The BitBabbler is a hardware True Random Number Generator (TRNG)
manufactured by Voicetronix of Australia. This package installs the
software necessary to control and perform basic health checks on both
"white" or "black" varieties of BB devices. After installing this
package:
White and Black BB devices.
1. Add group "bit-babbler", or modify
/etc/udev/rules.d/90-bit-babbler.rules to use an existing group (e.g.,
"wheel" or "adm"). Beside root, only members of this designated group
will be able to directly access BB devices on your system.
After installing this package, you'll need to addgroup "bit-babbler"
OR: put a modified copy of
/lib/udev/rules.d/90-bit-babbler.rules
into /etc/udev/rules.d that uses an existing group (e.g., "wheel").
(So long as the filename is the same, the modified rules file in this
directory will override the original installed by this package.)
2a. Typically, you'll probably want your BitBabbler device(s) to start
feeding entropy to the kernel at boot. Include these lines in
/etc/rc.d/rc.local:
To also have your BitBabbler device(s) start feeding entropy to the
kernel at boot:
1) Add the following lines to /etc/rc.d/rc.local:
# Start BitBabbler TRNG.
if [ -x /etc/rc.d/rc.seedd ]; then
. /etc/rc.d/rc.seedd start
fi
2b. It is also a good idea to stop your BB device from feeding entropy
to the kernel before capturing the random number seed on
shutdown/reboot. Put these lines in /etc/rc.d/rc.local_shutdown,
which you'll need to create if it doesn't already exist:
2) And add the following to /etc/rc.d/rc.local_shutdown:
# Stop BitBabbler TRNG.
if [ -x /etc/rc.d/rc.seedd ]; then
. /etc/rc.d/rc.seedd stop
fi
3) Then be sure the execute bit is set (chmod) for rc.local,
rc.local_shutdown, and rc.seedd.
Enjoy!
