dtpcd - DTPC daemon task for receiving and processing DTPC ADUs in bundles
is a background "daemon" task that manages the reception
and processing of DTPC protocol data units. It receives the payloads of
bundles destined for the "ipn"-scheme endpoint whose node number is
the number of the local node and whose service number is the DTPC_RECV_SVC_NBR
(129 as of the time of this writeng).
DTPC protocol data units are of two types: application data units (ADUs, i.e.,
aggregations of application data items) and acknowledgments. Each
acknowledgment is interpreted as authorization to release the buffer space
occupied by the node's local copy of the acknowledged ADU. Each ADU is parsed
into its constituent application data items, which are then delivered to the
applications awaiting them, and when required a DTPC end-to-end acknowledgment
PDU is returned to the DTPC PDU sender.
- dtpcd terminated normally, for reasons noted in the
ion.log file. If this termination was not commanded, investigate
and solve the problem identified in the log file and use dtpcadmin
to restart dtpcd.
- dtpcd terminated abnormally, for reasons noted in
the ion.log file. Investigate and solve the problem identified in
the log file, then use dtpcadmin to restart dtpcd.
No configuration files are needed.
No environment variables apply.
The following diagnostics may be issued to the ion.log
- DTPC can't open own 'send' endpoint.
- Bundle protocol agent has not been started. See
- dtpcd can't attach to DTPC.
- dtpcadmin has not yet initialized DTPC protocol
