18 When executed the DHIS server reads its client's database (by default from
19 -/etc/dhis/db/dhis.db) into memory and proceeds to listening mode on a UDP
20 -port (by default 58800). When messages arrive the server responds accordingly,
21 -authenticates the clients (based on the keys and information loaded from the
22 -database) and marks them online. Furthermore the server keeps sending periodic
23 -checks to each and every client in order to verify that these are still
24 -connected. If a particular client fails to reply the server will consider it
25 -offline and mark it accordingly.
