            rtl2832_entropyd is a program that is designed to feed entropy into the linux /dev/random kernel entropy pool.  It automatically forks and runs as a daemon, unless one of the testing options, -o or -t, are selected.  Then it never forks.
To use it, you need an rtl2832 USB dongle.  They are relatively cheap (< $10 on ebay), and are actually used to listen to a broad range of radio transmissions.  This application exploits the radio noise in the atmosphere to extract entropy.  The kernel...
