NAME¶
bbctl - query and control tool for BitBabbler hardware RNG devicesSYNOPSIS¶
bbctl [options]DESCRIPTION¶
The bbctl program can be used to issue command requests to the control socket of software controlling a BitBabbler device (such as the seedd(1) daemon).OPTIONS¶
The following options are available:- -s, --scan
- Scan for active devices. This will report the device identifiers which can be queried from the owner of the control socket.
- -i, --device-id=id
- Act on only the specified device. If no devices are explicitly specified then the default is to act upon all of them. This option may be passed multiple times to act on some subset of the available devices. The id must be an identifier name as reported by bbctl --scan, you cannot use device logical or physical addresses here.
- -b, --bin-freq
- Report the 8-bit symbol frequencies.
- -B, --bin-freq16
- Report the 16-bit symbol frequencies.
- --bin-count
- Report the 8-bit symbol counts. Similar to --bin-freq except the bins are reported in symbol order instead of sorted by frequency.
- --bin-count16
- Report the 16-bit symbol counts. Similar to --bin-freq16 except the bins are reported in symbol order instead of sorted by frequency.
- --first=n
- Show only the first n results. Useful when you don't want to actually see all 65 thousand entries for the 16-bit bins. The default (if neither this nor the --last option are specified) is to report everything in its full glory. Don't say I didn't warn you.
- --last=n
- Show only the last n results. Useful when you don't want to actually see all 65 thousand entries for the 16-bit bins. If used together with the --first option, then both the requested head and tail of the results will be shown.
- -r, --bit-runs
- Report on runs of consecutive bits.
- -S, --stats
- Report general QA statistics.
- -c, --control-socket=path
- The filesystem path for the service control socket to query. This can
belong to any process that supports the BitBabbler control socket
interface and for which the user running bbctl has permission to
connect to.
An address of the form tcp:host:port may be used if the control socket is bound to a TCP port rather than a unix domain socket path. The host part can be a DNS hostname or address literal. If an IPv6 address literal is used it should be enclosed in square brackets (e.g. tcp:[::1]:2020 to bind to port 2020 on the local IPv6 interface). The port can be a port number or a service name (as defined in /etc/services or other system name-service databases which are queried by getaddrinfo(3)).
- -V, --log-verbosity=n
- Change the logging verbosity of the control socket owner.
- -v, --verbose
- Make more noise about what is going on internally. It may be passed multiple times to get swamped with even more information.
- -?, --help
- Show a shorter version of all of this, which may fit on a single page.
- --version
- Report the bbctl release version.
FILES¶
- /var/run/bit-babbler/seedd.socket
- The default control socket path if not explicitly specified.
