NAME

imcadminep - administrative endpoint task for the IMC (multicast) scheme

SYNOPSIS

imcadminep

DESCRIPTION

imcadminep is a background "daemon" task that receives and processes administrative bundles (multicast group petitions) that are sent to the IMC-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. imcadminep can also be spawned and terminated in response to START and STOP commands that pertain specifically to the IMC scheme.

imcadminep responds to multicast group "join" and "leave" petitions by managing entries in the node's database of multicast groups and their members.

EXIT STATUS

"0"

imcadminep 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 imcadminep.
"1"

imcadminep was unable to attach to Bundle Protocol operations or was unable to load the IMC 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:

imcadminep can't attach to BP.

bpadmin has not yet initialized BP operations.
imcadminep can't load routing database.

imcadmin has not yet initialized the IMC scheme.
imcadminep crashed.

An unrecoverable database error was encountered. imcadminep terminates.
