What is a normal entropy_avail value for apache?


My entropy value is around 130-180 while a test script is running and 150-180 normally. Would that value have any bearing on static HTML pages that don't use any random() functionality? Or do all pages rely on the entropy? Also, what is considered to be a normal value? I've seen articles stating that value should be around 4094 if nothing is using it.


Solution

  • Sigh. I do not know why these programs insist on "true random" numbers when a cryptographic pseudo-RNG is perfectly adequate.

    That said, if you install rng-tools (or whatever package contains rngd), you will not have to worry about this. (Because the CPU has a hardware RNG built in.)

    I guess I am assuming this is a Linux system and a reasonably modern CPU.
