testing dyndns_update

[steve]

Hi
We have 1.10.0beta1 on lubuntu 13.04

We have added
dyndns_update=true
dyndns_refresh_interval=1
to sssd.conf

We expect to see an update request after 1 minute, but nothing happens. 
Are we correct to expect this behaviour?

Cheers,
Steve

dyndns_refresh_interval (integer)
           How often should the back end perform periodic DNS update in
           addition to the automatic update performed when the back end
           goes online. This option is optional and applicable only
           when dyndns_update is true.

Default: 86400 (24 hours)

It is not explicitelly written, but you could noticed,
that default value is in seconds. (86400 seconds == 24 hours)

Hi. Thanks. I changed it to:
dyndns_update=true
dyndns_refresh=60

No DNS request is made. We have a Samba4 dc which accepts dns requests 
from the windows clients so it seems to be working. I have set the log 
level to 6 but nothing gets logged. I'm looking in:
/usr/local/var/log/sssd, /var/log/sssd

It's starting OK and getent and user logins work fine, just not the dns 
update requests.

Here is our sssd.conf. What are we missing to be able to trigger the dns 
update requests?

^^^^

Currently the dyndns updates are only supported with id_provider=ad or
id_provider=ipa

Since you're using the POSIX attributes, you'd want to configure a
domain similar to:

id_provider = ad
ad_server = hh16.hh3.site
ad_domain = HH3.SITE
ldap_id_mapping = False
> auth_provider = krb5

Hi
OK. Changed that but then sssd crashes after the first DNS update and no

Hi
sssd seems to be sending the wrong request to the DNS server:

It is querying DNS/[e-mail]
We do not have that spn. Why doesn't it try DNS/[e-mail] 
which we do have?
Thanks
Steve

@Simo Could you confirm that this works against a Samba4 AD?

The logs are telling you that the SSSD cannot resolve the machine's host
name. Can you try overriding it with "ad_hostname" or adding the
hostname to /ec/hosts ?

Where do these errors come from? I suspect this is actually nsupdate,
not sssd. We simply call out nsupdate with GSS-TSIG.

Oof, I suspect we don't handle the situation where we can't get the
machine host name well:
https://fedorahosted.org/sssd/ticket/1913

Can you get us a backtrace, please?

Hi
I added:
ad_hostname = pinoso.hh3.site
to sssd.conf. It was already in /etc/hosts

Now the request is sent and we can see it on the Samba4 DC:

Tkey handshake completed
Got a dns update request.
update count is 1
Looking at record:
      discard_const(update): struct dns_res_rec
         name                     : 'pinoso.hh3.site'

But the IP is not updated. We changed it from 192.168.1.100 to

It is sending the old IP. 101 is the old IP. We changed it to 100, 
restarted the network, removed the cache and restarted sssd:

server hh16.hh3.site
realm HH3.SITE
update delete pinoso.hh3.site. in A
send
update delete pinoso.hh3.site. in AAAA
send
update add pinoso.hh3.site. 3600 in A 192.168.1.101
send

We can only make it get the new IP by rebooting the client. Must we 
reboot each time?
Thanks

Hi
OK. It's working fine, (but the TSIG errors are worrying).

We don't really want to have to restart sssd after a dnydns update, so 
to make your test case at:
  https://fedoraproject.org/wiki/QA:Testcase_sssd_ad_dns_update
a little more realistic, how about:

e.g., using our lan IP's:
Set the test client to static IP 192.168.1.100:
ifconfig eth0 192.168.125.100 netmask 255.255.255.0 up
domain user logs in and logs out

Set the test client to static IP 192.168.1.101:
ifconfig eth0 192.168.125.101 netmask 255.255.255.0 up
domain user logs in

check: the IP of the client has been updated
The database always seems to be contacted upon login, not the cache.

Is this the expected outcome of dyndns_update?

Thanks for your help and a nice utility.

If you restarted the SSSD, then it *should* pick up the new address.

There are two ways a client can learn what IP address to use for
dynamic DNS update:
    1) retrieve the address automatically from the socket that is used
    to connect to the LDAP server. This is the default.
    2) You can set the dyndns_iface option to name of an interface and
    then all addresses from that interface will be used during the
    update.
I presume you are using 1), then without SSSD restart the old address
might still be read from the socket I guess, but since you say you
restarted the sssd, then I would expect it to pick up a new address.

Does this client use DHCP or only static addresses? Any chance the DHCP
server might clobber the new address you set?

Hi
This works:
Start sssd
set the IP
login and out as ad user
change the IP
login again
sssd consults the server and the IP is updated. Perfect!

Works with both static and dhcp IP changes.
I've no idea why but it's good enough for us.

When will the beta go oficially stable? (I'm not allowed beta in 
production).
Cheers,
Steve

Sorry. Only works with static IP changes. What would we do to get it 
working for dhcp too?

Anything easier (automatic even) than:
sudo dhclient -r
sudo dhclient eth0

A little more explanation -- there are two ways the client performs the update:
1) when the back end transitions from "offline" to "online" state
2) Periodically. Currently the dyndns_refresh_interval option defaults
to 86400 seconds (24 hours).

You can simulate the online transition by sending SIGUSR1 to the SSSD to
tell it to go offline, then SIGUSR2 to go back online. See man sssd(8)
for more info on the signals.

Do you know if the client picked the new address from DHCP? (the syslog
would tell I guess). If you need to renew the lease, then maybe it was
still using the old address?

I would say four to six weeks from now (mid to end of June).

Right now, it's really a beta and there are inevitably bugs as the
features and patches are still flowing in.
