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.

FILES

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

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.
