The system does a 24 Hour Restart to clean out the buffers and any overflows/overruns CRON generate backup and these are checked by the Sysop for issues in Callsigns and Radio ID numbers and RadioID's that do not match Callsigns and IP’s and login locations are captured.
The VKDMR server is a closes application. The source is not shared.
The IPSC source code is proprietery. It'sa development has been forked many times
and is modified and re-comfigured by many server admins. There is a connection
from Motorola's Mototrbo Server to IPSC to ISPC to UPSC2. They are all inovations
of bridging (inter-server-communications) applicartions that attempt to comply with the
DMR ETSI II standard.
My understanding is that the VKDMR is a linux server based upon DMR+ IPSC2 by
DG1HT DL5DI and OE1KBC.
