DTN2FW(1) BP executables DTN2FW(1)NAMEdtn2fw - bundle route computation task for the "dtn" schemeSYNOPSISdtn2fwDESCRIPTIONdtn2fw is a background "daemon" task that pops bundles from the queue of bundle destined for "dtn"-scheme endpoints, computes proximate destinations for those bundles, and appends those bundles to the appropriate queues of bundles pending transmission to those computed proximate destinations. For each possible proximate destination (that is, neighboring node) there is a separate queue for each possible level of bundle priority: 0, 1, 2. Each outbound bundle is appended to the queue matching the bundle's designated priority. Proximate destination computation is affected by static routes as configured by dtn2admin(1). dtn2fw is spawned automatically by bpadmin in response to the 's' (START) command that starts operation of Bundle Protocol on the local ION node, and it is terminated by bpadmin in response to an 'x' (STOP) command. dtn2fw can also be spawned and terminated in response to START and STOP commands that pertain specifically to the "dtn" scheme.EXIT STATUS0 dtn2fw terminated, for reasons noted in the ion.log log file. If this termination was not commanded, investigate and solve the problem identified in the log file and use bpadmin to restart dtn2fw. 1 dtn2fw could not commence operations, for reasons noted in the ion.log log file. Investigate and solve the problem identified in the log file, then use bpadmin to restart dtn2fw.FILESNo configuration files are needed.ENVIRONMENTNo environment variables apply.DIAGNOSTICSThe following diagnostics may be issued to the ion.log log file: dtn2fw can't attach to BP. bpadmin has not yet initialized BP operations. dtn2fw can't load routing database. dtn2admin has not yet initialized the "dtn" scheme. Can't create lists for route computation. An unrecoverable database error was encountered. dtn2fw terminates. 'dtn' scheme is unknown. The "dtn" scheme was not added when bpadmin initialized BP operations. Use bpadmin to add and start the scheme. Can't take forwarder semaphore. ION system error. dtn2fw terminates. Can't enqueue bundle. An unrecoverable database error was encountered. dtn2fw terminates.BUGSReport bugs to <ion-bugs@korgano.eecs.ohiou.edu>SEE ALSObpadmin(1), dtn2admin(1), bprc(5), dtn2rc(5). perl v5.14.2 2012-05-25 DTN2FW(1)
