NAME¶
bputa - BP-based CFDP UT-layer adapter
SYNOPSIS¶
bputa
DESCRIPTION¶
bputa is a background "daemon" task that sends and receives
CFDP PDUs encapsulated in DTN bundles.
The task is spawned automatically by
cfdpadmin in response to the 's'
command that starts operation of the CFDP protocol; the text of the command
that is used to spawn the task must be provided as a parameter to the 's'
command. The link service input task is terminated by
cfdpadmin in
response to an 'x' (STOP) command.
EXIT STATUS¶
- "0"
- bputa 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 cfdpadmin to restart
bputa.
- "1"
- bputa terminated abnormally, for reasons noted in the
ion.log file. Investigate and solve the problem identified in the
log file, then use cfdpadmin to restart bputa.
FILES¶
No configuration files are needed.
ENVIRONMENT¶
No environment variables apply.
