RHEL 7 Entropy mechanisms.

Share this link

Sometimes to get some entropy you have to do strange things.

Do you remember to make sudden mouse movements during SSH keys generation?

Where do this entropy come from? Why does everything sometimes seem stopped? How does it work for a virtual machine?

These are some of the questions discussed in the Random Number Generator tutorial.

I’m sure you will learn something.

I found it useful to do a “tcpdump -i any” to get some entropy.
