prngd. use it or not ?
 
is prngd good enough for entropy source ?

how good is prngd if it compare with /dev/urandom ?

From prngd README:
Quote:
- If you have a UNIX version providing /dev/urandom or /dev/random you
probably won't need PRNGD at all.
If was designed to replace /dev/urandom in systems that don't have it. If you want a good source, use /dev/random.

But, /dev/random can only be feed with mouse movement and keystrokes, IIRC.

i think /dev/urandom is better since it gather system entropy.

any suggestion ?

Both gather system entropy. The difference is that random stops when it doesn't have enough and urandom generates more data. It's theoretically vulnerable.
