Install instructions for DHIS R5 server module dhis-dns-engine
==============================================================

This package contains a dynamic DNS service module to be used
with dhisd release 5 or above.

While the DHIS server dhisd retrieves dynamic IP addresses
from clients, this module allows the server to update a
dynamic DNS zone based on those retrieved IP addresses.

This module uses the DHIS server database file itself to build
its ID to FQDN matrix. When reading /etc/dhis/db/dhis.db 
it ignores all keyword lines apart from HostName. 

This allows a single database file for both DHIS plus DNS module.
The DHIS server likewise ignores HostName lines. 

Database files from release 4 may be used with DHIS R5 + this module

In order versions, this module issued nsupdates directly and required to
be linked with the bind libraries. Furthermore it only supported some
BIND 8 versions. 

As of the 5.1 version of this module, any BIND versions with a valid
nsupdate binary command can be used (including 9). This module simply formats the 
commands and issues them to the system's nsupdate binary 
(tipically /usr/sbin/nsupdate). 

For more information on modules see the dhisd documentation.
