Zentyal 6 DHCP update DNS
« on: January 10, 2019, 05:12:52 am »
Hi,

I have selected the DHCP option to update DNS records.

This feature only works for domain machines. Non-domain machines cannot be reached by name, only IP address.

Can anyone help troubleshooting this?

Thanks.

146 read and no answers...
That topic is not solved and is a real pain.
This is a very basic feature of a system like Zentyal, to register DHCP leases into the DNS. If it's broken, you can't claim to have DNS and DHCP sync'ed.
I could setup a DNS with DHCP and get every new leases register to DNS without a problem on Ubuntu 18.04, but Zentyal is using scripts and templates so I could not patch my system. Look like a Kerberos key problem or at least some bad permissions somewhere.

I'm not sure that product is still under developpement, this is a real bug preventing Zentyal to do his work, leaving it totally useless.

Tested with 6.0 (not modded):

The more I dig in theses forum, the more I found that project is totally forgotten.
You got dozen of messages with the same error, DHCP not able to update DNS.
