bpcp

BPCP(1) 							 CFDP executables							   BPCP(1)

NAME

       bpcp - A remote copy utility for delay tolerant networks utilizing NASA JPL's Interplanetary Overlay Network (ION)

SYNOPSIS

       bpcp [-dqr | -v] [-L bundle_lifetime] [-C custody_on/off] [-S class_of_service] [host1:]file1 ... [host2:]file2

DESCRIPTION

       bpcp copies files between hosts utilizing NASA JPL's Interplanetary Overlay Network (ION) to provide a delay tolerant network. File copies
       from local to remote, remote to local, or remote to remote are permitted.  bpcp depends on ION to do any authentication or encryption of
       file transfers.	All covergence layers over which bpcp runs MUST be reliable.

       The options are permitted as follows:

	-d  Debug output. Repeat for increased verbosity.
	-q  Quiet. Do not output status messages.
	-r  Recursive.
	-v  Display version information.
	-L bundle_lifetime
	    Bundle lifetime in seconds. Default is 86400 seconds (1 day).

	-C BP_custody
	    Acceptable values are ON/OFF,YES/NO,1/0. Default is ON.

	-S class_of_service
	    Bundle Protocol Class of Service for this transfer. Available options are:

	    0	 Bulk Priority
	    1	 Standard Priority
	    2	 Expedited Priority

	    Default is Standard Priority.

       bpcp utilizes CFDP to preform the actual file transfers. This has several important implications. First, ION's CFDP implementation requires
       that reliable convergence layers be used to transfer the data. Second, file permissions are not transferred. Files will be made executable
       on copy. Third, symbolic links are ignored for local to remote transfers and their target is copied for remote transfers. Fourth, all hosts
       must be specified using ION's IPN naming scheme.

       In order to preform remote to local transfers or remote to remote transfers, bpcpd must be running on the remote hosts. However, bpcp
       should NOT be run simultaneously with bpcpd or cfdptest.

EXIT STATUS

       0   bpcp terminated normally.

       1   bpcp terminated abnormally. Check console and the ion.log file for error messages.

FILES

       No configuration files are needed.

ENVIRONMENT

       No environment variables apply.
