When no radioactive decay is available and good entropy is strongly advised for security reasons you experience a real problem. HTTPS connections consume a lot of entropy. If you have thousands of them per hour between machines low on good entropy (like deprived Web Servers at 4 o'clock am), your HTTPS (wget) poisen's your entropy pool. 'You become a victim of a 12 year old script kid'.

If I run Deezer (music) all the time, my entropy_available ['cat /proc/sys/kernel/random/entropy_available' when 'poolsize' in the same directory is 4096 should be full! 4096.] still went's down till I do some keystrokes. Then it jumps up more or some times less. I have no real good source of entropy here (only my selves - and even humans are deterministic). I am searching for a easy and cheap solution for 2 web crawler's 24 hrs online in a 'office' like setup. They ping each other and the router to distribute the (bad) entropy. I think of writing log's using a serial dot matrix printer to gather entropy mechanically (very noisy). The Sound Card Microphone is no good source of entropy. Short Wave Noise is as bad as a Microphone. The Bit rate is much higher on Short Wave. You can gather only 'White Noise' in this way. It's like playing the same 10 song's on Deezer's auto play for Years and Years. So Hardware without radioactive decay can't work on it's own. You need a thing to mix it with. This thing is GOOD entropy. Any experience with bad/poisened entropy on Linux?
