NAME¶
imcadmin - Interplanetary Multicast (IMC) scheme administration interface
SYNOPSIS¶
imcadmin [
commands_filename ]
DESCRIPTION¶
imcadmin configures the local ION node's routing of bundles to endpoints
whose IDs conform to the
imc endpoint ID scheme.
imc is a
CBHE-conformant scheme; that is, every endpoint ID in the
imc scheme is
a string of the form "imc:
group_number.
service_number" where
group_number (an
IMC multicast group number) serves as a CBHE "node number" and
service_number identifies a specific application processing point.
imcadmin operates in response to IMC scheme configuration commands found
in the file
commands_filename, if provided; if not,
imcadmin
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
imcadmin with the 'h' or '?' commands at the prompt. The commands are
documented in
imcrc(5).
EXIT STATUS¶
- "0" Successful completion of IMC scheme administration.
- "1" Unsuccessful completion of IMC scheme administration, due to
inability to attach to the Bundle Protocol system or to initialize the IMC
scheme.
EXAMPLES¶
- imcadmin
- Enter interactive IMC scheme configuration command entry mode.
- imcadmin host1.imcrc
- Execute all configuration commands in host1.ipnrc, then terminate
immediately.
FILES¶
See
imcrc(5) for details of the IMC 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 ipnrc file on a
Windows machine, be sure to
use dos2unix to convert it to Unix text
format before presenting it to
imcadmin. Otherwise
imcadmin
will detect syntax errors and will not function satisfactorily.
The following diagnostics may be issued to the logfile ion.log:
- imcadmin can't attach to BP.
- Bundle Protocol has not been initialized on this computer. You need to run
bpadmin(1) first.
- imcadmin can't initialize routing database.
- There is no SDR data store for imcadmin 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
imcadmin 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
imcrc(5) for details.
