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 开发者_开发技巧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.

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.
