NAME

       dtn2admin - baseline "dtn" scheme administration interface

SYNOPSIS

       dtn2admin [ commands_filename ]

DESCRIPTION

       dtn2admin configures the local ION node's routing of bundles to endpoints whose IDs
       conform to the dtn endpoint ID scheme.  dtn is a non-CBHE-conformant scheme.  The
       structure of dtn endpoint IDs remains somewhat in flux at the time of this writing, but
       endpoint IDs in the dtn scheme historically have been strings of the form
       "dtn://node_name[/demux_token]", where node_name normally identifies a computer somewhere
       on the network and demux_token normally identifies a specific application processing
       point.  Although the dtn endpoint ID scheme imposes more transmission overhead than the
       ipn scheme, ION provides support for dtn endpoint IDs to enable interoperation with other
       implementations of Bundle Protocol.

       dtn2admin operates in response to "dtn" scheme configuration commands found in the file
       commands_filename, if provided; if not, dtn2admin prints a simple prompt (:) so that the
       user may type commands directly into standard input.

       The format of commands for commands_filename can be queried from dtn2admin with the 'h' or
       '?' commands at the prompt.  The commands are documented in dtn2rc(5).

EXIT STATUS

       "0" Successful completion of "dtn" scheme administration.
       "1" Unsuccessful completion of "dtn" scheme administration, due to inability to attach to
       the Bundle Protocol system or to initialize the "dtn" scheme.

EXAMPLES

       dtn2admin
           Enter interactive "dtn" scheme configuration command entry mode.

       dtn2admin host1.dtn2rc
           Execute all configuration commands in host1.dtn2rc, then terminate immediately.

FILES

       See dtn2rc(5) for details of the DTN scheme configuration commands.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

       Note: all ION administration utilities expect source file input to be lines of ASCII text
       that are NL-delimited.  If you edit the dtn2rc file on a Windows machine, be sure to use
       dos2unix to convert it to Unix text format before presenting it to dtn2admin.  Otherwise
       dtn2admin will detect syntax errors and will not function satisfactorily.

       The following diagnostics may be issued to the logfile ion.log:

       dtn2admin can't attach to BP.
           Bundle Protocol has not been initialized on this computer.  You need to run bpadmin(1)
           first.

       dtn2admin can't initialize routing database.
           There is no SDR data store for dtn2admin to use.  Please run ionadmin(1) to start the
           local ION node.

       Can't open command file...
           The commands_filename specified in the command line doesn't exist.

       Various errors that don't cause dtn2admin to fail but are noted in the ion.log log file
       may be caused by improperly formatted commands given at the prompt or in the
       commands_filename file.  Please see dtn2rc(5) for details.
