# Add extra options here
Hi Phil, I added the extra option then did the "service rngd start" and it works absolutely beautifully! Now there is plenty of entropy created when the java program runs, and I can repeatedly run the java program again and again and again and it completes instantly every time (virtually no wait), instead of taking minutes.
Before I get too overjoyed, can you help me understand what we just did? Does this solution enable rgnd to feed /dev/random with entropy from /dev/urandom? Or does it replace all of the entropy from /dev/random with entropy from /dev/urandom?
>If that works, then "chkconfig rngd on" will start it at boot.
That is, do I execute this from the command line (sitting at any directory)? Will this setting stick upon reboot if typed from command line?
... In either case, I assume to undo this I just do something like "chkconfig rngd off" (?).
