NAME

       lgagent - ION Load/Go remote agent program

SYNOPSIS

       lgagent own_endpoint_ID

DESCRIPTION

       ION Load/Go is a system for management of an ION-based network, enabling the execution of ION administrative programs at remote nodes.  The
       system comprises two programs, lgsend and lgagent.

       The lgagent task on a given node opens the indicated ION endpoint for bundle reception, receives the extracted payloads of Load/Go bundles
       sent to it by lgsend as run on one or more remote nodes, and processes those payloads, which are the text of Load/Go source files.

       Load/Go source file content is limited to newline-terminated lines of ASCII characters.	More specifically, the text of any Load/Go source
       file is a sequence of line sets of two types: file capsules and directives.  Any Load/Go source file may contain any number of file
       capsules and any number of directives, freely intermingled in any order, but the typical structure of a Load/Go source file is simply a
       single file capsule followed by a single directive.

       When lgagent identifies a file capsule, it copies all of the capsule's text lines to a new file that it creates in the current working
       directory.  When lgagent identifies a directive, it executes the directive by passing the text of the directive to the pseudoshell()
       function (see platform(3)).  lgagent processes the line sets of a Load/Go source file in the order in which they appear in the file, so the
       text of a directive may reference a file that was created as the result of processing a prior file capsule in the same source file.

EXIT STATUS

       0   Load/Go remote agent processing has terminated.

FILES

       lgfile contains the Load/Go file capsules and directives that are to be processed.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

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

       lgagent: can't attach to BP.
	   Bundle Protocol is not running on this computer.  Run bpadmin(1) to start BP.

       lgagent: can't open own endpoint.
	   own_endpoint_ID is not a declared endpoint on the local ION node.  Run bpadmin(1) to add it.

       lgagent: bundle reception failed.
	   ION system problem.	Investigate and correct before restarting.

       lgagent cannot continue.
	   lgagent processing problem.	See earlier diagnostic messages for details.  Investigate and correct before restarting.

       lgagent: no space for bundle content.
	   ION system problem: have exhausted available SDR data store reserves.

       lgagent: can't receive bundle content.
	   ION system problem: have exhausted available SDR data store reserves.

       lgagent: can't handle bundle delivery.
	   ION system problem.	Investigate and correct before restarting.

       lgagent: pseudoshell failed.
	   Error in directive line, usually an attempt to execute a non-existent administration program (e.g., a misspelled program name).
	   Terminates processing of source file content.

       A variety of other diagnostics noting source file parsing problems may also be reported.  These errors are non-fatal but they terminate the
       processing of the source file content from the most recently received bundle.
