I want to continuously increase
/prco/sys/random/entropy_avail when it reduced.
I first check the
/dev/random is very slow since it only collects entropy from device drivers and other (slow) sources and I think that is why we use
And it says
rngd mainly uses hardware random number generators (TRNG), present in modern hardware like recent AMD/Intel processors, VIA Nano or even Raspberry Pi.
However, when I start
rngd it says
[root@localhost init.d]# rngd can't open entropy source(tpm or intel/amd rng) Maybe RNG device modules are not loaded
But I don't have Intel
RDRAND confirmed by
cat /proc/cpuinfo | grep rdrand:
[root@localhost init.d]# cat /proc/cpuinfo | grep rdrand | wc -l 0
If there is any possible resources that I can use?
Alternatively, is it possible making script to increase
