I've got the ebox appliance with version 1.4
Dynamic update of DNS via DHCP daemon does not work.
The message in /var/log/syslog is
Apr 13 11:29:00 ebox dhcpd: Added new forward map from mbwfrank.corp.flowgistics.de. to 10.0.1.49
Apr 13 11:29:00 ebox dhcpd: unable to add reverse map from 49.1.0.10.in-addr.arpa. to mbwfrank.corp.flowgistics.de.: timed out

Hi Frank,
Apr 13 11:29:00 ebox dhcpd: Added new forward map from mbwfrank.corp.flowgistics.de. to 10.0.1.49
Apr 13 11:29:00 ebox dhcpd: unable to add reverse map from 49.1.0.10.in-addr.arpa. to mbwfrank.corp.flowgistics.de.: timed out
As the log says the forward map is working but the reverse map (IP -> name) does not work as current limitation of our implementation. [1]
Cheers,

Is there any workaround that be implemented to fix this, for example, by modifying the stub files.
Can you provide any technical information on why Zentyal is unable to update the reverse records?
Regards
Andrew

Welcome to the forums Andrew,
You realise you replied on a 2year+ old topic?
Do you have a 'similar' problem? then please open a new topic, since this is about a VERY old version, based on Ubuntu 8.04

Hi Robb,
Thanks for your quick reply!
Yes, I realised it was old, but I have [nearly] the exact same symptoms. I'm using Ubuntu 12.04 and Zentyal 2.3:
Aug 23 16:47:28 zentyal named[19327]: client 127.0.0.1#41489: updating zone 'tld.com/IN': update unsuccessful: andrew-desire-z.tld.com: 'name not in use' prerequisite not satisfied (YXDOMAIN)
Aug 23 16:47:28 zentyal named[19327]: client 127.0.0.1#55682: updating zone 'tld.com/IN': deleting rrset at 'andrew-desire-z.tld.com' A
Aug 23 16:47:28 zentyal named[19327]: client 127.0.0.1#55682: updating zone 'tld.com/IN': adding an RR at 'andrew-desire-z.tld.com' A
Aug 23 16:47:28 zentyal dhcpd: Added new forward map from andrew-desire-z.tld.com. to 192.168.1.50
Aug 23 16:47:28 zentyal dhcpd: unable to add reverse map from 50.1.168.192.1.168.192.in-addr.arpa. to andrew-desire-z.tld.com.: timed out
I have replaced our actual domain name with tld.com
Regards
Andrew

That last line might throw you out a bit, I had been testing some workarounds that I found on Google. I removed them, went back to the Zentyal DHCP settings and double-checked that DDNS is enabled, the output now is different:
Aug 23 17:12:06 zentyal named[47482]: client 127.0.0.1#39258: updating zone 'tld.com/IN': adding an RR at 'andrew-imac.tld.com' A

Aug 23 17:12:06 zentyal dhcpd: Added new forward map from andrew-imac.tld.com. to 192.168.1.20
Aug 23 17:12:06 zentyal dhcpd: unable to add reverse map from 20.1.168.192.in-addr.arpa. to andrew-imac.tld.com.: timed out
