NAME

bpsource - Bundle Protocol transmission test shell

SYNOPSIS

bpsource destinationEndpointId ["text"] [-t_TTL_]

DESCRIPTION

When text is supplied, bpsource simply uses Bundle Protocol to send text to a counterpart bpsink application task that has opened the BP endpoint identified by destinationEndpointId, then terminates.

Otherwise, bpsource offers the user an interactive "shell" for testing Bundle Protocol data transmission. bpsource prints a prompt string (": ") to stdout, accepts a string of text from stdin, uses Bundle Protocol to send the string to a counterpart bpsink application task that has opened the BP endpoint identified by destinationEndpointId, then prints another prompt string and so on. To terminate the program, enter a string consisting of a single exclamation point (!) character.

TTL indicates the number of seconds the bundles may remain in the network, undelivered, before they are automatically destroyed. If omitted, TTL defaults to 300 seconds.

The source endpoint ID for each bundle sent by bpsource is the null endpoint ID, i.e., the bundles are anonymous. All bundles are sent standard priority with no custody transfer and no status reports requested.

EXIT STATUS

  • "0"

    bpsource has terminated. Any problems encountered during operation will be noted in the ion.log log file.

FILES

The service data units transmitted by bpsource are sequences of text obtained from a file in the current working directory named "bpsourceAduFile", which bpsource creates automatically.

ENVIRONMENT

No environment variables apply.

DIAGNOSTICS

Diagnostic messages produced by bpsource are written to the ION log file ion.log.

  • Can't attach to BP.

    bpadmin has not yet initialized Bundle Protocol operations.

  • bpsource fgets failed

    Operating system error. Check errtext, correct problem, and rerun.

  • No space for ZCO extent.

    ION system error. Check for earlier diagnostic messages describing the cause of the error; correct problem and rerun.

  • Can't create ZCO extent.

    ION system error. Check for earlier diagnostic messages describing the cause of the error; correct problem and rerun.

  • bpsource can't send ADU

    Bundle Protocol service to the remote endpoint has been stopped.
