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.
