The contents of this -buffer can be fed into the random device or accessed directly through the -file system. File system access is a useful alternative to those situations -where use of the random device is either inappropriate or not available. - -Add the following snippet to your /etc/rc.d/rc.M to start up haveged at boot: - -# Starting HAVEGED entropy daemon -if [ -x /etc/rc.d/rc.haveged ]; then - /etc/rc.d/rc.haveged start -fi - -You can see how many bits of entropy are available to the system by reading -the /proc/sys/kernel/random/entropy_avail file, and check the size of your -entropy pool at /proc/sys/kernel/random/poolsize. |
