I am use to low random entropy on my arm boards, not an intel.
On my Lenovo x120e,
cat /proc/sys/kernel/random/entropy_avail
reports 3190 bits of entropy.
On my armv7 with Centos7 I would get 130 unless I installed rng-tools and then I get ~1300. SSH into one and it drops back to 30! for a few minutes. Sigh.
Anyway on my new Zotac nano ad12 with an AMD E-1800 duo core, I am seeing 180.
I installed rng-tools and no change. Does anyone here know how to improve the random entropy?
EPEL: yum install haveged
Another option involves open source hardware, at http://onerng.info/ which is a hardware entropy generator. Lots of discussion on how it works, and why.
the one I have doesn't seem to work on a usb3.0 port (on my desktop PC), but that may not be its fault.
