dccpcli - DCCP-based BP convergence layer input task
dccpcli is a background "daemon" task that receives DCCP datagrams via a DCCP socket bound to local_hostname and local_port_nbr, extracts bundles from those datagrams, and passes them to the bundle protocol agent on the local ION node. If not specified, port number defaults to 4556. Note that dccpcli has no fragmentation support at all. Therefore, the largest bundle that can be sent via this convergence layer is limited to just under the link's MTU (typically 1500 bytes). The convergence layer input task is spawned automatically by bpadmin in response to the 's' (START) command that starts operation of the Bundle Protocol; the text of the command that is used to spawn the task must be provided at the time the "dccp" convergence layer protocol is added to the BP database. The convergence layer input task is terminated by bpadmin in response to an 'x' (STOP) command. dccpcli can also be spawned and terminated in response to START and STOP commands that pertain specifically to the DCCP convergence layer protocol.
"0" dccpcli 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 bpadmin to restart dccpcli. "1" dccpcli terminated abnormally, for reasons noted in the ion.log file. Investigate and solve the problem identified in the log file, then use bpadmin to restart dccpcli.
No configuration files are needed.
No environment variables apply.
The following diagnostics may be issued to the ion.log log file: dccpcli can't attach to BP. bpadmin has not yet initialized Bundle Protocol operations. No such dccp duct. No DCCP induct matching local_hostname and local_port_nbr has been added to the BP database. Use bpadmin to stop the DCCP convergence-layer protocol, add the induct, and then restart the DCCP protocol. CLI task is already started for this duct. Redundant initiation of dccpcli. dccpcli can't get IP address for host. Operating system error. Check errtext, correct problem, and restart dccpcli. CLI can't open DCCP socket. This probably means DCCP is not supported on your system. Operating system error. This probably means that you are not using an operating system that supports DCCP. Make sure that you are using a current Linux kernel and that the DCCP modules are being compiled. Check errtext, correct problem, and restart dccpcli. CLI can't initialize socket. Operating system error. Check errtext, correct problem, and restart dccpcli. dccpcli can't get acquisition work area. ION system error. Check errtext, correct problem, and restart dccpcli. dccpcli can't create new thread. Operating system error. Check errtext, correct problem, and restart dccpcli.
