Hello something new to test ddclient for ns8, the software to update your dynamic IP to a provider
add-module ghcr.io/stephdl/ddclient:1.0.0-dev.3
you have to read the documentation to find the right protocol and the fqdn server of the api. obviously you need also an account to the provider dynamic dns provider
personally I use dynu.com
we could think to add more control
great new addition, this simplifies even more local hosting, for those without a proper firewall
So far its main task is working but secondary tasks fail (clone, backup…). Few more notes follow.
Didn’t made any field validation tests or forcefully setting wrong values to break things.
DDNS Provider - advice
On the ddns provider side it is reporting what they call “client faults”:
After configuring a new update client, please keep an eye one the Faults column on the overview page. It shows 2 values: C: S:
An increasing number of client faults usually means you (or the software you use) are doing something wrong (e.g. sending updates although your IP address did not change). If you see that, please fix it!
Currently the “client faults” are increasing with every check request. With other ddns names on the same provider using ns7 ddclient module they are shown with no “faults”.
Log Excerpts
Log shows some errors/warnings.
This one about cgroups is probably nothing (services restarting):

Possible features:
Also fine for me if stays as is and give less work.
No multiple ddns providers on a single instance (I think the ns7 module had it) but shall be possible to create another instance.
Backup
Failed, related to mariadb which the app is not using (maybe some remnant code of template used to build the app). Tested on unclean machine, so there’s a chance the problem lays on my side.

good idea, curl can help me I think
yes this is what I could have in mind, I need to create a template system smarter I think, good idea
yes I could think on it, but honestly you will have always a new guy asking to prefill a new provider every time, this is why I implemented the custom mode 
well it could be handy like you stated for sure
I was lazy this wk but for this yes I need a smart template system like jinja, and also a different way to store the information, probably a json file on the disk we could think, or state, install a new instance, the place on the disk is about 90MB
82M /home/ddclient17/
8.3M /var/lib/nethserver/cluster/ui/apps/ddclient17
oups, I missed this, thank
this is relied on the missing IPV6 on your testing server, I could bring a control to enable or disable the ipv6 update to the provider
thank a lot mark for your inputs
add-module Package ddclient · GitHub
backup and clone should be fixed
json validator for the UI
more controls in advanced section
retrieve external ipv6/ipv4 address
add-module ghcr.io/stephdl/ddclient:1.0.0-dev.3
for now still one provider per module 
All working (backup, restore, clone, show ip, check interval, avoid IP change request if IP has not changed…)
Minor thing: I think the “ddclient webapp” status card can be removed (no virtual host to set / no related webapp). Otherwise it’ll always state “Not configured” which could be misleading on the meaning.
thank @dnutan, it is released with your last fix
