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

At the time of writting this module supports BIND versions from
8.1.2 to 8.2.3. BIND 9 is not yet supported. Versions lower than 
BIND 8.2.3 have been found subject to possible exploits. Therefore
the recommended version of BIND to use with is module is 8.2.3.
For versions lower or equal than 8.2.1 please uncomment -DBIND821
in the Makefile.

For more information on modules see the dhisd documentation.
