NAME

       lgsend - ION Load/Go command program

SYNOPSIS

       lgsend command_file_name own_endpoint_ID destination_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 lgsend program reads a Load/Go source file from a local file system, encapsulates the
       text of that source file in a bundle, and sends the bundle to an lgagent task that is
       waiting for data at a designated DTN endpoint on the remote node.

       To do so, it first reads all lines of the Load/Go source file identified by
       command_file_name into a temporary buffer in ION's SDR data store, concatenating the lines
       of the file and retaining all newline characters.  Then it invokes the bp_send() function
       to create and send a bundle whose payload is this temporary buffer, whose destination is
       destination_endpoint_ID, and whose source endpoint ID is own_endpoint_ID.  Then it
       terminates.

EXIT STATUS

       "0" Load/Go file transmission succeeded.

       "1" Load/Go file transmission failed.  Examine ion.log to determine the cause of the
           failure, then re-run.

FILES

       lgfile contains the Load/Go file capsules and directive that are to be sent to the remote
       node.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

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

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

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

       lgsend: can't open file of LG commands: error description
           command_file_name doesn't identify a file that can be opened.  Correct spelling of
           file name or file's access permissions.

       lgsend: can't get size of LG command file: error description
           Operating system problem.  Investigate and correct before rerunning.

       lgsend: LG cmd file size > 64000.
           Load/Go command file is too large.  Split it into multiple files if possible.

       lgsend: no space for application data unit.
           ION system problem: have exhausted available SDR data store reserves.

       lgsend: fgets failed: error description
           Operating system problem.  Investigate and correct before rerunning.

       lgsend: can't create application data unit.
           ION system problem: have exhausted available SDR data store reserves.

       lgsend: can't send bundle.
           ION system problem.  Investigate and correct before rerunning.
