfaces.

Has anyone faced this kind of setup and managed to make it work?
Can 389ds work this way?

Best regards,

[Mark Reynolds]

The server listens on all interfaces, there is nothing special you need 
to do in DS for IPv6 or IPv4.  I'm not a network expert, but it would 
seem to be a system issue, not a DS issue.  Now, we do have 
nsslapd-listenhost, so it would be interesting to see if this has any 
impact on your situation:

Maybe someone else on this list has seen this before?

How did you configure the instance exactly?

What do you have for nsslapd-localhost in the cn=config entry(dse.ldif)?

It should be a hostname, not an IP.  And the hostname must correctly 
resolve to this system.  DS is very sensitive to the hostame/dns - it 
very important for things like TLS and replication.

Hi Mark,

Thanks for your replies.
> How did you configure the instance exactly?

The host is a Fedora 30 VM, I installed 389ds using the package
manager (dnf) and the setup-ds-admin.pl script.
I enabled LDAPS over TLS on the standard port (636).
The VM has a single network interface with both ipv4 and ipv6 address on it.
There is no DNS service on the network so I'm using /etc/hosts to
associate the hostname with IPs.
The hostname is annuaire.telerys.infra

nsslapd-localhost: annuaire.telerys.infra
> nsslapd-listenhost, so it would be interesting to see if this has any
> impact on your situation:

I've tried several things with this parameter and had strange results
with netstat -tunlp (snippet below only show lines relative to slapd):

nsslapd-listenhost: annuaire.telerys.infra
tcp6       0      0 [IPV6 address]:389 :::*                    LISTEN
    1208/ns-slapd
tcp6       0      0 ::1:389                 :::*
LISTEN      1208/ns-slapd
tcp6       0      0 :::636                  :::*
LISTEN      1208/ns-slapd

nsslapd-listenhost: [IPV4 address]
tcp        0      0 [IPV4 address]:389       0.0.0.0:*
LISTEN      1136/ns-slapd
tcp6       0      0 :::636                  :::*
LISTEN      1136/ns-slapd

nsslapd-listenhost: [IPV6 address]
tcp6       0      0 [IPV6 address]:389 :::*                    LISTEN
    1285/ns-slapd
tcp6       0      0 :::636                  :::*
LISTEN      1285/ns-slapd

Why is the service always listening for IPV6 on port 636 whatever the
parameter is set to?

I've been able to find what was wrong in my configuration, I had a
typo in the /etc/hosts file.

Thank you a lot for your time and your precious advices.

Can I ask what the typo was? I'm curious how that caused this to listen on v6 only? What was the setting of your securelisthost value in cn=config?

389ds and dual stack IPV4/6, also...

[N R]

Hi Williman,

I mistyped the hostname of my computer, the ipv4 was associated with
"annuaire.telerys.inTra" instead of "annuaire.telerys.inFra" so
really, basic typo.
That explains also why only ipv6 was properly handled.

Besides that, I've assigned the same hostname "annuaire.telerys.infra"
to both "cn=config" parameters mentioned by Mark :
nsslapd-listenhost: annuaire.telerys.infra
nsslapd-securelistenhost: annuaire.telerys.infra

Beswt regards,
Nick Rand
