ipnadminep - administrative endpoint task for the IPN scheme SYNOPSIS
ipnadminep DESCRIPTION
ipnadminep is a background "daemon" task that receives and processes administrative bundles (all custody signals and, nominally, all bundle status reports) that are sent to the IPN-scheme administrative endpoint on the local ION node, if and only if such an endpoint was established by bpadmin. It 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. ipnadminep can also be spawned and terminated in response to START and STOP commands that pertain specifically to the IPN scheme. ipnadminep responds to custody signals as specified in the Bundle Protocol specification, RFC 5050. It responds to bundle status reports by logging ASCII text messages describing the reported activity. EXIT STATUS
0 ipnadminep terminated, 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 ipnadminep. 1 ipnadminep was unable to attach to Bundle Protocol operations or was unable to load the IPN scheme database, probably because bpadmin has not yet been run. FILES
No configuration files are needed. ENVIRONMENT
No environment variables apply. DIAGNOSTICS
The following diagnostics may be issued to the ion.log log file: ipnadminep can't attach to BP. bpadmin has not yet initialized BP operations. ipnadminep can't load routing database. ipnadmin has not yet initialized the IPN scheme. ipnadminep crashed. An unrecoverable database error was encountered. ipnadminep terminates. BUGS

DTN2FW(1) BP executables DTN2FW(1) NAME
dtn2fw - bundle route computation task for the "dtn" scheme SYNOPSIS
dtn2fw DESCRIPTION
dtn2fw 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 STATUS
0 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. FILES
No configuration files are needed. ENVIRONMENT
No environment variables apply. DIAGNOSTICS
The 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. BUGS
